In November 1942, Goerdeler made a secret and illegal visit to Smolensk using forged papers provided by Colonel Hans Oster to meet Field Marshal Günther von Kluge and Henning von Tresckow to gain their support for overthrowing Hitler. Both Kluge and Tresckow promised to arrest Hitler when he visited the Eastern front. Tresckow in particular was very favourably impressed with Goerdeler, whom he saw as a kindred spirit. Goerdeler returned to Berlin feeling assured about the future, and was most disappointed when he received a message from Kluge via General Beck stating he changed his mind about acting against the Nazi regime, and to include him out of any "putsch". Kluge's change of mind about attempting to overthrow Hitler was related to the "gifts" he had received from Hitler in the fall of 1942. On October 30, 1942 Kluge was the beneficiary of an enormous bribe from Hitler who mailed a letter of good wishes together with a huge cheque totaling 250,000 marks made out to him from the German treasury and a promise that whatever improving his estate might cost could be billed out to the German treasury. Hitler was unaware of Goerdeler's plotting, but had heard rumours that Kluge was unhappy with his leadership. After receiving another "gift" of 250,000 marks from Hitler later in November that was intended to buy his loyalty, it had the desired effect with Kluge's message to Goerdeler not to involve him in anti-Nazi plots.
