Incriminating evidence left by the conspirators of the 20 July plot against Hitler was discovered at Maybach II in a safe at Zossen. Among the documents reportedly uncovered were excerpts from the diary of Wilhelm Canaris, conspiratorial correspondence between Abwehr agents, information on the secret negotiations between the Vatican and members of the originally planned (1938) coup d’état, and data on the resistance activities of Lutheran minister Dietrich Bonhoeffer.[7]
