Attacks on this day


U-123. While attacking convoy OB 244 (4 ships sunk) the boat was seriously damaged by a collision with an unidentified object (probably a convoy vessel) and had to return to France for 50 days of repairs. (Blair, vol 1, page 208)

U-100. After a successful attack on convoy SC 11 in the Atlantic west of Ireland, star shells from a destroyer forced U-100 to dive. The depth charging that then followed disabled the hydrophones. (Ritschel)


The targets of the attacks by British frigates HMS Bazely, HMS Blackwood and HMS Drury on 23 Nov. 1943 in position 42.40N, 20.73W, formerly credited with the destruction of U-648, were in fact U-424, U-714 and U-843, all of which escaped unscathed. (1998-01-01, Axel Niestle)
