ww2dbaseCommissioned in Dec 1942, Commander Samuel Dealey took USS Harder out of Pearl Harbor, US Territory of Hawaii for the submarine's first war patrol in Jun 1943. All six of her war patrols would be deemed successful, and Commander Dealey would be known for his aggressiveness in seeking out Japanese shipping, sinking several Japanese destroyers (including Minazuki, Hayanami, Tanikaze, and others) in addition to a number of merchant ships. Her most successful war patrol was her fifth, during which she sank or heavily damaged four destroyers. On 24 Aug 1944, while attacking two Japanese destroyers off Dasol Bay, Luzon, Philippine Islands together with wolfpack mate USS Hake, Harder was depth charged and sunk by coastal defense ships CD-22 and PB-102, the latter of which was the former USS Stewart captured by the Japanese at Surabaya, Java, Dutch East Indies in 1942.

The precise resting place of USS Harder is not known. Post-war estimates based on debriefings place the approximate location at 15.833333N, 119.166667E. This location is nearly right on top of the Manila Trench which in this area is about 14,000 feet deep (4,267m). One submarine website estimates Harder’s resting place at 15.837281N, 119.780852E which is right in the mouth of Dasol Bay and about 80 feet deep (24m).

I wonder why the lost 52 project does not go looking for the Harder. You would think it should be pretty easy to find. The general area is known just off dasol bay. The hake made a periscope observation and the *** were in sight of land they must have recorded the sight you would think.
