The Battle of Castlebar was a military engagement of the Irish Rebellion of 1798, which occurred on 27 August 1798 near the town of Castlebar, County Mayo. A combined force of approximately 800 French troops and 2,000 United Irishmen rebels, commanded by Jean Joseph Amable Humbert, routed a British Crown force numbering from 3,000 to 5,000 men, led by Gerard Lake, 1st Viscount Lake, in what would later become known as the "Castlebar Races" or "Races of Castlebar". During the battle, the French, although they had veterans in the ranks, fought in an exhausted state after long mountain marches, and the United Irishmen were exhausted for the same reason; Lake's army was in an advantageous defensive position but at the same time had a significant number of untrained Irish militiamen in their ranks, which were routed in the face of the Franco-United Irishmen assault. Lake's army included such regular regiments as the Fraser Fencibles, Roden's Fencible Cavalry Dragoons, the 6th Regiment of Foot and the Royal Irish Artillery; all four were engaged at Castlebar and, though fruitlessly, they offered serious resistance, in contrast to the militia regiments.
