General notes on this boat

4 Sep 1945. The last German unit surrendered. It was weather station 'Haudegen' (buccaneer) on Spitzbergen (now known as Svalbard), landed there by U-307 on 28 September 1944.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-307 did not suffer any casualties (we know of) until the time of her loss.
