A national executive was also elected, composed of 26 provincial representatives (including Dublin). In addition, a number of directors were elected to head the various IRA departments. Those elected were: Michael Collins (Director for Organisation); Diarmuid Lynch (Director for Communications); Michael Staines (Director for Supply); Rory O'Connor (Director of Engineering). Seán McGarry was voted General Secretary, while Cathal Brugha was made Chairman of the Resident Executive, which in effect made him Chief of Staff. There were six co-options to make-up the full number when the directors were named from within their ranks, including Diarmuid O'Hegarty.
