General Jean Joseph Amable Humbert, a French soldier and participant in the French Revolution, and who leads a failed invasion of Ireland to assist Irish rebels in the Irish Rebellion of 1798, is born on August 22, 1767, in the townland of La Coâre Saint-Nabord, outside Remiremont in the Vosges department of northeastern France.

Humbert is the eldest of six children of Jean-Joseph Humbert, a farmer and trader, and Catherine (née Privat), who dies when he is three years old. From a modest rural background, he works briefly as a hatter and rabbit hunter before entering the military in July 1789 amid the early stages of the French Revolution.

Humbert joins the National Guard of Lyon and quickly advances, serving in the 13th Battalion of Volunteers of the Vosges. By 1792, he is promoted to captain, then lieutenant-colonel. His combat record includes service under General Lazare Hoche in the Army of the Rhine and Moselle, where he gains a reputation for bravery and guerrilla tactics.

In 1796, Humbert is assigned to prepare for an expedition to Ireland. In the ill-fated Expédition d’Irlande, his ship Droits de l’Homme is wrecked off the Bay of Audierne in January 1797, but he survives. In 1798, he leads about 1,000 French troops to Ireland, landing at Killala. His forces fight and win at Ballina and the Races of Castlebar, proclaiming a Republic of Connacht before being defeated and captured at the Battle of Ballinamuck. He is exchanged for British prisoners.

Humbert continues to serve in the French Revolutionary and Napoleonic armies, participating in the Swiss campaigns, the Saint-Domingue expedition, and the Argentine War of Independence. He also engages in filibustering ventures against Spanish holdings in Texas, Mexico, and Buenos Aires.

In 1810, Humbert emigrates to New Orleans, where he becomes acquainted with French pirate Jean Lafitte. He joins the Buenos Aires rebellion in 1814 before returning home. In 1815, he fights the British at the Battle of New Orleans in the War of 1812, earning thanks from General Andrew Jackson. He later lives as a schoolteacher in New Orleans until his death on January 3, 1823.

Humbert’s career spans revolutionary France, Napoleonic campaigns, and post-Napoleonic adventures, making him a notable figure in late 18th- and early 19th-century military history.
