Excellent game and AAR.
One question, is there any significance in the round "command" bases in your rules? I only ask as a friend, Tim Elcock, has been writing his own ECW rules for some years (as well as working on a rough draft for the Too Fat Lardies), and has - quite independently - come up with round command stands for his regiments. I can't quite recall what significance they have in his draft rules, but it does allow him to change the identity - and even the allegiance - of a regiment just by substituting a different command stand.
