"After a comparatively quiet night and morning (10th-11th) the hostile artillery fire was concentrated on the trenches of the 2d Cameron Highlanders and 1st Argyll and Sutherland Highlanders at a slightly more northern point than on the previous day. The Germans attacked in force and gained a footing in part of the trenches, but were promptly ejected by a supporting company of the 9th Royal Scots. After a second short artillery bombardment the Germans again attacked about 5.15 P.M., but were again repulsed by rifle and machine-gun fire. A third bombardment followed, and this time the Germans succeeded in gaining a trench--or rather what was left of it--a local counter-attack failing. However, during the night the enemy were again driven out. The trench by this time being practically non-existent, the garrison found it untenable under the very heavy shell fire the enemy brought to bear upon it, and the trench was evacuated. Twice more did the German snipers creep back into it, and twice more they were ejected. Finally, a retrenchment was made, cutting off the salient which had been contested throughout the day. It was won owing solely to the superior weight and number of the enemy's guns, but both our infantry and our artillery took a very heavy toll of the enemy, and the ground lost has proved of little use to the enemy. "On the remainder of the front the day passed comparatively quietly, though most parts of the line underwent intermittent shelling by guns of various calibers. "With the assistance of the Royal Flying Corps the 31st Heavy Battery scored a direct hit on a German gun, and the North Midland Heavy Battery got on to some German howitzers with great success. "With the exception of another very heavy burst of shell fire against the right Division early in the morning the 12th passed uneventfully. "On the night of the 12th-13th the line was reorganized, the center Division retiring into Army Reserve to rest, and their places being taken in the trenches by the two Cavalry Divisions; the Artillery and Engineers of the center Division forming with them what was known as the 'Cavalry Force,' under the command of General De Lisle.
