Attacks on this boat and other events
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)
10 Feb 1943
After sinking the British merchantman Queen Anne, U-509 was fired on by ASW trawler HMS St. Zeno, which also dropped seven depth charges before the boat managed to escape. No damage. (Sources: Blair, vol 2, page 229)
2 recorded attacks on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-509 did not suffer any casualties (we know of) until the time of her loss.
