Even after Admiral Dönitz ordered the war's end, German U-boat U-530 did not surrender. Instead, it traveled to Mar del Plata, Argentina, and eventually gave itself over to the Argentinian Navy. The suspicious thing about this craft is that the sub's captain, Otto Wermuth, refused to explain why it took them two months to get to Argentina, why they dismantled their own deck gun, why the crew had no identification, or why there was no log on the ship. Some speculate that their secrecy covered up the ferrying of high-ranking Nazis to South America, including Adolf Hitler himself.
