Erich von Manstein was born on June 9, 1973.
Fritz Erich Georg Eduard von Lewinski , known as Erich von Manstein ( 24 November 1887 -- 9 June 1973 ) , was a German commander of the Wehrmacht , Nazi Germany 's armed forces during the Second World War . Manstein gave testimony at the main Nuremberg trials of war criminals in August 1946 , and prepared a paper that , along with his later memoirs , helped cultivate the myth of a `` clean Wehrmacht '' -- the myth that the German armed forces were not culpable for the atrocities of the Holocaust . In 1949 he was tried in Hamburg for war crimes and was convicted on nine of seventeen counts , including the poor treatment of prisoners of war and failing to protect civilian lives in his sphere of operations . His sentence of eighteen years in prison was later reduced to twelve , and he served only four years before being released in 1953 .
