On February 1 the Battalion moved from Courcelette to Ovillers Huts, and on the 5th went on to Senlis, moving to Wolfe Huts on the 15th, and into the line for operations a day later.

Intense cold was experienced at this time. The ground, like iron, was covered with snow. The frost was intense, one man being actually frozen stiff at his post on sentry, and drinking water carried to the front line arrived as lumps of ice, from which bits were chipped for eating.

An attack on the German trenches was made on February 17. Unluckily a day before the attack the frost gave way, a very rapid thaw set in, making No Man's Land deep and heavy with slush and mud. Moving to the attack over such ground was terrible; the objective line was reached, but the following casualties were sustained:

Officers killed8
Officers wounded4
Officers missing1
13
Other ranks killed30
Other ranks wounded165
Other ranks missing32
227

The Battalion held the Red Line on February 18, and in the night was relieved and moved to Ovillers Huts again. On the 24th it moved to Bruce Huts, and on the 26th to Albert, returning to Ovillers Huts on the 27th.

March 5 found the Battalion back in the trenches at Courcellette, and on the 10th "D" Company cooperated with the 1st Royal Berks and the 1st King's Royal Rifle Corps in an attack on Grevillers Trench and Lady's Leg Ravine, taking the ravine, killing about 20 of the enemy, and capturing 30 men and 2 machine guns. The casualties of the company amounted to 7 other ranks killed, 26 wounded, 1 accidentally wounded, and 2 died later from their wounds.

The following day the Battalion moved to Wolfe Huts, and on the 19th to Albert again, proceeding from there to Contay, Amplier, Bonnières, Framecourt, Aumerval, and Bailleul les Pernes.

Vimy Ridge.—From Bailleul les Pernes the Battalion moved up to Larosette, behind Vimy Ridge, ready to go in and take over a part of the Ridge after its capture in the coming battle for its possession. On the night of April 11, in a blinding snowstorm, the Battalion relieved the 1/5th Gordons on the captured Ridge, and on the 13th continued the advance to the line of the railway, captured the village of Bailleul, established a line on the enemy side of it, and sent out patrols to Oppy, which was found to be very strongly held by the enemy.
