The German Seventh Army was part of Army Group B during the Battle of Normandy. It was commanded by SS Obergruppenführer Paul Hausser, former commander of II SS Panzer Corps. The Seventh Army did most of the fighting during Normandy and its only help was the new Fifth Panzer Army. The Fifteenth Army was stationed at the Pas de Calais for an invasion. The Seventh Army was nearly wiped out in the Falaise Pocket. During Operation Market-Garden, the Seventh Army was in the Ardennes on the Belgian-Luxembourg border for Hitler's offensive on the Western Front. During the Battle of the Bulge, it protected Fifth Panzer Army but it was almost wiped out again. After Remagen, when the Allies surrounded the Ruhr pocket, the Seventh Army surrendered to the US First Army.
