On 7 January 1922 the Dáil voted to accept of the Treaty, with the Deputies having being called to vote by Diarmuid O’Hegarty one by one in order of their constituencies The Dáil decision to accept the Treaty split the movement. Shortly before de Valera resigned as President of the Dáil in January 1922, to be replaced by Arthur Griffith, GHQ had reassured him that the IRA would support the Government; but in reality it was as divided as Sinn Féin. Fortunately those IRA staff officers who declared against the Treaty did not head the operations and training branches of the IRA and this lack of expertise became apparent as the civil war progressed.
