8. INTELLEGEICE_GENERAL SITUATION : NOV 1969 – JAN 1970
a. ENEMY STRATEGY: Since the death of Ho Chi Minh, the COSVN divisional forces worked basically to protect logistical routes and disrupt Vietnamization programs. It is not known whether this tactical change is a result of strategic implementation of “COSVN Resolution 9” by the Leo Dong, or the practical reality of heavy losses with few replacements, or if one caused the other, or both.
COSVN Resolution 9, as the Allied intelligence forces know it states means by which the VC/NVA hope to achieve total victory. It states that VC/NVA are to strive for American troop withdrawals, liberation of rural areas, destruction of RVN pacification teams, and the upgrading of the Provincial Revolutionary Government (PRG). For those purposes, the resolution states that an all-out attack strategy prevails. Engineer troops, sapper and armed reconnaissance teams and secret gorillas are to be used widely in tactical operations. Recent relocation of three main force Regiments from III Corps to IV Corps underlines their interests in the Delta. Present attempts at sapper training for sub-regional forces and an emphasis on resupplying them indicate the implementation of Resolution 9.
b. ENEMY TACTICS: The VC/NVA are now emphasizing economy-of-force measures, such as sapper probes, attack by fire and heavy mining of our communication lines, instead of large scale contacts.
In November 1969, main force enemy units avoided contact with the 11th ACR. Local force units mined LOC’s, attacked by fire, and sent small probes against RF/FF outposts. Mining incidents increased in December. Elements of the NVA 7th Division made contact in relocating from northwestern PHUOC Long Province to reoccupy areas north and went to LOC NINH. The 1/1st and 209th NVA Regiments of that Division remained along the northern periphery of BINH LONG and PHOUC LONG. They participated in the Corps-wide high point of 20-21 January. Other enemy unit identifications were Binh Long Provincial Force (D368 Local Battalion. Hon Quan and Loc Ninh Armed Forces and the IncLoc Administration) and specialized units, 225 Engineer Battalion, COSVN; the D 170th Independent Battalion, COSVN order security regiment, elements of the 50th and 70th Rear Services Groups, and a rear service element of the 69th Artillery Command.
c. JANUARY ENEMY SITUATION: Enemy forces in the 11th ACR TAO retained several option in January. They could launch sapper attacks, multi-battalion attacks, attack province and district capitals or increase their attacks by fire. They could harass installations, ambush and/or mine our roads, or avoid contact by withdrawing into Cambodia to escape Allied operations.
When in concentrated forces, the enemy remained vulnerable. Their supply system remained vulnerable to the Rome Plow and reconnaissance operations, while interdiction was their greatest hazard.
In Western Military Region 10, the week of 20-26 January had 21 attacks by fire, 26 mine incidents, 13 ground-to-air firings 5 attacked ambushes.
The relocation of the 7th NVA Division from Cambodia sanctuaries into the northern portion of the AO accounted for much of the activity. While their plans were unknown, it appeared that economy-of –force operations would prevail in February. This pattern was also followed throughout III Corps. In War Zone C, enemy forces continued to maintain pressure on fire support bases with attacks by fire. Although the 9th VC Division avoided contact during the wee, there were indications of ground and sapper probes in February.
The 1/1st NVA Regiment was identified by documents captured on 21 Jan by B/1/11 eight Kilometers out of Loc Ninh. Elements of the K22 Heavy Weapons battalion, 7th NVA Division and the 24th Anti-Aircraft Battalion, as well as the K4 Battalion of the 165th NVA Division were also tentatively identified. The C22 transportation Company and K1 Battalion, 1/1st Regiment were last identified in contact on 27 Dec 1969 NNW of Loc Ninh.
Documents taken from an NVA killed by G/2/11 on 23 Jan, three kilometers south of FSB Ruth identified the C3 Company, K7 Battalion, 209th NVA Regiment.
9. EXECUTION OF OPERATION: Operation FRESH START moved the Second Squadron to Eastern War Zone C to conduct Rome Plow operations, which would fix and destroy enemy forces there. The operational concept was for third Squadron to assume tactical control of the 984th Land Clearing Company. On 15 Feb 70 and escort them to positions near FSB Jan. The 984th LC Company would Rome Plow east to FSB Jan along Route 246. On 18 Feb, Second Squadron would assume tactical control of the 984th LCC and move thru the Third Squadron area of operations and begin the Rome Plow cuts in War Zone C., At this time, First Squadron would commander the operational control of the Third Brigade. The Third Brigade assumed responsibility for the 11th ACR AO and missions.
The First Squadron was given specific instructions to prepare to return to the 11th ACR control, to release control of 1 troop to 2-7 Cav, and to assume responsibility of one company of 2-7 Cav on 18 Feb 70. First Squadron was also to be prepared within capabilities to provide 1 LOH six hours daily to the Land Clearing Company.
Second Squadron was given the mission of sending one troop to secure the 984th LCC on 17 Feb 70 They were to prepare for the move into War Zone C and Rome Plow cuts by FSB Jan and the airstrip. The second Squadron assumed control of one company of 2-7 Cav. And secured the lines of communication from FSB Jan into War Zone C.
Third Squadron was given the mission of meeting the 984th LCC at FSB Thunder III on 15 Feb 70 and escorting it to FSB Jan. The Third Squadron and the LCC would then conduct a 400 meter cut Rome Plow operation along Route 246 between FSB Jan and the edge of the rubber (near XT696862.)
The emphasis and consequently the AO of the regiment shifted from North and Northwest of Quan Loi to an area South and East of that comp. Third Squadron had been operating in the area around Tonle Cham since the abortive Texas Traveler operation into War Zone C.
The bulk of the regiment had been to the north, Second Squadron had opened up a portion of QL 14 during November. Then for the second phase of Long Beach pushed on, with Rome Plows to Bu Dop, The First Squadron was located between the others, around Loc Ninh.
Deployment changed near the end of January, when the First Squadron moved to Eastern War Zone C, and became OPCON to 1st Bde. 1st Air Cav. Div. Initially, the Squadron conducted Rome Plow cuts along the major roads and trails around Bo Duc. Within weeks, this was altered so that they and the attached Rome Plows were working “tactical cuts” in an attempt to sever NVA supply lines.
2/11 had pulled back from Bu Dop, and during the first weeks of Feb. had the same general area that 1/11 had had in January around Loc Ninh. Meanwhile, to the South, 3/11 was still around Tonle Cham until they shifted to Loc Ninh, about 19 February. The Second Squadron, in turn, went past the Third’s old AO, and into War Zone C. Second Squadron went Rome Plowing to the east of First Squadron, where they stayed until the Cambodia invasion.
The Third Squadron stayed around Loc Ninh until mid-March, on reconnaissance and security duties, They were subjected to a great deal of enemy pressure, perhaps designed to make us reinforce them at the expense of the forces in War Zone C, and thusly take pressure from enemy supply lines. The enemy units further south desperately needed supplies at this time. Third Squadron was not reinforced but remained as an extra blocking force.
10. JANUARY OPERATIONS: First Squadron was ordered to begin its six-kilometer move from FSB Marge to FSB Dennis on the 16th, Actually, only B, C and HQ Troops, with the second platoon of the 919th Engineers, did so at that time, as the other company-sized units were controlled by other units: (A Trp. to 1st Bde, 1sy Cavalry. D Co. to the 199th Lt. Inf. Bde.) This move was within the same operational area, and was a continuation of the same general activities as had been going on. On that day, a platoon of B Troop secured FSB Dennis, while the Engineer platoon constructed it. Two kilometers further west, the rest of B Troop “reconned “ the heavy jungle. Squadron Headquarters prepared to move on the following day, with a C Trp, Platoon for perimeter security, while still at FSB Marge. C Troop (-), and the 196th Regional Forces Company reconncitered the area of rubber south of QL 14A.
