Attacks on this boat

11 Nov 1942
While operating against the Allied Torch landings off Morocco the boat operated for 3 days in waters less than 200 feet deep and Witte reported being constantly bombed and depth charged by Allied surface vessels and aircraft. The boat developed some damages forcing her to abort to deeper water and then to France. (Sources: Blair, vol 2, page 108)

10 Feb 1943
After sinking the British vessel Queen Anne, the boat was attacked by the ASW trawler St. Zeno with gunfire and seven depth charges but was not damaged and slipped away. (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.
