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

The Irish Rebellion of 1798 (Irish: ir Amach 1798; Ulster-Scots: The Hurries) was a major uprising against British rule in Ireland. The main organising force was the Society of United Irishmen, a republican revolutionary group influenced by the ideas of the American and French revolutions: originally formed by Presbyterian radicals angry at being shut out of power by the Anglican establishment, they were joined by many from the majority Catholic population.

Following some initial successes, particularly in County Wexford, the uprising was suppressed by government militia and yeomanry forces, reinforced by units of the British Army, with a civilian and combatant death toll estimated between 10,000 and 50,000. A French expeditionary force landed in County Mayo in August in support of the rebels: despite victory at Castlebar, they were also eventually defeated. The aftermath of the Rebellion led to the passing of the Acts of Union 1800, merging the Parliament of Ireland into the Parliament of the United Kingdom.

Despite its rapid suppression the 1798 Rebellion remains a significant event in Irish history. Centenary celebrations in 1898

were instrumental in the development of modern Irish nationalism, while several of the Rebellion's key figures, such as Wolfe Tone, became important reference points for later republicanism. Debates over the significance of 1798, the motivation and ideology of its participants, and acts committed during the Rebellion continue to the present day.

The Battle of New Ross took place in County Wexford in south-eastern Ireland, during the Irish Rebellion of 1798. It was fought between the Irish Republican insurgents called the United Irishmen and British Crown forces composed of regular soldiers, militia and yeomanry. 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.
