When the numbers get uneven, the side with more troops takes the smaller side prisoner. Thus if you don't have enough men left to eliminate any more enemy and he cannot eliminate your troops, he is taken prisoner. It takes one man to guard 8 prisoners and march them to his own lines. If the guard is killed, escaped prisoners must escape to their own lines or fort before they can fight again. If they are attacked while escaping, however, they can defend themselves.
Musketeers can fire only if their guns are loaded that turn.
A cannon can fire grapeshot if it is its turn to fire. If not, the gunners must defend as light troops. Archers can turn up to 3 quarters of a circle to fire. Most other troops can be figured from the amount of armor they are wearing. It is very hard to break a castle walls.
