Personal information
Previously in the war Schäffer had made 4 patrols as watch officer on the U-445. He then took command of the small boat U-148. (Blair, Clay. 1998. Hitler's U-boat War)
With his U-977 he made the very famous and no doubt hardship-filled trip to Argentina when Germany announced its surrender. He made sure not to fire any torpedoes as to not being accused of sinking any ships after the cease-fire orders.
After the war he wrote the book U-boat 977 about this patrol and all the crazy rumors related to it.
