Lanz stated that he would have then arrested Hitler, and in the event of resistance, Strachwitz's tanks would have shot and killed the entire delegation. Hitler cancelled the visit and the plan was dropped.[70] Author Röll casts doubt on this account citing that Strachwitz's cousin, Rudolf Christoph Freiherr von Gersdorff, who attempted to assassinate Hitler in 1943, had recounted that Strachwitz had expressed the belief to him several times that killing Hitler would have constituted murder. Röll concludes that Strachwitz was too much a Prussian officer to consider assassinating Hitler.[71]
