Iron and Steel are a set of free wargames rules for Victorian age naval battles.

Iron & Steam is based on a set of Victorian pre-dreadnought rules written by a friend in the late 1980s. They’ve evolved over the years though I’ve not played them recently. The game is meant to use sheets for each ship to record movement orders and accumulated damage. I had a fairly complex set up of mail-merged MS Word documents to generate the record sheets. But, of couse, they no longer function so I’ll have to come up with another system of generating them. That may take a while. Still… the game is playable if you’re willing to keep track of the statistics on a piece of paper. I know, I know… so high tech…. The methods of calculating the factors and a number of pre-calculated ships are included in the rules.
