Red Bear Barbarossa 4

I need help on this level, my gens are Robinhood, Cleopatra, Hannibal, huo (forgot), Caeser, Alexander, and Li Shimin. I start by sending 2 armies, my "gold squad" aka Caesar, Alexander, and Li Shimin, and the rest of my troops go south. I focus fire on Genghis Khan in the north as much as possible, and I'm forced to sacrifice Caesar to kill him (which I think is worth it because he's an IAP, aka stronger than any other mounted soldier). In the south, I encounter jebe (the god mounted archer), and by turn 3, 1 castle is down, half my army there is dead, and my Ally's is almost gone. By turn 5, the second castle is gone. Turn 10, my army is dead besides coral and a horseman, and the godly, invincible jebe at my doorstep taking everything I own, and there, I give up, because I have no army left besides Li Shimin, and no way to build one... Meanwhile the Mongols are still going strong...
