Attacks on U-642 during this patrol
9 Jul 1943
Aircraft attack, aircraft shot down:
British Catalina flying boat FP155 (210 Sqn RAF/F, pilot F/L D.M. Ryan)
1340hrs, 250 miles west of Lisbon, inbound: the port side of the aircraft was hit by flak during the attack run, damaging the wing, engine and a fuel tank and wounding the bow gunner. Due to this damage, only the three depth charges on the starboard side were dropped, but did not damage U-642, which crash-dived, and thus failed to observe the burning Catalina ditch shortly afterwards. Two aircrew died in the crash and another died the next day from a heart attack. Seven survivors were rescued four days later by HMS Swale and taken to Casablanca.
