USS Burrfish's fourth war patrol was from 18 September 1944 until December 2nd. She was part of a picket line with seven other submarines, north of Saipan, where she fired six torpedoes at enemy vessels. They all missed, but shortly after, she and USS Ronquil got into a surface gun battle with a heavily-armed Japanese patrol boat. The submarines won the engagement, but not without damage, as two of Burrfish's crew were wounded.
After a month in Pearl Harbour, Burrfish embarked on her fifth war patrol. She was on lifeguard duty, and on two occasions fired torpedoes at surface targets. Once again she missed, but suffered retaliatory attacks during which she suffered some damage. She was ultimately able to elude the harrying ships and aircraft, in spite of forty depth charges and twenty bombs coming her way. This patrol ended in Guam, on February 24th, 1945
Future posts in this series will cover the battered and bloodied Burrfish's final war patrol, her Cold War career in the US Navy, her time under the White Ensign with the Royal Canadian Navy, and her arrival at her final resting place.
