By 21 December the Germans had surrounded Bastogne, which was defended by the 101st Airborne Division and Combat Command B of the 10th Armored Division. Conditions inside the town were tough. Food was scarce, and by 22 December artillery ammunition was restricted to 10 rounds per gun per day. The weather cleared the next day, however, and supplies (ammunition) were dropped over four of the next five days. Despite German attacks, the town held. The German commander, Lt. Gen. Heinrich Freiherr von Lüttwitz, requested Bastogne's surrender. When Brig. Gen. Anthony McAuliffe was told of the Nazi demand that he surrender, he refused.
