"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.
"On the 13th, the various reliefs having been completed without incident, the heaviest bombardment yet experienced broke out at 4.30 A.M., and continued with little intermission throughout the day. At about 7.45 A.M. the Cavalry Brigade astride the railway, having suffered very severely, and their trenches having been obliterated, fell back about 800 yards. The North Somerset Yeomanry, on the right of the Brigade, although also suffering severely, hung on to their trenches throughout the day, and actually advanced and attacked the enemy with the bayonet. The Brigade on its right also maintained its position; as did also the Cavalry Division, except the left squadron, which, when reduced to sixteen men, fell back. The 2d Essex Regiment, realizing the situation, promptly charged and retook the trench, holding it till relieved by the cavalry. Meanwhile a counter-attack by two cavalry brigades was launched at 2.30 P.M., and succeeded, in spite of very heavy shrapnel and rifle fire, in regaining the original line of trenches, turning out the Germans who had entered it, and in some cases pursuing them for some distance. But a very heavy shell fire was again opened on them, and they were again compelled to retire to an irregular line in rear, principally the craters of shell holes. The enemy in their counter-attack suffered very severe losses.
"The fighting in other parts of the line was little less severe. The 1st East Lancashire Regiment were shelled out of their trenches, but their support company and the 2d Essex Regiment, again acting on their own initiative, won them back. The enemy penetrated into the farm at the northeast corner of the line, but the 1st Rifle Brigade, after a severe struggle, expelled them. The 1st Hampshire Regiment also repelled an attack, and killed every German who got within fifty yards of their trenches. The 5th London Regiment, despite very heavy casualties, maintained their position unfalteringly. At the southern end of the line the left brigade was once again heavily shelled, as indeed was the whole front. At the end of a very hard day's fighting, our line remained in its former position, with the exception of the short distance lost by one cavalry division. Later, the line was pushed forward, and a new line was dug in a less exposed position, slightly in rear of that originally held. The night passed quietly.
"Working parties of from 1,200 to 1,800 men have been found every night by a Territorial Division and other units for work on rear lines of defence, in addition to the work performed by the garrisons in reconstructing the front line trenches which were daily destroyed by shell fire.
"The work performed by the Royal Flying Corps has been invaluable. Apart from the hostile aeroplanes actually destroyed, our airmen have prevented a great deal of aerial reconnaissance by the enemy, and have registered a large number of targets with our artillery.
"There have been many cases of individual gallantry. As instances, may be given the following:
