Serving, Saving, Shaping
Whenever a patrol spotted a U-boat, the crew broadcast its position to merchant ships in the area, as well as to the Navy and AAF. The CAP plane then stuck with the sub as long as possible to vector in any intercepting forces. The patrols also radioed in reports of tankers and merchant ships that had been hit, and the position of survivors in the water. CAP claimed its first U-boat kill on July 11, 1942, when Captain Johnny Haggins and Major Wynant Farr, flying a Grumman G-44 Widgeon armed with two depth charges, bombed a sub they had been shadowing for three hours, just as it came up to periscope depth.