On the next day, B TRp (-) reconned within one kilometer of Dennis, while one of its platoons escorted two 8-inch guns from Marge to Quan Loi. Another accompanied Headquarters to Dennis. C Troop, with the 213th Reg. Forces Company, moved north to QL 14a to operate.
The 18th of January, leaving a platoon to be LRRP and later secure Dennis, B Troop rumbled up QL 13 to reconnciter with the 294th Reg.F. Company north of QL 14A. Nearby to the Southwest C Troop pressed on thru the rubber, hunting the elusive enemy. Headquarters troop returned to Marge and continued closing it.
B Troop pushed further north on the 19th. Its remaining platoon was attached and divided between two demanding tasks: guarding the resupply convoy from Dennis to Loc Ninh, and and securing the fire base. C Troop moved within three kilometers of Loc Ninh, while their other platoon remained at Marge with the HQ.
On the Nixon Administrations First Anniversary, Headquarters Trp. Escorted the resupply convoy to Loc Ninh and back, which it did with some slight variations until the squadron got a new AO. Part of B Troop swept QL 13 from Marge north to the junction of QL 14A, and then again for about 12 kilometers south of Loc Ninh. C Troop moved 5 kilometers Northwest.
The next day’s search was successful when C Troop crossed QL 13 by Ap Loc Ninh (1) to recon. As they crossed the Buoi Nuu, they came under fire from two NVA battalions. B Troop rushed up. After the bitter battle was over, we had traded 1 U.S. for 35 enemy killed in action. There were also 7 GIs wounded while two ACAVs and two M551 Sheridans lost. B and C Troops were supported by TAC Air, their Regimental Air Cavalry, and Blue Max helicopters.
The day following, B Troop, with the 294th Reg. Force Co. moved to the north of the previous contact area, while C Troop maneuvered east of the area. Both were without contact.
January 23 saw the two Troops shift south of QL 14A, with B Troop east of QL 13 near Ap Loc Thanh (2). One of the platoons secured QL 13 from FSB Dennis to the junction of LTL 17 and provided escort vehicles to An Loc runs, C Troop worked just south of B (-) with the 293rd Reg Force Co.
B (-) moved around to their southwest with the 294th R.F., on the 24th.
A B Troop platoon swept QL 13 for 12 kilometers south of Marge the next day. B (-) and C Troops combined their forces to recon an area six kilometers east of the QL 13 and QL 14A junction. At XUP10140, they engaged an enemy force, killing two NVA soldiers.
Going a kilometer west from the contact of the day before, the two – Troop force made no contact.
On 27 January, the Troops worked separate areas with B Troop 5 km. Northwest of Loc Ninh, and C Troop near Dennis with the 294th Reg. Force Company.
In preparation for the 2/11th’s move from Bu Dop and the 1/11th’s from the area of operations, B Troop picked up the 196th RF Company and swept ten kilometers of QL14A. The units then established strong points to secure the road for a convoy of “low boys” to 2/11th ACR command point to pick up the Rome Plows. C Troop swept QL 13 to the south for about 10 kilometers.
B Troop repeated the action of the 28th, and when the convoy taking the Rome Plows passed them, they moved south to FSB Thunder III. C Troop swept QL 13 from Marge to the south for 12 kilometers to XT18980. One C Troop platoon escorted two 155mm howitzers to FSB Marge, after which the remainder of the squadron CP began to move, When HQ elements, four 155mm’s and the 2/919th Engineers all reached Marge, the forces mentioned that were there joined them, and the Squadron moved south to Thunder III. The First Squadron did not move down QL 13 until after the Rome Plows had passed on their way south.
The next day, the Second Squadron moved from Thunder III to FSB Carolyn and came under control of the 1st Brigade of the 1st Air Cav. Division.
That same day, Second Squadron moved into the Loc Ninh area to begin ground reconnaissance operations, to continue into mid-February. Headquarters Troop H Company a platoon of the 919th Engineers, and the Howitzer battery closed FSB Wade at Loc Ninh, XU32086. NDP’s were established as follows, at varying distances from Loc Ninh: E Troop, 7 kilometers NE, F Troop 4 kilometers north, and G Troop 3 1/2 kilometers south of the town.
Next day, the 30th, in the vicinity of XU9805136, E Troop made an FOB 5 kilometers west of Loc Ninh. At 1900 Hrs. an AB at XU822132 spotted six individuals who they engages with canister rounds. The following sweep produced a dead NVA, 3 SKS rifles, 7 NVA packs, a CCAM radio set, and some documents. There was also a trail of blood.
F Troop conducted reconnaissance from 30 Jan. thru 4 Feb. in an area 5 to 9 kilometers north of Loc Ninh. At 2335 Hrs. on the 31st an XU77816 area LP took 2 RPG rounds. 1st Platoon charged the enemy positions to the west. The RRF also took 2 RPG’s. One US GI was wounded but there was no other damage. Enemy losses are unknown. With Dawn, they found 6 2’X4’ bunkers, 2 mortar positions, 4 82mm mortar rounds, a fuse cap for an 81mm round and some C-Rations.
January 30, G Troop moved from an FOB 3 ½ km south of Loc Ninh to a new FOB at 688093, 5 km. West of the town. On the last of the month, after that day of maintainnencece, the Troop moved to Quan Loi and became OPCON to the 3rd Brigade of the 1st Cav. for several days.
11. FEBRUARY OPERATIONS: On January 30th, the 1st Squadron came under the operational control of the 1st Cav.’s 1st Brigade. LtC James Reed assumed command of the Squadron and led it on a road march from FSB Thunder III to XT277677. About eight kilometers from Nui Ba Den. During the march, they swept critical portions of the road from XT994547 to XT484469. For such a large sweep, the new commander used a new technique. LtC Reed took responsibility for the entire route, spacing two teams at the end of the area. At each end, one team started to sweep in, while the other went around to a point midway to the center, where it then started to sweep toward the center. When the outer teams had swept to the points where the inner ones began, they were airlifted to the center. From there they swept outwards until meeting the two teams from the halfway points. This was a reduction in time, and number of airlifts.
Despite this faster sweep method, the movement was still a problem because of its size. This is shown by a reference from the radio log of the Squadron to HQ at 0650Hrs.” In the combat vehicle convoy, there will be 39 vehicles in the first serial, 20 in the second, 42 in the third, and 38 in the fourth serial.” Despite these problems, the movement had reached its destination by 1800hrs. (Note: HQ, Howitzer Battery, with the 501st Land Clearing Company (& Rome Plows). C Troop was at XT34449),
The last day of the month was spent within the AO, securing the LCC, and in securing a LZ for the D/2/8th Cav., which became OPCON to 1/11th ACR.
By 0745 hours., C Troop had left their NDP southwest of Tay Ninh, and were heading for Christine. A Troop, which had spent the night at that base, moved southwest to support an ARVN contact at XT2281. B Troop secured the Rome Plows as they began to cut. Late in the afternoon, the Squadron CP, Howitzer Battery, Headquarters Troop, A Troop, and Rome Plows were at Christine. B Troop and M Company were to the northwest at XT324884.
