On 11 Apr 1917 the 1st Battalion were in the lines at Fampoux and were ordered to attack Plouvain in support of Royal Irish Fusilers whilst the Household Battalion attacked towards Greenland Hill on their left. There were many casualties from shell-fire before starting and the attack was almost at once checked by the enemy's machine-guns. The 1st Battalion had advanced till they found the leading battalion held up. Then, since the fire from the Chemical Works and Railway Embankment (see below) made further progress impossible Major Sir G. Lacon (who was in command that day) ordered a line to be consolidated and at nightfall had established his battalion with the Royal Irish Fusiliers on the right and Household Battalion on the left.

The failure to achieve more was due partly to the fact that the brigade has been practically in the view of the enemy as it came up to the assembly and partly due to the heavy barrage which the Germans at once put down. The battalion remained in their advanced position till April 13th and were in support for a week longer. The losses from the 9th to 20th April were 50 killed, including Colin and 213 wounded or missing.
