Sunk on 17 February 1945 in the Skagerak in Oslofjord off Horten, in position 59.24N, 10.32E, by an air-laid mine in the British minefield Onions IV. 43 dead and 8 survivors.
In 1946 the Norwegian Navy partly salvaged the wreck of this boat and destroyed the remains on the seabed.
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in February 1945 but it was of course installed prior to that date. Read more about the Schnorchel and see list of fitted boats.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-1273 did not suffer any casualties (we know of) until the time of her loss.