Leading off the new month, the Squadron secured the 501st LCC while they worked along TL4. B troop went north and west to recon the area four to five kilometers away. That night, they stayed in the same area that they had the night before.. At 820hours M Company left their NDP at XT916885 to pick up the convoy at Christine, with a damageless mine-hit enroute. The convoy force departed for Carolyn, at 0936hrs. reaching it in about an hour., and then moving south toXT279680, where they met the convoy at 1340hours. The convoy reached Christine at about 1700hours. During the day A Troop remained at the FSB for maintenance.
The second platoon of M Company escorted 2 eight-inch howitzers to Christine from St. Barbara the next day, while the remainder of the Company operated near Ka Tum. At 1230, one of their tanks was destroyed by a mine, but without human casualties. Easterly they found a recent trail used within 24 hours. The Rome Plows continued to work along TL4 north of Christine, secured by A Troop. B Troop reconned the area southwest and west of Ka Tum. At XT198853, the enemy had set up anti-aircraft emplacements, from which they engaged a number of helicopters. That area was shelled with unknown results, by the organic artillery.
The Squadron’s situation continued without major incident for the next four days, up to the 7th when b-52 strikes were called in on suspected enemy positions. A Troop, along with B/2/7 and D/2/8 had to de lay there operations until two b52 strikes were completed within the area. A Troop, D/2/8, and Rome Plows moved south of Ka Tum, across highway 246, to an area about 5 kilometers east of Ka Tum. In the afternoon, this element began cutting into an area of bunker complexes. At 1550hours, they received RPG and small arms fire. They returned the fire and were supported by artillery and Blue Max. At 1745 the fighting ended with 14 NVA known dead. US wounded included 9 Medevaced out of 16. B Troop moved to the contact from Ronda (XT76864) to help secure the Rome Plows and act as a blocking force at XT411868, without contact. M Company worked with B/2/6 in reconning the bunker area near Ronda, but also made no contact. (see after-action interview report.)
Team A, on 8 Feb (A Troop and 2/2/8 moved from the NDP XT88887 into the bunker complex where the contact of the 7th occurred. A 1st Cav tracker team aided them, but unsuccessfully. Before twilight, they moved to the south to XT39849 and a new NDP, setting an ambush near Bu Dop that night. Team B provided security for the Rome Plow Company in their move from Ronda to FSB Eric (XT408440), assisting in building and securing the new base. M Company moved north from their NDP to pick up the Rome Plow that was damaged by the RPG fire on the day before and hauled it to leave it at Ronda. The tanks continued to Christine, where they became the base’s ready reaction force. 2/919th Engineers swept the roads from Christine to Ronda, finding 4 mines.
Everything went smoothly, with unchanged missions on the ninth. The Engineers swept north from Christine, and then on 246 from Ka Tum to Ronda. A Troop reconnoitered-about 5 kilometers north of Bu Dop, while B Troop secured the Rome Plows.
There was no enemy contact on the tenth, either. Most significant was the move of the CP to FSB Cindy (XT82815) which took almost 4 hours from 1010 to 1355 hours. A Troop and A/2/8 continued to the north of Ronda, returning to NDP at XT394849, east of Bu Dop.
A Troop left their NDP at 705 to set up strong points along the road from Ka Tum to Carolyn, in order to secure the 1st Brigade’s convoy. B Troop secured the Rome Plows on 246, to the southwest of Eric. A/2/8 reconned to the southwest of Eric, but made no contact, while M Company moved Northwest of Cindy for the same purpose. 2/919 swept from Ronda to Beverly. During the day, an m-88 from headquarters trp. hit a mine atXT371864, and became a combat loss, but without causalities.
During the twelfth, A Troop was contactless in a sweep reconning the dense jungle northeast of Ronda. B Troop secured the Plows as they pushed south near FSB Ted, which the 2/919 spent the day building. Later the 1st Bde. Radioed that Eric was to be used “on an active basis” which meant that B Troop would return to Eric rather than stay there. The plows were directed to cut in this triangular area for only 2 to 3 more days. M Company reconned south of Cindy, where they found old trench lines and bunkers near the FSB and destroyed them. The Headquarters ACAVs were returning from their water point to Christine when they spotted an NVA, who jumped into a bomb crater to hide. He was captured by the Squadron Commander who landed his helicopter and captured him.
Friday the thirteenth was much more innocent than its reputation, being without contact and continuing the missions for the previous day. A Troop reconned northwest of Ronda, B Troop secured the plows south of Ted, and M Company operated around Cindy.
The next day, A Troop reconned in the northern part of the AO, B Troop secured the Rome Plows cutting on route 246, M Company reconned north of Cindy. There not being even a contact, St, Valentines day was massacreless. C Troop however had a sharp engagement in which they lost several dead and hit, (probably the headquarters detachments) of the 272nd VC regiment, with a platoon of M Company. This story is told in the Combat After Action Report. There were seven dead and 27 wounded.
On the 15th C Troop, and C/2/8 swept through the battle area, noting a total of 45 enemy dead and the stripping of the abandoned tanks. The rest of M Company stayed in Cindy and overhauled their vehicles, while a platoon secured the water points. A Troop left Cindy in the morning for Carolyn, where they went OPCON to 2/8 Cav. One of their vehicles hit a mine at XT96830, wounding two.
The following day, M Company reconned southwest of Cindy and B Troop secured the Rome Plows near Ted. Late in the afternoon 2/919 Engineers and the H Company platoon again swept the area, finding many items and with an M-48 tank and a M551 Sheridan hitting mines. There were no casualties and little damage.
At 0025 the radar at Cindy picked up movement, located at 250 meters from the perimeter, and heading in the direction of 3190 mills. The “dusters” fired into the area, and the movement ceased. 1st Brigade radioed at 0610 to ensure that the First Squadron remove all vehicles to prevent the use of them for propaganda purposes. 2/919 left at 0830 to sweep north again for mines. B Troop, with the plows went on cutting to the southwards of Cindy with the Rome Plows. M Company remained in Cindy as a reserve action force.
On the 18th, B Troop and the 501st Land Clearing Company went on cutting south of Cindy. They proceeded from XT83756 to XT382780, and stayed that night at FSB Sara (XT 386755) which was nearby. To the north, HHT and the Engineers secured Cindy. M Company spent the day sweeping 246 for the three or four kilometers east of Bu Dop, and then set up screens down the road. Where 246 crosses Suoi Ngo, the culvert was damaged and the 1/11 required more equipment to repair it. They radioed for an airborne bulldozer to help repair it, and were on the phone again at noon to request help on disarming a 500-pound dud bomb from an EOD team. At this point the Squadron was returned to the 11th ACR’s control from 1st Bde.1st Cav. control.
At 0822 the next morning, some tracks from Headquarters troop had to secure the erdalator the convoy was ambushed when only a few kilometers north of the FSB. They were hit with two RPG’s, 4 mortar rounds, and some 51 caliber machinegun fire. One ACAV was hit, with two wounded, who were the medevaced to Tay Ninh. The convoy then continued on to the erdalator site near Bu Dop. They returned to Cindy, that night and joined M Company, which had remained there. Meanwhile, the Engineer platoon had swept their way along the road to Bu Dop, and about 3 km. Further northwest on 246. As B Troop secured the Rome Plow forces, they cleared 310 acres of jungle and returned to Sara for the night. During the day, a message was received about the bulldozer, and said that it would not come that day.
