 The Tien Giang Tactical Area

Markey repeated MACV’s criticism of the government’s shoddy treatment of the Self Defense Corps. He likewise advocated a robust information campaign, first to motivate soldiers to fight for their country, and second, to get them to treat their countrymen with respect, for their “conduct with the civilian population, especially during the conduct of operations, leaves much to be desired.”28 Adding to the usual challenges in correcting these entrenched deficiencies was the fact that between November 1963 and March 1964, the 7th Division had gone through five different commanders. The revolving door had to stop and Markey wished that MACV had the power to prevent the Vietnamese from removing officers, particularly when the primary reason for the change was political. 

 During the first half of 1964, the autonomous Tien Giang Tactical Area south of Saigon 

had been one of the most contentious places in South Vietnam. The summer mon

soons brought no relief, as the number of enemy incidents in the third quarter of 1964 

increased by 52 percent over the previous quarter. As was the case with other divi

sions, the 7th Division, which controlled the area, tried to achieve a balance between 

pacification and offensive operations, but the need to react to enemy initiatives often 

disrupted this effort.40

 Using the Cushman concept as a model (see Chapter 6), by July, the division had its 

own pacification cadre trained by division and province personnel. One American and 

six Vietnamese MEDCAP teams actively treated the rural sick. Division senior adviser 

Col. Edward Markey credited the division’s educational efforts in getting tactical units 

to be more sympathetic to the population. By July, the division had completed 106 of 

the 405 New Life hamlets planned for 1964.

 T

 he division relied heavily on artillery to perform its mission. Howitzers covered 

85 percent of the Tien Giang area and helped repulse 218 of 243 attacks in July. During 

that same month, government pieces expended more than 6,000 rounds in harassment 

and interdiction fire that produced 200 known casualties. In one incident, 105-mm. 

howitzers fired fifty rounds based on information provided by a civilian, killing 

twenty-four insurgents. The enemy evacuated about seventy additional casualties 

before troops arrived.41

 U.S. Army Aviation also played a key role. The division typically ran three to 

four “Eagle flights” per week, in which U.S. helicopters ferried Vietnamese soldiers 

of platoon or company strength over the countryside in search of insurgents. The 

modus operandi was for Colonel Markey and the division G–3 to take to the air in a 

command-and-control helicopter. If they saw something suspicious, they would send 

in a helicopter bearing a squad from the division’s reconnaissance company. During a 

typical flight, they would drop five to ten squads to search multiple locations. If contact 

occurred, they could call in the rest of the company, or even the divisional reserve—

 two airborne battalions assigned to Tien Giang because of the area’s heavy fighting. 

T

 he technique was successful, but during one landing, Markey triggered a booby trap 

that injured his leg. He returned to the United States for treatment.42



On 22 June, the 1st and 3d Airborne Battalions were on a search-and-destroy 

operation in support of the 7th Division near Bang Lang, Dinh Tuong Province, 

72 kilometers southwest of Saigon when they ran into the 261st and 514th PLAF 

Battalions. Enemy fire downed four U.S. Army helicopters, including one carrying the 

commander of U.S. Army Support Command, General Joseph Stilwell. The general and 

all the aviators emerged unscathed. Meanwhile, helicopter gunships lent their support 

to the fight, at one point accidently inflicting nine casualties on the South Vietnamese. 

T

 he combat below was intense, with the paratroopers charging the enemy multiple 

times. Hostile fire killed or wounded all nine platoon leaders in the 1st Battalion, but 

the unit never wavered. The enemy retreated at the end of the day. The paratroopers 

lost twenty-nine killed and eighty-nine wounded. Known enemy losses amounted to 

f

 ifty-eight killed, twenty-six fighters captured, and twenty weapons. One adviser called 

the battle a “little classic of a military operation.” The Army awarded a Bronze Star and 

two Silver Stars to three advisers who fought in the action. One of the men who earned 

the Silver Star was Capt. James J. Lindsay, a future general.43

 On 18 July, nearly one hundred U.S. helicopters ferried troops to Cao Lanh, Kien 

Phong Province, 80 kilometers south of Saigon. The massive operation did not achieve 

much, but the enemy shot down a helicopter that was evacuating wounded soldiers.

 more helicopters arrived to rescue them. Troops also deployed to guard the downed 

helicopter and a team of U.S. technicians. The craft flew out on its own power the 

following day.44

 At 0100 on 20 July, the revolutionaries launched a major attack of their own. 

