After the departure of Redmond and his followers, the Volunteers adopted a constitution, which had been drawn up by the earlier provisional committee, and was ratified by a convention of 160 delegates on 25 October 1914. It called for general council of fifty members to meet monthly, as well as an executive of the president and eight elected members. In December a headquarters staff was appointed, consisting of Eoin MacNeill as chief of staff, The O'Rahilly as director of arms, Thomas MacDonagh as director of training, Patrick Pearse as director of military organisation, Bulmer Hobson as quartermaster, and Joseph Plunkett as director of military operations. The following year they were joined by Éamonn Ceannt as director of communications and J.J. O'Connell as chief of inspection.
