Phuoc Binh, the capital of Phuoc Long Province, about 60 miles north of Saigon, falls to the North Vietnamese. Phuoc Binh was the first provincial capital taken by the communists since the fall of Quang Tri on May 1, 1972.
Two days later, the North Vietnamese took the last of the South Vietnamese positions in the region, gaining control of the entire province. The South Vietnamese Air Force lost 20 planes defending the province. Presidents Nixon and Ford had promised South Vietnamese President Nguyen Van Thieu that the United States would come to the aid of South Vietnam if the North Vietnamese launched a major offensive in violation of the Paris Peace Accords. However, the United States did nothing when Phuoc Binh fell to the communists. In fact, the passive response of the United States convinced North Vietnam that the Americans would not soon return to Vietnam, and encouraged the Politburo in Hanoi to launch a new attack in the hopes of creating ripe conditions for a general uprising in South Vietnam by 1976.
When the North Vietnamese launched the new offensive in early 1975, the South Vietnamese forces, demoralized by the failure of the United States to come to their aid, were defeated in just 55 days. North Vietnamese tanks crashed through the gates of the presidential palace on April 30 and South Vietnam surrendered fully to the communists.