T

 hey massed three battalions—the 261st, 263d, and 514th—and one company each of 

recoilless rifles, machine guns, mortars, and sappers to attack Cai Be district town in 

western Dinh Tuong. About 300 soldiers, drawn from a regimental headquarters and 

local territorials, defended Cai Be. The insurgents penetrated the town and inflicted 

much damage, particularly on the housing of Regional Forces families. They killed 

twelve defenders and forty dependents. Another forty defenders and forty civilians 

suffered injuries. The insurgents withdrew at 0500.45

 T

 he government responded with five battalions backed by armor to pin the enemy 

against the Mekong River, 5 kilometers west of Cai Be. Two battalions saw the most 

action. The 8th Airborne Battalion occupied Cai Be and then continued through sugar 

cane and rice paddies until 1545 when enemy fire hit two of its companies. The lead 

company advanced an additional 90 meters when heavy automatic weapons fire finally 

stopped it. The second company faltered after enemy fire killed its commander and 

radio operator. U.S. Army gunships fired 130 rockets as close as 45 meters in front of 

friendly troops to keep the enemy at bay. The battalion eventually withdrew at 1900. 

Meanwhile, at 1600, insurgent soldiers entrenched along a tree line pinned 

down a company from the 6th Airborne Battalion. After some delay, the 

battalion commander accepted his adviser’s recommendation to attempt a double 

envelopment, but the move was too shallow, and the pincers hit the enemy’s front 

rather than its flanks. At 1830, the battalion launched a frontal assault, assisted 

by two armed U.S. Army Mohawk aircraft and several gunships. Unfortunately, 

the gunships mistakenly hit the 6th Airborne, unnerving the unit, which then 

recoiled into a perimeter for the night. After Vietnamese helicopters refused to 

evacuate the casualties, a U.S. Army medevac helicopter arrived to remove twelve 

wounded soldiers. The senior adviser to the Airborne Brigade, Col. John G. 

Hayes, expressed disappointment at the lack of aggressiveness exhibited by the 

airborne battalions that day. Thirteen Vietnamese paratroopers died and fifty-two 

were wounded, as was one American. The enemy lost forty-six dead and a dozen 

f

 ighters taken prisoner. An adviser speculated that the allies had probably caused 

another hundred casualties. Military Region 2 contended that by attacking Cai 

Be it had made the South Vietnamese fearful of attacks on other district capitals. 

Consequently, observed the command, “They are forced to split up to reinforce the 

posts, and the morale of their troops is more apathetic than before.”46

 T

 he politico-military struggle continued in August. Pacification advanced 

modestly. The number of constructed hamlets rose to 155, MEDCAP teams treated 

20,000 sick civilians, and the division completed 18 civic action projects. Against 

this backdrop, the killing continued. On the tenth, Col. Huynh Van Ton reacted 

to information that a PLAF company was located 15 kilometers west of My Tho by

 sending out four battalions (one airborne, one infantry, and two ranger) and an M113 

troop supported by a platoon of 105-mm. howitzers. The armored carriers and the 

airborne and infantry battalions advanced south from Highway 4 while the rangers 

attacked from east to west from a position 5 kilometers to their south. All units made 

contact, and an airstrike helped to kill forty-two enemy combatants. The insurgents 

evacuated an estimated seventy more casualties. The South Vietnamese lost sixteen 

dead and forty-one wounded.47

 Ten days later, revolutionaries sprang a trap of their own. On 20 August, they 

overran Phu Tuc post in Kien Hoa Province, 10 kilometers northwest of Ben Tre, killing 

seven, wounding fifteen, and capturing the rest of the post’s thirty-six-man garrison. 

T

 he insurgents then burned the post and assaulted a nearby hamlet. These attacks were 

primarily a pretext for goading the South Vietnamese into sending a relief force. The 

government took the bait, sending elements of several battalions, which the insurgents 

declined to engage. Instead, they waited until government troops were departing Phu 

Tuc along a forest road, hitting the column when its guard was down. Caught in the 

ambush were 360 soldiers from the 41st Ranger Battalion and the 3d Battalion, 12th 

Infantry. The fighting lasted for more than an hour, with the 514th PLAF Battalion 

launching repeated bayonet charges heralded by bugles.

 Four Americans participated in the combat. 1st Lt. James M. Coyle was severely 

wounded but nevertheless kept fighting. Capt. Bryan C. Stone found himself firing 

a Browning automatic rifle in four directions as the enemy closed in around him. 

