The Great Western Battles book for Fire and Fury contains orders of battle and maps for:
Shiloh
Corinth
Stones River (Murfreesboro)
Champion Hill
Chickamauga
Atlanta
Many scenarios contain special rules and "what if" variations.
The designers suggest that players play no more than one corps each, as commanding larger forces "will slow down game play".
The scenarios can be used for other systems. Stand sizes are typically 200 men, turns are 30 minutes, and distances are 1" = 66 yards.
