巴士海峽
On 5 February 1944 "Pogy" departed Midway on her fifth war patrol for an anti-shipping sweep of the Formosa area. During the morning of 10 February, she spotted a convoy in Bashi Channel, off the southern tip of Formosa, guarded by three Japanese destroyers. "Pogy" attacked with five torpedoes, sinking Japanese destroyer "Minekaze" and 5,500-ton passengercargo ship "Malta Maru", and damaging another freighter.
