General Jean Joseph Amable Humbert was a French military officer who participated in several notable military conflicts of the late 18th and early 19th century. Born in the townland of La Coâre Saint-Nabord, outside Remiremont Vosges, he was a sergeant in the National Guard of Lyon. He rapidly advanced through the ranks to become brigadier general on 9 April 1794 and fought in the Western campaigns before being allocated to the Army of the Rhine. Humbert also participated in the United Irishman Rebellion and the War of 1812.

The Irish Rebellion of 1798 was a popular insurrection against the British Crown in what was then the separate, but subordinate, Kingdom of Ireland. The main organising force was the Society of United Irishmen. First formed in Belfast by Presbyterians opposed to the landed Anglican establishment, the Society, despairing of reform, sought to secure a republic through a revolutionary union with the country's Catholic majority. The grievances of a rack-rented tenantry drove recruitment.
