It was now the turn of the 107th Brigade. The sappers passed a busy and disturbed night. The shelling of the Lys continued, and there was a direct hit on the bridge, a pontoon being damaged and a length of the superstructure destroyed. By desperately hard work all repairs were completed for the leading battalion of the 107th Brigade, the 15th Rifles, to cross at 2 a.m. This battalion, followed by the 1st, moved forward, the former forming up west of the Courtrai-Ghent Road, in relief of the 9th Inniskillings, which withdrew through its ranks. Troops of the 9th Division had crossed about midnight, but, as may easily be imagined, it was not without considerable difficulty that touch was obtained with them. This, however, was at last accomplished, but the line at the point of junction was perilously close to the river, owing to the fact that German machine-gunners still held out in Beveren.

At 6 a.m. on the 20th the new attack began. Beveren was quickly taken, with some aid from the Scots Fusiliers of the 9th Division. Machine-gun fire was very heavy, and the 15th Rifles had considerable casualties. The commanding officer, Lieut.-Colonel B. Y. Jones, D.S.O., was killed. But the advance continued at a great pace. The main Courtrai-Ghent-Antwerp Railway was crossed before eight o'clock. An hour later the line was astride the road from Deerlyck—already in the hands of the 9th Division—to Waereghem. A mill on that road gave considerable trouble, but was eventually taken by a platoon of the 1st Rifles. Further progress for the time being was found impossible. The advance had reached a point two and a half miles from the Lys, and could no longer be supported by artillery fire. At 12-30 p.m. the 1st Inniskillings made another attempt to clear Dries, and reached the centre of the hamlet. Resistance was now quite determined, and it was decided to await the crossing of the French before attempting any move on the left flank. About two hundred prisoners had been captured in the day's operations.

The Engineers had continued their good work. By evening a pontoon bridge for first-line transport had been thrown across by the 150th Field Company. The 121st had completed a good permanent foot-bridge, and, returning to the abandoned trestle, for which all materials had been collected locally, had finished that also. At night the 108th Brigade and a French regiment on the left made the crossing. Artillery, however, could not cross yet awhile. The 108th Brigade was to relieve the 109th, and the advance was to be continued for another twenty-four hours without it.

The advance of the 21st was timed for 7-30 a.m. It was to be carried out by the 1st Rifles of the 107th Brigade, and the 1st Irish Fusiliers of the 108th. It was, however, important to be rid of the hornet's nest in Dries upon the flank, and this village was cleared by a company of the 12th Rifles before the attack began. Without artillery this attack was of the greatest difficulty. There were no hedges, and it was the custom in this part of the country to lop the lower branches off the trees. Consequently, the attacking force was constantly exposed to long-range machine-gun fire. Moreover, the 133rd French Regiment, since it had to fight its way from the river bank, was always in rear. In all the circumstances the advance of the day, which found the right of the 107th Brigade at Knock, north of Vichte, and the left of the 108th at Spitael, on the Ghent Railway, was highly creditable to the troops concerned. The advance of the 107th Brigade, with the 9th Division on its right, was to be resumed on the morrow, but it was decided that the 108th Brigade should not move till the French had come up into line.

By the morning of the 22nd the Lys was crossed by bridge after bridge in the area of the 36th Division; there being, besides numerous foot-bridges, three medium bridges for first-line transport, and a trestle which was subsequently used by French motor-lorries. On the night of the 21st the four batteries of the 153rd Brigade R.F.A. crossed the river, to fire a barrage in support of the 107th Brigade next day. On the right, upwards of half the distance between the parallel rivers, the Lys and the Escaut, had now been covered. From the Gaverbeek onwards the advance was now faced by rising ground, which culminated in a general ridge before the drop down, over some two miles, to the valley of the latter river. The various little crests of this chain afforded excellent positions to the enemy, and it was evident that, if so disposed, he could make a very effective stand before falling back across the Escaut. The first of them had to be attacked on this morning. It was taken by the 2nd Rifles. The barrage, small though it would have been reckoned in old days, and as it was in comparison with the German barrage which had to be faced, nevertheless made a wonderful difference to the attack. The little rise, about a mile north-east of Vichte and topped by a windmill, was carried. But there followed the most resolute counter-attack experienced for a long time by the 36th Division. It was made by a Prussian Assault Battalion, and succeeded in driving our men off the crest and back for almost eight hundred yards. Colonel Becher, commanding the 2nd Rifles, organized a new attack by two companies, which, going forward with the greatest gallantry, once more drove the Germans off the crest and re-established the position. The left flank swung sharply back, the junction with the 108th Brigade being on the Deerlyck-Waereghem Road. On the left of the 108th Brigade the French, after heavy fighting, were established in Spitael.

On the 23rd, as the enemy appeared to be withdrawing, the advance was continued all along the line behind a screen of scouts. A squadron of French dragoons, attached to the Division, made a spirited dash for the Escaut crossing at Berchen, but came under heavy machine-gun fire from the second line of hills, which it was evident the enemy held in force. He had, in fact, withdrawn a mile or so during the previous night. On the extreme left a company of the 1st Irish Fusiliers, entering Heirweg, was vigorously counter-attacked and driven out with the loss of several prisoners. Eventually a liaison post was established by British and French at the station, just west of the hamlet. On the right the 1st Rifles had captured Vossenhoek and Hutteghem. The advance had been well maintained. The men of the 107th Brigade were now, however, weary, and the battalions very weak. It was decided to relieve the Brigade that night by the 109th. This was carried out without event.

The following day was given to reorganization. Two batteries of the 173rd Brigade had crossed the river on the 22nd, the remainder were now brought over in readiness to support an attack upon the ridge. This took place at 9 a.m. on the 25th. The 109th Brigade on the right had two battalions, the 1st and 2nd Inniskillings, in line; the 108th one only, the 12th Rifles. The advance was covered by a barrage moving at the rate of a hundred yards in three minutes. On the right not much progress was made, in face of heavy machine-gun fire. Loss of direction, due to fog and the smoke-screen of the enemy barrage, caused considerable difficulty. Eventually a line east of Hutsbosch was consolidated. On the left the 12th Rifles made an advance of half a mile, in face of the most determined opposition encountered since the fighting at Hill 41. Every house was held, and the Germans fought their machine-guns desperately. No less than ten were counted in ten separate houses at the day's end. The advance would have been greater had the French supported it on the left, but their line had not moved beyond Heirweg. The work of the 12th Rifles on this day was probably the best performed by that battalion, amid much good work accomplished since the beginning of offensive operations. Repeatedly the men had charged in upon houses defended by machine-guns, and bayoneted the detachments.

The 9th Division had captured the twin crests of Ingoyghem and Ooteghem, and it was determined that the 109th Brigade should, the same afternoon, assault that of Kleineberg, to their north-east, which would have brought the right of the Division, its left drawn back through circumstances beyond its control, into the van of the advance. A new barrage, starting at 5 p.m., was hastily planned and admirably carried out. Unfortunately, however, orders did not reach the battalions soon enough, and, at the appointed hour, three companies only, two of the 1st Inniskillings and one of the 2nd, went forward to the attack. And it must be remembered that companies were now never more than fifty strong. The crest was actually reached, but the advance had been on a frontage so narrow that it was impossible to maintain the position. A farm-house at the foot of the slope was, however, held and consolidated.
