General notes on this boat

The loss of U-576
On 15 July 1942 convoy KS 520, proceeding from Norfolk to Key West, Fla encountered U-576 off Cape Hatteras. The U-boat sank one ship and damaged two others before she was sunk by shells from the stern gun of the US motor merchant Unicoi (Master J. Muhle) and four depth charges from two OS2U Kingfisher aircraft (pilots Ens. Frank C. Lewis and Ens. Charles D. Webb) of VS-9 based at MCAS Cherry Point, NC, part of the Carrier Air Group 9 and on temporary inshore patrol duty with Eastern Sea Frontier. Many reference sources claim Unicoi rammed U-576, but this can not be confirmed from original reports.

21 Oct 2014. NOAA has reported that U-576 (Heinicke) has been discovered together with her last victim, the motor merchant Bluefields. The wrecks are less than 250 yards apart. U-576 has accordingly been added to our U-boats discovered since their loss page.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-576 did not suffer any casualties (we know of) until the time of her loss.
