In early January 1973, the Nixon White House convinced the Thieu-Ky regime in Saigon that they would not abandon the GVN if they signed onto the peace accord.
On January 23, therefore, the final draft was initialed, ending open hostilities between the United States and the DRV. The Paris Peace Agreement did not end the conflict in Vietnam, however, as the Thieu-Ky regime continued to battle Communist forces. From March 1973 until the fall of Saigon on April 30, 1975, ARVN forces tried desperately to save the South from political and military collapse. The end finally came, however, as DRV tanks rolled south along National Highway One. On the morning of April 30, Communist forces captured the presidential palace in Saigon, ending the Second Indochina War.
