On the first level of the Confederate Army on the road, go right before the bridge to find a fence. Walk up the fence line tapping A and pick up the Gatling gun which has unlimited ammunition. Unless you save before you die you will have to do this cheat again.
When in a battle and on your last unit, make it move as far as it will go for your first turn and click fast anywhere for your second turn. While they are moving, your first unit moved will get a #1 mark in its area. Click it, and it will move again. Repeat clicking to move to an enemy unit and kill it. Note: If your first unit dies, you cannot use this trick in that battle.
