There were three quests in total for the battle against the Count of Basel.
They involved capturing Baron Landschaft, the lord of Birsfelden, and the Count of Basel. For Baron Landschaft and the lord of Birsfelden, the rewards were 10,000 points and 100 gold coins each, the same as for the lord of Hagenhausen.
The Count of Basel was worth 50,000 points and 500 gold coins, the same as the lord of Wischelbach, but I boldly gave that one up. Plundering the region was essential to acquiring the Gale Plunderer trait.
If the state of the war had been such that I absolutely had to capture the Count of Basel to win, I obviously would have grabbed him, traits be damned. But it was a complete victory for me, and the Count of Basel had simply holed himself up in his castle.
