8. (C) INTELLIGENCE:
A. General: Operation ATTLEBORO was initially a 196th Bde operation to the south and west of TAY NINH City. The AO was expanded to include the DAU TIENG area in exploitation of VC logistical bases located in this area and subsequently included all of War Zone C. VC units located in the area included elements of the 9th VC Division (271st, 272d and 273d Regts), 101st NVA Regt, 70th Guard Regt, U8O Arty Regt, COSVN HQ and associated facilities, the 320th LF Bn, & LF Companies, and local guerrilla elements. The area contained large supply/arms/ammo caches, factories, hospitals and base camps of the Rear Services Supply and Transportation sections of Group 82 and 83. It was anticipated that the VC would have the area well fortified against ground and airmobile assaults. The proximity of the Cambodian border, the
rivers into the ara, the well developed roads and trails attested to the fact that the VC were present and had the area well developed as a diversified military complex. There had been no significant ARVN/FWMAF operation in War Zone C since April - May 1966. Agent reports, PW's, CHIEU HOI's, II
reports, Visual Reconnaissance, H?Sa's and USSF reports were utilized to assist in development of the enemy situation. Generally, the intelligence received before and during the operation proved to be useful when properly evaluated and collated.
b. Terrain: The terrain in the area of operations varied from low flat terrain and cultivated fields to scrub brush and forested areas with double and triple canopy. the latter offered excellent concealment and poor
observation. Avenues of approach were generally limited to developed trails and cleared areas. the only key terrain in the area, in the traditional military sense, is NUI BA DEN mountain, the top of which is controlled by USSF with considerable VC activity on the slopes. Obstacles were found in streams, dense forests, inundated areas and paddies. The low land in the northern area was inundated with water, making movement of tracked vehicles and foot troops very difficult.
(1) 14 to 22 Sep: Cloudy in the early morning hours becoming partly cloudy by noon, with almost daily rainfall.
(2) 23 Sep to 4 Oct: the skies were partly cloudy throughout the afternoon rainshowers were present in the area.
(3) 5 to 8 Oct: Conditions remained partly cloudy but occasional afternoon rainshowers were present in the area.
(4) 9 to 14 Oct: Conditions were again partly cloudy with only slight restrictions to visibility in the early morning hours due to fog or haze.
(5) 14 to 18 Oct: Conditions remained partly cloudy, but daily afternoon and evening rainshowers and thundershowers were present.
(6) 19 to 29 Oct: Cloudy conditions with frequent early morning fog and general rain present over the entire area.
(7) 30 Oct to 8 Nov: Conditions were partly cloudy with no restrictions to operations during the period.
(8) 9 to 19 Nov: Sky conditions continued to be partly cloudy, and there were afternoon rainshowers or thunderstorms present in the area.
(9) 20 to 25 Nov: Partly cloudy without restrictions.
NOTE: Early morning helilift operations were restricted by fog or low clouds until mid-morning on the following dates: 14-15 Sep, 27-29 Oct and 13 Nov.
(1) During the initial phase of the operation around TAY NINH City, the VC units expected to be contacted were the C40 Company, 4 other LF Companies, 1 platoon operating near the TAY NINH West airfield, and other local forces and guerrilla elements operating within 15 kilometers of TAY NINH. The units were probably in the area, but due to the influx of a large US unit, they evidently preferred to avoid contact during the initial stages. Only light and sporadic contact was encountered by the 196th during this phase of
(2) The 196th, in October, shifted its operations to the DAU TIENG area to concentrate on neutralizing two supply activities of the Groups 82 and 83 of COSVN Rear Service units. This shift was prompted by the
numerous reports of logistical complexes in this area and the location by the 1st Bde, 25th Inf Div of 279 tons of rice vic XT482423. Documents captured in the area identified Group 83, a COSVN Rear Service Group, and substantiated other reports that the are was a major VC supply activity. Other documents captured by the 1st Bde were VC plans for political activities, directives from higher headquarters concerning tax collection schedules and personality lists of the Finance Section and other infrastructure activities within TAY NINH Province. The fact that all of the food and documents were found on the fringes of the woods without a major sweep into the interior made the area a very lucrative target for future US operations. During the first half of October, VC units in the area, including the 9th VC Division operated in their normal areas of operations with a gradual southerly movement noted towards the end of the month. Because of the southward movement of the VC units, it was anticipated that possibly elements of the 271s and 273d Regts would be contacted in the area. Local guerrillas operating in the area were expected to offer constant harassment to US forces which proved to be an accurate estimate. Between 20 Oct and 3 Nov, the 196th Bde located several large rice/supply caches in vic XT4342 while making only sporadic contact with the enemy. Documents captured on 31 Oct XT440501 during a sweep through the BEN CUI(?) Plantation indicated that the extensive rice and supply caches were maintained by the B 60 Section, Group 82 of COSVN Rear Service Department. On 3 Nov, 196th elements made contact with an unknown size VC force vic XT415536 and XT442518. The VC used SA, hand grenades, rifle grenades, claymore mines and conducted a determined defense of the area indicating a main force element was involved. Documents captured vic XT454534 on 3 November established that the VC unit contacted was the 095 Reconnaissance unit, subordinate to the 9th VC Division. Six documents contained the designation for the 273d Regt. Sporadic contact continued throughout the night of 3-4 November 1966. On 4 November, elements of the 196th Bde were again heavily engaged vic XT417540. Three company size VC assaults were repelled during the day resulting in 40 VC KIA (BC). Documents captured on the battlefield identified elements of the 271st and 273d Regts. Shortly after midnight
on 4 Nov, the 2d Bn, 272d Regt executed a coordinated attack on SOUI CAU OP vic XT453289 using mortars, RR, AW and a variety of bangalore torpedoes and satchel charges in an attempt to breach the defenses of the camp. The attack was repelled and the VC took heavy personnel and equipment losses before withdrawing to the BO LOI Woods leaving over 50 VC KIA (BC) on the battlefield. Also on the morning of 4 November, between 0208-0230, 0540-0550
The VC mortared the 196th Bde base camp vic XT165515. It is believed that the attacks were designed to relieve the pressure on VC units in the DAU TIENG area. On 5 November, vic XT4154 and XT4054 elements of the 196th Bde again made contact with a VC force well fortified in bunkers resulting in 123 VC KIA (BC) and 19 VC (POSS). Frontal assaults involving 80-100 VC each were again used by the VC against US Forces. It is believed that the VC force was composed of elements of the 271st and 273d Regts. After the engagements with the 25th Division on 3-4-5 November, the 1st Inf Div made contact with the VC who were withdrawing. the 1st Inf Div had contact with the VC on several occasions and identified the 1st Bn, 2d Bn, and 3d Bn of the 101st NVA Regt and the 2d Bn, 271st Regt and 273 Regt.
