On the morning of March 25 the line of the Third Army, which had defined itself more clearly during the night, ran from Curlu near the Somme, east of Bazentin, west of Longueval, east of Martinpuich, through Ligny Thilloy, Sapignies, Ervillers, and hence as before. The enemy, whose cavalry were well up and in force, at once began his thrusting tactics in the southern section of the field, and may have expected, after his advance of the day before, to find some signs of weakening resistance. In this he was disappointed, for both the 47th Londoners in front of Contalmaison and the Second Division at Ligny Thilloy beat off several attacks with {62} very great loss to the assailants. The units were much broken and mixed, but the spirit of the individuals was excellent. The pressure continued, however, to be very great, and in the afternoon the line was once more pushed to the westwards. There was severe fighting between Bapaume and Sapignies, where mixed and disorganised units still held the Germans back, but in the late afternoon three distinct gaps had appeared in the line, one between the Seventh and Fifth Corps, one in the Fifth Corps itself in the Pozières area of the Sixty-third Division, and one between the Fifth and the Fourth Corps. Fortunately, the resistance had been so desperate that by the time the Germans had their opportunity they were always so bedraggled themselves that they could not take full advantage of it. The general order of divisions in this area, counting from the south of Contalmaison, was Seventeenth, Forty-seventh, Sixty-third, Second, upon the morning of March 25. The Seventh Corps, the previous adventures of which will be described under the heading of the Fifth Army, had now become the right wing of the Third Army. It had been strengthened by the advent of the Thirty-fifth Division, and this unit now covered from west of Curlu to east of Maricourt, where it touched the right of the Ninth Division--if the thin ranks of that gallant band can be dignified by so imposing a title. The Highlanders covered the front to Montauban, where they touched the First Cavalry Division, but beyond that the enemy were pouring round their flank at Bernafoy and Mametz Woods. It was under these trying conditions that the Twelfth Division was ordered up, about noon, to secure the {63} left of the Seventh Corps and entirely stopped the dangerous gap.
