The advance of the Fifty-first Highland Territorial Division upon the immediate left of the Naval Division had been equally successful, and had ended in the capture of the important village of Beaumont Hamel with all its network of caverns, a great store of machine-guns, and 1500 of the garrison. The objectives of the division may be said to have been the continuation of those of the Naval Division, substituting Beaumont Hamel for Beaucourt, but the position {321} was complicated by a deep ravine, called after its shape the Y Ravine, which ran down from the village to the German trenches. The ground over which the advance was made was still littered with the skeletons clad in rags which represented the men who had fallen in the attack of July 1. Now, after five months, they were gloriously avenged. The rush of the division was headed by the 153rd Brigade, with the 4th and 7th Gordons in the lead. These two fine battalions carried the front German lines, but on reaching the Sunken Road they gave place to the 6th and 7th Black Watch behind them, who carried the attack up the Y Ravine and on to Beaumont, while the Seaforths and Argylls of the other brigades, with their staunch Lowland comrades of the 9th Royal Scots, thickened the line of attack, and gave it the weight to carry each successive obstacle. Only in the Y Ravine was there any momentary check to the fiery advance. There for a short time the Germans stood stoutly to their task, and there was some of that man-to-man work which the Scotsman loves. Then the last signs of resistance died out, and before the late afternoon the whole position was in the hands of the assailants, who pushed on and occupied the low ridge to the north which separates it from Serre. One curious incident connected with the close of the action was, that a mopping-up party of Gordons in one of the front lines of trenches were suddenly surprised and captured by a considerable body of Germans, who emerged suddenly from an underground tunnel. In the evening, however, the positions were reversed, and the prisoners were rescued, while the Germans had to surrender to the victors. Fifteen hundred prisoners and 54 machine-guns were the {322} spoils of the Fifty-first Division; but these were considerably increased when the dug-outs were more carefully examined next day. Altogether nearly 7000 officers and men were captured in the course of the action.
