The communists renamed the city after Ho Chi Minh, former President of North Vietnam, although this name was not frequently used outside official business. Order was slowly restored, although the by-then-deserted U.S. Embassy was looted, along with many other businesses. Communications between the outside world and Saigon were cut. The Viet Cong machinery in South Vietnam was weakened, owing in part to the Phoenix Program, so the PAVN was responsible for maintaining order and General Trần Văn Trà, Dung's administrative deputy, was placed in charge of the city. The new authorities held a victory rally on May 7.
