in Argentina, which had a large German community. Schäffer offered the married crewmen the option of going ashore in Europe. Sixteen chose to do so and were landed from dinghies on Holsnøy island near Bergen on 10 May . U-977 then sailed to Argentina. Schäffer's version of the voyage states that from 10 May to 14 July 1945 she made a continuous submerged Schnorchel passage, "at 66 days the second longest in the war [sic - Germany had surrendered] (after 's 68 days)". The U.S. Navy (USN) interrogated the crew and issued a report on 19 September 1945. The report does not mention a 66-day submerged voyage, but states that U-977 "made for the Iceland Passage on course 300° [that is, northwest by west] diving once on sighting a plane and once on sighting a ship; she was also DF'd many times late in May". (This could also mean traveling at snorkel depth and then diving on contact; possible translation errors during interrogations.) According to the Navy report, the submarine stopped in the Cape Verde Islands for a short break, then completed the trip traveling on the surface using one engine. Crossing the equator on 23 July, she arrived in Mar del Plata, Argentina on 17 August after 99 days at sea from Bergen and a voyage of 14,157 km (7,644 nmi, 8,797 mi). These points agree with Schäffer's report that he stopped at Cape Verde Islands for a short break and crossed the equator on 23 or 24 July 1945. Schäffer said that, after the short Cape Verde break, they completed the rest of the trip to Mar del Plata alternately on the surface and submerged. After surrendering to the Argentine authorities, as had happened to the crew of U-530, they were extradited to the US where they responded to the charge of having torpedoed the cruiser Bahia, and then to the UK, where they faced accusations that they had landed Nazi leaders in Argentina before surrendering. Schäffer was released in 1947. U-977 like U-530 was seized by the US Navy, and sunk during naval firing exercises, in its case in 1946, when it was used as a target. In the arts Schäffer later wrote a book: U-977 – 66 Tage unter Wasser ("U-977 – 66 Days Under Water"), the first postwar memoir by a former U-boat officer. It was published in 1952, and was translated into English under
