During the 1730s, the French Navy in the Caribbean played a significant part in policing the slave trade out of Port-au-Prince; as a result, a large number of French vessels were sunk by the pirate vessel Experto Crede, captained by the Assassin and ally of the Maroon rebellion, Adéwalé, who had also previously sunk a French Treasure Fleet commanded by a Templar Admiral.
During the Seven Years War, the ships of the French Navy were allied with the Colonial Assassins, helping them to secure control over the North Atlantic while fighting the British Royal Navy. Two of the French Navy's most powerful ships controlled the North Atlantic, the Couronne and the Formidable, but the Royal Navy Privateer and Templar, Shay Cormac, managed to sink these ships and cripple their naval power with his ship, Morrigan.
In 1776, before France openly joined the American Revolutionary War, the French navy secretly transported supplies for the Continental Army with ships repainted and renamed to appear Spanish. One of these ships, La Belladonna, was escorted through the Caribbean Sea by the USS Randolph before being abandoned. The Aquila resumed her escort and defended her when Nicholas Biddle alerted a British Man O' War to her location.
Two years later, General John Sullivan caused a scandal when he wrote a letter criticizing the French's withdrawal at the Battle of Rhode Island. The Colonial Assassins' leader, Connor, sent his recruits to convince Admiral d'Estaing to ignore Sullivan's comments.
In 1781, the Aquila aided the French against the Royal Navy during the Battle of the Chesapeake. In return, Connor asked Admiral de Grasse to send a fleet, disguised as British ships, to bombard New York's militarized district, allowing him to infiltrate Fort George and assassinate Charles Lee.
