Well, what Americans lump together as the War of 1812 was two seperate and distinct engagements. There was the fracas on the Northern front that involved burning a few towns and was settled by the Treaty of Ghent; as people say, even a modicum of sense on either side could easily have averted this. And there was the Battle of New Orleans, which American high school textbooks sheepishly admit was fought after the Treaty but decline to say why. The reason was because Napoleon had no legal right to sell the place and Britain had taken it into their heads to play international policeman and return the place to its rightful owner (Spain). This is much harder to avert...the Americans are going to snag New Orleans one way or another, and Britain will almost certainly try to do something about it. But you can trim the War of 1812 With No Russians In It down to one battle (I honestly doubt the British are peeved enough about it to try a large invasion).
