Hello and sorry if there has been a thread about this already. Having attacked quite many players already I've noticed that used unit is a dead unit even if it's not dead when you're done attacking. I would like to see (somewhere in the future) a possibility for building a hospital of some kind on your island where your troops who didn't die in the battle go to recover for example half the price it would cost to rehire them. Maybe the recover time would take longer than what it would take to hire but not cost so much.
Or perhaps cost twice usual price (compensation for battle trauma) but half/no recruitment time - since they're still already on your ship! (assuming they could swim back to your ship after the battle).
