1-5 are different units. a is for attack, this moves all units forward a bit. r is for retreat, this moves all units back a bit. use the arrow keys(except down) to move a new unit to a corresponding base. g is for left and h is for right. 1=brigade, 2=regiment, 3=skirmishers, 4=company, and 5=cannon. once there r no more enemy units u win!
i made this entire project myself.
