So, now that I have a good amount of reasons for Britain pulling out, (Mutiny getting out of hand, King George butches it, public sentiment turns against him, no Nelson, internal problems) let's get to work on the Napoleonic invasion of America.
Napoleon, having set up French dominance on Europe, except for Russia, turns his eyes to a greater prize: North America. Purchasing Florida and Cuba from Spain, he then takes back French Control of Haiti, which leads to increased tensions with America. With America hastily updating her military in case of war, Napoleon decides to show to America that he is the dominate power in North America, and invades out of New Orleans. What's going to happen? Well, Napoleon would probably be using 30,000 men in the attack, with his most trusted and loyal troops, the Old Guard. He would have to end it quick, before Britain got involved, which is a given. Thus, he would have to recruit from Louisana and what not if he wanted to keep the campagin going. America would just have to hold out until Britain showed up, with maybe 10,000 men? Is that right? Anyway, the American military would be getting whipped for the most part, while Napoleon marches towards Washington. Andrew Jackson is charged with the city's defense. He thus builds a make shift defense on the edge of Fairfax county, manned by regulars, milita, and some cavarly. He is of course outnumbered, but has been able to build a pretty effective defense, with guerillas buying him time. Of course, the guerillas would be smashed. In the end, the Battle of Fort Jackson would be the key battle of the war, with Jackson holding out for as long as he can, while waiting for the British under Wellington to arrive. The formations involved are as follows:
France:
Two units of cavarly, 10,000 of the Imperial Guard, 150 cannons are various sizes, 2 units of infantry, (about 30,000)
America:
10,000 militamen, manning the fortifactions, 100 cannons, 5,000 cavarly, under Henry Lee, 5,000 regulars
The insueing battle is bloody for both sides, with Jackson's fortifactions proving very dangerous to both cavarly and infantry. The cannons are divided in two, with some used in the defense of the fortifactions, and others used to draw the French cannons fire. In the end, with the center on the verge of collapse for the Americans, Napoleon sends in the Old Guard, who charge straight at the Militamen, who now number about 7,000. Jackson personal leads the militamen against the Old Guard, using grapeshot to try to cut down their numbers as much as possible until they reach the milita,a nd his presence helps boost the moral of the milita. What ensues is a bloodbath, with the milita fighting for their lives. It's at this point, however, that Henry Lee launches an attack into the rear of the Old Guard, having driven off the cavarly. Meanwhile, the Regulars hold down the flanks, keeping some of the other infantry off Jackson's back. IN the end, the Old Guard are defeated. This concedes with the arrival of Wellington, who leads the British in a flank attack on the French. Napoleon is forced to retreat, pursed by the Anglo-American Alliance.
