Attacks on this day


U-331. The boat fought a gun duel with 3 British landing craft off Sidi Barrani and damaged HMS TLC-18 (A 18), but was itself slightly damaged. Two men of the gun crew were wounded, one of them mortally. [Bootsmann Hans Gerstenich]


U-159. 14.41 hrs, west of Cape Town: an SAAF Ventura bomber dropped three depth charges shortly after the boat crash dived. Only minor damage was caused, but U-159 was forced to give up her chase of a freighter sighted earlier.

U-172. At 13.01 hours, the boat was at periscope depth just after sinking the Orcades when an aircraft dropped three depth charges. No damage was caused, but U-172 had to leave the area submerged without questioning the survivors.


U-584. One man was lost overboard in the mid Atlantic south of Iceland. (Thus only 52 men were aboard when the boat was sunk 3 weeks later, rather than 53 as given in most sources).
