On 9 May 1920, during the
Irish War of Independence, some 200
Irish Republican Army (IRA) volunteers under
Frank Aiken surrounded and attacked the
Royal Irish Constabulary (RIC) barracks in Newtownhamilton. After a two-hour firefight, the IRA breached the barracks wall with explosives and stormed the building. The RIC refused to surrender, even though the building was set alight with petrol from a potato-spraying machine. The 200-400 IRA men left the town at daybreak, discouraged and very drunk from the public house they had broken into beside the barracks, and had demolished the walk between the pub and the barracks. They left the RIC garrison still shouting 'No Surrender' and with the officers safe. One officer's wife and children had been hiding the whole time, with the mother helping to load the magazines for the constabulary. Newtownhamilton suffered significant disruption, damage and fatalities during
The Troubles from the late 1960s to the 1990s. The deadliest incident was the
Tullyvallen massacre. For more information, see
The Troubles in Newtownhamilton. While the
British Army had a major presence in the village during the conflict, this was scaled down and eventually removed entirely following the
Good Friday Agreement. In 2006 it was announced that the local police station would be upgraded to full-time status due to a recent bomb explosion caused by a still-active nationalist group. ==Demography==
