The Battle of Vinegar Hill (Irish: Cath Chnoc Fhodh na gCaor), was an engagement during the Irish Rebellion of 1798 on 21 June 1798 when over 13,000 British soldiers launched an attack on Vinegar Hill outside Enniscorthy, County Wexford, the largest camp and headquarters of the Wexford United Irishmen. It marked a turning point in the rebellion, as it was the last attempt by the United Irishmen to hold and defend ground against the British military. The battle was actually fought in two locations: on Vinegar Hill itself and in the streets of nearby Enniscorthy.



The Irish Rebellion of 1798 (Irish: Éirí 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.
