The Battle of Ballinamuck, fought on September 8, 1798, marked the decisive defeat of the French and Irish forces during the 1798 Rebellion. General Jean Joseph Humbert's Franco-Irish army, which had achieved initial successes in Connacht, was ultimately overwhelmed by superior British Crown forces led by Lord Lieutenant Cornwallis in County Longford. This engagement effectively ended the French incursion and the main phase of the rebellion in Connacht. The battle resulted in heavy casualties for the Irish rebels, with many killed and captured, while the French contingent surrendered. It is considered a pivotal moment in the suppression of the United Irishmen's uprising.
