O'Hanlon was born in Ballybay, County Monaghan, Ireland, into a staunchly republican family, Feargal O'Hanlon was a draughtsman employed by Monaghan County Council.
He was a Gaelic football player and a keen Irish language activist. Aged 20, O'Hanlon was killed along with Seán South while taking part in an attack on the Royal Ulster Constabulary (RUC) barracks in Brookeborough, County Fermanagh, during the Border Campaign. Several other IRA members were wounded in the botched attack.
The IRA fled the scene in a dump truck. They abandoned it near the border. They left South and O'Hanlon, both then unconscious, in a cow byre, and crossed into the Republic of Ireland on foot for help for their comrades.
The wounded IRA men were treated as "car crash victims" by sympathetic staff in the Mater Misericordiae Hospital in Dublin. The events and personalities are sympathetically recalled in Dominic Behan's ballad The Patriot Game. A marble monument now stands at the spot where South and O'Hanlon lost their lives.
An annual lecture has been held in memory of O’Hanlon since 1982, and approximately 500 people attended a 50th commemoration of the men's deaths in January 2007 in Limerick.
