As I recall, Rocket's Red Glare runs at that scale.
Although designed for AWI, Andy Callan's "Loose Files and American Scramble" which can be found free on the net, could be readily used.
Sometime back I wrote a set called "Flames Across The Border" which I'd happily send you a copy of, if you contact me off-line. A friend of mine wanted to refight Crysler's Farm at 1:10 based upon Donald Graves' book. Me made up a 4X10' table of the correct terrain and I wrote up suitable rules utilizing every clever idea I had ever read of or seen in other sets, including an artillery bounce stick and variable movement distances. I was pleased with the results. We have refought Crysler's Farm, the Battle of York, and Queenston Heights, all on purpose-built terrain and all with reasonably accurate results. (Hint: charging a small unit of light dragoons across a muddy field against steady British infantry is NOT a good idea). Reconfiguring the same terrain has allowed us to refight Stoney Creek, Beaver Dams and Chateauguay.
I would probably trot these games out for this year's conventions except that everyone and their brother are putting on 1812 games and I figure that the market is saturated. I'm focusing on other periods for my convention games to attract those who are 1812ed out.
