USS PLUNGER (SS-179) was underway during her tenth war patrol. Having sighted a puff of smoke on the horizon, PLUNGER gave chase. She tracked the smoke for two hours before her diligence paid off. PLUNGER sighted a convoy consisting of three large merchant ships and two escorts. PLUNGER selected the two largest ships as her intended victims. The first ship, dubbed "PAPA," was engaged using PLUNGERís final forward torpedo. This shot struck PAPA amidships, setting her aflame. Before PLUNGER could engage her next target, named "MAMA," she was subjected to a vigorous depth charging.
