Stauffenberg, who had brought new dynamism to the sagging momentum of the opposition, wanted a strike against Hitler by mid-November. But who would carry it out? Colonel Stieff, approached by Stauffenberg in October 1943, declined. The attempt had to be postponed. Colonel Joachim Meichßner from the Wehrmacht operational staff
Bad luck continued to dog the plans. One such uniform display, in December 1943, had to be cancelled when the train carrying the new uniforms was hit in an air-raid and the uniforms destroyed. Before Bussche could be brought back for another attempt, he was badly wounded on the eastern front in January 1944, losing a leg and dropping out of consideration for Stauffenberg’s plans.56
Lieutenant Ewald Heinrich von Kleist, son of the Prussian landowner and longstanding critic of Hitler Ewald von Kleist-Schmenzin, expressed himself willing to take over.57 Everything was set for Hitler’s visit to a uniform display in mid-February. But the display was once again cancelled.58
Yet another chance arose when Rittmeister Eberhard von Breitenbuch, aide-de-camp to Field-Marshal Busch (Kluge’s successor as Commander-in-Chief of Army Group Centre) and already initiated in plans to eliminate Hitler, had the opportunity to accompany Busch to a military briefing at the Berghof on 11 March 1944. Breitenbuch was uncertain about an attempt with a bomb, but had declared himself ready to shoot Hitler in the head. His Browning pistol was in his trouser pocket, and ready to fire as soon as he came close to Hitler. But on this occasion, ADCs were not permitted in the briefing. Luck was still on Hitler’s side.59
Even Stauffenberg began to lose heart — especially once the western Allies had established a firm footing on the soil of France. The Gestapo by now had the scent of the opposition; a number of arrests of leading figures pointed to the intensifying danger.60 Would it not now be better to await the inevitable defeat? Would even a successful strike against Hitler be anything more than a largely empty gesture? Tresckow gave the answer: it was vital that the coup took place, that the outside world should see that there was a German resistance movement prepared at the cost of its members’ lives to topple such an unholy regime.61
A last opportunity presented itself. On 1 July 1944, now promoted to colonel, Stauffenberg was appointed Fromm’s chief of staff — in effect, his deputy. It provided him with what had been hitherto lacking: access to Hitler at military briefings related to the home army. He no longer needed look for someone to carry out the assassination. He could do it himself. That this was the only solution became more evident than ever when Stieff declined a second request from Stauffenberg to try to kill Hitler at the display of uniforms finally taking place at Klessheim on 7 July.62
The difficulty with Stauffenberg taking over the role of assassin was that he would be needed at the same time in Berlin to organize the coup from the headquarters of the reserve army.63 The double role meant that the chances of failure were thereby enhanced. It was far from ideal. But the risk had to be taken.
