For his participation in the 20 July 1944 plot, Theodor Strünck was arrested on 1 August, dishonourably discharged from the army on 24 August as part of the "Ehrenhof" (so that the Reichskriegsgericht or Reich Courts Martial would no longer have control of his sentencing), and on 10 October condemned to death by the People's Court under its president Roland Freisler. He was then imprisoned in Flossenbürg concentration camp, where he, Dietrich Bonhoeffer, Wilhelm Canaris, Ludwig Gehre, Hans Oster and Karl Sack were executed together by hanging on 9 April 1945.
