On her Sixth War Patrol, WAHOO conducted nine separate torpedo attacks without sinking a single enemy ship.  Malfunctioning torpedoes which ran erratically, exploded prematurely or failed to detonate upon striking the target were sighted by Captain Morton as the cause for this unsuccessful run.     However, WAHOO did not return without her victims.  During her return from the Sea of Japan, Morton battle surfaced on three separate occasions to sink a sampan with his deck guns.