It did come the next day however, and, while M Company remained with Cindy, one of the platoons went with the 2/919th Engineers to replace the damaged culvert at the junction of 246 and Suoi Ngo. They went thru, to a point about three kilometers east and south of Bu Dop, when a T46 mine in the Rome Plow cut east of the road demolished a tank tread, but without human injury. At 0838, an Engineer ACAV hit another T46, which wounded a GI, and made the ACAV a total loss. Upon reaching the place, the engineers rapidly worked to install the new culverts. They radioed back at 1209 that the first section was in, and the second was to be finished soon. Instead of forming an NDP nearby the party returned to Cindy after completion of the task, since the Squadron had decided to place H & I fire on the point. B Troop and the Rome Plows continued to erase jungle along the Mustang. At 1800, they reported from the NDP at Sara that they had cleared 100 acres. 1st Cavalry Divisional G-3 told the Regimental S-3 at 2050 that “C Troop will recon from St Barbara to Carolyn on 21 February. Upon reaching Carolyn it will become OPCON to 1/11th ACR”
21 February: The platoon of Engineers working with the M Company plt. Swept north from Cindy along the Mustang Trail to 246, and returned from there for the night. B Troop, still securing the plows, spotted some movement to the west, which they engaged with artillery, but without any positive result. They cut 102 acres before returning to Sara. Headquarters Trp. lost an M578 to a mine. The ACAV’s were moving to secure the erdalator, at which point it hit a 23-pounder., but without casualties. Finally, at Cindy at 1600 hrs., C Troop returned to 11th ACR OPCON. They began some much needed maintenance.
On Washington’s birthday, a platoon of M Company secured the 2/919 Engineers as they swept eastward on highway 246 from Bu Dop, 8 kilometers to the Suoi Ngo. At XT409841, at 1310, they discovered a north-south enemy trail. It had been used by 4 to 6 people, about 15 hours earlier, but there was no one there at this time. B Troop guarded the plows, which cleared 131 acres, before retiring to Sara for the night. C Troop at Cindy would continue maintenance. At 0920, the CP received word that A Troop would continue to be OPCON to 1st Cav’s 1st Bde for three more days, since they were needed as convoy escorts to Ka Tum. At 1540 hours the calm was broken by incoming, as the CP received 4 rounds of 60mm mortar fire within the perimeter. There were no casualties. That evening, M Company, C Troop, Headquarters Troop and 2/919th were at Cindy. About 2207 hours, 1/11th was told that they would secure 8-in. howitzers from Cindy to the 1st Brigade boundary, “ Time and coordination to be announced.”
Following that, the units kept up their particular patterns of previous days. B Troop with the Rome Plows, 27 of which were working near Sara and to the south cutting 155 acres. 2/919, with a platoon of M Co. swept the same 8 kilometers east of Bu Dop, while C Troop worked on the vehicles at Cindy. Later in the day, 1st Bde announced the “ Time and Coordination for escorting the 8-inch guns through the AO to their own AO – 0800 next morning. At 2230, 1st Cav. Divisional G-3 radioed that the squadron would make tactical cuts to the north. 1/11 also tried to obtain a dump truck and a front end loader to aid them in crossing three streams.

12. Intelligence for February: From 9 February to the end of the month activity remained at a low level since enemy actions were light economy- of force measures. These were ambushes, attacks-by-fire, ground-to-air firings, and mining measures. The enemy appears to be receiving some replacements from North Viet Nam, and it is believed that the main force units are undergoing a period of resupply and refitting during the assimilation of the new arrivals. Enemy activity from the ninth in the 11th ACR tactical area of operations had been highlighted by 102 cases mining, five attacks-by-fire, and the 7th NVA Division’s intentions were unknown. The 141st and 209th NVA Regiments continued to maintain a presence along the border areas in Loc Ninh and Bo Tuc Districts. The 165th Regiment had been contacted moving south into War Zone C from the Fishhook. This deployment of the 165th possibly indicated that the 7th NVA Division will operate in a split configuration or intends to relocate from its traditional operations in Binh Long Province. The 9th VC Division had withdrawn northwards towards Cambodia from War Zone C. Its exact intentions are unknown, but reports tend to indicate that the two regiments may relocate to IV Corps.
Documents captured by D/2/5 Cavalry when it was OPCON to 11th ACR identified the C71 Company, D368 Local Force battalion, C31 Local Force battalion, C31 Local Force Company of Loc Ninh District, and the LBN of Binh Long Province Party committee, east and northeast of Loc Ninh. On the 19th of the month, S3/2/11, flying a LOH, killed two soldiers and captured documents which indicated the C29 Flamethrower Company, 7th NVA Division and indicated that this unit may have recently been trained in the use of the B20- probably a new type of oversized 107mm rocket. Four days later, from a hand-drawn map, the 654 Depot, 50th Rear Service’s Group was identified. From the 24-to the 28th, Second Squadron, operating in Eastern War Zone C, identified elements of the 165th NVA Regiment. On th 24th and 25th documents were found identifying the K5 and K6 battalions. Documents captured the next two days confirmed the presence of these units.
On the last of the month, documents from a POW and automatic-ambush identified the K28 Battalion, 212 B, and C1 and Ck, elements of the Division. Infiltration Group 312 is known to have supplied replacements to the 209th NVA Regiment of the same division.
The 11th ACR continued Rome Plow operations, providing for the security and conducting armored recon missions into March. They encountered light and scattered enemy activity. The 7th NVA and 9th VC Divisions, and logistical elements of the 59th Bear Services Group appeared to be using natural terrain cover and concealment to conduct recon missions, resupply operations and to harass NDPs. The enemy relied heavily on economy of force measures such as on-and-off road mining, attacks by fire, ground to air firings, and attempted ambushes. From 18 February to 19 March the enemy focused his attention on the Bo-Tuc Mustang Trail area, whereas he had previously (18 Feb to 2 Mar) concentrated his supply efforts and recon missions from the Fishhook down along the Saigon-Michelin Corridor. In that corridor, elements of the 165th NVA Regiment, 50th BSG, and the 96th Artillery Group were contacted and identified. In War Zone C, later, the 95C Regiment fought three major battles. As of 19 March, the situation remained fluid. Main force enemy units remained in or near the Cambodian Border, receiving replacements, training and refitting. The possibility of a large redeployment made the enemy’s intentions and locations difficult to estimate. It is believed that the 95C NVA Regiment remained in the Bo Tuc area; the 165th Regiment near the Fishhook; and the 50th RSG along the Saigon – Michelin Corridor. These units, as well as COSVN and border security elements played a threat to 11 ACR and nearby allied units.
On 19 February, the S3/3/Battalion was flying in a LOH, spotted and killed two NVA soldiers at XT513898. Documents from the bodies identified the C29 Flamethrower Company. 7th NVA Division, which was the first indication of that Divisions interest in War Zone C.
On the 24th of February, the K5 Battalion, 165th Regiment was identified by documents captured at XT535882, and further pinned by documents captured the next day in the same area, and at XT507802.
