Galland's efforts with the fighter program results in the mobilization of all surviving Luftwaffe units in a co-ordinated assault against an Allied bomber raid of almost 2,600 aircraft in November 1944. The attack so severely cripples the bomber force that the Allies are forced to suspend the bombing campaign of Germany. The postponement buys Rommel more time to boost his forces for a major offensive through the Ardennes. Although the operation is codenamed "Wacht Am Rhein," von Reinhardt successfully proposes a change to "Fuchs Am Rhein" (Fox on the Rhine) to emphasize Rommel's role as the leader of the offensive. Heinz Guderian is also assigned to lead one of the two "panzerarmees" to be used in the operation, which aims to reach Antwerp.
