|Other names||Bolg of the North|
|Date of death||T.A. 2941|
Bolg was the son of Azog, who succeeded his father as leader of the northern Orcs after Azog was killed by Dain II Ironfoot at the Battle of Azanulbizar in Third Age 2799. This started Bolg's hatred towards the Dwarves and after the Great Goblin was killed during an encounter with Thorin and Company in Third Age 2941, his hatred for them grew even more.
Battle of the Five Armies
Once they reached the Lonely Mountain, Bolg led the Orcs and Wargs into battle with the Dwarves, Wood-elves, and Lake-men. Surrounding him was a group of huge Orcs with steel scimitars. When Thorin Oakenshield attempted to pierce their ranks he became surrounded and died from his wounds. The Eagles arrived and after them came Beorn in the shape of a bear. Beorn killed Bolg and the Orcs and Wargs were soon defeated.
In The History of The Hobbit, a word from a little known and little expanded language, Mágol, is given, bolg, which means "strong". Tolkien at one time considered making Mágol an orkish language. An Ivernian word "bolg", of unknown meaning, is also cited by Rateliff.
