Buhrdur

Buhrdur was a Hill troll chieftain that had been perverted to the Witch King's service under Rogash and Rogrog I. The trolls intimidated and enticed Buhrdur in joining the Angmar army. The three trolls would become mighty generals in the Witch King's army. But in the end, like Angmar, Buhrdur was slain by the combined forces of Rivendell, Lindon, and Gondor.
