that this plan could be used to mobilize the Reserve Army to take control of German cities, disarm the SS and arrest the Nazi leadership once Hitler had been assassinated. During August and September 1943, Tresckow took extended sick leave in Berlin to draft the "revised" Valkyrie plan with fine details and precise timetables. Revised orders and additional proclamations that would pin the blame for the uprising on the Nazi party were typed by Tresckow's wife, Erika, and his secretary, Countess Margarete von Oven, who wore gloves so as not to leave fingerprints. These 1943 papers were recovered by the Soviets after the war and finally published in 2007, showing Tresckow's central role in the conspiracy and the idealistic motivations of the resistance group at that time. Knowledge of the Jewish Holocaust was a major impetus for many officers involved. But when Tresckow was assigned to command of a battalion on the Eastern Front in October 1943, he was no longer in position to actively plan or effect the coup. Even his promotion a month later to Chief of Staff of the Second Army did not bring him much closer. To gain access to Hitler, he proposed to his old comrade General Rudolf Schmundt, Hitler's chief adjutant and Army personnel chief, to create a new department of psychological and political warfare to evaluate data and make reports directly to the Führer. Schmundt, who was still well disposed toward his old friend but suspected that Tresckow disapproved of the Führer, quietly let the matter drop. Tresckow also applied to become General Adolf Heusinger's delegate in the Army High Command (OKH) during the latter's two-month leave, which would also give him access to Hitler's meetings, but Heusinger, who was earlier approached by conspirators, rejected it apparently for the same reason. Colonel Claus Schenk Graf von Stauffenberg, who met Tresckow in August 1943 and worked together on revising Operation Valkyrie, took the responsibility for planning and implementing Hitler's assassination. By the time Stauffenberg was appointed Chief of Staff of the Reserve Army and was ready to carry out the assassination attempt, the Allies had already landed in Normandy. When Stauffenberg sent a message to Tresckow through Lehndorff to ask whether there was any point in making the attempt since there was no practical purpose to be served, Tresckow urged him not only to attempt the assassination but to go ahead with the coup
