Battle of Castlebar

Castlebar, County Mayo, Ireland

What happened

French troops under General Jean Humbert and Irish rebels of the United Irishmen fought a British army under General Gerard Lake. During the Irish Rebellion of 1798, a small French force landed in County Mayo to support the United Irishmen. Joined by local volunteers, they attacked the British at Castlebar early in the morning. A French bayonet charge unnerved the British troops, many of whom fled so fast that the battle became known as the 'Castlebar Races'.

Why it matters

Why it matters: The victory brought thousands of Irish volunteers to the rebellion, and a short-lived 'Republic of Connacht' was declared. It lasted only 12 days.

What came next

Humbert surrendered at Ballinamuck on 8 September 1798, effectively ending the rebellion. Two years later, the Act of Union merged Ireland's parliament with Britain's.

Did you know?

General Lake's personal luggage was left behind in the retreat, and some fleeing troops did not stop until they reached Athlone.
