His men were trying to fight back by using the machine guns mounted in the PBYs, either by firing from inside the flaming planes or by detaching the guns and mounting them on improvised stands. In 2009 Finn explained one of the first things he did was take control of a machine gun from his squadron's painter. "I said, 'Alex, let me take that gun'...knew that I had more experience firing a machine gun than a painter."[3][4]
Finn then found a movable platform used for gunnery training, attached the .50 caliber machine gun, and pushed the platform into an open area, from which he had a clear view of the attacking aircraft. He fired on the Japanese planes for the next two hours, even after being seriously wounded, until the attack had ended. In total, he received 21 distinct wounds, including a bullet through the foot and an injury which caused him to lose feeling in his left arm.[1]
"I got that gun and I started shooting at Jap planes," Finn said in a 2009 interview. "I was out there shooting the Jap planes and just every so often I was a target for some," he said, "in some cases, I could see [the Japanese pilots'] faces."[4]
Despite his wounds, he returned to the hangars later that day, after receiving medical treatment, and helped arm the surviving American planes.[1][3]
