What Happened in Vietnam in 1975 Two Years After We Left Vietnam?

In 1975, exactly two years after the United States completed its military withdrawal from Vietnam, North Vietnam launched a decisive offensive that led to the collapse of South Vietnam and the reunification of the country under communist rule. The pivotal event of this period was the Fall of Saigon, marking the conclusive end of the Vietnam War.

The Context: Two Years Post-US Withdrawal

The Paris Peace Accords, signed in January 1973, officially ended direct U.S. military involvement in Vietnam and mandated the withdrawal of all remaining American troops. By March 1973, the last U.S. combat forces had departed. While the agreement aimed for a peaceful resolution, it largely failed to prevent continued conflict between North and South Vietnam.

Despite the U.S. commitment to provide aid to South Vietnam, political scandals in the U.S. (like Watergate) and a wary American public led to reduced financial and military support. This weakening support, combined with an emboldened North Vietnam, set the stage for the dramatic events of 1975.

The Final Offensive and the Collapse of South Vietnam

In early 1975, North Vietnam initiated a large-scale military offensive, often referred to as the Spring Offensive. This campaign saw rapid advances by the People's Army of Vietnam (PAVN) against the Army of the Republic of Vietnam (ARVN). Without significant American air support or ground troops, South Vietnamese defenses crumbled far more quickly than anticipated.

Key events leading up to the end included:

• March 1975: North Vietnamese forces captured major cities like Huế and Da Nang, leading to a massive, chaotic retreat of ARVN forces and civilians southward.
• April 1975: The PAVN continued its relentless push towards Saigon, encircling the capital and tightening its grip on the remaining South Vietnamese territory.

The Fall of Saigon: April 30, 1975

The most significant event of 1975 was the Fall of Saigon, which occurred on April 30, 1975. This date signifies the definitive end of the Vietnam War.

• The Fall of Saigon was the capture of Saigon, the capital of South Vietnam, by North Vietnam and North Vietnam-controlled Viet Cong.
• As North Vietnamese tanks and troops closed in, a frantic evacuation effort, code-named Operation Frequent Wind, took place. Thousands of Americans, South Vietnamese allies, and foreign nationals were airlifted out of Saigon by helicopter from various locations, including the U.S. Embassy rooftop.
• The iconic images of helicopters ferrying people from the embassy became a powerful symbol of the war's conclusion and the hasty American departure.

On the morning of April 30, 1975, North Vietnamese tanks crashed through the gates of the Presidential Palace in Saigon, marking the official surrender of South Vietnam. Duong Van Minh, the last President of South Vietnam, announced the unconditional surrender, bringing decades of conflict to a close.

Immediate Aftermath

Following the Fall of Saigon:

• The Socialist Republic of Vietnam was established, unifying the country under communist rule.
• Saigon was renamed Ho Chi Minh City in honor of the revolutionary leader.
• Hundreds of thousands of South Vietnamese associated with the former regime, including military personnel and government officials, were sent to "re-education camps."
• A mass exodus of refugees, known as "boat people," fled Vietnam in the years that followed, seeking asylum in other countries.
