Battle of New Ross: The attempt to spread the United Irish Rebellion into Munster is defeated.

The Battle of New Ross was a military engagement which took place in New Ross, County Wexford during the Irish Rebellion of 1798. It was fought between the Society of United Irishmen rebels and government forces garrisoning the town. The attack on the town of New Ross on the River Barrow, was an attempt by the recently victorious rebels to break out of county Wexford across the river Barrow and to spread the rebellion into county Kilkenny and the outlying province of Munster.

The Irish Rebellion of 1798 was a popular insurrection against the British Crown in what was then the separate, but subordinate, Kingdom of Ireland. The main organising force was the Society of United Irishmen. First formed in Belfast by Presbyterians opposed to the landed Anglican establishment, the Society, despairing of reform, sought to secure a republic through a revolutionary union with the country's Catholic majority. The grievances of a rack-rented tenantry drove recruitment.

Munster is the largest of the four provinces of Ireland, located in the south west of the island. In early Ireland, the Kingdom of Munster was one of the kingdoms of Gaelic Ireland ruled by a "king of over-kings". Following the Norman invasion of Ireland, the ancient kingdoms were shired into counties for administrative and judicial purposes. In later centuries, local government legislation has seen further sub-division of the historic counties.
