Lord of the Rings: Battle for Middle Earth help

[amazingfantasy15]

Does anyone have any advice for the Erebor Level (Evil Campaign) in Lord of the Rings: Battle for Middle Earth? I keep getting totally destroyed, I'm barely hanging on, then they mention King Dain, building start going up in the middle of my camp and it's all over.
