James Corcoran (c.1770 – 1804) was an Irish rebel who fought during the rebellion of 1798 and was the leader of the last rebel guerrilla band to be defeated in the years following the suppression of the rebellion.
Corcoran played an active part in the rebellion and led a party of rebels at the battle of New Ross. Following the collapse of the rebellion, he and a group of survivors established a base in Killoughrim Woods, north county Wexford from where they launched raids in the area and into county Carlow. In August 1801, an upsurge in Corcoran's activities saw him and his men being declared "dangerous in case of invasion" by Dublin Castle and consequently, a force of 200 soldiers was sent to find and destroy the group. However, they met with little success as the populace shielded them from the military.
Corcoran's men were distinguished by their willingness to allow deserters from the military in their ranks and actively sought to subvert soldiers billeted among the populace or at least rob them of their arms. Their fearlessness was demonstrated in an incident near Mount Leinster in June 1802 when they turned to attack a number of pursuing Newtownbarry yeomen who were defeated and soon under pursuit themselves.
The defeat of Robert Emmet's rising in July 1803, saw renewed British intent to wipe out all remaining rebel activity in Ireland and new campaign was launched against Corcoran. This time account was taken of the fact that Corcoran's men enjoyed support from the population in areas where they operated and also that their permanent bases were in remote localities. Consequently, arrests and severe penalties were handed out to those suspected of harbouring rebels, and the building of military roads and barrack were planned to cover the area between Mount Leinster and the Blackstair mountains.
The surrender of Michael Dwyer in December 1803 left Corcoran and his men as the only rebel faction still active in Ireland as 1804 began. The ongoing military offensive by now had forced Corcoran to relocate to south Kilkenny from where they continued operations and incensed the government by targeting their mail coaches. A reward of £500 was put on Corcoran's head and the pressure soon forced him to split his group into smaller factions and return to his old base at Killaughrim woods outside Enniscorthy. The end finally came in February 1804 when the reward prompted an informer to betray the location of Corcoran and he and his remaining comrades were surrounded by a party of yeomen. After fierce resistance all of the unit were killed or captured, Corocran dying of his wounds shortly after the fighting. His body and that of his comrades were brought to Wexford where they were hung outside the town gaol and left on display for a time.
