Irish War of Independence: One of the biggest engagements of the war takes place at Crossbarry, County Cork. About 100 Irish Republican Army (IRA) volunteers escape an attempt by over 1,300 British forces to encircle them.

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 Crossbarry ambush, also known as the Battle of Crossbarry, occurred on 19 March 1921 and was one of the largest engagements of the Irish War of Independence. It took place near the small village of Crossbarry in County Cork, about 20 km south-west of Cork city. About a hundred Irish Republican Army (IRA) volunteers, commanded by Tom Barry, escaped an attempt by about 1,200 British troops to encircle them. During the hour-long battle, ten British troops and three IRA volunteers were killed.
