Without any further reinforcements in men or materiel, the Waffen-SS divisions could not stop the Allied advance. 1 SS "Leibstandarte " and 2 SS "Das Reich" took part in the failed Operation Lüttich in early August. The end came in mid August when the German Army was encircled and trapped in the Falaise pocket, including the 1 SS "Leibstandarte", 10 SS "Frundsberg" and 12 SS "Hitlerjugend" and the 17 SS "Götz von Berlichingen", while the 2 SS "Das Reich" and the 9 SS "Hohenstaufen" were ordered to attack Hill 262 from the outside in order to keep the gap open. By 22 August, the Falaise pocket had been closed, and all German forces west of the Allied lines were dead or in captivity. In the fighting around Hill 262 alone, casualties totalled 2,000 killed and 5,000 taken prisoner. The 12 SS "Hitlerjugend" had lost 94 per cent of its armour, nearly all of its artillery, and 70 per cent of its vehicles. The division had close to 20,000 men and 150 tanks before the campaign started, and was now reduced to 300 men and 10 tanks.
