Originally given the task of escorting US Army Air Force bombers to attack Kahili Airfield on Bougainville island, the US Marine Corps F4U fighters arrived earlier than the bombers, thus the mission became a fighter sweep of the Japanese airfield. 22 Japanese A6M fighters rose to defend. USMC pilot Bill Case claimed 2 victories, Tom Emrich 2, Burney Tucker 1, and Gregory Boyington 1. Japanese records would later reveal that only 1 fighter was destroyed on this day Facility
