Gundabad Orcs

The Gundabad Orcs are Orcs inhabiting Mount Gundabad. They attacked the mountain and took it from the Dwarves of Durin when they had dwelt there. They were the servants of the Witch-king of Angmar before they had seized Gundabad.

History
Some time during the Second Age, the orcs that had survived the destruction of Angband were forced to wander the Northern Waste and find a new home. This was when they attacked the mountain and took it from the Dwarves. In the Third Age,

the Orcs of Angmar officially stated Gundabad as their capital which angered the Dwarves greatly. Gundabad remained an Orc stronghold, until it was cleared of orcs in TA 2799, after the War of the Dwarves and Orcs. However, small groups of orcs must have returned and fortified it anew during the events of The Hobbit, menacing Wilderland once again. It was from here that the Goblins present at the Battle of the Five Armies came from in their marching numbers. Their leader, Bolg, son of Azog, was the supreme commader of the orcs from Mount Gundabad and presumably the northern Misty Mountains and was killed by Beorn, the skin-changer. It is unknown what became of the orcs after that or who their leader was but some say they eventually left Gundabad and settled in the Misty Mountains.

Appearance
The Gundabad Orcs had appearance similar to that of the Orcs of Mordor, the footsoldiers of the Dark Lord Sauron. They had dark skin, fangs, claws, and a small amount of hair. They wore armor of brown and white fur coats threaded with various beast's teeth and sharp shields bearing the Iron Crown. They, like many orcs, used long sharp swords called Scimitars with which they impaled and slashed their victims.

Portrayal in Adaptations
In The Lord of the Rings: The Battle for Middle-earth II: The Rise of the Witch-king the armies of Gundabad are divided in two units, Gundabad Warriors which wore shields and scimitars and Gundabad wolf riders which rode huge Dire wolves. One battalion of each was commanded by a Thrall Master of Angmar. In a deleted level of this game the election of a leader is also described. Even though each orc tribe had a chieftain all the orc tribes were united under one leader. If this leader died the chieftain of the tribes would dispute the place of leader in a competition that consisted in killing goblins.

In The Hobbit: An Unexpected Journey, Azog (and possibly also his hunters) is from Gundabad.
