The main Group formation of 20 B-17s of the 358th, 359th, and 427th Squadrons was led by 359th BS(H) CO Maj. William Calhoun, pilot, and Lt. Col. Eugene Romig, Operations Officer, co-pilot, in The ‘8’ Ball MkII. Maj. Lewis Lyle, CO, 360th BS, led seven of the 360th’s B-17s as part of a composite Squadron with the 379th BG(H). The 303rd BG(H) dropped 57 1/2 tons of 500-lb. bombs from 26,000 feet on the target area. Flak was reported as moderate, but accurate.
About one-third of the crew, it is believed, were never able to leave the U-boat. A well-placed stick of bombs hit U-118 forward of the conning tower and blew her in two, the boat seeming to break apart in the middle. One survivor swimming nearby, said he saw Czygan, his white shirt covered with blood, kneeling on the bridge as his ship disappeared in a fountain of spray and debris. All survivors believed he made no effort to save himself.
