• South African bomber pilot Flying Officer Lloyd Trigg attacked the German submarine U-468 in the South Atlantic off Senegal. On the first pass the submarine's anti-aircraft weapons seriously damaged the bomber. Instead of attempting a water landing, Trigg conducted a second attack run. As the bomber released depth charges, the Liberator aircraft was hit again and crashed into the sea 300 yards from the stricken submarine which also went down. Trigg and his entire crew all perished and only seven German sailors were rescued. Based on German survivor accounts, a report would later be filed detailing the gallant pilot's courage which led to the award of a posthumous Victoria Cross. ww2dbase [AC]