13. March Operations. After the move of the First Squadron command Post south to Sara, the Rome Plow operations did likewise. However, two of the troops remained in the northern portion of the area of operations to recon and screen. While M Company and Headquarters Troop remained at Sara, B Troop and the Rome Plows moved down the Mustang trail to about six kilometers south of Sara and established a defensive perimeter atXT417692. A Troop, reconning north of Bo Tuc, found a large bunker complex containing over 100 bunkers, and the grave of three NVA soldiers, They also discovered six B40 rounds, four B40 boosters, 500 AK47 rounds, fourty .51 caliber rounds, thirty grenades, 22 pounds of rice, medical supplies, documents, four .82mm mortar rounds, and other miscellaneous equipment.

At 2005, while on reconnaissance, they found a bicycle, four 82mm mortar rounds, two 57mm recoilless rifle rounds, and bunkers. C Troop, operating to the east of A Troop, hit a 23-pound mine causing negative casualties. That night, they set out 3ambush positions, with no results. To the south, near Sara, was set out an automatic ambush, near XT380760. At 1840 hours, while still emplacing the ambush, they were fired upon from the north. They quickly returned the fire and swept through the area. They found no enemy, but discovered a bunker complex with many cooking utensils scattered about! The Squadron also received word that D Company, which had been working with the 199th Lt. Inf. Bde. Was in Bien Hoa, and would become OPCON to the Squadron again at 1100 hours the next morning.
On the second of March, B Troop secured the Rome Plows as they cut 224 acres in the area from Vickie to five kilometers to the south. At 1115 hours, at XT405571, the enemy fired at the Rome Plow drivers wounding two of the (Viet Namese) drivers. After the brief encounter, the plows continued to cut the jungle. About one kilometer south of B Troop, the 3/9/919th constructed a bridge at XT408675. Further north on the Mustang Trail, M Company escorted a convoy to Bo Tuc. Just north of Sara, they found a fresh trail running thru the bamboo. Later, at 0933 hours, two of their M48 tanks hit 20-pound mines. Despite heavy damage, there were no human casualties. Also near Sara, they found 2 bunkers measuring 4x6x3 feet, with eight inches of overhead cover at XT378763. To the west they discovered and destroyed an L-shaped bunker which seemed to have seen recent use. Both A and C Troops reconned in the portion for the Squadron’s AO. A Troop XT3687, 4187,4180, 3680. C Troop XT4385, 4785,4781,4381. In the early morning before these operations began, an ambush from C Troop was in heavy fighting. The enemy had slipped up on the position, and fired in B40 rockets and hand grenades. One GI was killed, and four wounded by fragmentation. By 0420, Red 23 (Cobra from the Air Cav Troop/11th ACR) was straffing the area into which the enemy probably withdrew. Artillery also pounded that area. A Trooper reported that one of the enemy spoke English. At first light, they swept the area, and found 5 B40 rounds, ten grenades, and a flashlight. At 1017 hours, while on a ground reconnaissance at XT406851 they found fiftyfour 60 60mm rounds, six 82mm rounds, a small amount of AK ammo, and one blood trail leading from the area. A Troop had no contact during the day, but found twelve pounds of NVA clothing, 100 rounds of AK47 ammo, and cooking utensils at XT393852.
The patterns of the previous few days continued on March 3. A and C Troops screened and reconned the northeastern portion of the AO while the remainder of the units worked near Sara, or in B Troop’s case, south of there with the Rome Plows. A Troops assigned area was a rectangle with the following coordinated corners: XT3687, 4187, 4180, 3680. While in this area, they found a bunker complex at XT64836, containing many bunkers measuring 8x4ft. with one foot of overhead cover. Also in one of these enemy bunkers, A Troop found an old an unusable, .51 caliber Machine gun. Later, while reconning, they found the following: 850 rounds of ,51 caliber ammunition, 450 .30 caliber rounds, 21 rifle grenades, 1 T46 mine, One ChiCom Claymore, a .51 caliber site, bolt, guide and 2 feeders. 100 feet of commo wire, 4 ChiCom grenades, 2 bicycles, cooking utensils, and 20 pounds of clothing. Traveling northward (XT383824), one of the troop vehicles set off an anti-personnel mine, which caused no damage. About a half hour late, at 1930, an A Troop ambush position spotted three enemy at XT388833, and killed two of them. Also in this contact, were captured 2 AK47s and other miscellaneous equipment. To the east of A Trp. lay C Troop’s area, which was a triangular shaped plot from XT4784-4787-4184. The spent the day without contact. At night they set up two ambush positions at (XT442822, and XT417861) which they ringed with automatic ambushes at XT442822, 441822, 416819, 459819, and 420857, all without effect. To the south M Company secured Sara, pulled maintenance, and secured the erdalator. Still further south, along the Mustang Trail, B Trp. guarded the plows, which cut 178 acres with 28 operational plows. During the day, B Troop found a mine, which they blew in place. At night they set up two automatic ambushes, which had no results. At XT40876, the 3/919 continued to construct the bridge.
A Troop reconned the following day within the following coordinates: XT3783, 4083, 3787, 4087, without contact At night, they emplaced three automatic ambushes in addition to two ambush positions. C Troop made a long southerly reconnaissance that wound from XT4784 west to 4484, and eventually, south to the 79 grid line. At 1320 hours, the Troop moved to XT4686, where a pink team had seen 6 NVA. In a ground recon of that area they found a large complex containing 40 bunkers with tunnels and trench systems. Some of them had been used as recently as one or two hours, by about ten men. In the bunkers were three B40 launchers, three ChiCom grenades, clothing, a bicycle, two B40 rounds, and documents. The bunkers were destroyed. One platoon from M Company escorted two 8-inch howitzers to Cindy, where they conducted an artillery raid in the northern part of the AO. The rest of the company stayed at Sara. D Company moved from Bien Hoa to Tay Ninh during the day. They spent the last few days on a maintenance standdown after their OPCON to the 199th LIB. The 3/919 spent the day constructing a bridge at XT396633 but returned to B Troop’s NDP at night. The Rome Plows, secured by B Troop, cut 125 acres and reached a position about eight kilometers south of Sara.
5 March; (A or E) Troop maneuvered west of Bo Tuc in their search for the enemy from their area XT360840, 385908, 410883, 410840. At 1615 hours, they became OPCON to the 1st Bde, 1st Cavalry Division. C Troop worked in the area east of Bo Tuc (XT4184, 4187, 4784, 4787). At 1150 hours, in the jungle about 4 kilometers south of the Cambodian border at XT548862, they came upon enemy forces, well entrenched in bunkers. While C Troop maneuvered against them, the enemy responded with a hail of RPG’s and 60-mm mortars. Artillery, helicopters, and TAC jets all bombarded the area. One ACAV was heavily damaged by RPG fire and six troopers were wounded. After the fighting ended, 17 NVA dead were counted. That night, they formed their perimeter about 5 “klicks” east of Bo Tuc. They set out an ambush position and five automatic ambushes nearby. To the south, the Rome Plows with B Troop cleared 150 acres from XT406693 to 414634. In the afternoon, B Troop lost a Sheridan being towed by another vehicle, when it hit a pressure detonated mine. D Company evacuated downed vehicles from St. Barbara to Christine to Tay Ninh, and spent the night there. The engineers continued the bridgework at XT3996633, and M Company secured Sara during the day. At 1240 hours, at XT380770 the First Squadron C&C ship received ground-to-air fire. The helicopter sprayed the area, and artillery was called in, with unknown results.
