When Joseph Goebbels was informed in September 1943 that the German Army had to withdraw from the Katyn area, he wrote a prediction in his diary. His entry for 29 September 1943 reads: "Unfortunately we have had to give up Katyn. The Bolsheviks undoubtedly will soon 'find' that we shot 12,000 Polish officers. That episode is one that is going to cause us quite a little trouble in the future. The Soviets are undoubtedly going to make it their business to discover as many mass graves as possible and then blame it on us".