(3) The 25th Division main effort was then directed north to War Zone C. It was anticipated that if heavy contact was made, it would be with main force element. Food, supply, arms and ammo caches were expected to be found as US troops moved into the ara. In order to disrupt operations and harassed the US base camp at TAY NINH, VC mortared the camp on the night of 11 November and the morning of the 12th. A search of the mortar position on 12 November revealed a document that indicated that the C16 Recon Company, subordinate to the 271st Regt could have been responsible for the attack. Contact with the VC was sporadic
until 19 November when contact was made with a VC Platoon vic XT216804 and XT229811 and a VC Company vic XT274956. The company contacted vic XT274956 was the C2 Co, 1st Bn, 70th regt.
(The Security Regt for the COSVN) Documents captured vic XT278908 disclosed the LBN 1751B which is the Signal Bn subordinate to COSVN. Documents captured vic XT229811 indicated the unit contacted was a medical unit subordinate to the 271st Regt with a convalescence center and a rear service section also mentioned.
Documents and capture of two 12.7mm barrels vic XT227813 indicated the presence of an antiaircraft Battalion in the AO. This believed to have been the Z43 AA Bn which had been previously reported. Contact continued to be sporadic through the remainder of the operation with the majority of the VC contacted in squad size or less. The VC reaction anticipated by US forces because of the intrusion into War Zone C did not materialize. It is believed that due to the losses suffered as a result of contacts with the 25th and 1st Divs'.
Main force withdrew to avoid major contact and begin returning and supply activities. Local forces were to continue to harass US forces or monitor our movement in the area. During the operation, it is believed the 2d Bn, 70th Regt operated along route 4 and had full responsibility for the road. the 3d Bn 70th Regt had control and operated on route 22. the VC controlled the road running from vic XT396632 to XT380858 is now believed to be a primary LOC for resupply activities in WAR ZONE C. The 1st Div found the majority of the caches in the area along the controlled road. The route runs both north and south, and appears that the VC utilize BOI LOI Woods, the Saigon River and controlled road to accomplish most of their major transportation of supplies. There are no friendly units to harass the VC in the area. It is believed that major logistical complexes are still located along the road, and that the 25th Division did not locate any major caches in
their area of operations in the heart of War Zone C because the USSF Camps at TRAI BI and SOUI DA are in excellent position from which to harass the VC logistical routes. The VC prefer to have a controlled route through War Zone C from which they can support operations in any direction with relatively no harassment. Indications are that ATTLEBORRO completely disrupted VC plans for a major winter offensive by the 9th VC Div and the 101st NVA Regt. Rice caches (1 ton or over), base camps, supply caches, ammo caches, and contact of estimated platoon size or larger:

On either side of the trail were foxholes and trenches. Twenty-eight piles of laterite were discovered from XT445493 to XT445506.
(6) 3 November. The 196th Inf Bde planned to search for cache areas to the north. In order to do this, they had 3 battalions; 2d Bn, 1st Inf; 4th Bn, 31st Inf; and 1st Bn, 27th Inf (-). (Diagram 1) The plan was to block with the 1st Bn 27th Inf (-) from XT423547 to XT450538, on the general line of provincial route 19. (Diagram 2) The 2d Bn, 1st Inf (-) would attack on AXIS RED from vic of the rice cache area XT4450 to the northwest 1000 meters, then guide on a trail as it goes to the northeast. A coordinating point was established at XT434538. Co A, 2d Bn, 1st Inf was to attack north on AXIS BLUE which was on the west side on LTL 19 from the 50 east west gridline to XT443538. A Co, 4th Bn, 31st Inf would attack on AXIS WHITE which was on the eastside of LTL 19. The 4th Bn, 31st Inf would attack on AXIS PURPLE northeast from the rice cache area until they reached a trail vic XT461507 and would then guide on the trail until reaching a coordinating point at XT450538. The operation kicked off at 0900 hours when 2d Bn, 1st Inf (-) and 4th Bn, 31st Inf (-) attacking along AXIS RED, BLUE WHITE AND PURPLE. At 0922, B Co, 1st Bn, 27th Inf landed at LZ#2 vic XT463529. The LZ was cold. The company moved north for 1200 meters, through elephant grass to vic XT411538. At that time the company commander sent a point forward to discover the trail the company had to guide on. Upon moving 40 meters north into the wood, the point came under small arms and semiautomatic weapons fire. The company in the elephant grass also came under fire from the front, both sides and rear which cut off any escape route. (See Diagram #3 for disposition of the unit.) The company had come upon a fortified position of the Recon Company of the 9th VC Division. Upon coming under fire, the company suffered casualties immediately. By 1210 hours the company had 6 KIA and 6 WIA. One of the casualties was the commanding officer. At 1120 hours, B Co 2d Bn, 1st Inf on AXIS BLUE ran into an enemy position on the 52 east west grid line. The fight lasted a short while and the VC withdrew. The 2d Bn, 1st Inf (-) continued on its mission. By 1230 hours, Co C, 1st Bn, 27th Inf had 10 KIA and 14 WIA. At that time, A Co 1st Bn, 27th Inf
which was at DAU TIENG was committed to reinforce Co C, 1st Bn, 27th Inf. At 1248, the 1st lift of A Co 1st Bn, 27th Inf landed vic XT410534. At 1306, the 2d lift arrived and the company was ordered to attack west of C Co, 1st Bn, 27th Inf and to roll up the VC flank. AT 1330, C Co, 3d Bn, 21st Inf was moved to DAU TIENG and 2d Bn, 1st Inf (-) was alerted to reinforce 1st Bn, 27th Inf. At 1425 the 1st lift of C Co, 3d Bn, 21st Inf landed at LZ#1. At 1505 the 2d lift landed. C Co, 3d Bn, 21st Inf was then ordered to attack east of C Co, 1st Bn, 27th Inf. (See Diagram #4) At 1515 hours A Co, 1st Bn, 27th Inf married up with C Co, 1st Bn, 27th Inf vic XT411537. At 1550 hours, C Co, 3d Bn, 21st Inf married up with 1st Bn, 27th Inf (-). At 1600 hours, 2d Bn, 1st Inf (-) was ordered to reinforce the 1st bn, 27th Inf (-). At 1800 hours, 2d Bn, 1st Inf (-) landed and a
perimeter was formed vic XT410537. (See Diagram #5) Evacuation of The next four pages are very difficult to decipher. The copy is probably from badly exposed microfilm. The left and bottom part of the document were cut off. Much of the transcription on these pages is guess work......
dead and wounded began and lasted into the night. There were VC probes on the perimeter that night. Late that evening the 196th published orders for 4 Nov. (See Diagram #6) The 1st Bn, 27th Inf(-) ?? attack northeast guiding on the same trail that C Co, 1st Bn, 27th Inf ?? supposed to guide on the day before and found a position vic XT4245???? ?? 1st Bn, 27th Inf was to attack west along LTL 19 and link up with 1st Bn, 27th Inf (-). The 2d Bn, 1st Inf (-) was to attack east and establish a position at XT443537. A Co, 2d Bn, 1st Inf would attack west and link up with 2d Bn, 1st Inf (-). The 4th Bn, 31st Inf would attack northeast to a blocking
position vic XT437553. The purpose of the operation was to prevent the 9th VC Division from moving to the southeast and at the same time to consolidate all subordinate commands.
