Armored Division. General Gaffey's letter of instructions to General Dager, commanding CCB, said, " . . . you will drive in, relieve the force, and *proceed* [italics supplied] from Bastogne to the NE...." The impression held by 4th Armored commanders and staff was that an independent tank column could cut its way through to the city ("at any time," said Dager), but that the opening of a corridor equivalent to the width of the road bed would be self-sealing once the thin-skinned or light armored columns started north to resupply and reinforce the heavy armor which reached Bastogne. The mission set the 4th Armored would require the co-ordinated efforts of the entire division, nor could it be fulfilled by a dramatic ride to the rescue of the Bastogne garrison, although this may have been what General Patton had in mind.

The Third Army commander, veteran tanker, himself prescribed the tactics to be used by Gaffey and the 4th Armored. The attack should lead off with the tanks, artillery, tank destroyers, and armored engineers in the van. The main body of armored infantry should be kept back. When stiff resistance was encountered, envelopment tactics should be used: no close-in envelopment should be attempted; all envelopments should be started a mile or a mile and a half mile back and be made at right angles. Patton, whose experience against the Panther tank during the Lorraine campaign had made him keenly aware of its superiority over the American Sherman in gun and armor, ordered that the new, modified Sherman with heavier armor (the so-called Jumbo) should be put in the lead when available. But there were very few of the Jumbos in the Third Army.

At 0600 on 22 December (H-hour for the III Corps counterattack) two combat commands stood ready behind a line of departure which stretched from Habay-la-Neuve east to Niedercolpach. General Gaffey planned to send CCA and CCB into the attack abreast, CCA working along the main Arlon-Bastogne road while CCB advanced on secondary roads to the west. In effect the two commands would be traversing parallel ridge lines. Although the full extent of damage done the roads and bridges during the VIII Corps withdrawal was not yet clear, it was known that the Sure bridges at Martelange had been blown. In the event that CCA was delayed unduly at the Sure crossing CCB might be switched east and take the lead on the main road. In any case CCB was scheduled to lead the 4th Armored Division into Bastogne.

On the right CCA (General Earnest) moved out behind A Troop of the 25th Cavalry Squadron in two task forces of battalion size. Visibility was poor, the ground was snow-covered, but the tracked vehicles were able to move without difficulty over the frozen terrain-without difficulty, that is, until the eastern task force commenced to encounter demolitions executed earlier by the VIII Corps engineers. The upshot was that both task forces converged on the main Arlon road and proceeded as a single column. Near Martelange a large crater delayed the column for some time. Shortly after noon it was bridged and the advance guard became embroiled in a fire fight with a rifle company of the 15th Regiment (5th Parachute Division) guarding the bridges, now demolished, at Martelange.
