The end of the second day of battle found the British Command faced with a difficult problem, and we have the Field-Marshal's own lucid analysis of the alternative courses open, and as to the reasons which prompted his decision. The capture of Cambrai had never been the goal of the operations, though a cavalry raid which would have disorganised the communications through that town had at one time seemed possible. A turning of the line to the south with the co-operation of some French divisions which were ready upon the spot, was part of the original conception, and was baulked by the insufficient hold established upon the farther side of the Canal de l'Escaut. But the central idea had been the capture of the high ground of Bourlon Hill and Wood for with this in British possession a considerable stretch of the defensive German line would lie open to observed artillery fire, and its retention would probably mean a fresh withdrawal to the east. It had been hoped that the goal would have been attained within forty-eight hours, but this time had elapsed and the assailants were at the bottom instead of the summit of the hill, with a resistance in front which was continually growing more obstinate. What was to be done? The troops could not remain where they were, for the Bourlon Hill overlooked their position. They must carry it or retire. There was something to be said for the latter policy, as the Flesquières Ridge could be held and the capture of 10,000 prisoners and over 100 guns had already made the victory a notable one, while the casualties in two days were only 9000. On the other hand, while there is a chance of achieving a full decision it is hard to abandon an effort; reinforcements were coming up, and the situation in Italy demanded a supreme effort upon the Western front. With all these considerations in his mind the Field-Marshal determined to carry on.
November 22 was spent in consolidating the ground gained, in bringing up reinforcements, and in resting the battle-weary divisions. There was no advance upon the part of the British during the day, but about one o'clock in the afternoon the Germans, by a sudden impetuous attack, regained the village of Fontaine and pushed back the Fifty-first Division in this quarter. No immediate effort was made to regain it, as this would be part of the general operations when the new line of attack was ready to advance. Earlier in the day the Germans had thrown themselves upon the front of the Sixty-second, driving back its front line, the 2/6th and 2/8th West Yorkshires, to the Bapaume-Cambrai Road, but the Yorkshiremen shook themselves together, advanced once more, and regained the lost ground with the help of the 2/4th York and Lancasters. The Germans spent this day in building up their line, and with their better railway facilities had probably the best of the bargain, although the British air service worked with their usual utter self-abnegation to make the operation difficult.
The new advance began upon the night November 22, when the 56th Londoners reinforced the Ulsters upon the left of the line on the out-skirts of the village of Mœuvres. To the west of the village, between it and the Hindenburg Line, was an important position, Tadpole Copse, which formed a flank for any further advance. This was carried by a surprise attack in splendid style by the 1st Westminsters of the 169th Brigade. During the day both the Londoners and the Ulstermen tried hard, though with limited success, to enlarge the gains in this part of the field.
The attack was now pointing more and more to the north, where the wooded height of Bourlon marked the objective. In the southern part the movements of the troops were rather holding demonstrations than serious attacks. The real front of battle was marked by the reverse side of the Hindenburg Line upon the left, the hill, wood, and village of Bourlon in the centre, and the flanking village of Fontaine upon the right. All of these were more or less interdependent, for if one did not take Bourlon it was impossible to hold Fontaine which lay beneath it, while on the other hand any attack upon Bourlon was difficult while the flanking fire of Fontaine was unquenched. From Mœuvres to Fontaine was a good six miles of most difficult ground, so that it was no easy task which a thin line of divisions was asked. to undertake—indeed only four divisions were really engaged, the Thirty-sixth and Fifty-sixth on the left, the Fortieth in the centre, and the Fifty-first on the right.
The operations of November 23 began by an attack by the enduring Fifty-first Division, who had now been four days in the fighting line against Fontaine Village—an attempt in which they were aided by a squadron of tanks. Defeated in the first effort, they none the less renewed their attack in the afternoon with twelve more tanks, and established themselves close to the village but had not sufficient momentum to break their way through it. There they hung on in most desperate and difficult fighting, screening their comrades in the main Bourlon attack, but at most grievous cost to themselves.
Meanwhile the Thirty-sixth Division had again attacked Mœuvres, and at one time had captured it all, save the north-west corner, but heavy pressure from the enemy prevented them retaining their grasp of it. The two brigades of this division upon the east of the canal were unable, unfortunately, to make progress, and this fact greatly isolated and exposed the Fortieth Division during and after its attack.
