Shortly after the formation of the Volunteers, the British Parliament banned the importation of weapons into Ireland. The "Curragh incident" (also referred to as the "Curragh Mutiny") of March 1914, indicated that the government could not rely on its army to ensure a smooth transition to Home Rule. Then in April 1914 the Ulster Volunteers successfully imported 24,000 rifles in the Larne Gun Running event. The Irish Volunteers realised that it too would have to follow suit if they were to be taken as a serious force. Indeed, many contemporary observers commented on the irony of "loyal" Ulstermen arming themselves and threatening to defy the British government by force. Patrick Pearse famously replied that "the Orangeman with a gun is not as laughable as the nationalist without one." Thus O'Rahilly, Sir Roger Casement and Bulmer Hobson worked together to co-ordinate a daylight gun-running expedition to Howth, just north of Dublin.
