Irish War of Independence

The Irish War of Independence was a guerrilla warfare style campaign which lasted from January 1919 until July 1921. Its beginning is normally traced to the ambush led by Dan Breen of two RIC men escorting a consignment of gelignite to a quarry in Soloheadbeg, Co. Tipperary. Although an independent action, the ambush was supported by the First Dáil, which had first convedned on that same day - 21st January, 1919. Events then soon escalated. It took a few months for the central authority to gain control of the various rebel groups throughout the country, and establishing central authority was not helped early in the war by the well known fued between Cathal Brugha, Minister for Defence and Michael Collins, Minister for Intelligence.

The Irish Republican Army (Also known more widely at the time as the Irish Republican Brotherhood) attacked sporadically the forces of the British government with the intention of breaking Britain's will to rule Ireland. This campaign paralleled the political efforts of Sinn Féin to create an independent Irish Republic by means of the illegally decreed, though democratic, assembly of Dáil Éireann which in practise would 'defeat England by ignoring it'. The War is generally seen as the beginning of modern guerrilla warfare, with the reliance of the IRA on non-uniform "flying columns", comprised of local men, playing a large part in its success.

The war was prosecuted ruthlessly by the IRA. The British retaliated in kind, introducing two new irregular forces into Ireland, the Black and Tans and the Auxiliaries. In general, the fighting was conducted on a low-level, vicious basis with regular small bombing and shooting attacks similar to the Irish Troubles. Fewer than 2,000 IRA volunteers at any given time were faced by over 50,000 crown forces. It was not a nationwide contest: the IRA depended upon energetic local leaders. Where there were none, there was little fighting. Irish attacks were regularly followed by British counter attacks which generally were aimed at residential areas. Due to the fact that the guerilla's merged into the local countryside or city, they were notoriously hard to root out and the British forces went to extraordinary - and in some cases downright repressive - measures to find and kill suspected IRA members. Many innocents were severely injured or killed in the course of this, and public dis-satisfaction with the British continued to grow. The Use of the Black and Tans also led to great resentment, as these were British men who had returned from the Trench warfare of World War I and found it difficult to return to civilian life. They often employed very oppressive measures and inspired generations of Irish literature and music dedicated to describing the Black and Tans as rough and cruel thugs. Some historians have argued that the Black and Tans were largely the reason behind the failure of the British to truly kill off the Rebellion, as their actions often persuaded young people to take up arms in the name of independance.

In total, 15,000 volunteers fought in the war, with generally 2-3,000 active at any time. Their greatest strength lay in the provinces of Connaught and Munster, and the principal areas of conflict were in counties Dublin, Cork, Limerick, Tipperary, Clare, Kerry and Longford. The volunteers were generally aged between 20 and 30, from middle and working class backgrounds, and were overwhelmingly Catholic. As the conflict progressed, the membership became younger, more urban-based and more working class. The force fought a limited and successful guerrilla war, pitting broad public support and knowledge of the terrain and people against the British army's superior weaponry and numbers, until stalemate was acknowledged by a truce called in July 1921, which began the negotiations leading to the signing of the Anglo-Irish Treaty in December of that month.

The IRA, following the division in the Dáil, split over the terms of the Treaty. A minority supported and joined the Free State Army, quickly built up by Collins with British government support (the ‘regulars’); the majority of the IRA - perhaps 80 per cent, encompassing the most experienced men from the south, west and Dublin - organised and fought against the new state (the ‘irregulars’) in the Irish Civil War, 1922-23.
