When the weekend of Easter 1972 arrived, General Giai had planned to rotate the operational areas of his 56th Regiment (along the central DMZ) with the 2nd Regiment (around the artillery base at Camp Carroll in the west). Because of a truck shortage, the units were moved simultaneously and became hopelessly intermixed and disorganized. At 11:30 on 30 March, both unit headquarters shut down their radios, for the exchange of operational areas. With communications fragmented, its units entangled, and the weather bad enough to prevent aerial operations, the 3rd Division offered the massed PAVN forces to the north an irresistible target.
