Following the Normandy landings, Rommel rushed Heeresgruppe B reserves towards the coast in order to crush the bridgehead and drive the Allied forces back into the sea. One of these armored reserves was the newly created 12. SS-Panzer-Division Hitlerjugend. Extremely well equipped and at near full strength by mid-1944 standards, it was seen as an extremely capable formation. As Allied forces flooded inland from the beaches, 12. SS-Panzer-Division attempted to capture and hold the battlefield initiative. However, despite this German armoured division’s best efforts, it would be bludgeoned and driven back in a series of offensive set-piece operations by the British Second Army, supported by massive artillery programs and RAF air strikes. As a result, the division failed to succeed in its new defensive role, and was slowly weakened by attrition, reducing its combat arms regiments to a weakened Kampfgruppe by mid-July. This volume focuses on the fighting between 11 June and 12 July: the Cristot triangle, the Parc de Boislonde, Fontenay-le-Pesnel, Operation Epsom and the main events of the Battle of the Odon, Operation Windsor and the attack on Carpiquet airfield, and finally the massive Anglo-Canadian assault on Caen, Operation Charnwood. A detailed set of appendices will analyze German personnel, equipment, and armored losses during the battles, and losses inflicted on the Allies.