(7) 4 November. AT 0900, the 4th Bn, 31st Inf departed their battalion base vic XT450538 for a blocking position at XT4?9553. They encount-ered no opposition. B Co, 1st Bn, 27th Inf (-) began movement to link up
with 1st Bn, 27th Inf (-). A Co 2d Bn, 1st Inf also began their move west to link up with 2d Bn, 1st Inf. The 1st Bn, 27th Inf (-) did not begin their ?? until their eight kia? had been evacuated. The 2d Bn, 1st Inf (-) began
to move on the east at 1045. At 1140 hrs, the 1st Bn, 27th Inf (-) began moving to the northeast with A Co, 1st Bn, 27th Inf leading the Bn ?CA Ops? ?? 3d Bn, 21st Inf; and C Co, 1st Bn, 27th Inf following that order

The lead element moved approximately 750 meters from the east when all of A Co, 1st Bn, 27th Inf came under ???, automatic weapons and machine gun fire vic XT413541. Co ?, 3d Bn, 21st Inf was ordered to establish a position the the left flank of A Co, 1st Bn, 27th Inf. In doing this, two plts went to the left flank and one plt went to the right flank. The 1st Bn, 27th Inf (-) was still under heavy fire from both their flanks with sniper fire from the rear even though the VC position was ?? (Diagram #7). The CO, 1st Bn, 27th Inf ordered Co D, 1st Bn, 27th Inf to
??? two plts to the left flank of C Co, 3d Bn, 21st Inf and one to the right of the 1st Bn, 27th Inf. By this time the misplaced plt of C Co, 3d Bn, 21st Inf ?? returned to ?? company position. The plt of C Co, 1st Bn, 27th Inf which was to tie in with the right flank of A Co, 1st Bn, 27th Inf was not able to accomplish this because of the heavy fire. The CO of A Co, 1st Bn, 27th Inf which observed this and ordered his right flank plt to turn back and link up with the ?? from C Co, 1st Bn, 27th Inf. (Diagram #8) This was immediately done. Only 30 minutes had elapsed since the beginning of the fire fight. All units of the 1st Bn, 27th Inf were committed. The battalion had no officers in contact with the 196th Bde. However, contact was established through a ?? who relayed the situation to the 196th Inf Bde. At 1246 ? Co, 2d Bn, 27th was alerted for possible movement to reinforce the 1st Bn, 27th Inf. The CO? 2d Bn, 27th Inf requested that he go into action with Co A and Co C, The ? was denied because of the time element. At 1513, the CO, 1st Bn, 27th Inf. ??? to contact ?? 2d Bn 1st Inf ??? and request his assistance 2d Bn 1st immediately started going to the aid of the 1st Bn 27th ??? this was later approved by the Commanding General, 196th Infantry ??? at 1?20, the CO, 1st Bn, 27th Inf was wounded by mortar fragments. The fire in the area continued to be intense, at 1455, ?C Co, 1st Bn, 27th Inf was located at XT424545 and began heading southeast to attempt to aid the battalion. At ??40 C Co, 2d Bn, 27th Inf with the CO, 2d Bn, 27th Inf landing at XT408538. They then moved to the east in an attempt to roll up the VC left
flank. At 1451, the 1st Plt of A Co, 1st Bn, 27th Inf was attacked by an estimated 100 VC who came at the platoon in a line of skirmishers. This was the first of three frontal assaults against A Co, 1st Bn, 27th Inf. C? Co, 1st Bn. 27th Inf and artillery fire repulsed the attack. The artillery was firing from DAU TIENG at close to maximum range at this time. At 14?? C Co, 2d Bn, 27th Inf with a Battalion Command Group departed from an LZ at XT407538. They landed on a cold LZ. The company immediately moved to the east (See Diagram #8) At 1515 hours, the CO, 1st Bn, 27th Inf and CO, 2d Bn, 27th Inf agreed that C Co, 2d Bn, 27th Inf should roll up the left flank of the VC. It took the company 2 hours to reach vic XT411541 due to the dense jungle. At
1?45 hours, a second frontal assault was launched against A Co, 1st Bn, 27th Inf and C Co, 3d Bn, 21st Inf. At 1530 C Co, 2d Bn, 1st Inf had arrived in the vicinity of XT416539 after having traveled through the heavy jungle. C Co, 2d Bn, 1st Inf came under heavy fire from an extension of the fortifications which were pinning down the 1st Bn, 27th Inf (-), C Co, 2d Bn, 1st Inf was about 300 meters from A Co, 1st Bn, 27th Inf at this time. The CO, 1st Bn, 27th Inf ordered B Co, 1st Bn, 27th Inf to fill the gap between the right flank of A Co, 1st
Bn, 27th Inf and the left flank of A Co, 2d Bn, 1st Inf Bn at 1600 hrs. A Co, 2d Bn, 1st Inf had broken contact and was then ordered to swing to the southwest and cover the southeast portion of the perimeter. (See Diagram #9) B Co, 2d Bn, 1st Inf then was moved so that the company was oriented to the east. Also at 1600 hrs A Co, 2d Bn, 27th Inf landed at XT407537. A Co 2d, 27th Inf then moved up and assisted 1st Bn, 27th Inf in securing a PZ and evacuating casualties. At this time the n third frontal assault hit the positions of A Co, 1st Bn 27th Inf and C Co, 3d Bn, 21st Inf. AT 1700 hours it was determined that C Co, 2d Bn, 27th Inf had gone too far to the north and was actually behind the VC positions facing 1st Bn, 27th Inf (-). At 1715 hours C Co, 2d Bn, 27th Inf was under heavy small arms and automatic weapons fire. The CO, C Co. ?d Bn, 27th Inf was immediately killed. The ranking platoon leader took command at 1745 hours. C Co, 2d Bn, 27th Inf Assaulted the position in an attack to overcome the VC. They were unsuccessful. It was determined that the VC position consisted of a series of connected bunkers interconnected by trenches. Extending from the bunkers were cleared fire lanes which extended 100-150 meters from the bunkers. Those lanes had only
the underbrush cleared from them and an soldier would not see them unless he was standing in one. At this time the CO, 2d Bn 27th Inf threw a smoke grenade, and a FAC determined that C Co, 2d Bn, 27th Inf was approximately 100 meters from 1st Bn, 27th Inf (-). At 1730 hours, resupply and medivac began in 1st Bn, 27th Inf (-) area. At 1734 the Co 2d Bn 27th Inf took one squad and attempted to link up with the 1st Bn, 27th Inf. He crossed a fire lane and was killed. Also by this time, the 1st Sgt, a platoon leader, and a platoon Sgt had been killed. The company formed a tight perimeter. C Co. 2d Bn, 27th Inf was not totally isolated
from the remainder of the units on the battlefield. AT 1811 hours C Co, 2d Bn, 1st Inf was ordered by CO, 2st Bn, 27th Inf to attempt a night attack in an attempt to reach C Co. 2d Bn. 27th Inf. C Co, 2d Bn, 1st Inf intended an attack

immediately and were unable to link up with C Co. 2d Bn 27th Inf. At about this ?? time the 4th Bn, 31st Inf; A Co, 2d Bn, 1st Inf and B Co, 2st Bn 27th Inf ?o had earlier been ordered to assist 1st Bn, 27th Inf (-) from the north ?was ordered to withdraw and establish a perimeter vic XT424525. (See Diagram#10) ass night wore on and crippled C Co, 2d Bn, 1st Inf returned, they relieved A Co,? Bn, 27th Inf of responsibility for the LZ as A Co, 2d Bn, 27th Inf was scheduled to make a daylight attempt at rescuing her sister company. C Co, 2d Bn, 27th Inf was ordered not to fire regardless of how many times it was probed. They were probed four times during the night, took casualties but by this tactic the VC were not able to determine exactly where the Company was located.
