The loss, however, was limited--as a loss--to the treacherous massacre of several hundred gallant men, and the capture of two of the supporting guns. The Gunners, as usual, behaved with the utmost gallantry, but they too came under the same enfilading fire as the Dorsets and every man of the detachment except Captain Boscawen fell either killed or wounded. Two of the guns were captured, but, with this, the material advantage gained by the enemy began and ended, for the 1st Cheshires were brought up from reserve and, with their co-operation, the morning's line was re-occupied. The Cheshires, however, themselves suffered considerably, among their casualties being their C.O., Col. Vandeleur, who was killed while leading the attack.[3] [3] Col. Vandeleur, while leading the Cheshires at Givenchy, was _not_ killed as originally reported, but was wounded, fell into the hands of the Germans and finally escaped to England. On the 15th, as though in fury at the loss of their gallant General, the 3rd Division, now under the command of General Mackenzie, fought with a dash and determination which were irresistible. Their advance was continually checked by the country dykes, but, in spite of these hampering obstacles, the Germans were everywhere driven back with heavy loss. The 4th Middlesex and the 2nd R. Scots again did particularly good work, and, further north, in the 9th Brigade, the R. Fusiliers and the Northumberland Fusiliers gained high praise from the A.C. Commander for the vigour and activity with which they pushed forward in the face of strong opposition. Conneau's cavalry, filling the eight-mile gap between the two Army Corps, also made good progress, as did the 3rd A.C., on the left. In the case of the latter Army Corps the 6th Division succeeded in reaching Sailly without encountering serious opposition, while the 4th Division got as far as Nieppe. The 2nd A.C., in its attempt to wheel, had so far advanced its left flank three miles in the last four days at a cost of 90 officers and 2,000 men. It had, however, inflicted very heavy losses on the enemy. On the 16th the 3rd Division continued the wheeling movement with little opposition till it reached the village of Aubers, which was found to be strongly held, and where it was brought up short.
