The British Battles website has accounts, maps and orders of battle for dozens of famous battles involving the British army. Included are Battles from King George’s War, the Jacobite Rebellion, The French and Indian War, the American Revolution, the Peninuslar War, and other Napoleonic Era battles. It’s an incredible resource for the miniature wargamer.
When I first started playing Napoleonics, I was lost. There were so many characters and places and battles and politics and subterfuges. I enjoyed moving the lead around, but it was years before I felt I understood the greater background. If you want to break in a newbie, point him to this site.
Dave Ferris offers Napoleon at Chattanooga, a print and play boardgame that simply has to be described by the author himself:
Napoleon at Chattanooga: Boardgame of Napoleon’s famous campaign in the Tennessee Valley, conquest of the Solar System, and an armoured regiment named Bob. Some assembly required. My most successful boardgame design. 420K zipped archive includes maps, counters (must be glued to cardstock and cut out), charts, rulebook, and errata.
The classic board game Napoleon at Waterloo is readily available as a print-and-play, do-it-yourself, project.
