By the end of July, American forces had broken out of Normandy. As they swept east, the German Seventh Army was pinned by the Second Army and trapped in pockets around Falaise. The German formation was subsequently annihilated during the battle of the Falaise pocket. The Second Army then commenced a dash across France in parallel with the Americans on its right, and the Canadians on its left. During the interim, I Corps was transferred from Second Army's control, and assigned to the First Canadian Army. Due to the heavy casualties sustained by the army during the Normandy campaign, the 59th (Staffordshire) Infantry Division was disbanded in August 1944 to make up for the infantry deficit.
