I assume they did this so you don't get the achievement and reload an earlier save to keep Fasolt alive. With the king refusing to destroy the bridge leading to the fortress, the companions have no choice but to fight the Dredge, leading to Iver being severely. IMPORTANT: This achievement does not unlock until the end of the game when the credits roll, so don't worry that you don't get it after the bridge is destroyed. After the battle, he confronts Jorundr, who will finally agree to let you destroy the bridge. You learn that Fasolt died the day before, and he will be replaced by Iver who is now healthy, and furious. The third day is where you are forced to fight. The second day, you can fight or clear the bodies - if you're trying to keep Egil alive, make sure you fight, otherwise it doesn't matter which you choose for this specific achievement. The first day, you can participate directly in the fight or treat the wounded, it doesn't change anything which you choose. Make sure you choose to fight on the bridge. After you arrive in Einartoft (and after Iver is defeated by Bellower), you will have a few options: destroy the bridge, fight on the bridge, or leave.
