Tet and the Popular Uprising at Hue

When the Tet Offensive erupted, American and international media attention focused on the spectacular Vietcong attacks in Saigon. On January 31, millions of American television viewers watched as U.S. military police attempted to root out and kill the Vietcong still holed up in the U.S. embassy grounds. The viewing public also saw in vivid techno-color Vietcong sappers, who had barricaded themselves inside the Saigon radio station, detonate a massive explosive charge, killing themselves and destroying the communications facility. In the most memorable incident of the entire Tet Offensive, photographer Eddie Adams and a NBC camera crew captured on film the moment Chief of the South Vietnamese National Police General Nguyen Ngoc Loan executed Vietcong prisoner Nguyen Van Lem with a single pistol shot to the head. Notwithstanding the visual impact of those television images, and their influence on public perceptions of the war, the militarily significant attacks, and the ones that indicated that the Vietcong had successfully orchestrated a series of popular uprisings, occurred elsewhere.

The most stunning Communist achievement during the Tet Offensive took place at Hue. While General William C. Westmoreland and MACV intelligence chief General Phillip Davidson focused their attentions on the Marine combat base at Khe Sanh, the Communists made preparations to seize Hue. As a precursor to the attack on the city, the Communists pre-positioned troops and supplies at two jumping-off points – one in the A Shau Valley to the west and another north of the DMZ in the vicinity of the Vinh Moc tunnel complex.

North Vietnamese units had dominated the A Shau Valley since 1966, transforming it into one of their biggest logistical bases in South Vietnam. The Americans avoided the A Shau because it sat immediately east of the border with Laos and the Communist base areas there. Sizeable North Vietnamese units, marching south on the main truck routes in Laos or stationed in their Laotian base camps, could quickly pivot eastward and charge into the A Shau to contest any U.S. incursion.

The A Shau’s unpredictable weather further limited American access to the valley.  Thick clouds, rain, fog, and high winds all-too-frequently blew into the valley, grounding U.S. helicopters, transport planes, and the fighter-bombers needed to support foot soldiers. Terrain and vegetation added to the difficulties of fighting there. High timbered hills flanked the valley floor – the very sort of environment that favored dug-in Communist defenders. In describing the A Shau, General John R. Tolson of the 1st Cavalry Division said, “This valley is one of the weirdest pieces of terrain I’ve ever seen…It’s a great big ditch among a whole bunch of hills. The valley floor is 2,000 feet deep.”[1]

In peacetime, Route 547 carried overland traffic between the A Shau and Hue. But by 1968, the North Vietnamese and Vietcong dominated the hills overlooking Route 547. Any American or ARVN convoy attempting to enter the A Shau over Route 547 stood a good chance of being ambushed. The A Shau was a “no go” zone, an area deep in what the Americans called “Indian Country.”[2]

In the final days of January 1968, eight Communist battalions, or approximately 4,000 men, stepped quietly out of the A Shau and began walking the 22 miles toward Hue. Observing strict noise discipline and hidden by clouds and mist, the Americans never saw nor heard them coming. Route 547 carried them to the western edge of the coastal plain, where they bivouacked and made final plans for the capture of Hue. After sundown on the evening of January 30, the Communist troops again set out, marching along the north and south banks of the Song Huong Giang, known in English as the “River of Perfumes.” As they passed friendly hamlets, the villagers joined the columns of men, volunteering as porters, stretcher-bearers, and guides. Near the city proper, the Communist soldiers skirted the Tomb of Emperor Minh Mang, its former groomed grounds overgrown with vines and trees and its moats brimming with lotuses. Tourists rarely visited the tomb anymore, deeming the site too dangerous because of the Vietcong known to be living in the nearby hamlets.[3] The North Vietnamese and Vietcong soldiers quickened their pace after they passed the Linh Mu Pagoda, three miles west of the citadel, the walled fortress that enclosed the former imperial city.[4]

Early on the morning of January 31, the guerrillas and North Vietnamese regulars, armed with AK-47s and RPGs, trotted up and over the pavement of National Route 1 and then across the railroad tracks below the tall, thick brick walls of the citadel. Other units pushed into Hue south of the Perfume River, rushing on toward the American university and MACV headquarters situated on the south end of the city’s picturesque suspension bridge. By sunrise on January 31, the Communists occupied almost every foot of the citadel, with the exception of its northeast corner, where ARVN rangers held on desperately against the powerful forces arrayed against them. That the North Vietnamese and Vietcong had been able to get into Hue at all came as a shock to the American troops based at Phu Bai. W.D. Ehrhart, with the Marines eight miles south of the city, remembered the surprise he and his fellow grunts felt when they first learned that the Communists had taken Hue and that no one on the South Vietnamese side had forewarned the Americans of their approach.[5]

In subsequent days, the North Vietnamese and Vietcong succeeded in reinforcing their positions in the citadel. Two Communist LOCs, or Lines of Communication, provided the Hue forces with ammunition, food, and replacements. One LOC extended from the DMZ southward along trails and dirt roads between Highway 1 and the South China Sea. This LOC went through a region known since the First Indochina War as the Street Without Joy. The existence of this LOC meant one thing – after three years, the Americans had still not pacified the Street Without Joy – its residents remained solidly Vietcong. A second LOC linked the citadel to the A Shau Valley via a string of Vietcong hamlets west of Hue. Five enemy battalions, or 2,500 men, entered Hue after the start of the battle along this route before U.S. units uncovered it and deployed a blocking force across its path.[6] The Hue-A Shau route, like the one through the Street Without Joy, pointed to widespread popular support for the Communists amongst the rural population living in the lowlands between Hue and the mountains.

The successful Communist seizure of Hue depended on the people of Hue and its environs.  Local peasants and the radicalized youth of Hue made Communist occupation of the city possible. Ms. Hoang Lanh, who served with the Vietcong at Hue during the Tet Offensive, believed that a popular uprising occurred at Hue and in the area around it. She recalled, “…in Hue we conducted a mass mobilization. The people brought us food, they hid us, and took us to the road and showed us the way. Hospitals were set up to treat the wounded. Thousands and thousands of soldiers and officers were taken in by the people of Hue.”[7]

General William C. Westmoreland, always loath to acknowledge the popularity of the Vietcong and North Vietnamese, later confessed that a fifth column helped the enemy at Hue. The American general neither specified the size nor composition of that fifth column. He refused to clarify whether it consisted of tens of thousands of rural residents, thousands of city dwellers, or a combination of both groups.  He merely stated that, “…enemy regular units…were able to infiltrate Hue with the help of accomplices inside the city.”[8] As it turned out, both South Vietnamese peasants and South Vietnamese urban residents aided the Communists at Hue.  And it was that popular uprising which enabled the North Vietnamese and Vietcong to seize Hue right under the noses of the Americans and then hold portions of the city and its environs for over a month.
