Ok here is the thing. I have my archers in the middle with infantry on both flanks and in front of them. On the back i have two units of cavs. So basically they are super defended. But when enemy cavelary charges my infantry , the archers run backwards (instead of just staying where they are and keep shooting) I tried guard mode in the hope they would stay but they wouldnt. What is the magic button i have to push to let them stay and keep shooting those damn mongols, because i just want to keep them to stand and shoot even when mongols are near and they might hit some of my own.