(8) 5 November. In the early hours, additional DUST OFF ships managed to evacuate the wounded of C Co, 2d Bn, 1st Inf and as the 1st aircraft came in and switched on his landing lights, the VC began a mortar attack. The ?? CO, 1st Bn, 27th Inf called the aircraft and told the pilots either they had to come in blind and land by flashlights or wait until daylight. The pilots of the DUST OFF decided to come in blind and evacuated the wounded of C Co, 2d Bn, 1st Inf by morning. As daylight came, the fire fight continued. At 0745 hrs, A Co,
2d Bn, 27th Inf moved out to the east and then north and then west to relieve C Co, 2d Bn, 27th Inf. (See diagram #11) After moving 30 meters, the company came under heavy automatic weapons and machine gun fire and immediately sustained casualties. A Co, 2d Bn, 27th Inf laid down a base of fire and overran three
bunkers and a trench but they could not breach the VC lines. The company again laid down a base of fire and evacuated their wounded and dead. AT 0830, A Co, 2d Bn, 1st, B Co, 1st Bn, 27th Inf and A Co, 4th Bn, 31st Inf who were in a position in the vicinity of XT424546, attacked southwest in order to assist 1st Bn, 27th Inf(-) and C Co, 2d Bn, 27th Inf. The three companies came along different axis and coordinated their movements between each other. At 1000 hours, the Commanding General, 196th Inf Bde placed these three companies under the control of the CO, 1st Bn, 27th Inf. The companies were navigated by sound and ??le. B Co, 1st Bn, 27th Inf was directed into the northeast corner of 1st Bn, 27th Inf perimeter. A Co, 2d Bn, 1st Inf and C Co, 4th Bn, 31st Inf were directed into C Co, 2d Bn, 27th Inf perimeter. By 1200 hours B Co; 1st Bn, 27th Inf reached
the perimeter, having received only one casualty. Also by 1200 hours, A Co, 2d Bn 1st Inf and C Co, 4th Bn, 31st Inf reached C Co, 2d Bn, 27th Inf. Upon arrival; however, the fighting began again in the location of C Co, 2d Bn, 27th Inf. The ?b?? companies were ordered to move north, west and then south to rejoin the main
force. (Diagram 12) This, the force successfully accomplished. The extraction of C Co, 2d Bn, 27th Inf began immediately and was completed at 1600 hours. At 1610 hours, 1st Bn, 18th Inf from the 1st Inf Div landed and the extraction of 1st Bn, 27th Inf Task Force began. At 1630 hours, C Co, 1st Bn, 27th Inf withdrew. ?Co, 1st Bn, 27th Inf withdrew. B Co, 1st Bn, 27th Inf set up a secondary block ? Co, 2d Bn, 1st Inf followed by C O., 3d Bn, 21st Inf and A Co, 1st Bn, 27th Inf conducted a passage of lines through the block. AT the same time artillery fire was called in to within 25 meters of the withdrawing elements. At 1700 hours the ??direction was complete.

8. Phase IV (10 Nov - 26 Nov). For a detail account of units' actions, see the Brigade and Battalion reports of? Appendix A.
(I) On 7 November, following heavy contact by elements of the 1st Inf Div northeast of SOUI DA, this division was ordered to start operations in the western part of War Zone C. B co, 2d Bde and the 2d Bn, 14th Inf were ordered to move to TAY NINH which they accomplished on 8 Nov 66. On 9 Nov, the Div Fwd OP
along with Hq, Div Arty displaced to TAY NINH. The Div Fwd assumed operational control at 0930 10 Nov. The div mission was to destroy elements of the 9th VC Div in War Zone C. At this time, it was believed the 271st Regt (VC) was located in the woods northeast of BAU CO vic XT3370. An order was issued by the 2d Bde to conduct S&D operations to destroy the 271st Regt with priority to objective MONKEY vic XT3970. Operations would not go further north than the 80 east west grid line. Guidance from COMUS MACV required that one B52 strike per day be planned for by each division. The operation began on 10 Nov. The 2d Bde on
that day moved the 1st Bn (M), 5th Inf and the 2d Bn, 14th Inf to CAU CO (XT276) to establish a fire support base. The 1st Bn, 8th Arty then displaced to BAU CO.A decision was made to open the LOC from SOUI DA to BAU CO in order to save on helicopter support.
