On 8 January, Hitler authorised Manteuffel to withdraw from the tip of the bulge, and on 15 January he gave up the whole enterprise and returned to Berlin. By the end of January the Germans were back where they had started. But the offensive had burned up the last of Rundstedt's reserves of manpower, equipment and fuel, and as a result neither the West Wall nor the Rhine could be properly defended. On 18 February, as the Allies entered Germany, Rundstedt issued an appeal to the German Army to resist the invader, urging the troops to "gather round the Führer to guard our people and our state from a destiny of horror." Hitler rewarded his loyalty with the Swords to his Knight's Cross. Despite fierce resistance in places, the Germans were forced back from the West Wall during February, and a series of Allied offensives, rolling from north to south, drove across the Rhineland towards the great river. On 2 March the Americans reached the Rhine near Düsseldorf. Rundstedt had been aware as early as September of the importance of the many bridges over the Rhine, and of the necessity of denying them to the enemy. He made careful plans for the bridges to be blown up if the enemy reached the Rhine. On 7 March, however, these plans failed when the Americans captured the Ludendorff Bridge at Remagen intact, and rapidly established a bridgehead on the eastern bank. This could hardly be blamed on Rundstedt, but he was the commander and Hitler needed a scapegoat.
