    PC-487 246k Crew members paint on their first victory of an Imperial Japanese Navy submarine
    "This U.S. Navy PC boat sank a Japanese submarine much larger than itself without assistance in the Pacific. On locating the undersea craft, the PC boat blew it to the surface with depth charges, then rammed it amidships. Circling to attack a second time, the PC's gun crews scored five direct hits on the submarine. Lt. W. G. Cornell, the PC boat commander, gave the order to ram again, and the enemy submarine sank--25 minutes after it was sighted."
