of the division's tanks broke down during its movement to Normandy. The division's armored forces would be reinforced by the newly attached 102nd SS Heavy Panzer Battalion. This would provide Hohenstaufen with 127 additional combat vehicles including 79 Panther tanks. The original plan for Hohenstaufen to attack towards the Allied beachhead was made impossible by a British offensive to take Caen. The II SS Panzer Corps was instead put into the line to support the weakened forces defending Caen, where Hohenstaufen suffered 1,891 casualties. On 10 July, the division was pulled back into reserve, to be replaced by the 277th Infantry Division. The division's depleted Panzergrenadier regiments were eventually merged to form Panzergrenadier Regiment Hohenstaufen. The division saw much action defending against British armour during Operation Goodwood. During Operation Jupiter Hohenstaufen destroyed 58 British tanks with many of them being Churchill tanks. After the launch of the Canadian Operation Totalize, Hohenstaufen avoided encirclement in the Falaise pocket and kept the narrow escape route from this pocket open. By 21 August, the Battle of Normandy was over, and the German forces were in full retreat. Obersturmbannführer Walter Harzer was placed in command of the division. It fought several rearguard actions during the retreat through France and Belgium and in early September 1944, the exhausted formation was pulled out of the line for rest and refit near the Dutch city of Arnhem. By this time, Hohenstaufen was down to approximately 7,000 men, from 15,900 at the end of June. Arnhem Upon arriving in the Arnhem area, the majority of the remaining armoured vehicles were loaded onto trains in preparation for transport to repair depots in Germany. On Sunday, 17 September 1944, the Allies launched Operation Market-Garden, and the division fought in the Battle of Arnhem. The British 1st Airborne Division was dropped in Oosterbeek, to the west of Arnhem. Only the division's reconnaissance battalion, equipped mostly with wheeled and half tracked vehicles, was ready for action. Bittrich ordered Hohenstaufen to occupy Arnhem and secure a vital metal girder bridge (later torn down, rebuilt in concrete and named John Frost Bridge). The division encountered stiff resistance from the British Rote Teufeln (Eng. "Red Devils") 1st Airborne Division. The Reconnaissance Battalion, a 40-vehicle unit commanded by Hauptsturmführer Viktor Eberhard Gräbner, was sent south over the bridge to scout the area around Nijmegen. The bridge had already been captured by the Germans. Meanwhile, Colonel John
