General Nguyễn Văn Hiếu (June 23, 1929, Tientsin - April 8, 1975, Bien Hoa) was a general in the South Vietnamese army. There is a book about him entitled General Hieu, ARVN: A Hidden Military Gem (2000) by Tin Tin Nguyen and Raymond R. Battreall. As a youngster he lived in Shanghai. He later immigrated with his ethnic Vietnamese parents to Saigon, Vietnam, when the Chinese Communists took over China in 1949.[1]
He attended Aurore University in Shanghai, China.
In 1950, he attended the Vietnamese Military Academy and graduated second in his class in 1951.
In 1963, he graduated from Command and General Staff College, at Fort Leavenworth, Kansas.
His assignments included G3/Joint General Staff,G3/1st Corps, Chief of Staff of 1st Division, Chief of Staff of I Corps, Chief of Staff of II Corps, Commander of 22nd Division, Chief of Staff of II Corps, Commander of 5th Division, Deputy Commander of I Corps, Minister of Anti-Corruption under Vice-President Tran Van Huong, Deputy Commander of III Corps, Commander of Forward HQ III Corps, and MG Deputy Commander of III Corps.
He was presumably assassinated by Lieutenant General Nguyễn Văn Toàn's clique, Commander of III Corps, on April 8, 1975 at III Corps Headquarters, Bien Hoa and on April 10, 1975, he was posthumously promoted to Lieutenant General.

Colonel Hieu, II Corps Chief of Staff, designed and executed Operation Quyet Thang (Sure Win) 202[2] aiming directly at the impenetrable VC stronghold at Đỗ Xá, embedded deeply in the Annamite Mountains, at the junction of three provinces of Kontum, Quang Ngai and Quang Tin, from April 27 to May 27 of 1964.
Participating in the operation were units of 50th Regiment of 25th Division under the command of Major Phan Trong Trinh, four Ranger battalions under the command of Major Son Thuong and one Airborne battalion under the command of Captain Ngo Quang Truong.
Troops were ferried to two landing zones by three helicopters squadrons: USMC HMM-364 Squadron, 117th and 119th squadron of US Army 52nd Aviation Battalion.
The VC attacked fiercely the helicopters at the landing zones during the two first days, and then vanished into the mountains, avoiding contacts with the invading troops. Operation Do Xa achieved the following results: a communication network of the Viet Cong command composed of five stations was destroyed, one of which was used to communicate with North Viet Nam, and the other four to link with provincial Viet Cong units; the enemy lost 62 killed, 17 captured, two 52 caliber machine guns, one 30 caliber machine gun, 69 individual weapons, and a large quantity of mines and grenades, engineer equipment, explosives, medicine, and documents; in addition, 185 structures, 17 tons of food and 292 acres (1.18 km2) of crops were destroyed.
In 1965, the Communists attacked all over the Highlands belonging to II Military Region. Early July 1965, three NVA regiments (for sure the 32nd, and perhaps the 33rd) isolated completely the Highlands. ARVN units could not use National Route 1, 11, 14, 19 and 21, and all resupplies to the Highlands had to be performed by air.
On July 8, 1965, General Vinh Loc entrusted Colonel Hieu, II Corps Chief of Staff, the design and execution of a plan to reopen National Route 19.[3]
Contrary to the general practice of a road-clearing operation which consists in concentrating necessary troops to destroy in gradual steps the ambushes set up by the enemy along the highway, Colonel Hiếu intended to interdict the enemy to set up ambushed locations in resorting to diversionary tactic. From D-6 to D+2, he ordered the 22nd Division and the 3rd Armored Squadron to attack from Qui Nhon down to Tuy Hoa along National Route 1; the 2nd Airborne Task Force together with Regional Forces and Civilian Irregulars Defense Group Forces to retake Le Thanh District; to VNMC Alpha Task Force and the 42nd Regiment to attack from Pleiku up north to Dak Sut on National route 14; and to the 20th Engineer Group to attack from Phu Bon to Tuy Hoa to repair Interprovincial Route 7.
