On April 7, 1943, a formation of Japanese fighters and dive-bombers was headed toward Tulagi Harbor. Scrambled from nearby Guadalcanal, USMC 1st Lt. James E. Swett of VMF-221 led his four F4F Wildcat division into the fray. Swett pursued and shot down three D3A2 Val enemy bombers before leveling out. Moments later, his Wildcat was hit by friendly fire. In spite of his damage, Swett dogged the fleeing Vals, scoring four more confirmed kills, and one probable, becoming an ace in his first combat mission. For this action, Lt. Swett was awarded the Medal of Honor.
