Crossmaglen

]] On 13 January 1921, during the Irish War of Independence, the Irish Republican Army (IRA) shot dead an Ulster Special Constabulary (USC) constable in Crossmaglen. He was the first member of the USC to be killed whilst on duty. Crossmaglen, along with the rest of South Armagh, would have been transferred to the Irish Free State had the recommendations of the Irish Boundary Commission been enacted in 1925.

The British Army had a major presence in the area during the Troubles. Crossmaglen and the wider South Armagh/South Down area was a republican stronghold and republican paramilitaries were very active, earning the area the nickname "Bandit Country." Labour Party MP Clare Short said in 1983 "It is ridiculous that British troops are here in Crossmaglen. The claim is that they're in Ireland keeping the peace between the two communities. But there is only one community in South Armagh, so what the heck are they doing here?" During the Troubles, at least 58 police officers and 124 soldiers were killed by the Provisional Irish Republican Army in South Armagh, many in Crossmaglen itself.
