Quang Tri Province, between Route 9 and the DMZ; Ngan Valley (Helicopter Valley)
Objective
reconnaissance and search and destroy operation; combating PAVN thrust across the DMZ; redesignated Operation PRAIRIE on August 3, 1966
Description
Because Westmoreland disagreed with the Marine emphasis on counterinsurgency over large-unit operations against PAVN forces, he launched them on reconnaisance operations in the Quang Tri Province to measure PAVN buildup. The code name for these operations becam HASTINGS. Throughout the extent of HASTINGS, fighting occurred between Route 9 and the DMZ. The well-equiped PAVN division often ambushed the Marines. For the first time in the war, B-52s bombed the DMZ. Some of the heaviest fighting occurred the 12-25 July. The largest and most violent operation during the war at that time, HASTINGS ended the Marine emphasis on pacification and forced them to respond to the North Vietnamese and an expanded war.
