The Battle of Ballymore-Eustace was one of the events in the United Irish rebellion of 1798. It took place on 24 May 1798 after the stationing of the 9th Dragoons, and members of the Tyrone, Antrim and Armagh Militias at Ballymore in County Kildare near the Kildare-Wicklow border on 10 May. The town had been recently garrisoned by almost 200 soldiers and militia who had been sent to repress sedition in the area. The troops had been dispersed in billets among the populace as per counter-insurgency practice of "free-quarters" where responsibility for the provisioning and sheltering of militia was foisted onto the populace. During this time a quantity of arms were surrendered and letters of protection issued.
