The Pensacola Convoy is a colloquialism for a United States military shipping convoy that took place in late 1941 as the Pacific War began. The name was derived from that of its primary escort ship, the heavy cruiser USS Pensacola. Pensacola was officially designated Task Group 15.5 and Army sources may use the term Republic convoy for the senior convoy vessel.[1][2] The convoy, dispatched in peacetime, was intended to reinforce the United States Army Forces Far East (USAFFE), created to defend the U.S. Commonwealth of the Philippines and commanded by General Douglas MacArthur, with artillery, aircraft, munitions and fuel, as the threat of war with the Empire of Japan loomed.[3] After war broke out, and Japanese forces attacked the Philippines, the convoy was diverted to Brisbane, Australia.
