This site has a good history of the Thirty Years War, with lots of of information about the various phases of the war — The Bohemian Rebellion, the Palatinate, etc.. Lots here that I never knew about.
If you’re interested in gaming the ThirtyYears War, there’s a post here about a set of rules for the period.
Rules writers pay attention! Mike Willegal has written an analysis of the effectiveness of black powder muskets.
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.
