 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3–4 October 1918.This engagement was the battalion's last combat operation in the war, as the whole of 2nd Division was withdrawn from the line after the 6th Brigade's attack on Montbrehain on 5–6 October.On 10 October 1918, while resting near Vignacourt, the 19th Battalion was disbanded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.
