 Marks' 3rd Brigade continued to find hastily abandoned camps and ammunition stores but failed, as did the 2nd Brigade, to regain contact with the 101st Regiment.On the 11th, therefore, DePuy shifted the 2nd Brigade under Lieutenant Colonel Sam S. Walker to search for a "700-man Viet Cong force" reported near the Bến Củi Plantation.Finding no trace of the unit, Walker went on to conduct a cordon and search operation at Bến Củi II, a hamlet inside the plantation, which agents had reported as a major VC supply point.
