All questions regarding mapmaking for Heroes of Might and Magic 3: The Shadow of Death.

I can't understand why the computer is so "cowardly."
In the "Specifications," I marked all the opponents as "warriors,"
gave them ready-made armies and artifacts. I don't know what else to do,
how to make them fight?
I have the weakest army (the red one), and the enemies run away from me, giving up their cities.
I specifically placed border gates so that they couldn't take all their cities.
So, these idiots are hiding from me behind these gates – it's some kind of absurdity!
