The battalion's first major engagement happened on 16 June 1915, at Hooge, east of Ypres. The 9th Brigade, with the 7th Brigade in support, was chosen to conduct a three-phased attack with the ultimate intention being to reach trenches on the south-western edge of Bellewaarde Lake. Situated behind German lines was Bellewaarde Ridge, a tactically-important feature that overlooked British positions. At 0415, the first wave of troops moved on their objective and quickly secured the first-line trenches, which continued to be shelled by British artillery. The Liverpool Scottish and 1st Lincolnshire Regiment, forming the second wave, then left their trenches to pass through the first wave of attackers and reach the German second-line. Although the advance was relatively unopposed, "V" Company encountered resistance on its front from machine-gun fire. After briefly suspending its advance, the company, reinforced by "Z", charged the opposing positions and took about 40 prisoners.
