Background and detail

Background. Spain had acquired Louisiana from France by the secret Treaty of Fontainebleau of 1762, and formally announced the acquisition in 1764. Antonio de Ulloa became the first Spanish governor in 1766, but a pro-French rebellion in 1768 forced him to abandon the province, prompting Spain to send an expeditionary force under O'Reilly in 1769.

O'Reilly's Commission. Appointed Governor and Captain-General of colonial Louisiana while in Spain in April 1769, O'Reilly received orders to proceed immediately to Havana, embark 3,000 troops there, put down the revolt in Louisiana, and re-establish order.

Aftermath. Having crushed the ringleaders of the Louisiana Rebellion of 1768, O'Reilly sent most of his troops back to Cuba. In December 1769 he assigned the governorship to the Colonel of the Havana Regiment while retaining the post of Captain-General for himself, before returning to Spain in 1770.
