Hand of Fate. Part 1: On the March

I understand that this is an old topic, but maybe someone will answer. I got to the mountains late (I delayed with the ship because I didn't see it available), and judging by what is written here, the Rogue should have a decent army. After the brown player started moving, I intercepted some hero in the mountains with a group of centaurs and attacked without looking. After that, I was told to approach the Necromancer, and according to the script, the mission ended. Question: was that the same hero? I have some feeling of frustration (I prepared, gathered troops, gained experience, and where is the final battle?). Apparently, I exhausted these partisans, and they died of hunger while waiting for me.