(2) On 11 Nov, the II FFORCEV commander attached 2d Bn (M), 22d Inf from the 3rd Bde, 4th Inf Div to the 25th Div (-). The Div was to use the battalion near Go DAU HA in order to protect against a threat from the BOI LOI -HOBO Woods complex (XT5333), the 1st Bn, 27th Inf was released from the 1st Inf Div on 11 Nov and arrived at BAU CO on 11 Nov. A series of operations were conducted by this base (see diagram 11&12). The 2d Bn, 14th Inf conducted operations from 11-14 Nov, east of BAU CO, sending patrols as far as the south edge of MONKEY. The 1st Bn, 27th Inf conducted an airmobile assault on the 12th and established a base to search out an area hit by a B52 strike. (See diagram 13 for B52 strike areas). The 2d Bn, 27th Inf moved to BAU CO on 12 Nov. Also on this same day elements of the 196th Inf Bde (LT)(SEP) were released from 1st Inf Div. The 1st Bn (M), 5th Inf conducted a S&D operation north of BAU CO and established on 12 Nov a base which was later called Fire Support Base #1 in the vicinity XT275790. The 2d Bn (M), 22d Inf established three company bases north of GO DAU HA and BAO DON with the mission of conducting operations south of the BOI LOI Woods. On the morning of 12 Nov, the battalion was given orders to secure the Rt 22 bypass in the vicinity of CAU KHOI Plantation in the vicinity XT3445. The Bn made this move on 15 Nov. On 14 Nov. the battalion mission again changed, this time because of a change of mission for the division. The division's mission changed from a search and destroy mission to reconnaissance in force astride Route 14 to KATUM and be prepared to move north and seize objectives in the vicinity of the Cambodian Border or to move southeast to seize BO DUC. The 2d Bn (M), 22d Inf was attached to the 2d Brigade on 14 Nov. The Brigade therefore had 2 mechanized battalions, 5 infantry battalions and 2 artillery
battalions. The 2d Bn, 1st Inf took over the mission of guarding the Route #22 Bypass and the plantation. At that time the division was directed to construct a Special Forces camp in the vicinity of Fire Support Base #1 prior to the completion of the operation. Though this mission was later rescinded, it did ?????

(Note: Pages of original documents are again readable the preceding four pages were hard to decipher).
Fire Support Base #2 in the vicinity of XT270865 was established by the 1st Bn (M), 5th Inf and the 2d Bn (M), 22d Inf on 15 Nov. Two batteries of artillery were then moved to the area. Local operations were conducted in the vicinity of both Fire Support Bases for several days. The base at BAU CO was closed on 17 Nov 66 and the 2d Bn, 14th Inf moved back to TAY NINH. On 18 Nov, the 1st Bn (M), 5th Inf established a base north of KATUM in the vicinity of XT9627. The battalion conducted operations in the area until the 22d. The 1st Bn, 27th Inf moved from Fire Support Base #1 to Fire Support Base #2 on the 18th. A series of combat assaults were conducted from 20-23 Nov. the 2d Bn, 14th Inf conducted one the 20th in the vicinity of XT204803, where the 2d Bn (M), 22d Inf had a sharp fire fight the day before. They conducted another on the 21st to establish a temporary fire support base to support the Aero-Rifle Platoon, D Troop, 3d Sqdn, 4th Cav which exploited a B52 strike next to the border. The 1st Bn, 27th Inf conducted a combat assault on 21 Nov and another on 23 Nov. The decision was made not to move the 1st Bn (M), 5th Inf southeast to the BO TUC area. Rather, the 2d Bn 27th Inf conducted an air assault into the ara on the 22d. On the 23d, the 1st Bn (M), 5th Inf moved back to Fire Base #1 and then secured Fire Base #0 in the vicinity of XT1977 on 24 Nov with one company. The majority of units moved back to base camp on 24 Nov and the operation terminated on 25 Nov for all except the 1st Bn (M), 5th Inf which conducted a reconnaissance to TRAI BI (XT1170).

b. Signal. The circuits established to support this operation are described in the 125th Signal Bn After Action Report (App 2).
14. CIVIC ACTION AND PSYCHOLOGICAL OPERATIONS.
a. Civic Action did not become a part of operation ATTLEBORRO to a measurable degree. This was due to a lack of civilian populace in the AO, particularly in War Zone C. An element of the 196th Bde did conduct one MEDCAP at BEN RUNG (XT3240), a VC dominated hamlet in the CAU KHOI rubber plantation, treating 207 patients. This battalion was statically deployed in the area of this hamlet for prolonged period on a route security mission. An incident occurred on 19 Nov when a 1st Div tank struck and seriously injured an elderly man. He subsequently passed away and was identified as the 3d ranking bishop of the CAO DAI Temple of TAY NINH. The CG, 196th Bde and his S5 accompanied by the TAY NINH Province Chief
immediately paid their respects to the ranking CAO DAI Bishop expressing their regrets. Solatium was paid and the bishop was most impressed by their expression of concern and sympathy. There was little PSYOP exploit possible during the operation due to a lack of HOI CHANI, and few prisoners were taken. Leaflets and
loudspeaker tapes were planned and utilized by the 196th Bde and by the division PSYOP section in support of the 2d Bde. In future operations, each Bde must plan daily applications of PSYOP activities as a regular support adjunct to their tactical plans. Division PSYOP developed and locally reproduced an outline strip
map which was distributed with CHIEU HOI leaflets and NSC passes prior to operations in the KATUM area (XT3093) in an effort to reach any returnees who might be located in this area. The total leaflets distributed and loudspeaker mission flown follow with general subject themes:
Total - 2,697,000 leaflets

15. (C) COMMANDERS ANALYSIS AND RECOMMENDATIONS:
(1) Artillery firing during the conduct of airmobile operations endangered troop carriers and embarked personnel.
(a) Discussion: Infantry Battalion Artillery Liaison officers aboard C&C aircraft were not able to provide timely control of fires during airmobile lifts. This difficulty is attributed to employment of artillery units from several fire support bases in support of several maneuver units. The artillery LNO in the C&C aircraft controlled only those fires in support of the battalion conducting the airmobile assault.
(b) Recommendations: Artillery Liaison Officer aboard C&C aircraft during the conduct of airmobile operations must be from an echelon that is capable of controlling all artillery fires which have an influence on the execution of the airmobile operation.
(2) Two Aviation Battalion Headquarters are neither required nor desirable for an operation of this scope encountered in Operation Attleboro.
(a) Discussion: The Divisions organic aviation battalion is capable of controlling tactical and logistical support for tactical operations of the magnitude encountered in Operation Attleborro. Augmentation is required in POL dispensing systems and pathfinders. The addition of another aviation battalion headquarters serves to increased to chain of communications and coordination on required to execute a given mission. The addition of a second headquarters creates a structure which becomes unwieldy when tactical lift
requirements and logistical life requirements are intermeshed utilizing the same aviation assets.
(b) Recommendation: That the Division's organic Aviation Battalion be utilized to conduct and control all airmobile activities in sup-port of operations employing tactical forces of the size encountered in operation Attleboro.
(3) Airfield operating personnel must be augmented with operat-ing forward airfield facilities.
