    There is no DANFS history available for PT-73

    PT-73 under the command of Lt(jg) William R. McQuilkin and PT-75 had delivered supplies to the Mindoro guerrillas at Abra de Ilog and taken their leader aboard for the night's patrol. Close off Lubang Island, N.W. of Mindoro, PT-73 ran hard aground on an uncharted reef.

    LCDR Rowe, the guerrilla leader, said there was a garrison of about 300 enemy troops on the nearby island. Fearing an attack if the boat’s location became known, McQuilkin ordered the boat stripped
    and abandoned.

    After removing all important documents and equipment from their boat, the crew, of PT-73 was taken aboard PT-75 and the stranded hulk was torched to prevent capture.
