|Twelfth Army Group. Situation - 2400 HRS 6 JUNE 1944 HQ. FUSAG, 1944
The Second Front was finally launched on D-Day, June 6, 1944. The invasion's success was due in part to the deception plan that Churchill had outlined at Teheran. The Germans were convinced that the Normandy landings were only a feint and that the main assault was to come later from a phantom First United States Army Group (FUSAG) at the Pas des Calais. As this "HQ. FUSAG" map shows, documents with misleading headings were created. However, it shows the situation at D-Day's end fairly accurately, except that some Allied units are missing so that the Germans would think the assault was on a smaller scale.
