Normandy
Because of uncertainty in the German high command regarding Allied intentions after the D-Day landings, the 7th Army did most of the initial fighting in Normandy although it was later reinforced by the Panzer Group West. The 15th Army was kept at the Pas de Calais, expecting another landing by the Allies. By 18 June, the 7th Army had lost 97,000 men, including five generals. On 28 June, the army's commander, General Dollmann, died of a heart attack.
Under unrelenting Allied pressure, the 7th Army was slowly forced back through the hedgerow country in Normandy. Finally, in late July 1944, the 7th Army's weakened left wing was flattened by a massive Allied aerial bombardment and then assaulted and broken by the U.S. 1st Army. Armored exploitation of the rent in the front lines by U.S. units forced first a German retreat and then an unsuccessful counter-attack which ultimately culminated in the 7th Army being nearly wiped out in the Falaise Pocket.
Abandoning what remained of their heavy equipment, shattered remnants of the 7th Army escaped from the Falaise Pocket and retreated eastward to the German border. During the autumn of 1944, the 7th Army adopted a defensive posture in the Eifel region on the Belgian and Luxembourgian border while Hitler husbanded forces for a winter offensive on the Western Front.
