When your city is attacked some of your troops will get wounded and be sent to the hospital, if you hospital Is full the wounded troops die. Depending on how strong the enemy attacker is you will either win the battle or loose the battle. If the enemy runs out of fresh troops they are forced to retreat back to their city.
