At 3 P.M. the enemy, about a battalion in strength, advanced in extended order from Hausa and Delbar Woods towards the railway east of the chemical works. This advance was again stopped by artillery fire, and many of the Germans turned and fled. Later, another force was seen forming up in rear of the Roeux-Plouvain Road, but was again dispersed by the artillery. At dusk the Germans made a further attempt to assemble for attack in the same place, but were similarly dispersed by the artillery. Seldom have gunners had such targets as were given them during these attacks. Time and time again the German infantry resolutely attempted to advance over the forward glacis of Greenland Hill in full view of the abundant observation posts on the battle front. Not until it was dark could he make his way through the barrage which the artillery and machine and Lewis gunners were able to fire, and regain the chemical works. During the day reports of enemy counter-attacks reached Divisional headquarters so constantly that a battalion of the 103rd Infantry Brigade was ordered forward as a reserve to the 154th Brigade; similarly a second battalion was placed at the disposal of the 153rd Brigade. After dark orders were issued for the 103rd Brigade, with the 26th and 27th Battalions Northumberland Fusiliers and the 6th Seaforth Highlanders, to take over the battle front of the 153rd Brigade. As soon as it had become clear that the enemy was again in possession of the chemical works, the 4th Seaforth Highlanders were ordered to make a further attempt to retake them. This attack was launched during the night, but failed to achieve its object. Dawn therefore broke to find the Black line south of the railway, some of the buildings just north of the station and a trench line east of the Gavrelle-Roeux Road north of the station, in our hands. This line was maintained throughout the night, in spite of many attempts made by the enemy to penetrate it. On 24th April no important actions occurred, both sides being too exhausted to continue the engagement. The enemy's artillery, however, remained very active on the Black line. On the night 24-25th April the Division was relieved by the 34th Division, with the exception of the 6th Seaforth Highlanders. It was arranged by the Brigadier commanding the 103rd Brigade that the 26th Northumberland Fusiliers, who were holding the line on the 154th Brigade front, should be relieved on that front, and move across to relieve the 6th Seaforth Highlanders. Dawn had, however, broken before the relief of the 6th Seaforth Highlanders had been begun. In consequence, the battalion had to spend another very uncomfortable twenty-four hours in the line. On the 25th Divisional headquarters moved back to Chelers, the 152nd Brigade to Acq, the 153rd and 154th Brigades to the Tincques-Ligny-St Flochel area. The following day the 152nd Brigade moved to the Ternas area.