(a) Discussion: In addition to operating the forward airfield, forward refueling, and forward rearming areas, the aviation battal-ion was responsible for the normal operation of the Division Base Airfield at Cu Chi. Approximately seventy percent of the aviation battalion airfield operating personnel were required for the sustained operation of the forward facilities at Tay Ninh West Airfield. Only thirty percent of the personnel
remained at the Base Airfield, thereby drastically reducing the operating capability of the airfield.
(b) Recommendation: That the requirement for the personnel and equipment to operate the division forward airfield control tower be placed on USARV on a mission basis. The 125th Air Traffic Control Company has the additional mission of operating forward airfields on a mission request basis. A solution arrived at by the 1st Infantry Division is to use a sup-port battalion for the operation of the facilities in the forward ara.
(4) Separate refueling areas and adequate POL dispensing equipment for CH-47 and UH-1 aircraft are essential to efficiently utilize all available daily operating hours of aircraft lift assets.
(a) Discussion: CH-47 aircraft refueling requires approxi-mately thirty minutes per aircraft utilizing the standard 1200 gallon POL dispensing truck. A ration of on 1200 gallon truck per two operating CH-47's
is required to preclude refueling delays. UH-1 aircraft refueling areas and dispensing systems must be capable of refueling a minimum of ten troop carrier aircraft and two armed helicopters at one time. This is best accomplished through the use of six 100 GPL portable dispensing pumps.
(b) Recommendation: That separate refueling areas be established for CH-47 and UH-1 aircraft on all future operations.
(5) Pathfinder requirements for the control of simultaneous activities involving troop lifts and resupply airmobile light companies and artillery or heavy equipment displacement by CH-47 aircraft exceeds the
capability of the Division's organic pathfinder detachment.
(a) Discussion: The personnel and equipment of the Divis-ion's organic pathfinder detachment will permit simultaneous operation in three areas at one time. During Operation Attleboro, pathfinders were frequently required to operate in six areas: Three locations working CH-47 loading or unloading, on UH-1D resupply area, one troop pickup zone and one staging area for reaction forces.
(b) Recommendation: The Division's pathfinder detachment be augmented with a detachment of pathfinders from the unit providing CH-47support.
(6) Aviation requirements for tactical operations and logistical support must be considered simultaneously.
(a) Discussion: Aviation requirements constantly exceeded aviation assets for a given day. It is a must that the unit commander be appraised of aviation assets and consider the requirements for tactical
operations and logistical support simultaneously. The commander must consider the effect of each of these areas upon the other and how he can best accom-plish the mission.
(b) Recommendation: That the unit logistical representative and the aviation liaison officer be brought into the tactical planning as early as possible. This will enable complete plans to be formulated and
presented to the commander for a decision only after all aspects of the oper-ation have been considered.
(7) Requirements for UH-1D command and control aircraft deplete the aviation airlift capability.
(a) Discussion: All requirements for C&C aircraft must be taken from available total lift assets. This reduces the capability of the aviation unit to perform its mission of troop lift or aerial resupply. During Operation Attleboro, four UH-1D aircraft were utilized for C&C by the brigade. Under this concept, and assuming a two brigade operation, the assets of one lift company will be required to support C&C requirements.
1. That the OH-23 capability of the Brigade be used to provide C&C aircraft for ground commanders not engaged in airmobile operations.
2. Each brigade be furnished one UH-1D for C&C to augment assigned OH-23s.
(8) Planning of aviation support must consider the effects of adverse weather and darkness.
(a) Discussion: It is desirable to complete all aviation operations during daylight hours. Night operations near the border and over undefined terrain are hazardous. Adverse weather, i.e. early morning
fog and late afternoon thundershowers, must always be considered as possibility. The effect of these limitations on the mission must be considered by the commander.
(b) Recommendation: That emphasis and consideration be placed on the possibility of adverse weather and darkness when planning an operation. Alternate courses of action should be established.
(9) The determination of overall aviation requirements to support a given operation must consider the rotation of units for maintenance down time.
(a) Discussion: Neither the Division nor supporting aviation companies possesses the capability to displace adequate OL and DS maintenance support to forward locations to sustain the high flying hour demands which were imposed during Operation Attleboro.
(b) Recommendation: Provisions must be made to satellite aviation units on a maintenance facility near the base of deployment for a portion of the OL and all of their DS maintenance or have sufficient
latitude in aviation assets available versus demands so as to permit rotation of units, or portions thereof, to have? station for maintenance.
b. Tactical Operations.
(1) No difficulties were encountered during airmobile operations. This is attributed to the extensive airmobile experience of the units of the 2nd Brigade to include the planning, coordination and execution of combat assaults.
(2) Time factors for the airmobile deployment of artillery units must consider the airmobile experience level of these units.
(a) Discussion: The ability of an artillery unit is to meet average, expected airmobile deployment times is directly proportional to the airmobile training and experience of that unit. Attempts to move such
units by airmobile manes during the rapid pace of combat operations can have a serious impact on the entire ground tactical plan if this factor is not considered and appropriate allowances made.
(b) Recommendations: That artillery units without previous airmobile experience be employed where time factors are not critical, and where feasible, assistance be provided by personnel from experienced units.
(3) Three CH-47 aircraft are normally adequate for the rapid displacement of a 105mm Artillery Battery for one-way distances up to 30 Kilometers. An increase in aircraft above this number offers no increase
in expediting the displacement.
(a) Discussion: The determining factor in short distance displacement of artillery units is the speed with which a unit can rig its equipment for movement. The allocation of lift aircraft above that level which the unit can handle, only results in inefficient use of aircraft.
(b) Recommendation: That extreme care be utilized in determining and scheduling aircraft for heavy lift requirements. The CH-47 Liaison officer is best able to assist a unit in determining the maximum
number of aircraft which a unit can efficiently utilize for a rapid move.
c. Aerial Resupply.
(1) An adequate resupply staging area, properly organized and controlled is essential.
(a) Discussion: UH-1D aerial resupply was hampered intiially by lack of adequate resupply staging area. This was later remedied and positive control and coordination permitted efficient movement of sup-
plies to the units in the field.
(b) Recommendation: Prior to an operation detailed planning must be directed toward establishing the resupply staging areas.
(2) Aviation support of the magnitude required during Operation Attleboro is dependent on early anticipation of the ground unit's requirements and timely passage of information to supporting aviation battalion. Liaison Officers from the aviation battalion and CH-47 unit, located in the Brigade forward command post were found to be indispensable.
(a) Discussion: Upon receipt of the cumulative daily sortie requests, the Brigade S-3, Brigade Aviation Officer and the Aviation Liaison Officers considered the validity of the request, established prior-ities and computed the aircraft requirements for the following day.
