It is possible to restore the hero's morale to its normal value.

Yes, everything is fine now. Apparently, after Bertrand, I was a bit overwhelmed.

Today's battle was very amusing, Varnes against Fernando.
This Fernando is a very active guy, and he kept casting dark magic. At first, I regretted not taking the weakness to darkness. He kept casting berserk and enslave, my archers suffered and were humiliated, and in general, I decided not to use them at all.
After the battle, I had 296 lendlords and 30 adepts left. The losses were minimal.

In general, the 4th mission is very dynamic. In this month, which is given to meet Arantir, I managed to take 2 castles, run around all the resources, collect them, and capture several dwellings, and give a good beating to Bertrand and his supporters, who are sitting in the northeast in a castle.
Let's see what happens next.