After sowing confusion among the enemy troops with the above-mentioned simultaneous big operations, Colonel Hiếu "press the Viet Cong from three directions with movements launched from Pleiku and Qui Nhon and a vertical envelopment from north of An Khe. These maneuvers were executed by a task force of the Pleiku sector departing from Pleiku, two task forces of the 22d Infantry Division departing from Qui Nhon, and a task force of two airborne battalions heliborne into northern An Khe and attacking south with Task Force Alpha of the marines brigade conducting the linkup," and "position strong reserves composed of three battalions (one ranger, one marine, and one airborne) and two armored troops at tactical points: Pleiku, Soui Doi, An Khe, and Mang Pass." All these actions resulted in the free flow of cargo convoys during 5 days from D+3 to D+7, "allowing an initial buildup of 5,365 tons of supplies in Pleiku." Afterwards, operational units withdrew to their camps during D+8 and D+9.
As a result of Operation Than Phong, "the convoys transfused new life into the Highlands. Along with an immediate drop of 25 to 30 percent in the price of food and commodities, the population regained their feelings of security, confidence, and hope. School-boys in Pleiku voluntarily helped the troops in unloading the cargoes, and people who had started to evacuate now returned to their homesteads."
After the unsuccessful attempt to overcome the Special Force camp of Duc Co in August 1965, General Vo Nguyen Giap launched the Winter Spring Campaign aiming at slicing South Vietnam into two pieces, from Pleiku in the Highlands to Qui Nhon in the coastal regions. The plan of General Chu Huy Man, VC Field Commander was as following:[4]
In order to counter General Chu Huy Man’s clever moves, Colonel Hieu, II Corps Chief of Staff consulted with US 1st Cavalry Division and came up with the following plan:
This plan neutralized the 66th Regiment NVA, which remained inactive in Chu Prong area, destroyed the 32rd Regiment NVA at the ambush site, and the 32nd Regiment NVA had abandoned the siege of camp Pleime and withdrew dejected into the surrounding jungles.
42nd Regiment of 22nd Division, reinforced by 3rd Airborne Task Force establishing a blockage position on the mountain side, joined force with the armored squadron of M113s in sweeping the enemy from National Route 1 into the mountains at Phù Cũ Pass in Bình Định province. Infantrymen in front line formation followed M113 armored vehicles launched fierce assaults, after a salvo of artillery firing. Airborne Task Force Commander, Lieutenant Colonel Nguyen Khoa Nam observing the battle from the mountainside with binocular uttered his admiration, “Colonel Hiếu conducts his troops like a seasoned “armor officer”, and combatants of 22nd Division fought as elegantly as our paratroopers.”
In February 1967, Colonel Hiếu launched Operation Đại Bàng 800.[5] For three days prior to Vietnamese operation, units of US 1st Cavalry Division were unsuccessful in discovering the enemy in their operational areas. Instead of searching for the enemy, Colonel Hiếu was smarter in resorting to luring the enemy, by dispatching a reduced regiment to set up an over-night camp in the region of Phu My, knowing for certain that enemy spies inserted among the indigenous farmers would report the status of the operational troops. Meanwhile, Colonel Hiếu positioned a motorized infantry battalion and an armored unit 10 kilometers away, out of enemies screen radar. Thinking they had an easy target, the enemy attacked the camp with a regiment belonging to 3rd Division NVA at 2:00 am. Alerted by the regiment’s commander, Colonel Hiếu sent in the reserved forces to cut the retreat route of the enemy and to join force with the defenders in an anvil-hammer tactic to destroy them. After a three-hour fierce battle, the enemy broke up contact with more than 300 dead and numerous weapons scattered all over the battleground.