1st Lt. William D. H. Ragin grabbed a machine gun from a dead soldier and fired 

it point-blank at sixty advancing enemy soldiers. Moments before, he had thought 

they were friendly because they were clothed in government uniforms. Assisted by 

Sfc. Tom Ward, Stone, Coyle, and Ragin covered the retreat of the surviving South 

Vietnamese. By the time the battle was over, the insurgents had killed 85 South 

Vietnamese soldiers, wounded 60, and captured 122 weapons, with another 91 

government soldiers missing. All four Americans died in the engagement. General 

Westmoreland attended their memorial service, and the Army posthumously 

awarded them Distinguished Service Crosses.48

 Stung by the calamity, U.S. helicopter gunships attacked insurgents exiting the area 

by boat that night as more troops rushed to the scene. Allied forces failed to contact the 

enemy on the twenty-first, and on the night of 21–22 August, gunships again took to the 

night sky looking for sampans. On the morning of the twenty-second, seven battalions, 

two armored cavalry troops, and naval forces tried to encircle the enemy in Kien Hoa’s 

Ham Long District. The first attempt failed, but Ton quickly redeployed his men by 

boats and U.S. helicopters to catch the elusive foe. In the ensuing battle, 7th Division 

artillery fired 3,222 rounds, and the Vietnamese Air Force flew 10 fighter-bomber 

sorties. When the smoke cleared, the allies had killed ninety-eight PLAF soldiers 

and captured forty-three prisoners and thirty-seven weapons. Agents reported that 

the enemy buried another 200 dead and evacuated 300 wounded. Government losses 

amounted to seventeen killed and forty-five wounded. Nevertheless, IV Corps adviser 

Col. Sammie Homan thought that commanders were becoming cautious because of

 the action on the twentieth and other recent ambuscades. To restore their confidence, 

he pledged to use U.S. Army helicopters to escort all future troop movements.49

 An example of the promised support occurred on 5 September, when five UH–1B 

gunships from the 120th Aviation Company supported a 7th Division operation in 

Dinh Tuong. The entrenched insurgents hit three of the gunships, compelling one 

to return to base. The gunships in turn killed sixty revolutionaries and wounded an 

estimated forty more. Thirty-four enemy soldiers surrendered after the onslaught.50

 September brought new men to the top echelons of the 7th Division. Brig Gen. 

Nguyen Bao Tri became division commander, and MACV appointed Col. Robert A. 

Guenthner to advise him. Guenthner had received the Silver Star and Bronze Star 

medals for bravery at Salerno and Anzio, Italy, during World War II. Before coming 

to Vietnam, he had served as an adviser to the Nationalist Chinese army. Guenthner 

continued Markey’s strong support for civic action, psychological warfare, and the 

Chieu Hoi program. He had great respect for the U.S. Operations Mission personnel 

working in the field. He also emphasized intelligence, most of which came from the 

agent networks run by district, province, and division entities. The chief problem 

with the networks was that information traveled slowly, as the agents, fearful that the 

insurgents would detect them if they used radios, preferred to send reports by courier. 

Information provided by civilians was also useful but tended to be exaggerated in 

Guenthner’s opinion.51

 As had previous commanders and advisers, Tri and Guenthner exploited the in

depth knowledge of Major Binh, who had accumulated extensive files over his seven 

years of service in the division’s G–2 section. This data sometimes allowed Binh to 

predict where the enemy might move next, and Guenthner established a joint planning 

committee to target specific enemy units based on the data.52

 Even if pattern analysis helped find enemy units, the division had little luck 

penetrating the National Liberation Front’s political apparatus. The Front employed 

strict security measures, and because torture and death awaited anyone it discovered to 

be a government agent, few were willing to attempt to penetrate enemy organizations. 

As Americans had found elsewhere, Guenthner discovered that even after the 

government had identified a clandestine Front cadre, “there is not an aggressive 

program designed to eliminate these persons.” When a suspect did fall in to the 

military’s hands, the colonel considered South Vietnamese interrogation procedures 

to be poor and accompanied by  “unnecessary shouting, shoving, hitting, and kicking 

of the captive.”53

Jogging Along

 September brought one other development in addition to the change in command. 

On 5 September, the Joint General Staff abolished the Tien Giang Tactical Area. It 

transferred the 7th Division and four of the five provinces it supervised to IV Corps 

and assigned Long An Province to III Corps. Over the summer months, the division 

and its provinces had managed to bring about 50,000 more people into the most secure 

category of government control, but the allies conceded that the majority of the area’s 

residents, nearly one million people, remained under the domination of the National 

Liberation Front. 

Battles in III Corp

On 22 June, the 1st and 3d Airborne Battalions were on a search-and-destroy 

operation in support of the 7th Division near Bang Lang, Dinh Tuong Province,
