Editing USS Cod (section)

==World War II==

On 30 August 1943, the American [[Type C1 ship|Type C1-B]] [[cargo ship]] SS ''Alcoa Patriot'' opened gunfire on ''Cod'' in the [[Caribbean Sea]] at {{coord|12|25|N|076|03|W}}, about {{convert|120|nmi}} north-northwest of [[Barranquilla, Colombia]], and {{convert|330|nmi}} east of the northern entrance to the [[Panama Canal]]. Less than three hours later, ''Alcoa Patriot'' again sighted ''Cod'' and fired on her at {{coord|12|02|N|076|04|W}}, about {{convert|105|nmi}} northwest of Barranquilla and {{convert|310|nmi}} east of the northern entrance to the [[Panama Canal]]. ''Cod'' suffered no damage or casualties in either incident.<ref>Hinman & Campbell, pp. 37–38.</ref>

===First patrol, October 1943 – January 1944 ===
''Cod'' arrived in [[Brisbane, Australia]], on 2 October 1943 to prepare for her first [[Patrolling|war patrol]]. She sailed from there 20&nbsp;days later. Penetrating the [[South China Sea]], she contacted few targets, and launched an attack only once, on 29 November, with unobserved results. She returned to [[Fremantle, Australia]], to refit from 16 December 1943 to 11 January 1944.

===Second patrol, February 1944 – March 1944 ===
''Cod'' put to sea for her second war patrol in the South China Sea, off [[Java (island)|Java]], and off [[Halmahera]]. On 16 February, she surfaced to sink a [[sampan]] by gunfire, and on 23 February, [[torpedo]]ed a Japanese [[cargo ship|merchantman]]. She sent another to the bottom on 27 February, ''Taisoku Maru'' (2,473 tons) and two days later attacked a third, only to be forced deep by a concentrated [[depth charge|depth charging]] delivered by a Japanese escort ship.

===Third patrol, March 1944 – June 1944 ===
Refitting at Fremantle again from 13 March – 6 April 1944, ''Cod'' sailed to the [[Sulu Sea]] and the South China Sea off [[Luzon]] for her third war patrol. On 10 May, she attacked a heavily escorted [[convoy]] of 32 ships and sank the [[destroyer]] [[Japanese destroyer Karukaya|''Karukaya'']] and cargo merchantman ''Shohei Maru'' (7,256 tons) before the escorts drove her down with [[depth charges]]. She returned to Fremantle to replenish on 1 June 1944.

===Fourth patrol, July 1944  – August 1944 ===
''Cod'' was put to sea again 3 July on her fourth war patrol. She ranged from the coast of Luzon to Java. She sank the converted [[net tender]], ''Seiko Maru'' (708 tons) on 3 August, and a [[landing craft]], ''LSV-129'', on 14 August, and, once more successful, she returned to Fremantle 25 August.

===Fifth patrol, September 1944  – November 1944 ===
''Cod'' put to sea on her fifth war patrol 18 September 1944, bound for [[Philippines|Philippine]] waters. She made her first contact, a cargo ship, ''Tatsushiro Maru'' (6,886 tons) on 5 October, and sank it. Two days later, she inflicted heavy damage on a tanker. Contacting a large convoy on 25 October, ''Cod'' launched several attacks without success. With all her torpedoes expended, she continued to shadow the convoy for another day to report its position. In November she took up a lifeguard station off Luzon, ready to rescue carrier pilots carrying out the series of air strikes on Japanese bases which paved the way for the [[Battle of Leyte]] later that month.

''Cod'' returned to [[Pearl Harbor Naval Base]] on 20 November 1944, and sailed on to a stateside overhaul at [[Mare Island Naval Shipyard]], returning to [[Pearl Harbor]] on 7 March 1945.

===Sixth patrol, March 1945 – May 1945 ===
On 24 March she sailed from Pearl Harbor for the East China Sea on her sixth war patrol. Assigned primarily to lifeguard duty, she used her deck gun to sink a [[tugboat]] and its tow on 17 April, rescuing three survivors, and on 24 April launched an attack on a convoy which resulted in the most severe depth charging of her career. The next day, she sent the [[minesweeper (ship)|minesweeper]] ''W-41'' to the bottom. On 26 April ''Cod'' was threatened by a fire in the aft torpedo room, but the ship's crew brought the fire under control and manually launched a torpedo already in its tube before the fire could detonate it. QM2c Lawrence E. Foley and S1c Andrew G. Johnson were washed overboard while freeing the torpedo room hatch. Foley was recovered the next morning, but Johnson drowned during the night. This was ''Cod''{{'s}} only fatality during [[World War II]].<ref>McDaniel, J.T., Ed.

===Seventh patrol, May 1945 – June 1946 ===
[[File:Hr. Ms. O 19 op rif.jpg|thumb|left|[[HNLMS O 19|''O-19'']] stuck on [[Ladd Reef]]]]
After refitting at [[Guam]] between 29 May and 26 June 1945, ''Cod'' put out for the [[Gulf of Siam]] and the coast of [[Indo-China]] on her seventh war patrol. On 9 and 10 July she went to the rescue of a grounded [[Royal Netherlands Navy|Dutch]] submarine, [[HNLMS O 19|''O-19'']], taking its crew on board and destroying the Dutch submarine when it could not be gotten off the reef. This was the only international submarine-to-submarine rescue in history. After returning the Dutch sailors to [[U.S. Naval Base Subic Bay]], between 21 July and 1 August ''Cod'' made 20 gunfire attacks on the junks, motor sampans, and barges which were all that remained to supply the Japanese at [[Singapore]]. After inspecting each contact to rescue civilian crew, ''Cod'' sank it by gunfire and torpedoes, sending to the bottom a total of 23. On 1 August, an enemy plane [[Strafing|strafed]] ''Cod'', forcing her to dive, leaving one of her boarding parties behind. The men were rescued two days later by {{USS|Blenny|SS-324}}.

When ''Cod'' returned to Fremantle 13 August 1945, the crew of ''O-19'' was waiting to throw a party for their rescuers. During that celebration, the two crews learned of the Japanese surrender. To symbolize that moment, another symbol was added to ''Cod''{{'s}} battle flag: the name ''O-19'' under a [[martini glass]].<ref>{{cite web |last1=Farace |first1=Paul |title=A brief history of the U.S.S.

''Cod'' sailed for home on 31 August. Arriving at [[Naval Submarine Base New London]], on 3 November after a visit to [[Miami, Florida]], ''Cod'' sailed to the [[Philadelphia Navy Yard]] for a overhaul, returning to [[New London, Connecticut]] where she was decommissioned and placed in reserve 22 June 1946.

===Post-War service, June 1946 – June 1954===
''Cod'' was [[United States Navy reserve fleets|mothballed]] in 1946, ''Cod'' was recommissioned in 1951 to participate in [[NATO]] anti-submarine training exercises. During the [[Cold War]], ''Cod'' traveled to [[St. John's, Newfoundland]], as well as [[Cuba]] and [[South America]].
