Irish War of Independence: Kilmichael Ambush: The Irish Republican Army ambush a convoy of British Auxiliaries and kill seventeen.

The Irish War of Independence, also known as the Anglo-Irish War, was a guerrilla war fought in Ireland from 1919 to 1921 between the Irish Republican Army and British forces: the British Army, along with the quasi-military Royal Irish Constabulary (RIC) and its paramilitary forces the Auxiliaries and Ulster Special Constabulary (USC). It was part of the Irish revolutionary period.

The Kilmichael ambush was an attack carried out on 28 November 1920 by the Irish Republican Army (IRA) near the village of Kilmichael, County Cork, during the Irish War of Independence. Thirty-six local IRA volunteers commanded by Tom Barry killed sixteen members of the Royal Irish Constabulary's Auxiliary Division. The Kilmichael ambush was politically as well as militarily significant. It occurred one week after Bloody Sunday and marked an escalation in the IRA's campaign.

The Irish Republican Army (IRA) is a name used by various resistance organizations in Ireland throughout the 20th and 21st centuries. Organisations by this name have been dominantly Catholic and dedicated to anti-imperialism through Irish republicanism, the belief that all of Ireland should be an independent republic free from British colonial rule.

The Auxiliary Division of the Royal Irish Constabulary (ADRIC), generally known as the Auxiliaries or Auxies, was a paramilitary unit of the Royal Irish Constabulary (RIC) during the Irish War of Independence. It was founded in July 1920 by Major-General Henry Hugh Tudor and made up of former British Army officers, most of whom came from Great Britain and had fought in the First World War. Almost 2,300 served in the unit during the conflict. Its role was to conduct counter-insurgency operations against the Irish Republican Army (IRA), acting mainly as a mobile striking and raiding force. It operated semi-independently of the RIC and was mainly deployed to southern and western regions where fighting was heaviest.
