Expédition d'Irlande

LOADING MAP TELEMETRY…

Overview

The French expedition to Ireland, known in French as the Expédition d'Irlande, was an unsuccessful attempt by the French Republic to assist the outlawed Society of United Irishmen in their planned rebellion against British rule during the War of the First Coalition. France intended to land a large expeditionary force in Ireland during the winter of 1796–1797 which would join forces with the United Irishmen and overthrow British rule in Ireland. The French anticipated that a successful invasion would not only be a major blow to British morale, prestige and military effectiveness but allow for Ireland to serve as a staging point for an eventual invasion of Britain. In late 1796, the French Directory gathered a force of between 12,000 and 25,000 French Revolutionary Army troops at Brest under General Lazare Hoche in readiness for a landing at Bantry Bay in December.

Significance

The Expédition d'Irlande was an attempt by the French Republic to open a second front against Britain by landing between 12,000 and 25,000 troops in Ireland to join forces with the United Irishmen and overthrow British rule. France anticipated that success would deal a major blow to British morale, prestige, and military effectiveness, and would position Ireland as a staging ground for a subsequent invasion of Britain itself. The expedition's failure — costing France some 2,230 casualties — foreclosed that strategic opening and left the United Irishmen without the external support their planned rebellion depended upon. Within the broader War of the First Coalition, the episode underscored Britain's continued strategic vulnerability on its western flank while also demonstrating the limits of French power-projection in the face of operational difficulty.