During the sixth, C Troop operated alone in the northern portion of the AO. (from XT4184, 4187, 4787, 4784). At 0945 hours on a recon mission, near XT415845 just north of hiway 246, they came upon a unit of the 3rd Battalion, 95C Regiment of the 9th VC Division. While the tracks of C Troop pushed toward the enemy, artillery, light fire teams, and TAC jets supported them. Two CS drops were also brought in to pry the tenacious enemy from their positions. By 1230 hours, the contact was over with the VC fleeing in an unknown direction. Leaving 3 killed in action, 17 by artillery, and 11 by helicopters for a total of 31 dead. C Troop had three wounded. When they swept thru area, an ACAV detonated a mine. But with belly armor there were no casualties and light damages. About three hours later in the same area, the entire scene was repeated with the same results. At 1750 hours at XT415843 two vehicles were heavily damaged by mines. One was a previously damaged ACAV, which was being towed when it hit a twenty pounder. At the same time and location, a Sheridan, which was towing a vehicle, hit another twenty-pounder. To the south, B Troop secured the Rome Plows, but it reacted when C Troop made contact and most of it assisted in sweeping the area. Meanwhile, one platoon stayed with the plows as they continued to cut 136 acres down to LTL13. Headquarters Troop had a small contact at XT390783 while securing the erdalator. The enemy used small arms fire and B40 rockets, while HHT countered with organic weapons, a light fire team, and artillery. The contact broke immediately, without casualties. M Company (-) remained as a ready reaction force at Sara. One of its platoons escorted an AVLB to XT397633 near LTL13, so that D Company could cross the obstacle when it arrived there from Tay Ninh. Before it got to this crossing site, a D Company tank hit a mine buried in the shoulder of LTL13. They continued on, spending the night at XT414665 along the Mustang Trail, 3 kilometers north of LTL13.
Rome Plowing ended with 7 March for the ACR. B Company escorted the 501st LCC to Brant where that unit was released from First Squadron control. Before that, however, 3 Rome Plow people were injured when they found a wooden box, opened the lid, and it exploded. C Trp, to the north was bombarded wit RPGs and mortars outside their NDP at 0630 hours. The Troop returned the fire, with helicopters and artillery supporting. By 0700 hours, the fire stopped leaving an ACAV badly damaged, and nine US wounded. During the day, C Troop (-) conducted maintenance operations at XT405839 while one platoon swept the road from Cindy to Eric to the Bangal Bridge. At 1120 hours the Troop found a mine near their NDP and blew it in place. D Company moved to Sara and joined M Company, which was there for a maintenance standdown. At 1845 hours, Sara received 18 rounds of 60mm mortar fire from the east, all of which hit outside the perimeter without damage.
B Troop began doing purely recon operations, without the Rome Plows to secure. Their Troop AO had the following boundary points: XT380840, 410840, 41o884, 380863. Despite hard work in the jungles around Bo Tuc, they were contactless. Near their NDP at Rhonda, they found a mine in the middle of the road at 1818, and set out an ambush position during the night. It was to the southeast at XT385849. D Company swept the road from Cindy to Bo Tuc, and then down hiway 245 to Sara’s Area XT415836. Afterwards, they reconnoitered the area east of B Troop’s AO (which was XT4184, 4384, 4186, 4386). The tank company made no contact, and made their NDP at Sharon. To the east of D Company was C Troop’s AO (which was XT4481, 4684, 4484). Before beginning to recon, they swept the road from XT415836 to XT463818. That night they spent at XT438834. Nearby, they set up an AP (XT4338040) and four automatic ambushes. The 3/919th Engineers swept the dirt trail from Sarah to Cindy and then continued on to Sharon for the night. M Company moved to Sara where they spent the night. While M Company moved south, the CP moved from Sara to Sharon. The advance party arrived at 0900 hours and the main body was all at there by 1720 hours. While the 1/11th Command and Control ship was flying over the area, an enemy soldier fired at it with an AK47. The ship was hit twice, and one man was wounded, at XT387770.
The Squadron lost M Company on the 9th of March. They moved down hiway 246, and by noon had crossed the Bangal Bridge and were again OPCON to the Third Squadron. They went to Quan Loi. That same day, the First Squadron received as OPCON B/2/7. This infantry unit set out ambush positions along a trail northeast of Sharon as well as four auto ambushes. D Company secured Sharon while engineers worked on its fortifications. C Troop swept 246 from Sharon to XT463819, the bridge across the Suoi Ngu. B Troop was shelled at 0732 hours at XT380857 by two volleys, which impacted between 300 and 800 meters from their NDP. Troop personnel estimated that they were fired from the north at a reading of eight degrees. A few rounds more came in later, brining the total to 16. Artillery and helicopter gunships bombarded the suspected firing area, with unknown results. For the rest of the day, the Troop swept and screened 246 from Rhonda. At 0945 hours, while on the sweep, they discovered a T46 mine ten meters south of the road at XT411837, which they destroyed before continuing the sweep. That night’s NDP was at XT387857. Around it were two ambush parties, (XT81848 and XT387848) plus three automatic ambushes.
March 18th was to be the day of an attack on Objective Number 6, at XT410878, which was the location of the 95C Regiment, B Troop and D/2/7 were to spearhead this attack and they were to be reinforced by D Company. C Troop was to move to XT4444856 southeast of the objective and be prepared to reinforce if needed. Before the attack, there were to be three airstrikes around the objective. (XT415875, Xt410875, and XT421880). At or about 0745 hours elements of B Troop and D/2/7 moved from their respective NDPs to link up and move towards the objective. At 0820 XT405846 B Troop was ambushed by an enemy battalion. Initially, they reported receiving mortar and RPG fire. The 11th Cav’s Air Cav Troop quickly scrambled a pink team to support B Troop. D Company also quickly responded to the fighting, and linked up with B Troop by 0845. As D Company moved into the area, one of the M48s was damaged by a mine. By about 0900 hours, B Troop and D Company were in contact, the Air Cav Troop was supporting with some helicopters, the Squadron’s Howitzer Battery was bombarding the area and Blue Max A R A ships were on station. Soon after the scheduled air strikes came in. But instead of dropping on their previous locations, they used the current contact sites. Also in the air were Medevac helicopters, which arrived at about 0915 hours to rush some badly wounded troopers to medical aid. Some men however, were already dead. By 0929 C Troop had linked up with D/2/7 to the south of the contact where they waited as a reserve force. The artillery, Blue Max and 11th ACR cobras, with the TAC jets continued their support thruout the contact. There was a second dust-off about an hour after the first. As the two armor units pushed forward, they received not only RPGs, but 82mm mortar fire, as well as small arms and 57 recoilless rifle blasts. B Troop drove the enemy back enough to capture the recoilless rifle, by 1032. At 1155 B/1/11 and D/1/11 were at XT405862, while XT405845 was the location of C/1/11 and D/2/7. By 1315 hours the battle had ended with the enemy fleeing to the north and northeast. Four GIs were killed and thirteen wounded. The enemy lost 32 killed. One Sheridan was a combat loss, one M48 was badly damaged, and one M48 was lightly damaged by a 20-pound mine. Our forces captured one 57mm recoilless rifle, two 9mm pistols, one .51mm tripod, one field telephone, two field packs, and documents. After the contact, C Troop and D/2/7 helped sweep thru the area. B Troop’s NDP was at XT381839, with five auto ambushes nearby. C Troop spent the night at XT430853, with one ambush position, at XT434838 and five automatic ambushes. HHT secured Sharon and set out one automatic ambush nearby. D Company Returned to Sharon for the night.
