On December 14 the second and more sustained effort was made to get possession of the Petit Bois at Wytschaete, which had been attacked by the Lincolns upon the 9th. D'Urbal's Eighth French Army was co-operating upon the left. The British attack was conducted by Haldane's Third Division, and the actual advance was carried out, after a considerable artillery preparation from the batteries of two Corps, by Bowes' 8th Brigade, with the 2nd Royal Scots and the 1st Gordons in the lead. At 7.45 the guns were turned upon the big wood beyond Petit Bois, through which the supports might be advancing, and at the same hour the two regiments named swarmed forward, {325} the Lowlanders on the left and the Highlanders on the right. The Royal Scots, under Major Duncan, carried Petit Bois with a rush, taking fifty prisoners and two machine-guns, while the Germans fled out at the other end of the wood. The Scots at once entrenched themselves and got their own machine-guns into position. The Gordons, under Major Baird, advanced with splendid dash and gained some ground, but found the position such that they could not entrench upon it, so they were forced to fall back eventually to their original position. Both they and the 4th Middlesex, who supported them, lost considerably in the affair. The total casualties in the Petit Bois action came to over four hundred, with seventeen officers, figures which were considerably swollen by the losses of the Suffolks and Irish Rifles, who continued to hold the captured position in the face of continued bombing. The French in the north had no particular success and lost 600 men. The importance of such operations is not to be measured, however, by the amount of ground won, but by the necessity of beating up the enemies' quarters, keeping them pinned to their positions, and preventing them from feeling that they could at their own sweet wills detach any reinforcements they chose to thicken their line upon the Eastern frontier, where our Russian Allies were so insistently pressing.
