Age of Strategy Forums

I have been playing this game for years. When I get to one that I can't beat, I come back later. I have come back to this one, until I only have a few that I can't get. This is the easiest one that I have, which I can't beat. Obviously, my strategy is all wrong. I have no idea what to do to survive even a few turns. Help please?

In this map, you can't defence behind walls.You need to put most of units to destroy emeny trebuchet and longbowman first. Then you use remain cavalry to kill crossbowman.
