I think there are some good books by Mike Blake? One of the guys
who wrote the wonderful Western Gunfight rules. I would like to
see what answers you get, as I fancy doing some (early) Apaches
versus Mexicans. I was thinking of using some of the very nice
Boot Hill miniatures (Alamo range) for the Mexicans, but at a loss
for Apaches with lance, shield & bow. I recall some promise of
such figures here on LAF, but so far I have seen nothing definite.
