Sorry for not replying earlier, but I have been on the go with work committments that took me interstate.
Firstly, The rules we used were, "Lance and Sabre." A set of rules which I'm still developing.
The Muster was held in Brisbane, Australia. I actually work in Melbourne, but Brisbane is my home town.
Who won?
Just like in all good cavalry movies, just when the Indians looked like they would overpower the small garrison. In the distance was heard, the lone trumpet of the releif column.
The Defender threw 12 on 2D6, making the Indians withdraw.
