On 29 April a South Vietnamese armored task force crossed the Cambodian border into the area known as the Parrot's Beak, northwest of Saigon. The following day a multi-division U.S./South Vietnamese force rolled over the border and into the area known as the Fishhook, north of Saigon and opposite Bình Long Province. With the exception of heavy fighting at Snuol, PAVN/VC resistance was light since most of the North Vietnamese had been withdrawn from the border regions for operations against FANK. In quick succession, all of the border sanctuaries were struck, to one degree or another, by U.S. or South Vietnamese forces.
