This map was dropped on German troops by the Allies shortly after the D-Day invasion of France in June 1944. The verso describes the Russian advances on the Eastern Front, the RAF and American bombing of Germany, and allied success in Italy, on the Southern Front. It concludes: “Catastrophe in the East; Catastrophe at Home; Catastrophe in the South; and Now with the Allied Landing in the West, the Fourth Front Has Opened.”
The map of the “Four-Front War” makes the point starkly, printed in red with dashed lines for the fronts in the East, South and West, and bomb symbols filling the German “Home Front.”
