Attacks on this day


U-382. The boat suffered severe damage from depth charging by escorts of convoy UC 1, and was forced to return to France. Date of attack is approximate. (Blair, vol 2, page 198)

U-569. Depth charges from the escorts of convoy UC 1 caused so much damage that the boat was forced to return to France. Date is approximate. (Blair, vol 2, page 198)

U-371. At 14.06 hrs the boat was located by HMS Felixstowe after the sinking of Fintra, approx. 30 nautical miles ENE of Algiers. The minesweeper dropped 25 depth charges in six attacks between 14.10 and 15.08 hrs and observed air bubbles rising to the surface after the second and sixth passes. Her commander considered the U-boat sunk, but U-371 was undamaged and escaped by moving closer to the coast and heading east. (ADM 199/1784)
