South Vietnam surrenders - Apr 30, 1975 - HISTORY.com

By dawn, communist forces move into Saigon, where they meet only sporadic resistance. The South Vietnamese forces had collapsed under the rapid advancement of the North Vietnamese. The most recent fighting had begun in December 1974, when the North Vietnamese had launched a major attack against the lightly defended province of Phuoc Long, located due north of Saigon along the Cambodian border, overrunning the provincial capital at Phuoc Binh on January 6, 1975. Despite previous presidential promises to provide aid in such a scenario, the United States did nothing. By this time, Nixon had resigned from office and his successor, Gerald Ford, was unable to convince a hostile Congress to make good on Nixon’s earlier promises to rescue Saigon from communist takeover.

This situation emboldened the North Vietnamese, who launched a new campaign in March 1975. The South Vietnamese forces fell back in total disarray, and once again, the United States did nothing. The South Vietnamese abandoned Pleiku and Kontum in the Highlands with very little fighting. Then Quang Tri, Hue, and Da Nang fell to the communist onslaught. The North Vietnamese continued to attack south along the coast toward Saigon, defeating the South Vietnamese forces at each encounter.

The South Vietnamese 18th Division had fought a valiant battle at Xuan Loc, just to the east of Saigon, destroying three North Vietnamese divisions in the process. However, it proved to be the last battle in the defense of the Republic of South Vietnam. The South Vietnamese forces held out against the attackers until they ran out of tactical air support and weapons, finally abandoning Xuan Loc to the communists on April 21.

Having crushed the last major organized opposition before Saigon, the North Vietnamese got into position for the final assault. In Saigon, South Vietnamese President Nguyen Van Thieu resigned and transferred authority to Vice President Tran Van Huong before fleeing the city on April 25. By April 27, the North Vietnamese had completely encircled Saigon and began to maneuver for a complete takeover.

When they attacked at dawn on April 30, they met little resistance. North Vietnamese tanks crashed through the gates of the Presidential Palace and the war came to an end. North Vietnamese Col. Bui Tin accepted the surrender from Gen. Duong Van Minh, who had taken over after Tran Van Huong spent only one day in power. Tin explained to Minh, “You have nothing to fear. Between Vietnamese there are no victors and no vanquished. Only the Americans have been beaten. If you are patriots, consider this a moment of joy. The war for our country is over.”
