The battle of Normandy programmed by the allies is based on a massive and rapid landing, which will destabilize by its audacity the German General Staff!
In a few hours, 150,000 Allied combatants will set foot on Norman soil on June 6, 1944.
Facing them, an equivalent number of German soldiers, but only a third of them are operational on this front. The German command was awaiting a landing in the Pas-de-Calais, at the narrowest point of the English Channel. It will take several days for the Germans to admit that the landing of Normandy was not a lure.
The first hours of the landing will be decisive.
The challenge for the Allied coalition will be to quickly break through the German defenses to broaden the front and resist enemy counter-offensives. The first weeks of June 1944 will be marked by terrible fights without any decisive advantage. Then, powerful actions of conquest and encirclement will be conducted, leading to the annihilation of the last German troops from the pocket of Falaise. This denouement will take place on August 21 near Chambois, in a place now known as the "death row".
The Battle of Normandy ends on September 12, 1944 with the liberation of Le Havre. 99 days after June 6th.
