1 July 1946

During the Nuremberg trial, the Soviet prosecutors make an unsuccessful attempt, as it will later turn out, to charge the German officers Colonel Friedrich Ahrens and Lieutenant Reinhard von Eichborn from the 537th communications regiment of the former Army Group „Centre” with responsibility for the murder of Polish prisoners of war in the Katyn Forest.

On that day, in his account of the Nuremberg trial, ‘Dziennik Polski i Dziennik Żołnierza’ revealed the dropping off of the report on the massacre of Polish officers in the Katyn Forest to Dr. Otto Kranzbuchler (Admiral Doenitz’s defender), but also the fact that this document was not accepted by a British judge, Sir Geoffrey Lawrence, President of the International Military Tribunal in Nuremberg, as having no publisher’s name.

The London pamphlet ‘Report on the Massacre of Polish Officers on the Katyn Wood’ will go down in history as a document whose inclusion in evidence would not save the lives of the judged leaders of the Third Reich, but would certainly drive a wedge between the Allies. And perhaps it would led to the outbreak of World War III, which for two years had been precisely prepared on the orders of Winston Churchill.