There was no significant action on the following day, but the general plans were similar to those of the previous day. C Troop, with D Company and D/2/7 were to conduct a coordinated assault on the elements of the 95C Regiment. C Troop moved from XT430855 to XT415875 and set up the NDP at XT415853, with six automatic ambushes. D Company went from XT415855 to their objective at XT 410875 and returned to Sharon for the next night. D/2/7 remained with C Troop. B Troop remained nearby at XT381859 and placed an ambush position and three automatic ambushes nearby. The 3/919th Engineers swept 246 from Sharon to XT470820. They found one T46 mine at XT405843, which they removed and destroyed. Later, they returned to Sharon. Headquarters Troop secured them.
For the twelfth, the Engineers swept 246 from Sharon to Rhonda. Headquarters Troop stayed at Sharon during the day to secure it. A VHIH from the Headquarters Troop aviation section was fired upon at 1210 hours while flying near XT3579. The ship was flying at 2500 feets and 80 knots and was not hit. At 0620 hours XT415853, C Troop and D/2/7 received 14 rounds of RPG fire and RPG 7 fire, with small arms from the north and west. About this time a trip flare went off, and an individual was spotted, B Troop, at XT381859 was bombarded with fifteen 82mm mortar rounds fired from the northeast, but there were no casualties. Back at C Troops NDP, seven RG rounds had impacted inside the perimeter, striking five vehicles. C Troop returned the fire, and the Squadron artillery shelled the area. At 0648 hours, First Squadron CP ordered D Company to move from Sharon to reinforce C Troop. Seven minutes later Blue Max also radioed that they were enroute and would arrive within ten minutes. The second Blue Max section arrived a few minutes after the first. D Company arrived and combined with C/1/11 to sweep northwards. At 0823 hours, a C Troop Vehicle in the sweep was damaged by an RPG and one of the crew was killed. D Company had swept thru some of the area when they were fired upon by small arms fire, with one man killed. As the three elements pushed slowly to the north, the Blue Max and air Cavalry Troop Cobras straffed the area to the north and east where C Troop has seen movement. By 0938 hours, the second Medevac mission was completed, having come from Quan Loi and Tay Ninh. Soon after this, they were followed by another for a POW. At 1030, the TAC air strikes were guided in by the FAC. Soon after this the enemy evaded to the northwest, and contact was broken. The contact area had remained quite small. At the end of the fighting, D & C Troops and D/2/7 were at XT415860. B Troop, which had left its NDP at 0922 hours to reinforce the other units, was about 700 meters to the south, at XT415853. The results were as follows: C Troop had 2 dead, four wounded, an M551 and six ACAVs were moderately damaged, all from RPG fire.

At 1400 hours and XT401863, B Troop did discover a large bunker complex. There were twenty-five bunkers, each measuring 5x12 feet, with overhead cover. The bunkers contained two burner ovens, and there were silhouette targets of M113s, surrounded by dirt berms. These latter objects, plus documents found indicated that this area had been used for training. At XT411866, B Troop found 25 more bunkers, each 5x12x4 feet, with no overhead cover. Two of the bunkers were mess halls, with tables and benches in the area. That night B Troop had an ambush position at XT388854, with three automatic ambushes nearby and the NDP at XT375856.

At XT388854 was a 23-pund pressure-detonated mine, which was evacuated to the Squadron Command Post. At 0915 hours and XT378858 was a 25-pounder, and at 1000 hours at XT662842. Both were removed from the road and destroyed. When the party reached Ronda, D Company remained there as a ready reaction force for B & C Troops, and then the tank company returned to Sharon that night. B and C Troops were both to perform a BDA mission and recon the area north of 246. B Troop area was from Ronda to XT395890 to XT410860.While B Troop was on its bomb damage assessment mission, at XT389880 they found a complex of Z-shaped bunkers, measuring 20x10x12, with a foot of overhead cover.

HHT secured the engineers on this sweep, and returned to Sharon that afternoon. The FSB took 10 rounds of AK47 fire during the day, but when they swept the area, they found nothing. The sweep was done by Headquarters Troop. While on VR, the Squadron S3, Major Abrahemson discovered three totally different trail locations that had been used recently by the enemy. At XT382808, three or four men had crossed the trail within 24 hours. At XT397830, five to ten people had passed within two days. The third location, XT400845 had seen five to ten soldiers within 24 hours.
Although there was no major contact, the 15th was a busy day for the First Squadron. At 0006 hours, the radioed that they had emplaced an auto ambush just south of hiway 246 at XT460819. The Regimental S2 had distributed a banner in that location and the Squadron had placed its ambush about 25 meters south of the banner. The First Squadron message to the Second said “Advise units entering our AO tomorrow of this fact. You will be safe if you do not investigate the area near the sign.” By 0540 hours, the Second Squadron had returned a message stating that ambush must be taken out by 0900 hours, because some of the vehicles passing over the road did not have any communications and might accidentally detonated it. By 0830, personnel from Headquarters Troop had disassembled the ambush. C Troop’s automatic ambush at XT402817 went off at 0550 hours. The Troop fired into the area with M551 main guns, mortars, and howitzers from Squadron CP.

14. Intelligence for March: Documents found on dead NVA on 15 March at XT402817 identified the T103 Training Battalion, 9th VC Division, and the C94 Engineer, C95 Combat Reconnaissance, C96 Transportation and C97 Surgical Companies, 7th NVA Division.
On 3 March at XT527831, C-2/8th Cav (OPCON 2/11) made contact while sweeping an automatic ambush site. Artillery and LFT helped kill 10 NVA with only one US wounded. Documents from the bodies identified the Branch 8Transportation and Storage Unit and the Ct 53 Hospital of the 50th Rear Service.
C Troop, 1/11, fought at XT458862 on 5 March. Artillery, aerial-rocket artillery and tactical air strikes left 17 NVA dead with six US wounded. There was no unit identification.
On 10 March at XT405846, B Troop and D Company combined to kill 32 enemy dead, with 4 US killed and 13 wounded. Documents from the bodies identified the Third Battalion, 95C Regiment.
Elements of the 50th Rear Service Guard have been continuously identified along the eastern boundary of the 11th ACR TAOR confirming the unit’s mission of transporting supplies, food, and medical evacuation from Sub Region 1 to the Fishhook. AT 547765, 527832, 509869, 527832, 518707 and 504900, documents have been captured which identified the 50th RSG.
Even if enemy activity remains at a low level, the enemy’s ability to maintain presence in War Zone C will assume importance as Vietnamization and troop withdrawals continue. The enemy must insure his troops are supplied in order to maintain political leverage in these areas.
Thus enemy activity in eastern War Zone C can be viewed as a reaction to the 11th ACR interdiction of the Saigon – Michellin Corridor supply route where the 50th RSG is having difficulty in resupplying Sub-Region 1, particularly the 101st NVA Regiment. The reaction may also be an attempt to counter the armored units in an area so close to NVA Base Areas 353 and 352.
It is expected that both the 95C and 165th NVA Regiments as well as rear service guard and border security units will continue sporadic harassment of the 11th ACR. They will continue reconnaissance to develop alternate supply routes. Offensive operations will probably be limited to economy of force measures. without hard intelligence, enemy intentions cannot be assessed. The mission of the 165th must be known, as well as the 7th NVA Div’s interest in the area.
