Notes on 1846 Mexican-American War

• for each casualty on a stand, minus 1 from the close combat die roll
• Only U.S. Volunteer Cavalry, U.S."Mounted Rifle" regiment and Mexican Irregular Cavalry May fire dismounted or mounted. All other cavalry has no fire.
• Only One section of heavy guns per army.
• Mexican artillery may never move and Fire. It moves OR it fires.
• We have found it neccesary for the Mexicans to have a 3-1 superiority in numbers over the Americans if they are attacking. On the defense, they need a 2-1 superiority for a balanced game.
• In our experience, the Mexican side will win aproximately 35% of the games. But when they do, victory is sweet!
