Kuhn became a prisoner of war of the Soviets after the 20 July plot. He led the Soviets to the hiding place of the documents in February 1945. In 1989, Soviet leader Mikhail Gorbachev presented these documents to then-German chancellor Dr. Helmut Kohl. The conspirators' motivations have been a matter of discussion for years in Germany since the war. Many thought the plotters wanted to kill Hitler in order to end the war and to avoid the loss of their privileges as professional officers and members of the nobility.