From 19 to 24 March there were several enemy iniated attacks in the Aos of 1/11 and 3/11. Perhaps these attacks were intended to encourage the 2/11 troops to redeploy to either area. (On Jan.21, 2/11 troops reacted from Bu Dop to Loc Ninh to support a 1/11 contact.) The reason could be that such a plan would open a corridor from Cambodia to the south where the 50th RSG could supply SR1 and SR5 which have been severely hampered by shortages of food, ammunition and personnel. Documents and prisoners have indicated the severity of the problem in these regions. It is apparent that 2/11 has restricted the flow of men and material to the south.

15. Could not read In April.
From 5 April to 11 April there were 18 ground-toair firings, 4 attacks by indirect fire, 11 enemy contacts and 99 mining incidents. The week before there were 5 ground-to-air firings, no attacks by fire, 10 contacts and 51 mining incidents. Analysis of the increased ground-to –air firings was found to be credited to enemy planning. The enemy has issued armor piercing rounds to be used in AK-47’s for firing at helicopters. The increase occurred when the enemy was preparing for the attack on Ft. Defiance. Since many of the firings occurred when the ships were at high altitude, 2500 to 3000’ the enemy may have used them, in part, to divert attention from his other activities. The decrease in mining incidents was the result of two things: one, less Squadron LCC movement, thus lessening the chance for mines, and two, the enemy’s preoccupation with preparing the attack.
The four attacks by fire were in conjunction with the attack on Ft, Defiance. The first attack’s magnitude indicates that it was a pre-ground probe attack. The other three attacks were diversions to allow ground troops and cover disengagement and withdrawal.
One significant shift in enemy patterns: the 50th RSG has begun to move through the area west of Defiance. probably caused by the constant interdiction of the east trails by automatic ambushes. Last week the enemy set off 17 AA’s, while in this week he set off only 8. This drop was caused by F Troop reconning the Mustang Trail. When troops move west of Hazel the effectiveness of the AA trout lines will increase.
On 7 April G/2/11 established a live ambush with AA’s in blocking position. A trip flare went off, and 25 individuals were seen in the kill zone. The NVA fled, leaving 500 lbs of rice, fish, packs, uniforms and medical supplies. It is suspected that the equipment was intended for the 101st Regiment. Since this ambush the enemy has returned to small groups, 4 and 5 men. Overconfidence in the safety of the area and the dire needs of the 101stprobably caused the attempt to move such a large group. The movement was primarily by groups of SR-=1 and 50th RSG, both attempting to get to the 101st south of highway 246 along the Saigon River.
A major shift in the 9th VC Division seems to be in the final stages. The 271st Regiment has deployed to the Angel’s Wing area. The 95C Regt. Is ready to move into base area 354. It has been out of contact since March 12 and has probably had some re-supply and re-fitting. When the 95C Regt. Displaces south of the Dog’s Head to base area 354 the 9th VC Division will be in its “wet season” confirmation. The 271st will probably attempt to intardict LCC’s south of Tay Ninh.
The 7th NVA Division is showing signs of its wet season displacement. The 165th NVA Regt. is in its Fishhook area. The 141st or 209th NVA Regt. will probably displace to the Flat Iron area of base area 352. He other regiments will remain in Base Area 350 and as the weather deteriorates all regiments will attempt to gain foothols in Binh Long Province, trying to intardict CL 13 population centers and RFPF/ARVN camps in the province.
The identification of the Z-22 Artillery Battalion on two occasions from AA’s indicate a shift from its last location in the Bu Dop area on 24 Nov 69 to Eastern Tay Ninh Province. Current indications are that this unit is in direct support of the 165th Regt. targeted against the 2/11. Documents indicate and information from interrogation of LE NGOC CU, a PW from C16 Company, 165th Regt, indicate that Z-22 Arty Bn may have operational control of the indirect fire companies of the 165th regt.
The current mission of K4 and K5 of the 165th NVA Regt is to attack 2/11 FSB and NDP’s with heavy indirect fire followed by ground probes. Currently The Regt. is as follows: K4 495868, K5 578755, K6 573853, with Regt. Hqs. In Cambodia near bridge 8 XT 4895. The C-18 AA Company has been split with platoons sent to each battalion. For the Z-22 Bn see above.
All Bns of the 95C Regt, are operating within or east of BA 354. TheK9 Bn was identified on 13 April at 022669 when B/1/11 engaged 8 NVA evading in a bunker, killing 7 and capturing 1. FSB Kramer received a rocket attack on 15 April from 95C. 95C remains targeted against FSB’s east of BA 354. Current intelligence indicates the 3rd Bn at WT 960737 and 2nd Bn at WT 942742.
Enemy activity for the period 12-18 April consisted of 17 ground-to –air firings, 3 attacks by indirect fire, 5 enemy contacts and 7 mining incidents.
Elements of the 165th Regt. were identified on two occasions. On 22 April the Z4 Bn was named by documents found in a bunker complex at 592773. This area was suspected, because of their move south in early April. This Bn may have attacked the CIDG at Tonle Chan on 20 April. Since then they have avoided contact and activity in that area has decreased, indicating that the Bn is not to be tasked in the near future. The Bn may be inactive while it prepares for Phase 8 of Campaign X. On 19 April, F Troop engaged a small force near its NDP. A PW, Ngo Duc An, stated that he was a member of a recon party along with one man from the Bn recon. They were to recon armor units and stage an attack within 24 hours after the recon was completed. The Z4 Bn attacked FSB BURKETT on 20-21 April. They may have moved north to prepare for Phase C attacks perhaps further south.
The 209th NVA Regt. was confirmed as occupying the AO previously held by 95C Regt. On 18 April documents from a KIA named the C-25 Recon Co. at 454760. Three maps were found, indicating the K8 Bn possibly south of 246 and Bo Tuc. On 23 April at 412791 the Z6 Bn was confirmed. Two namings of the E-3 F-304 Div. in NVA appeared. On 21 April C/1-7 found documents that named group 2142 and E-3 F304. On 25 April following an attempted ambush at 399846, documents were found that indicated that members had previously been a part of E-3 F304. Also on 25 April, B Troop found a letter on a KIA NVA that identified C-9 Co, 209th Regt. In the past the 304th Div. has supplied the 209th, and it seems that they have resupplied them- with possibly the infiltration group 2142. The Regt. appears to have deployed into the KATUM-Bo Tuc area and currently has Z8 Bn forward, south of 246. The rest of the Regt. is north of 246, with the HQs near Cambodia.
On 20 April, at 518730, documents found in bunkers named the 101st and the 50th S.G. The 50th RSG supports the 101st as it begins its early stages of possible movement south. Indicators are that the 101st and 50th RSG are using a route from the Suio Ngo Bed into Minh Thanh rubber Plantations. No indications appeared near Soc Con Trang or Katum-Bo Tuc. On 21 April C Troop found NVA KIA at AA site 538838, men trained in the 101st Regt of the 325 Div, in Group 2156. They were members of New 101st Regt headed south. The documents indicated that they received extensive political training. On 22 April G Troop at 506806 had a AA activate that identified 101st elements. With the documents was a NVA Pfc collar brass of crossed RPG’s. This may indicate that the 7th NVA Div had been trained to fight armor. This may aid reports of 101st OPCON to the 7th NVA Div, and indicate future plans as it moves out of COSVN base area. The fact that the Regt. appears to be infiltrating south in the direction of the Minh Thanh Rubber Plantation would seem to indicate that the 101st Regt will probably conduct operations along QL 13 and be targeted against the 1st ARVN Cav Regt, which works from Lai Khe to An Loc.