In the end of 1970, General Hiếu planned to lure the enemy with a regiment placed in Snoul deep in Cambodian territory, north of Loc Ninh on National Route 13. The Communists had 3 Divisions (5th, 7th and 9th) operating in that area. III Corps was ready to commit all of its 3 Division (5th, 18th and 25th) in case the Communists dared to engage one, two or all three divisions into the battlefield. Unfortunately, General Tri died unexpectedly in a helicopter accident in the end of February 1971, and General Minh, who replaced General Tri, did not want to follow through with the luring plan, when 8th Task Force was succeeding in attracting the enemy who gathered two Divisions (5th and 7th) around Snoul. The beleaguered troops of 8th Task Force, when neither rescue column nor B-52 bombers were in sight, were about to raise the white flag to surrender to the enemy. However, General Hiếu executed in time his withdrawal plan to bring back his troops to Loc Ninh. The troop’s withdrawal was executed in three phases:[8]
In 1974, as Deputy Commander of Operations/III Corps, assistant to General Pham Quoc Thuan, General Hiếu applied Blitzkrieg (lightning war) tactic to alleviate the pressure exerted by 5th Division NVA originating from Svay Rieng Province in the Parrot’s Beak area inside Kampuchea territory aiming at base camp Duc Hue. Firstly, General Hiếu employed twenty mobile battalions to surround the Parrot’s Beak area.[9] Secondly, on April 27, he launched 49th Infantry Regiment and 7th Ranger Group through the swamp lands around Duc Hue toward the Kampuchean border, and had VNAF airplanes attack positions of 5th Division NVA units. In the meantime, he relied on two Regional Force battalions belonging to IV Corps to move from Moc Hoa up north to establish blocking positions on the southwestern edge of the 5th Division NVA’s logistical base and assembly area.
On April 28, General Hiếu launched eleven battalions into the battleground to conduct preliminary operation in preparation of the main offensive.
In the morning of April 29, three armored squadrons of the III Corps Assault Task Force rushed across the Kampuchean border from west Go Dau Ha, aiming directly at 5th Division NVA HQ. Meanwhile, a task force composing of infantry and armor of IV Corps, originating from Moc Hoa, maneuvered across the Kampuchean border into Elephant’s Foot area to threaten the retreat of 275th Regiment NVA. The three armored squadrons continued their three-pronged advance 16 kilometers deep into the Kampuchean territory before they veered south toward Hau Nghia Province, and helicopters debarked troops unexpectedly on enemy positions, while other ARVN units conducted rapid operations into the region between Duc Hue and Go Dau Ha.
On May 10, when the last ARVN units returned to their base camp, enemy communications and supplies networks were seriously disrupted. The Communists suffered 1,200 deads, 65 prisoners, and tons of weapons captured; while, due to speed, secrecy and coordination factors of a multi-faced operation, the ARVN only suffered less than 100 casualties.
Vice President Tran Van Huong appointed General Hiếu anticorruption czar on February 10, 1972. He occupied this position until October 1973. At that time corruption was rampant among the ARVN leadership, in the army, the administration, the police, the power authority, Air Vietnam, customs, etc.…General Hiếu chose to attack first the Military Pension Fund. After a five-month investigation, he presented his findings in detail on the national television on July 14, 1972.[10] As results, the Defense Minister, General Nguyen Van Vy and seven colonels were ousted and the Military Pension Fund disbanded.
However, General Hiếu was not allowed to move on to other corruption targets. President Thieu limited his investigation power to the level of chief of district and prior presidential approval was necessary to commence an investigation at the level of chief of province. These limitations disappointed General Hiếu who sought to return to the military and declared, Either we correct our faults or the Communists will correct them for us.
In the evening of April 8, 1975, news came out of III Corps headquarters in Bien Hoa that General Hiếu was dead in his office. General Nguyen Van Toan, III Corps Commander, was immediately suspected since he had the reputation of being corrupt, while General Hiếu was very clean, and furthermore, had held the position of anticorruption czar under Vice President Tran Van Huong.
The next day, after attending the military press conference, UPI correspondent sent out the following dispatch:[11]
This news offered three unanswered questions:
A few days later, III Corps headquarters provided another explanation. It alleged that since General Hiếu was a pistol marksman who used to clean his own pistol, he accidentally shot himself. The question is how was it possible that such negligence could have created a wound at the chin, especially on the left side of the chin, while General Hiếu was right-handed.
Based on the bullet wounds location, General Hiếu could not have committed suicide – who would commit suicide by pointing the gun at the chin? That explains why the military spokesperson, when asked by a correspondent where, answered in the mouth to make it more believable.
All these various attempts in explanation from the military authority indicated an effort for a cover-up of an assassination ordered by General Toan’s immediate superior and carried out by General Toan’s clique right at the inner sanctum of III Corps headquarters.[12]
