"A" and "B" Batteries, 255th Brigade, crossed the canal by the bridge due south of Riez-du-Vinage, closely followed by the enemy. Majors Davidson and Jack, the two battery commanders, however, each dropped the last of their guns within 300 yards of the bridge to cover the withdrawal of their remaining guns. Of these one gun covered a foot-bridge and the other a drawbridge. The Germans were so close on the heels of the artillery that they were able to rush the drawbridge and establish themselves in a house on the west side of it. Major Jack, however, brought such effective shell-fire on to this house that the enemy fled from it and recrossed the canal, whereupon Major Fairlie, Lieutenant Mackay, and Driver Boyd took up rifles, occupied the bridgehead, and by their fire forced the enemy to retire down the road. In the meantime Major Davidson with his gun was firing on enemy machine-guns which had been brought up close to the Canal, and by the accuracy of his fire effectually covered the withdrawal of two heavy batteries which were coming up out of action under heavy fire. A description of this action, in which Major Davidson and Major Jack were mentioned by name, was included in the Commander-in-Chief's despatches dealing with the battle, Major Davidson being subsequently awarded a bar to the D.S.O. and Major Jack the D.S.O. It would be difficult to overestimate the valuable part played by these two guns and the gallant conduct of all concerned in restoring a situation at so critical a stage. Undoubtedly had it not been for the prompt action of Davidson and Jack, the enemy would have succeeded in establishing himself on the southern bank of the La Bassée Canal. The enemy, opening fanwise from his area of penetration, had been rapidly pressing his attack north, west, and southwards. Numerous attempts were made to improvise lines of defence, but in the absence of officers these all broke down until the infantry had withdrawn across the Clarence river, where they linked up with the 5th D.C.L.I. in front of Calonne. The line was then continued northwards along the Turbeaute and Ancienne Lys rivers. Southwards, as has already been described, the enemy reached the northern bank of the La Bassée Canal. The 154th Brigade farther eastwards had, however, formed a defensive flank, which prevented the enemy from extending his gains in this quarter. The 4th Seaforth reinforcements throughout these operations had held their ground about La Tombe Willot, the remnants of the 152nd Brigade were disposed facing north about La Vertbois Farm, extending from La Tombe Willot almost to Pacaut Wood. Here they joined part of the 8th Royal Scots and 404th Field Company in Pacaut Wood facing north. Meanwhile patrols of the 1st Gordon Highlanders, 3rd Division, were entering Pacaut Wood from the south.
