Eventually, the conspirators came to rely more on the Reserve Army in Berlin and other districts to stage a coup against the German government. Olbricht now put forward a new strategy for staging a coup against Hitler. The Reserve Army had an operational plan called Operation "Walküre" (Valkyrie), which was to be used in the event that the disruption caused by the Allied bombing of German cities caused a breakdown in law and order, or an uprising by the millions of slave laborers from occupied countries now being used in German factories. Olbricht suggested 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.
