Thats pretty much my biggest complain with this wonderfull game, i just annihilated the confederate army at antitam but i know that i lost more men than i regain through the victory reward and that i will soon face the army of northern virginia again.
This battly of antitam should have broken the back of Lees army. It bothers me, that I take the Lousiana Tigers prisoners, just to face a new three star Lousiana Tigers brigade in the next battle. There is no insentiv to motivate me to go behind the retreating enemy, to surround and destroy them, when they just respawn, i lose more men then absolutly needed and grow weeker because of it. When you have taken your points, doing nothing is the best course of action and that's a bit sad.
one unrelated question: do fleeing troups count as losses for the enemy?
