The card to be played was a swift and decisive military strike aimed at inflicting such a mighty blow on the western Allies that they would lose the appetite for continuing the fight. This would lead to the breakup of what was perceived as an unnatural coalition of forces facing Germany. Hitler’s own characteristic thinking was plainly outlined in his address to his division commanders four days before the beginning of the offensive. ‘Wars are finally decided’, he asserted, ‘by the recognition on one side or the other that the war can’t be won any more. Thus, the most important task is to bring the enemy to this realization.’ Even when forced back on the defensive, ‘ruthless strikes’ had the effect of showing the enemy that he had not won, and that the war would continue, ‘that no matter what he might do, he can never count on a capitulation—never, ever’. Under the impact of severe setbacks and recognition that success was unattainable, the enemy’s ‘nerve will break in the end’. And Germany’s enemy was a coalition of ‘the greatest extremes that can be imagined in this world: ultra-capitalist states on one side and ultra-Marxist states on the other; on one side a dying world empire, Britain, and on the other side a colony seeking an inheritance, the USA’. It was ripe for collapse if a blow of sufficient power could be landed. ‘If a few heavy strikes were to succeed here, this artificially maintained united front could collapse at any moment with a huge clap of thunder.’2
The first deliberations for an offensive in the west had taken place at precisely the time of German crisis on that front—during the collapse in Normandy in mid-August. By mid-September the decision for the offensive, given the code-name ‘Watch on the Rhine’ (later changed to ‘Autumn Mist’), was taken. Utmost secrecy was of the essence. Only a few in the High Command of the Wehrmacht and among the regime’s leaders were in the know. Even Field-Marshal von Rundstedt, restored as Commander-in-Chief West on 5 September, was told only in late October of the aims of the operation.3
Jodl’s plans for the attack went through a number of variations before Hitler’s order to go ahead was given on 10 November. Then the intended launch of the offensive in late November had to be postponed several times because of equipment shortages and unseasonal good weather—the attack was depending on poor weather to ground enemy aircraft—before the final date was set at 16 December. The military goal was to strike, as in 1940, through the wooded Ardennes in the gap between the American and British forces, advancing rapidly to take Antwerp and, in tandem with German divisions attacking towards the south from Holland, cutting the enemy lines of communication with the rear, encircling and destroying the British 21st Army Group and the 9th and 1st US Armies in a ‘new Dunkirk’. It would, according to Hitler’s directive for the operation, bring ‘the decisive turn in the western campaign and therefore perhaps of the entire war’.4The situation, on the eastern as well as the western front, had deteriorated drastically since the idea for the offensive had initially been conceived. On the eastern front, the Soviet incursion into East Prussia had, it is true, been repelled but the most acutely threatened area had meanwhile become Hungary, a crucial source of oil and other raw materials. German troops were engaged there in bitter attritional fighting throughout the autumn in fending off the Red Army’s attempt to take Budapest, ordered by Stalin at the end of October.5
In the west, meanwhile, American troops stood on German soil in the Aachen area. After taking the city in late October, their advance during the following weeks in the densely wooded hills beyond the
