Interned at Mar del Plata, Argentina on 17 August, 1945 after a
66-day submerged trip from Norway.
Surrendered to USA in Boston on 13 Nov, 1945. She was torpedoed
off Massachusetts on 13 Nov, 1946 during torpedo trials by USS
Surrender in Argentina in August, 1945The 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.
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.
