"Come Out, Ye Black and Tans" (sometimes "Black and Tan") is an Irish rebel song referring to the Black and Tans, the British paramilitary police auxiliary force in Ireland during the 1920s.
 The song was written by Dominic Behan as a tribute to his father Stephen although authorship of the song is often attributed to Stephen.
 The melody was adapted from an old air, Rosc Catha na Mumhan (Irish for Battlecry of Munster) by Piaras Mac Gearailt (Pierce FitzGerald c.1709-c.1792), which is also used for the loyalist song, The Boyne Water, as well as several other songs in English and Irish.
The ambush was carried out by the IRA's South Leitrim Brigade on a force of Black and Tans.
 The British suffered casualties and admitted one fatality, a captain in the Bedfordshire Regiment, although some local sources claimed several more were killed.
 The Black and Tans later ran amok in Carrick-on-Shannon, burning the Temperance Hall in Gowel.
John Henry Barlow (1855 – 1924) was widely referred to as ‘The outstanding Quaker statesman of his generation'.
 He was also an outstanding ambassador for peace during the war years and as clerk of London Yearly Meeting for seven crucial years was the person, who more than anyone held the Society together at a taxing moment in its history.
 He was one of the first members of the Friends' Ambulance Unit.
 He was the first Secretary and general manager of the Bournville Village Trust, serving the trust for 23 years.
 In 1920 he led a delegation to Ireland to look into the Black and Tans atrocities.
An expatriate Irish population in any country other than Ireland or Northern Ireland is generally considered to be Irish emigrants and their descendants, at least to the extent that the people involved are aware of their Irish heritage and willing to acknowledge it.
 This definition applies to over 80 million people, considerably more than the 3 million of Irish nationality who reside in other countries.
 This smaller group is defined by the government of Ireland in legal terms as those of Irish nationality who habitually reside outside of the island of Ireland.
 It includes Irish citizens who have emigrated abroad and their children, who are Irish citizens by descent under Irish law.
 It also includes their grandchildren in cases where they were registered as Irish citizens in the Foreign Births Register held in every Irish diplomatic mission.
The Black and Tans (Irish: "Dúchrónaigh" ), officially the Royal Irish Constabulary Special Reserve, was a force of Temporary Constables recruited to assist the Royal Irish Constabulary (RIC) during the Irish War of Independence.
 The force was the brainchild of Winston Churchill, then British Secretary of State for War.
 Recruitment began in Great Britain in late 1919.
 Thousands, many of them British Army veterans of World War I, answered the British government's call for recruits.
 Most of the recruits came from Britain, although it also had some members from Ireland.
 Their role was to help the RIC maintain control and fight the Irish Republican Army (IRA), the army of the Irish Republic.
 The nickname "Black and Tans" arose from the colours of the improvised uniforms they initially wore, composed of mixed khaki British Army and rifle green RIC uniform parts.
 The Black and Tans became infamous for their attacks on civilians and civilian property.
Guerrilla Days in Ireland is a book published by Irish Republican Army leader Tom Barry in 1949.
 The book describes the actions of Barry's Third West Cork Brigade during the Anglo-Irish War, such as the ambushes at Kilmichael and Crossbarry, as well as numerous other less known attacks made by the Brigade against the British Army, Black and Tans, the Auxiliary Division and Royal Irish Constabulary.
