20th Brigade was in support on the first day of the Battle of Neuve Chapelle (10 March 1915), moving up to the front that night and only suffering a few casualties from stray shrapnel. On the second day it was tasked with moving out from the 'Moated Grange' position into the gap between the leading brigades of 7th and 8th Divisions and then advance to take Aubers village. Although the orders arrived late, the brigade moved off on time at 07.00 in column of platoons, but came under heavy shellfire and flanking machine gun fire and suffered severely. Most of the two leading battalions (1st Grenadiers and 2nd Gordons) had to take what cover they could before even reaching the position of the leading brigades, having suffered about 500 casualties. A new attack was ordered for the afternoon but failed. The following morning (12 March) the Scots Guards and Border Regiment were instructed to pass through the leading brigades. Although the attack was postponed, the runners carrying the recall orders were killed and the leading companies of both battalions advanced into No Man's Land until they were pinned down by machine gun fire from a German position known as the Quadrilateral. When the delayed British bombardment came down, it was accurate and effective, completely demoralising the German defenders. The Scots Guards and Border Regiment crept forward under cover of the bombardment and rushed the Quadrilateral, taking 400 prisoners. However, the brigade was unable to push any further through the maze of trenches.
