like the go signal for the VII Corps and an attack to advance its western wing. Because the wire line to the 2d Armored command post had gone out, Palmer sent his aide with a message for Collins giving his own optimistic interpretation of the conversation with Kean.
The aide had just departed when Kean called again. On further reflection, he said (perhaps Kean had caught a tone of exultation in Palmer's voice), he doubted whether Palmer had understood him correctly. Then came the cold water douche: "Now get this. I'm only going to say it once. Roll with the punch." Palmer's glance flicked over the map, this time to the north; there, thirty miles to the rear of the villages he had selected earlier were the towns of Andenne and Huy. Palmer remembers that this was the only moment in the war when he was "ill with disapproval."
Out went a second messenger with an explanation of Palmer's mistake and an urgent request for Collins to come home. Collins, who had received the first message at Harmon's command post, was just giving the finishing touches to an attack plan for the entire 2d Armored when the second messenger appeared. Telling Harmon to "hold everything" but making clear that the 2d Armored was to go ahead with plans for the attack on Christmas morning, Collins hurried back to his own headquarters. He arrived there about 1830 but nothing more could be done until a liaison officer, promised by Kean, came in from the First Army.
Two hours later the First Army staff officer (Col. R. F. Akers) appeared and confirmed the bad news. Montgomery and Hodges had agreed to shorten the First Army line in order to halt the German advance. The VII corps, therefore, was to go on the defensive and its commander was "authorized" on his own judgment to drop back to the line Andenne-Hotton-Manhay. In any case the VII Corps was to retain a firm contact with the XVIII Airborne Corps, which that evening was withdrawing to the Manhay position.
Although General Collins courteously asked the senior members of his corps staff to give their opinions on the action now to be taken by the corps, neither he nor any of his officers considered giving over the attack planned for the 2d Armored. During the day Harmon's tanks had inflicted very severe damage on the German columns; the 84th Division had experienced some reverses but seemed to be holding its own. On balance the picture as seen from the VII Corps' point of view was far less gloomy than that apparently prevailing in higher headquarters. Collins recognized that a retrograde move would strengthen the defenses of Huy and Liege. He also knew that such a move would expose Namur and the major Meuse crossings south of that city, for example, those at Dinant. The final decision, made by the corps commander himself, probably could have been predicted: on 25 December the 2d Armored Division would advance as planned; the corps then would continue with limited objective attacks to break up any dangerous concentration of enemy forces on its front. 
The boundary between the VII Corps and the XVIII Airborne Corps lay generally along the direct road from Bastogne to Liege, but this was essen-
 General Collins had a detailed memorandum on these events prepared by his staff and later kindly provided a photostat copy to the author.
