 However, the events of the war moved too quickly for the "Bundschuh" plotters, and Buchardt had to retreat 200 miles to the Austrian-German border.Shortly after the war, he was captured by American troops and transferred to the British, who held him at the POW camp in Rimini.During his detention, Buchardt produced a document entitled "The Handling of the Russian Problem during the Period of the Nazi Regime in Germany", which detailed his espionage activities in Eastern Europe and emphasized the importance of native collaborators in SS operations.
