The British front was cut across diagonally by a considerable canal with deep sides, the Canal du Nord. Upon the north side of this was one division. This flank unit was the famous Thirty-sixth Ulsters, who behaved this day with their usual magnificent gallantry. Advancing with deliberate determination, they carried all before them, though exposed to that extra strain to which a flank unit must always submit. Their left was always enfiladed by the enemy and they had continually to build up a defensive line, which naturally subtracted from their numbers and made a long advance impossible. None the less, after rushing a high bank bristling with machine-guns they secured the second Hindenburg Line, where they were firmly established by 10.30 after a sharp contest with the garrison. They then swept forward, keeping the canal upon their right, until by evening they had established themselves upon the Bapaume-Cambrai Road. It was the brigade moving parallel to the Sixty-second Division upon which the heavier work fell. Upon the immediate right of the Irishmen was Braithwaite's Sixty-second Division of West Riding Yorkshire Territorials--one of those second line units whose solid excellence has been one of the surprises of the war. Six of them had already come to the front, and not one of the six which had not made its {244} mark. On this occasion the men of the West Riding made an advance which was the admiration of the army, and which the Field-Marshal, who weighs his words carefully, described as "a brilliant achievement." The first obstacle in front of the 185th West Yorkshire Brigade upon the right was the village of Havrincourt, which, with the aid of the tanks, they carried in dashing style, though the resistance from the Château was very fierce. Behind it lay the reserve German line, which also was taken at the point of the bayonet. Upon the left the 187th Brigade, containing two Yorks and Lancaster and two Yorkshire Light Infantry battalions, swept gloriously forward and got every objective, including the northern half of Havrincourt. The 2/5th Yorkshire Light Infantry was particularly fine, as it charged without tanks and yet kept up with the line. The 186th Brigade, consisting of four battalions of the West Riding Regiment, then passed through in a splendid rush which carried them up to and through the village of Graincourt, regardless of the fact that Flesquières on the right was untaken. Surging on the 188th Reserve Brigade reached and captured the important village of Graincourt, much aided by two audacious tanks. With an energy which was still unabated they pushed on to Anneux, where they reached the fringe of the houses. It was a truly splendid day's work, in which four and a half miles of every devilry which German sappers could build or German infantry defend was inexorably beaten down. In all these operations they were aided and supported, not only by the tanks, but by the 11th Hussars, and
