The Battle of Vinegar Hill (Irish: Cath Chnoc Fhíodh na gCaor), was an engagement during the Irish Rebellion of 1798 on 21 June 1798 when over 15,000 British soldiers launched an attack on Vinegar Hill outside Enniscorthy, County Wexford, the largest camp and headquarters of the Wexford United Irish rebels. It marked a turning point in the rebellion, as it was the last attempt by the rebels to hold and defend ground against the British military.
