General notes on this boat

10 May 1945. On 10 May, 1945 U-977, in Norwegian waters when Germany surrendered, put ashore those men who did not wish to accompany the rest of the crew on a desperate voyage to Argentina.

17 Aug 1945.

Surrender in Argentina in August, 1945

The boat left Kristiansand, Norway on 2 May, 1945 for a combat patrol in the English Channel. When Germany surrendered a few days later the boat was outbound in Norwegian waters. After deciding to head for Argentina Schäffer gave the married men on board the chance to go to shore. Roughly a third of the crew, 16 men, opted for the shore and were put on land on 10 May near Holsenöy in dinghies. They all ended up in British hands. U-977 then sailed for Argentina; from May 10 to July 14 the voyage was a 66-day continuous submerged Schnorchel run, the second longest in the war (after U-978's 68 days).

The journey was extremely difficult for the crew and many were apparently on the edge of a nervous breakdown. The boat stopped in Cape Verde Islands for a short swim break and then headed south on the surface using one diesel. Crossing the equator on July 23 she arrived in Mar del Plata, Argentina on 17 August for a total patrol length of 108 days.

The commander, Heinz Schäffer, published a book in 1952 called U-boat 977 about his journey.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus in February 1945. 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-977 did not suffer any casualties (we know of) until the time of her loss.
