The sinking of U-404
At 1107hrs the boat was located following radar contact by a US B-24 Liberator (4th A/S Sqn USAAF/Y, pilot Maj Stephen McElroy), but on attacking the depth charges failed to release. The aircraft waited for the boat to resurface and attacked again at 1517hrs. Despite a 20mm shell detonating inside the cockpit (without hurting anyone), the pilot dropped eight depth charges into the boats diving point. Flak damage to the radio and one engine then forced the aircraft to return to base. Another US Liberator (4th A/S Sqn USAAF/N, pilot 1Lt Arthur J. Hammer) then attacked U-404 twice after she surfaced again at 1745hrs. Flak damage also forced this aircraft to return to base, this time to one engine, the tail and the fuselage. The last attack was observed by a third Liberator, British BZ781 (224 Sqn RAF/W, pilot F/O R.V. Sweeny), which this time attacked and sank the boat. Yet again, one engine was hit by flak, and the plane barely made it back to base after jettisoning all guns and loose equipment. (Sources: Franks/Zimmerman)
