April 30, 1975: The Fall of Saigon

30 April 1975, the final chapter of US engagement in the Vietnam conflict came to a close when Saigon fell to the communists of North Vietnam.

The signing of the Paris Accords in 1973 signaled the end of US military involvement in South Vietnam, and CIA’s mission was confined specifically to providing intelligence supported Still, South Vietnam and the government of Nguyen Van Thieu remained dependent on US financial and material assistance.

A December 1974 National Intelligence Estimate highlighted an unprecedented buildup of Communist forces in the South. The estimate noted that without an immediate increase in US assistance, South Vietnam’s military situation would become parlous, and it also raised the specter of an all-out Communist offensive. Weariness and popular disenchantment with the war—as well as the Wa- tergate scandal that weakened the administration of President Richard Nixon—led Congress in the fall of 1974 and again in the spring of 1975 to rebuff the Ford administration’s requests for additional military appropriations to support the Thieu government
Early in March 1975, the North’s final offensive began in earnest.

Two major military setbacks—the inexplicable, voluntary withdrawal of South Vietnamese forces from the northern panhandle and the Central Highlands and the subsequent fall of Da Nang, South Vietnam’s second-largest city—offered an opening and an opportunity for the Communists to bring it to the final conclusion-Saigon. CIA files chronicle the ending of the war.

For many in America, the Vietnam War ended in 1973 with the signing of the Paris Peace Accords and the subsequent withdrawal of the U.S. military from Vietnam a few months later. The United States’ involvement in South Vietnam, however, lasted for two more years. Many believed that with continued American financial support and guidance, South Vietnam could maintain its status as an independent state. To help pursue this goal, a token force of 159 U.S. Marines were left behind to secure the U.S. embassy and Consul General’s offices in Da Nang, Nha Trang, Bien Hoa, and Can Tho; another 50 military officers remained to create the new Defense Attache’s Office (DAO). The DAO monitored the situation in South Vietnam, managed U.S. aid and the distribution of munitions and weapons to the Army of the Republic of Vietnam (ARVN), and provided support to the U.S. contractors remaining in Vietnam.

The new status quo held in Vietnam until the end of 1974 when several factors led to the demise of South Vietnam. The Arab-Israeli War of 1973 triggered an economic crisis with rising inflation and soaring petroleum prices causing problems all over the world, and, more significantly, angered American consumers. The political environment in America had changed drastically: President Richard Nixon resigned from office in August of 1974 and the American people were becoming increasingly vocal against continuing aid for a war that had supposedly ended in 1973. Eventually, Congress bowed to the pressure and significantly cut Vietnam’s military and financial aid. Faced with a money shortage and high inflation, South Vietnam was suddenly unable to purchase the weapons necessary to engage the North Vietnamese army. During this time of crisis, the North Vietnamese secretly planned a major offensive meant to push deeply into South Vietnam’s territory in early 1975.

In January 1975, Phuoc Long fell to the communists. The South Vietnamese government had always believed that if the North Vietnamese violated the terms of the Paris Peace Accords the Americans would return with force to help them. President Thieu asked for more aid to help regain the lost territory, but unfortunately for South Vietnam, the time for massive American aid had passed. Congress sent a delegation to Vietnam to judge the situation, and while they did recommend an immediate increase in aid to South Vietnam, the situation continued to deteriorate and it became apparent that South Vietnam could not survive much longer. 

The fall of Ban Me Thuot on March 10 affected the situation in two distinct ways. First, Paul Struharik, the U.S Province Representative for Darlac, and several American missionaries were captured in the defeat. Second, several Vietnamese employees of Air America were captured and executed by the North Vietnamese. The captured Americans, combined with the ARVN losses, convinced Congress to deny further aid to South Vietnam and to urge the Americans remaining in-country to plan for a final evacuation. The executions sparked a mass panic across South Vietnam, causing both civilians and military personnel to flee in the face of the communist army, often before a shot was even fired. As the panic continued, Thieu, fearing for his own safety, pulled the elite airborne rangers out of I and II Corps and moved them into Saigon to defend the capital. These actions destabilized the situation in the northern provinces of South Vietnam and allowed the North Vietnamese to take I and II Corps virtually unopposed.

At home, Americans watched their televisions with horror and anger as cities and towns with names that were familiar to them from their service in Vietnam were once again featured on the evening news. One by one, the cities began falling to the North Vietnamese: Qui Nhon and Nha Trang on April 1, Cam Ranh on April 3, Phan Rang on April 15, and Phan Thiet on April 19. The political situation in Saigon rapidly deteriorated and the North Vietnamese government made it clear that they would not negotiate with Thieu. On April 21, Thieu resigned the presidency with the hope that his successor would be able to negotiate better surrender terms with Hanoi. Over the next week the presidency changed hands twice, finally settling on General Duong Van Minh, also known as “Big Minh.” On April 29, the North Vietnamese established positions outside of Saigon and began shelling Tan Son Nhut air base. Twenty-four hours later, the last of the Americans had left and the North Vietnamese came streaming into the city.
