As compensation from losses elsewhere, France handed over control of New Orleans and all the land on the west bank of the Mississippi River and its tributaries to their Spanish allies.

After a mass meeting in January 1765, Jean Milhet, a rich and influential New Orleans merchant, was sent to France to appeal directly to Louis XV to rescind the decision to transfer Louisiana to the Spanish crown, but the King would not grant him an audience.

[3] Having insufficient military support if there were to be an insurrection, he did not present his credentials and did not formally accept the handing over of the territory, not even raising the Spanish flag over the Place d'Armes.

[4] Ulloa finally took formal possession of the colony in late January 1767, in an impromptu ceremony held at La Balize, Louisiana; however, he changed his mind the next day when it came time to sign the act of transfer, saying he would wait to do so when he had sufficient military support on hand.

[5] Ulloa's superiors in Havana virtually ignored his many requests, including to replace the colony's French currency with pesos and the dispatch of more soldiers.

[6] In the summer of 1768, Ulloa announced plans to crack down on Louisiana's considerable smuggling operations by reducing the mouth of the Mississippi to a single channel to improve security; officially he spent his time at La Balize supervising the engineering of the project.

[5] At the same time, he also announced that Louisiana would no longer trade with other nations, including France and any of its colonies, consistent with policy in other Spanish possessions.

Among the other trade policies enacted at the time were a ban on the importation of French wine and a requirement that Spanish sailors make up the majority of all ships' crews.

[7] In the spring or early summer of 1768, Denis-Nicolas Foucault, who was Louisiana's commaissaire-ordonnateur — the chief financial officer of the colony — under the French, and had continued the position under the Spanish during the transition, and Nicolas Chauvin de La Frénière, who was the Louisiana attorney general under the French and also continuing under the Spanish, hatched a plot to force the governor out.

In the process, the conspirators arrested the French military officer Gilbert Antoine de St. Maxent on charges of collaborating with the enemy when Governor Ulloa sent him to the German Coast to reassure the settlers there.

[9] On October 28, as riots broke out in New Orleans, Aubry escorted the governor and his pregnant wife to the Volante, the flagship packet boat on which he had arrived in the colony.

The Superior Council drew up the Memorial of the Planters and Merchants of Louisiana on the Revolt of October 29, 1768, a defense of their actions based on Ulloa's supposed tyrannical rule and the commerce-destroying policies of the Spanish crown.

The following morning, Aubrey assembled the people of the city, formally announcing the arrival of a Spanish armada of ships commanded by General O'Reilly, whose reputation was well known to them.

O'Reilly disembarked on August 18, having previously met with Aubrey to tell him that he wished to hold the ceremony of taking formal possession of Louisiana as soon as he arrived.

Aubrey read out the transfer orders from the kings of France and Spain, and laid the keys to the city's gates at O'Reilly's feet.

[17] The next morning, August 19, O'Reilly requested of Aubrey a full account of the rebellion, providing the names of the ring-leaders and their deeds, and the authors of the 'Memorial of the Planters and Merchants'.

The administrative and judicial systems were overhauled, and the courts were decentralized, putting local justices in place and abolishing the Superior Council, the members of which were largely responsible for the rebellion.

In April 1803, Napoleon sold La Louisiane to the United States in the Louisiana Purchase, in exchange for money and the cancellation of French debts.
