Philip Haythornthwaite’s The Napoleonic Sourcebook is a good place to start for a basic understanding of the Napoleonic Wars. The volume is divided into six major sections: The Campaigns, Weapons and the Practice of War, The Nations Involved in the Wars, Biographies, Sources, Miscellaea and a useful glossary. There are more than 200 black and white illustrations, maps and charts. For the painter, the book has descriptions of various uniforms and lists of uniform, facing, hat and button colors.
Column, Line and Square was the first set of Napoleonics rules that I ever played — and I suspect, the first set that many people played. We called it Column, Line and Slaughter, though, becuase slaughter was the usual result.
Still, it was fun to play –especially with 25mm figures.
Sadly, the set is apparently no longer in print. But you can get the rules here, free for the downloading.
