On September 17, 1939, the Royal Navy aircraft carrier HMS Courageous was hit by torpedoes from the German submarine U-29, and sank within 20 minutes. The Courageous, on an anti-submarine patrol off the coast of Ireland, was stalked for hours by U-29, which launched three torpedoes when it saw an opening. Two of the torpedoes struck the ship on the port side, sinking it with the loss of 518 of its 1,259 crew members. (AP Photo) #
