There were times during World War I and World War II when the German Unterseeboot or U-boat was the most feared submarine in the world. Blockading ports and attacking military, cargo and even passenger ships, the Nazi U-boats of WWII were terrifying by reputation as well as by actually deadly confrontations. The development of radar and sonar and the cracking of Nazi secret codes with the Enigma machine finally ended the reign of the U-boats, but there have been rumors since the end of World War II of a few being used for nefarious purposes – to smuggle war loot and Nazi leaders out of the country to South America. One such rumor has Adolf Hitler himself escaping in U-boat to Argentina – despite the general consensus that he killed himself on April 30, 1945, in the Führerbunker in Berlin. That rumor is back in the news this week with the announcement that wreckage found recently off the coast of Argentia is definitely a U-boat. Is it THE U-boat?
