However, on 20 July 1944, Goerdeler's plan fell apart when Claus von Stauffenberg's attempt to kill Hitler at the Wolf's Lair in East Prussia failed. Bolz was arrested on 12 August 1944, and on 21 December, he was sentenced to death at the German "People's Court" ("Volksgerichtshof"). He was beheaded at Plötzensee Prison in Berlin on 23 January 1945.
