Just the stuff I was looking for

Thank you very much!
I've gotten the map from the vassal module and the counters from boardgamegeek, I just have to do a lot of printing and slicing and dicing now.
I've never played these things over the net, maybe someone could get me started? I'm a bit hobbled at my end though, I'm limited to access from a library and I doubt these machines are allowed to run any programs I try to load. I could transfer files though on to a thumb drive and then onto my machine at home, though it's a bit under memoried for vassal. It runs, but clunkily.
I've seen there's quite a large number of posts about the game series at consimworld.
Anywhere I can find the original rules for the series? I'd like to compare the two systems. Didn't Clauswitz or somebody like him write about warfare in terms of friction? Is that what the original rules tried to emulate?
Sincerely, Allan
