So, a lot of stuff to unpack with this rumor mill. With the Spanish-American pact, the two great powers based in the Americas (France and Portugal have Haiti/Caribbean and Brazil, respectively) have committed to expelling British influence from the western hemisphere. Brazil is the only pro-British (aside from Caribbean colonies) territory left, and we have no idea how much it's population wishes to remain under Portuguese rule. The Spanish Empire is still bringing all their territory to heel, so they can't afford to invade Brazil, plus there's that little issue of the Treaty of Tordesillas, which is the legal and religious basis for why the Spanish and Portuguese colonies in the Americas, Africa, India, and SE Asia and the Philippines turned out as it did.
Then there's the mention of the three legendary figures, Washington, who is on his deathbed nearly three years early, Brian, who has pulled off some crazy military and diplomatic bullshit, and Lafayette, the Hero of the Two Worlds. Interestingly enough, back during the Frankfurt conference, we had the option to meet him while in Frankfurt. This is super interesting, as he had fled from the Jacobins in France in 1792 to the Austrian Netherlands in an attempt to get to the US. In turning himself and the other officers over to Austrian officers as part of surrender negotiations, the noble in charge recognized Lafayette and had him imprisoned as a dangerous revolutionary, rather than an officer under negotiations. He wasn't released in OTL until Napoleon, then consul, bought his release from the Austrians. However, there had been an American plot involving a Alexander Hamilton's sister-in-law Angelica Schuyler Church and her husband, John Barker Church, a British member of Parliament who had served in the Continental Army. They hired a Hanoverian physician, Justus Erich Bollmann, who took on an assistant from South Carolina, Francis Kinloch Huger (the son of Benjamin Huger, who Lafayette stayed with upon his first arrival in America). They managed to help Lafayette escape from an escorted carriage drive from his prison at Olmutz, but he got lost and was recaptured. In this timeline, his escape must have been successful, since he was released in late September 1797 as a result of the Treaty of Campo Formio.
Another thing that happened was Jules Leo Severin being promoted. With his colonelcy, he is now the head of the Haitian Foreign Legion, and between the flavor text of prior rumor mills and his on, unrestricted recruitment policies, he is essentially in charge of the one of the few military unit that accepts free blacks and former slaves. He is suddenly very politically relevant in what is to be the newest province of France.
