cargo ship, Sakishima Maru, on 10 July. Shortly thereafter, while attempting to sink a large sampan, the submarine was caught on the surface by a Japanese plane. Although the pilot did not drop his bombs on the first pass, thus giving Sea Robin a chance to dive, he dropped two close aboard on the second. Although it was not discovered until the end of the patrol, the submarine's bow tubes were severely damaged causing numerous torpedo misses throughout the remainder of the patrol. With the exception of several trawlers sunk in surface attacks, the remainder of the patrol was unproductive. When the war ended on 15 August, Sea Robin was moored at Midway Island. After a one-day stop at Pearl Harbor, the boat headed for home, transiting the Panama Canal on 20 September and arriving at Galveston, Texas, four days later. 1945 – 1951 Peacetime assignment brought Sea Robin to Submarine Squadron 6 (SubRon 6) based at Balboa, Canal Zone. On 15 May 1947, the submarine commenced a -month simulated war patrol in which she circumnavigated the South American continent and became the first U.S. submarine to round Cape Horn. The year 1948 was spent in fleet training exercises in the Balboa and Key West areas. Following overhaul at the Philadelphia Naval Shipyard, Sea Robin was reassigned to SubRon 8 based at Naval Submarine Base New London, arriving on 20 August 1949. On 23 February 1950, the submarine departed New London for participation in Exercise "Portex," a joint Army-Navy-Air Force exercise in the Caribbean, returning on 23 March. From September through November, she was engaged in her first tour of duty with the 6th Fleet in the Mediterranean. 1951 – 1955 In 1951, Sea Robin was converted to a GUPPY IA submarine, following which she returned to New London for local operations. In January and February 1952, the submarine participated in Exercise "Micowex" in the North Atlantic testing cold weather gear and procedures under the supervision of the Naval Research Laboratory, New London, followed by a return to warmer waters and participation in Exercise "Pacex" in the Caribbean. For the next two years, Sea Robin was engaged in local fleet and training operations in the New London area. On 30 August 1954, Sea Robin set sail for a six-week northern training cruise which stretched across the Arctic Circle and included stops at Glasgow, Scotland; and Belfast, Northern Ireland. On 4
