You need to save before the first battle, otherwise it's inconvenient to wait 2 minutes if things go badly.
I'm replaying, I'll make the general the main one, I think it won't be possible to win without defeating the army in a direct battle, or the losses will be too great, and only he can defeat it.
As usual, I was testing on Veteran difficulty, knowing all the nuances and dependencies of the enemy's strength on the player's actions. I weakened the enemies several times. Perhaps this is still not enough, and I will have to weaken them even more.
