These attachments had all been to formations of the Regular Army, but on 25 November 1915, 2nd Division exchanged 19th Bde with a brigade from 33rd Division, a newly-arrived 'New Army' ('Kitchener's Army') formation. The intention was to share experience, and as soon as it joined 33rd Division, the brigade exchanged one of its veteran battalions with one of the newcomers. It remained with 33rd Division on the Western Front until the Armistice with Germany. Like the rest of the BEF, it was reduced from a four-battalion to a three-battalion establishment in February 1918.
