The one Lancashire Special Reserve battalion that saw active service was the 4th Bn King's (Liverpool Regiment) – possibly because one of that regiment's regular battalions spent the war in India and did not require so many reinforcements. It went to the Western Front in March 1915, joining the 3rd (Lahore) Division in the Indian Corps and serving with it at the Second Battle of Ypres. Early in 1916 the battalion joined 33rd Division, fighting with it on the Somme, at Arras, and in the Battle of Polygon Wood. It fought against the German spring offensive in 1918, and participated in the Allies' final Hundred Days Offensive to the end of the war.
