Hint: Combining armies: Armies may be combined, especially if they are not
winning too many battles individually. Up to three artillery units
can be in a single army.
Hint: Avoiding Mexicans and Indians: Always stay away from the Mexicans. When Indian territory
is captured, move away.
Hint: Destroying enemy artillery: Hold Fire at the start of a battle for a better chance
to destroy the enemy's cannon. Also try to destroy the bridge
and stay out of the way of the infantry.
