The Dade battle posting was pretty popular so I will try and feature more of this colourful era. This book looks the place to start - Richard Hook is a brilliant illustrator and knows Native American material culture better than anybody I know. I met him once - he's a friend of a friend and he's a very knowledgeable bloke. When they started work on the film of Last of the Mohicans the producers summoned him to London to meet Daniel Day-Lewis but in the end he didn't get to work on the movie but knowing what movie makers are like they probably just bought loads of copies of his Eastern Woodlands Osprey.
Anyway if any of you know of any good wargames or other links for the Seminole Wars get in touch.
