"Appendix V : Unit Losses: January 3, 1945: Col. Grant Mahoney [sic] (HQ). P-38. He tagged along on a strafing mission to Puerta Princesa on Palawan, P.I. Lieutenant George Lynch (35th Sq) offered to yield the lead and go along as wingman. Col. Mahoney [sic] saw a floatplane in the harbor near the airfield and, even though Lynch warned him that the thing was probably a dummy zeroed in by anti-aircraft, decided to attack. On the way down Lynch could see the flashes of guns on the ground, and silenced some of them with strafing fire, but not before Mahoney [sic] was hit and went straight into the ground. Mahoney [sic] was a hero of the China-Burma-India theater and Lynch's impression of the brief time that he knew the Colonel was that he was a fine officer."
