After a weeklong mission to South Vietnam, Gen. Frederick Weyand, U.S. Army Chief of Staff and former Vietnam commander, reports to Congress that South Vietnam cannot survive without additional military aid. Questioned again later by reporters who asked if South Vietnam could survive with additional aid, Weyand replied there was "a chance."
Weyand had been sent to Saigon by President Gerald Ford to assess the South Vietnamese forces and their chances for survival against the attacking North Vietnamese. The South Vietnamese were on the verge of collapse. The most recent assaults had begun in December 1974 when the North Vietnamese launched a major attack against the lightly defended province of Phuoc Long--located north of Saigon along the Cambodian border--and overran the provincial capital at Phuoc Binh on January 6, 1975. Despite previous presidential promises to aid South Vietnam in such a situation, 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 Saigon.
The situation emboldened the North Vietnamese, who launched a new campaign in March 1975, in which the South Vietnamese forces fell back in total disarray. 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.
As Weyand reported to Congress, the South Vietnamese were battling three North Vietnamese divisions at Xuan Loc, the last defense line before Saigon. Indeed, it became the last battle in the defense of the Republic of South Vietnam. The South Vietnamese forces managed to hold out against the attackers until they ran out of tactical air support and weapons, finally abandoning Xuan Loc to the communists on April 21. Saigon fell to the communists on April 30.