(b) Recommendation: That XXXXXX liaison officers be utilized on all future operations of this magnitude.
(3) Unit equipment and supply displacement by airmobile means must be controlled by a representative of the highest headquarters being displaced.
(a) Discussion: A single representative vested with the authority to act in accordance with the ground commanders desires and supported with adequate communications must be present to direct pathfinder personnel during the displacement of a unit's equipment and supplies. In the absence of such a representative of the ground commander, with an adequate communi-cations capability, pathfinder personnel are left without proper guidance should a situation arise which necessitates a change in priority or sequence of events.
(b) Recommendation: That a staff representative of the headquarters being displaced, with necessary communications equipment remain at the displacement site to lend guidance to pathfinder personnel during the conduct of the displacement.
(4) A central agency is necessary to establish resupply requir-ments and priority of movement.
(a) Discussion: The Brigade designated an individual who received and consolidated the logistical requirements for all of the maneuver and fire support elements. He coordinated logistical requirements in view
of tactical requirements and priorities established for aerial resupply. Each battalion further evaluated and established priorities within their assigned block of sorties.
(b) Recommendation: That the Brigade designate an individual to function as a center agency for consolidating resupply requirements and establishing the priority of movement of supplies for all units of the
.............................xerox copy truncated.......................
(5) Accurate forecasting of logistical requirements by supported units is essential.
(a) Discussion: For routine operations, it is essential that daily logistical requirements forecast be accurate and expressed in terms of sorties. In general, the following sortie requirements were average
for this operation:
DAILY RESUPPLY SORTIES
UH-1D SORTIES CH-47 SORTIES
Bde Hq 4-5 None
Inf Bn 15-18 None
Mech Bn 22-28 2 (POL) (20 Barrels per
Arty Btry None 5 (4 ammo, 1 water trailer)
DAILY CARGO REQUISITION SORTIES
UH-1D SORTIES CH-47 SORTIES
Bde Hq 1 None
Inf Bn 5-7 None
Mech Bn 10-12 1 (Empty POL barrels)
Arty Btry None 1
CARGO SORTIES REQUIRED TO REPOSITION UNITS
Bn Hq 8
Inf Bn 1
Arty Bn 13-19
(b) Recommendation: That standard initial supply sorties be established for units based on unit tactical employment. that Unit S-4's establish typical daily aerial resupply requirements for each
individual unit to eliminate the accumulation of supplies in the forward location.
(6) A daily meeting of aviation and logistical representatives to review all requirements is essential.
(a) Discussion: Throughout the operation, the daily meeting (3100 hrs) of the aviation and logistical representatives was most beneficial. This meeting permitted a discussion of the day's activities,
evaluation and establishment of the coming days requirements, and the resolution of any problem or difficulties which may have arisen during the current day's operations.
(b) Recommendation: That this meeting be made a matter of regular practice.
(7) It is desireable that moving units establish a night base early enough to receive resupply during daylight hours. The area chosen should be large enough for multi-aircraft resupply.
(a) Discussion: On several occasions units failed to establish a night base in sufficient time to receive resupply during daylight. Adverse weather combined with darkness could have prevented the
unit's receiving critical supplies on several occasions.
(b) Recommendation: The moving units attempt to establish a resupply base in sufficient time to receive resupply during daylight hours. That this base be capable of accommodating five aircraft
simultaneously whenever the tactical situation and terrain permits.
(8) Aerial resupply of artillery ammunition can be greatly expedited by prepacked loads.
(a) Discussion: The packing of artillery ammunition for aerial delivery is quite time consuming. The prepacking of loads during period of very light requirements would preclude an interruption in flow
during periods of heavy requirements.
(b) Recommendation: That artillery ammunition be prepacked and rigged for aircraft sling loads to meet normal resupply and emergency resupply requirements.

a. 1 November, Battery A, 1st Battalion, 8th Artillery became the first element of the command to become engaged in Operation Attleborro. Initially an alert was received to move one 105mm howitzer battery to Tay
Ninh at 1045 hrs. At 1445 hrs the requirement was changed to move the battery to DAU TIENG by air movement. The movement to Dau Tieng was initiated at 1400 hrs and the battery closed vicinity XT492473 at 2200 hrs having utilized 17 CH-47 sorties. The battery was assigned the mission of reinforcing the 3d Battalion, 82d Artillery.
b. 2 November: Battery A, 1st Battalion, 8th Artillery continued its mission of reinforcing the 3d Battalion, 82d Artillery at Dau Tieng. In order to provide medium artillery fire, Battery C (-), 3d Battalion, 13th Artillery displaced from vicinity Go Dau Ha to vicinity Truong Mit (XT398394) closing at 1130 hours and was assigned the mission of GS; reinforce 3d Battalion 82d Artillery.
c. 3 November: The build up of artillery support continued as a Platoon of Battery B, 3d Battalion, 13th Artillery (attached to 3d
Battalion, 82d Artillery) was moved to vicinity Soui Da (XT349579). Battery A, 1st Battalion, 8th Artillery and Battery C(-), 3d Battalion, 13th Artillery remained in place and continued their mission. Enemy activity indicated substantial enemy strength and resulted in three friendly casualties(1 KIA and
2 WIA) in the 1st Battalion, 8th Artillery.
d. 4 November: Battery A, 1st Battalion, 8th Artillery was attached to the 3d Battalion, 82d Artillery effective 0001 hours. The battery fired in support of both the 1st and 2d Battalions, 27th Infantry. The 1st Battalion, 27th
Infantry became heavily engaged at 1200 hours and was pinned down by heavy automatic weapons fire. The enemy attacked Company A, 1st Battalion, 27th Infantry using human wave assaults, but was repulsed with the aid of fires from Battery A. The enemy attacked again at 1800 and was again repulsed with the aid of Battery
fires. On 5 November surveillance of the area by an infantry element credited Battery A for 25 VC KIA (body count) and 150 VC KIA (possible). The positioning of artillery to support the operation continued with a platoon of Battery B, 3d Battalion, 13th Artillery (attached to 3d Battalion, 82d Artillery) moving to Soui
Da (XT349579) joining the platoon already there. In addition, Battery A, 2d Battalion, 13th Artillery displaced from Cu Chi Base Camp to Tay Ninh Base Camp closing at 2130 hours and was attached to the 3d Battalion, 82d Artillery. Battery C (-), 3d Battalion, 13th Artillery displaced from vicinity Truong Mit to vicinity Go Dau Ha (XT414239) where it remained for the rest of the operation in support of convoys traversing Highway #1 and #22 contributing indirectly to the success of operation Attleborro.
