left a second burning and settling. The third, the towing vessel, cast loose and headed west under full steam. Sea Devil picked up three survivors and moved south to patrol in another area. Poor weather impaired hunting during the next six days. On 27 June, however, she was able to take photographs of Saishu To and Chiri To; and, on 29 June she was diverted to search and rescue operations. Assisted by a PB2Y Coronado and a PBM Mariner, she picked up a PBM crew from Rescue Squadron 4, Kerama Retto, on the evening of 30 June, then located the pilot of a United States Army Air Corps P-47 Thunderbolt based at Ie Shima. Another man, who had become separated, was located by accompanying aircraft the following morning and was picked up before noon. Fifth war patrol, August – September 1945 Sea Devil remained on life guard duty in the northern Ryukyu Islands and southern Kyūshū area until 10 July, then headed east to Guam for refit and the installation of LORAN equipment and a radio direction finder. On 9 August, she headed back to the Yellow Sea. On 14 August, she transited the Nansei Shoto, passing south of Akuseki Shima; and, on 15 August, after entering her patrol area, she received word of Japan's acceptance of Allied surrender terms. For another two weeks, Sea Devil remained in the area, looking for and sinking naval mines. On 27 August, she sighted a fishing vessel near a mine. Closer inspection showed that the fisherman was using the mine as a buoy and had secured his net to the mine horns. On 28 August, the submarine was ordered to Guam, then diverted to Subic Bay, where she arrived on 3 September. Within a few weeks, Sea Devil was joined by seven other submarines of the new, postwar submarine squadron, SubRon 5. Through the fall, she operated out of Subic Bay, conducting intensive training operations necessitated by a heavy turnover in personnel. On 1 December, she sailed for San Francisco, California, for overhaul and, on 23 April 1946, she returned to her home port, Pearl Harbor. 1946–1964 Three days later, SS-400 again headed west. On 16 May, she returned to Subic Bay; and, on 23 May, she continued on to Tsingtao where she provided antisubmarine warfare training services to TF 71 into July. On 5 May, she sailed for Shanghai, whence she proceeded
