At the age of 19, he fled East Germany and began a month-long trek to West Germany to escape the East German state. During this trek, part of his finger was lost but surgically reattached. Kretschmann crossed four borders (Hungary, Yugoslavia, Austria) with nothing other than his passport and the equivalent of $100 in his possession.
