The 3rd (Reserve) and 4th (Extra Reserve) Battalions spent the whole war in England, the 3rd Bn in the Humber Garrison and the 4th initially at Barrow-in-Furness and later in the Severn Garrison. They fulfilled their dual role of coast defence and preparing reinforcement drafts of regular reservists, special reservists, recruits and returning wounded for the regular battalions serving overseas. Thousands of men would have passed through their ranks during the war. While at Hull the 3rd Bn probably assisted in the formation of 13th (Reserve) Battalion, Lancashire Fusiliers, from Kitchener's Army volunteers.
