Note!
Do not play as the 5th player! It's an AI. And everything related to it is designed for the AI.
When choosing factions, you are choosing based on the heroes, not the castles.
The castles are heavily fortified. See the screenshot in the first message.
Couldn't you just set up the desired players and assign the "Computer only" function to that player? (Scenario > Properties > Players > Type)
