The Mexican Adventure rules

 https://www.scribd.com/document/268856747/Mexico-Rules

The rules provide gameplay mechanics for wargaming battles involving Maximilian's forces in Mexico in the 1860s. Troop types and weapons are diverse, so morale class determines actions and abilities. A unit's morale class affects actions, firing, melee, and morale tests. Movement, firing, melee, and morale rules are outlined. The backbone is alternating turns with charge declarations, actions, melee resolution, and morale checks.
