Escape and Evasion Report of 2nd Lt. James M. Horton, 386th Squadron April 18, 1944 via Edward Rogers
"[April 15, 1944] However, shortly afterward a B-25 from the 345th Group circled us. About 5 minutes later 4 P-38's joined the 6-25. The Army "Cat" arrived after approximately 20 minutes had elapsed. It landed approximately S to N 45° to the wind and swells. The plane crashed and burned. We paddled over toward the wreckage as fast as we could to see if we could pick up any survivors; however there were none. All we found was a Mae West and some navigation charts, which we gave to the crew of the "Cat" which rescued us. About halfway to the crash the ammunition began to explode and the B-25 and P-38's buzzed us in an apparent attempt to keep us away from the crashed plane."