e. 5 November: Battery A, 1st Battalion, 8th Artillery remained at Dau Tieng and along with other elements of the 196th Light Infantry Division. A Command group from the 1st Battalion, 8th Artillery moved from Cu Chi to vicinity Soui Da (XT349579) by CH-47 closing at 0855 hours and assumed control of Battery B,3d Battalion, 13th Artillery. Battery A, 2d Battalion, 13th Artillery displaced from Tay Ninh to Soui Da and was attached to the 1st Battalion, 8th Artillery closing at 1000 hours. The platoon of Battery D, 3d Battalion, 13th Artillery
which was attached to the 2d Battalion, 32d Artillery and positioned at Tay Ninh with concurrences of II Field Force Viet Nam Artillery was directed to move to Soui Da and to become attached to Battery B, 3d Battalion, 13th Artillery. Maintenance difficulties precluded 1 howitzer from moving, however, the platoon less the 1 howitzer displaced to Soui Da closing at 1815 hours and was attached as stated. The second howitzer was repaired with a part airlifted from Cu Chi to Tay Ninh the night of 5-6 November and displaced to Soui Da closing at 061715 hours. At 2400 hours the command group relinquished control of the two batteries which were then placed under control of the 1st Infantry Division.
f. 6 November: At 0001 elements previously under the control of the command group, 1st Battalion, 8th Artillery were attached to the 1st Infantry Division. The command group returned to Tay Ninh closing at 1235 hours. At this point all elements of the command that were supporting Operation ATTLEBORRO were either attached to or under the operational control of the 1st Infantry Division.
g. 7 November: The control group from the 1st Battalion, 8th Artillery displaced from Tay Ninh to Cu Chi by ground convoy closing at 1828 hours.
h. 8 November: At 1200 hours information was received that tactical CP of the 2d Brigade, 25th Infantry Division would move to Tay Ninh immediately. 1st Battalion, 8th Artillery (-) was attached to the 2d Brigade Task Force as of 1200 hours and was to move with the brigade. At 1515 hours the 1st Battalion, 8th Artillery departed Cu Chi for Tay Ninh alerted to move a forward command post to Tay Ninh and the 3d Battalion, 13th Artillery (-) to Soui Da on 9 November.
i. 9 November: The 25th Infantry Division Artillery forward CP displaced from Cu Chi to Tay Ninh Base Camp and established a forward tactical CP vicinity XT165520 closing at 1200 hours. The 3d Battalion, 13th Artillery(-) displaced from Cu Chi to Soui Da (XT343577) closing at 1400 hours and assumed control of its organic units already there. At that time the 3d Battalion, 13th Artillery (-) was comprised of elements of Headquarters, Headquarters & Service Battery, Battery A (-), Battery B (-) and a Platoon of Battery D. The
battalion was placed under the operational control of the 1st Infantry Division. Battery A, 2d Battalion, 13th Artillery was released from control of the 1st Infantry Division and displaced to Tay Ninh Base Camp closing at 1630 hours where it was attached to the 1st Battalion, 8th Artillery and prepared for air move-
j. 10 November: At 0500 hours the 3d Battalion, 13th Artillery reverted to control of the 25th Infantry Division and was assigned the mission on GS, reinforce 1st Battalion 8th Artillery. A Battalion command group and Battery B 1st Battalion, 8th Artillery moved by air to vicinity Bau Tam (XT276685) using 29 CH-47 sorties closing at 1810 hours. BATTERY A, 3d Battalion, 82d Artillery was released from control to the 1st Division and returned to Tay Ninh Base Camp closing at 1840 hours.
k. 11 November: Battery A, 2d Battalion, 13th Artillery and Battery D,1st Battalion, 8th Artillery displaced from Tay Ninh to vicinity Bau Tam (XT276685) by utilizing 41 CH-47 sorties. The forward CP of the 3d Battalion, 82d Artillery returned to Tay Ninh completing the active participation of that battalion in Operation ATTLEBORO. The enemy attacked the Tay Ninh Base Camp with rifle grenades at 2110 hours. As a result of the reaction the attack Headquarters, Headquarters Battery, 25th Infantry Division Artillery sustained 1 KIA when a defective US Air Force flare struck an enlisted man from the aviation section on the head.
l. 12 November: Battery A, 1st Battalion, 8th Artillery was released from attachment to the 1st Infantry Division and moved by air to vicinity Trai Bi (XT119692) utilizing 11 CH-47 sorties. On sortie resulted in a howitzer being dropped some 5 Kilometers from its destination.

12. ADMINISTRATIVE MATTERS.
a. Maintenance: No abnormal mechanical failures were noted during the operation. Preventative maintenance was performed on all equipment during the operation.
b. Transportation: During Operation ATTLEBORO extensive use of aircraft was utilized for both movement and resupply. Between 1 November and 25 November 1966 some 462 CH-47 sorties were utilized and
the UH-1D flew an average of 5:30 hours each day re-supplying forward units and transporting unit and staff personnel. During the operation, support was both timely and well coordinated; often on short notice. The most efficient use of helicopter slings that are available deserve more study. On several occasions shortage of slings or components became critical to the operation. Prompt return of sling equipment to the resupply point must be emphasized. Battery personnel must be well trained in airmobile operations since Pathfinders often have little or no time to check loads.
c. Communications: The wide spread deployment of subordinate organizations made communications difficult. The use of retransmission facilities on Nui Ba Den, facilitated radio communications with subordinate and adjacent headquarters. VHF facilities afforded excellent communications and are considered mandatory for the accomplishment of the mission.
d. During the operation the Division Artillery continued its program of command inspections of subordinate organizations.
13. SPECIAL EQUIPMENT AND TECHNIQUES: A 200 meter height of burst with Shell WP fuze time was effective as the first round in adjustment for a ground observer in dense vegetation. It also proved to be effective in providing navigational marking rounds for maneuvering ground units as well as marking the limits of an axis of advance for a mechanized battalion.
14. COMMANDER'S ANALYSIS: The major portion of Operation ATTLEBORO supported by the Division Artillery was a reconnaissance in force North into War Zone C by a reinforced brigade. Artillery support for the operation involved positioning batteries within fire bases secured by infantry battalions, and as the operation progressed, establishing new fire bases within artillery range of existing fire bases. Medium artilery was used in the mutually supporting fire bases as far into War Zone C as the roads permitted. However, most of the operation was supported by direct support 105mm howitzer batteries, which were employed in two
battery fire bases with an artillery control headquarters. During the operation, an extensive H&I program was developed. Intelligence derived from forward observer reports, visual reconnaissance flights, long range
patrol reports, agent reports and other reconnaissance means were used is a basis for the program. Indications are that the H&I program was highly effective and as the operation progressed it was further intens-
