bow. Sea Robin then fired a spread of three torpedoes at the remaining ship, but the target zigged and they missed. On the second attempt, the ship was not so fortunate. After watching the target completely reverse course, the submarine fired three more torpedoes at a range of with one hit amidships that broke netlayer Nagaru Maru (856 tons) in half and sent her rapidly to the bottom. Sea Robin now began to pay the price for her success. For 24 hours, she was pursued by the escorts and accompanying aircraft; but made good her escape and arrived at Subic Bay, Philippines, on 15 March to replenish her depleted torpedo store. Departing Subic Bay on 19 March, Sea Robin set course for the South China Sea in the area of the island of Hainan where, on 23 March, she rescued a downed airman. On 30 March, the submarine found herself in the middle of a group of six Japanese destroyers. Midway between two of them, she launched three torpedoes at the first, but a quick turn of the ship caused them to pass harmlessly across the bow. The second destroyer swerved 90° and began to bear down on Sea Robin. After 20 minutes of depth charging, the submarine extricated herself and, with Hainan a scant away, again attacked, but a spread of six torpedoes failed to find a target, and the submarine resumed patrol. On 8 April, Sea Robin sank two small Japanese fishing vessels, taking three prisoners of war and, on the following day, took on board 10 more Japanese, survivors of a foundering trawler that had been attacked by Allied aircraft. The submarine terminated her second patrol at Pearl Harbor on 29 April. Third patrol, June – August 1945 Sea Robin departed Pearl Harbor 1 June on her third and final war patrol which was conducted in the Yellow Sea and East China Sea. She was in the East China Sea at , about southwest of Aogashima in the Nanpō Islands, on lifeguard duty in support of air raids on Japan by United States Army Air Forces B-29 Superfortress bombers on 26 June 1945 when a full load of bombs a B-29 had jettisoned through overcast landed in the sea only from her. She suffered no damage or casualties. After sinking a small patrol craft on 9 July and taking one prisoner, Sea Robin torpedoed and sank the
