Aghrim, Or Anghrim, a village in the county of Galway, Ireland, 30 m. E. of Galway, famous for the crowning victory of William III. over James II., July 12, 1691. The marquis St. Ruth, a French general, commanded the forces of James 25,000 strong, while Ginkel led those of William, 18,000. St. Ruth had made able dispositions for the battle, but, jealous of the Irish generals, had kept his plans to himself, and when he was killed by a cannon shot early in the action there was no one to succeed him. The English troops, in spite of the well chosen position of their opponents, compelling them to advance through a deep bog, totally routed them, killing, it is said, 7,000, and taking 450 prisoners, while their own loss was only 1,700 killed and wounded.
