Swett repeatedly attacked the line of dive bombers, downing each in turn with short bursts. He brought down four and was attacking a fifth when his ammunition was depleted and his cockpit was shot up by return fire. Wounded, he decided to ditch his damaged fighter off the coast of Florida Island, after it became clear that his oil cooler had been hit and he would not make it back to base. After a few seconds his engine seized, and despite initially being trapped in his cockpit underwater, Swett extricated himself and was rescued in Tulagi harbor after ditching his plane. This feat made the 22-year-old Marine aviator an ace on his first combat mission.
