If you have a big force of Heavy Cavalry and not much else, you can use these units to throw back a much larger army. As soon as the battle starts, pause game play and assign each individual Cavalry unit to attack one unit from the enemy's side. Try to go for an even distribution if possible. After that, select all of your Cavalry units and resume game play, then order your men to run or to charge. The combined force of your Cavalry coming forward at a charge is enough to frighten most troops or throw them back. Your own casualties are usually light to moderate. Note: Do not try this if your squaring off against elephants, as you will not win.
