The victory at Xuân Lộc, which had drawn many South Vietnamese troops away from the Mekong Delta area, opened the way for PAVN to encircle Saigon, and they soon did so, moving 100,000 troops in position around the city by 27 April. With the ARVN having few defenders, the fate of the city was effectively sealed. The ARVN III Corps commander, General Toàn, had organized five centers of resistance to defend the city. These fronts were so connected as to form an arc enveloping the entire area west, north, and east of the capital.

South Vietnamese defensive forces around Saigon totalled approximately 60,000 troops.

Many feared that once the communists took control of the city, a bloodbath of reprisals would take place. In 1968, PAVN and VC forces had occupied Huế for close to a month. After the communists were repelled, American and ARVN forces had found mass graves. A study indicated that the VC had targeted ARVN officers, Roman Catholics, intellectuals, businessmen, and other suspected counterrevolutionaries. More recently, eight Americans captured in Buôn Ma Thuột had vanished and reports of beheadings and other executions were filtering through from Huế and Đà Nẵng, mostly spurred
