Maritime 2: Anti-submarine activities of the 113 Squadron
113 Squadron was affiliated with the Royal Canadian Air Force. After 1942, the squadron was mainly responsible for attacking and guarding German U-boats. On July 31, 1942, the captain of the 113 Squadron, N.E. Small, sank a German submarine at Sable Island. The sunken submarine was later confirmed to be the German U-754. Not only that, the 113 Squadron was also active near the St. Lawrence River, because in May, German submarines had infiltrated the area near the river, seriously threatening the safety of the transport fleet. On September 9, a detachment of the 113 Squadron discovered U-165 while patrolling. Although the submarine was not sunk, the attack drove the Germans out of the area. In the following 20 days, the 113 Squadron attacked another submarine, U-517, three times, causing it to be seriously damaged and escape from the St. Lawrence River area. The activeness of the 113 Squadron ensured the transportation of Allied supplies and cracked down on German submarine activities in waters near Canada. The picture shows an aircraft from the 113 Squadron attacking a German submarine on September 9.
