November 30: In one of the largest aerial battles of the war, F-86 pilots of the 4th FIG engaged over the island of Taehwa-do forty-four enemy aircraft flying south to bomb a UN target. The Sabre pilots destroyed twelve and damaged three others. Maj. George A. Davis Jr., USAF, 334th FIS, achieved Korean War ace status by downing a TU-2 and a MiG-15. He was the first to be an ace in two wars, since he had been an ace in World War II as well. Maj. Winton W. Marshal, USAF, 335 FIS, also became an ace, destroying an LA-9 and a TU-2. Enemy forces attacked Taehwa-do, north of Cho-do, forcing friendly forces to retreat to Cho-do. Fifth Air Force aircraft dislodged the enemy, enabling friendly forces to retake the island.
