The torpedo hit the engine, a fire room and crew compartment that disabling all power and communications and the abandon ship sounded but only heard on part of the vessel. Two minutes, the stern began to sink with the after portion of the well deck awash. managed to continue for three miles before it lost all power and began to sink.

The crew was able to deploy two life rafts and all six PT Boats were freed from their cradles but PT-165 and PT-173 were so badly damaged they were scuttled. At 12:05pm the damaged ship sank and corkscrewed as the bow heaved upwards. One of the life rafts capsized and were picked up by the four surviving PT Boats.

During the torpedoing and sinking, twelve of the crew were lost: 1 U.S. Merchant Seaman Leroy Tilley, 7 Filipino seamen Victor Armaso, Catalino Masa, Apalonio Cacitoit, Gervasio Sallader [Sallador], EIpidio M. de Vega, Nicolas Palaspas and Santiago Flores.
