Blood Sweat & Iron is a simple American Civil War Ironclad river actions rule set, it uses a very simple combat system to allow you to play battles within a couple of hours. The system uses datasheets for each ship in the game, all are at the back of the rules ready for you to print out and use. It is meant to be a fun game that offers the players a feel for the river battles of the era, this is not meant to be a true historical simulation. There are no huge charts needed to play as almost everything you need is either on the ship’s datasheets or on a Quick Reference Sheet, all tokens are supplied as well. The rules cover over eighty ships of the time, plus a few extras to add to your games like shore forts, barges and fire rafts etc. etc. —description from the publisher
