Drawing for the first time on Polish, German and Soviet sources, this talk explores the history of Germany's invasion of Poland in September 1939.
Did Britain and France assist their Polish ally to the best of their abilities when the German armies crossed the border on 1 September 1939?
While they went to war with Germany, why did they not declare war on the Soviet Union when its troops invaded Poland from the east later in the month?
And if the violation of Poland had been the reason to go to war in 1939, how could the Western Allies justify handing over the country on a plate to Stalin in 1945?
Roger will examine the broad outline of the campaign, its characteristics, its mythology and explain why it does not receive the attention that it should.
