Attacks on U-509 during this patrol

11 Nov 1942
While operating against the Allied Torch landings off Morocco the boat operated for three days in waters less than 200 ft (61m) deep, and Witte reported being constantly bombed and depth charged by Allied surface vessels and aircraft. Damage forced her to move to deeper water and then to France. (Sources: Blair, vol 2, page 108)
