War Plan Orange
Upon activation of War Plan Orange, the 6th Pursuit Squadron and the rest of the PAAC were ordered to destroy their aircraft inventory. Capt. Villamor and his unit were ordered to a strategic retreat to Bataan and transformed their mission to air defense. Capt. Villamor ordered his unit to rally in Bataan and take up infantry and air defense roles. He would join Gen. MacArthur and Pres. Manuel L. Quezon on the ferry to Fort Mills on Corregidor Island on December 24, 1941. Capt. Villamor and his unit were still hoping to receive new aircraft from Australia. However, the shipment of the Pensacola Convoy never came through.
