have considerable effect on the conduct of the ensuing battle. The Opposing Grand Tactics
By Christmas Day it was apparent in both the Allied and German headquarters that the Ardennes battle had entered a new phase and that events now afoot required a fresh look at the grand tactics to be applied as the year drew to its close.
The Allied commanders had from the very first agreed in principle that the ultimate objective was to seize the initiative, erase the German salient, and set an offensive in motion to cross the Rhine. There was division in the Allied camp, however, as to when a counteroffensive should be launched and where it should strike into the salient. Beyond this, of course, lay the old argument as to whether the final attack across the Rhine should be on a wide or narrow front, in the British or in the American sector. 
On 25 December the commanders of the two army groups whose troops faced the Germans in the Ardennes met at Montgomery's Belgian headquarters. General Bradley, whose divisions already were counterattacking, felt that the German drive had lost its momentum and that now was the moment to lash back at the attackers, from the north as well as the south. Field Marshal Montgomery was a good deal less optimistic. In his view the enemy still retained the capability to breach the First Army front (a view shared by the First Army G-2, who was concerned with two fresh
German armored divisions believed to be moving into the Malmedy sector); the American infantry divisions were woefully understrength; tank losses had been very high; in sum, as Montgomery saw it, the First Army was very tired and incapable of offensive action. Bradley was distressed by Montgomery's attitude and the very next day wrote a personal letter to his old friend, the First Army commander, carefully underscoring the field marshal's authority over Hodges' army but making crystal clear that he, Bradley, did not view the situation "in as grave a light as Marshal Montgomery." As Bradley saw it the German losses had been very high and "if we could seize the initiative, I believe he would have to get out in a hurry." The advice to Hodges, then, was to study the battle with an eye to pushing the enemy back "as soon as the situation seems to warrant."
Perhaps, after Bradley's visit, the field marshal felt that he should set the record straight at SHAEF. After a long visit with Hodges on the 26th, he sent a message to Eisenhower saying that "at present" he could not pass to the offensive, that the west flank of the First Army continued under pressure, and that more troops would be needed to wrest the initiative from the Germans. At the moment, however, the Supreme Commander was concerned more with
 This controversy as to Allied strategy is well treated in Pogue, The Supreme Command, pp. 312-17. Montgomery's strategy has had a number of defenders, but in the main they have produced more heat than light. One of the ablest is Reginald William Thompson whose The Battle for the Rhineland (London: Hutchinson, 1958) advances the thesis that Montgomery's attitude throughout the Ardennes campaign was governed by the military principle of the "maintenance of the objective," that is, the retention of forces (British and Canadian) in a posture which would permit a rapid resumption of the battle for the Rhineland.
