In 1917, the 19th Battalion was involved in the attack on German forces after their retreat to the Hindenburg Line. The battalion also took part in three other major battles in 1917, Second Bullecourt, Menin Road and Poelcappelle in Belgium. In 1918 the battalion helped to repel the German spring offensive, and it was during this time, on 7 April 1918, that Lieutenant Percy Storkey earned a Victoria Cross for his actions during the fighting in Hangard Wood. Following this, the battalion took part in the Allied offensive that eventually brought about the end of the war, fighting around Amiens and Mont St Quentin before coming up against the "Beaurevoir Line" at Estrees on 3–4 October 1918. This engagement was the battalion's last combat operation in the war, as the whole of 2nd Division was withdrawn from the line after the 6th Brigade's attack on Montbrehain on 5–6 October. On 10 October 1918, while resting near Vignacourt, the 19th Battalion was disbanded in order to reinforce other battalions in the 5th Brigade.
