The outbreak of World War I in August 1914 provoked a serious split in the organisation. Redmond, in the interest of ensuring the enactment of the Home Rule Act 1914 then on the statute books, encouraged the Volunteers to support the British and Allied war commitment and join Irish regiments of the British New Army divisions, an action which angered the founding members. Given the wide expectation that the war was going to be a short one, the majority however supported the war effort and the call to restore the "freedom of small nations" on the European continent. They left to form the National Volunteers, some of whose members fought in the 10th and 16th (Irish) Division, side-by-side with their Ulster Volunteer counterparts from the 36th (Ulster) Division.
