On the afternoon of 17 March four LOHs and one UH-1 command and control helicopter began the initial reconnaissance of the 11th ACR's area of operation. Upon arriving over the northeast Michelin Plantation it soon became evident that the area was being occupied by a large PAVN force. Large groups of PAVN troops were seen in the rubber trees and clearance to fire was requested. While waiting for clearance the PAVN made little or no attempt to hide from the helicopters. After a 90-minute wait the Air Cavalry Troop was given clearance to engage the PAVN and throughout the day tactical air strikes were directed against the PAVN. Two AH-1 Cobras remained on station throughout the day and made repeated strikes against the PAVN. One LOH was damaged by ground fire and landed at Lai Khê for repairs. 30 dead PAVN were counted from the air. As a result of these engagements the area of operations was moved into the Michelin Plantation and the 1st and 3rd Squadrons 11th ACR were committed to the operation.[1]^:3–4[2]^:1[3]
