Army of Dol Guldur

The Dol Guldur Army was a large fighting force, comprised mostly of Orcs, but also of Trolls, Ogres, Goblins, Wargs, and Bats, which was led by Azog against Erebor during the Battle of the Five Armies.
== The Hobbit (film series) ==
The army was marshaled in secret at the command of the Necromancer in the cesspits of Dol Guldur under a spell of concealment, drafted mostly from the Moria Orcs that were loyal to Azog.
It was discovered by Gandalf, who was detained in Dol Guldur and only capable of alerting Erebor when the army was well on its way, marching through tunnels burrowed by Wereworms. It was a roughly 31,000-strong army, equipped with siege weapons (mounted over the backs of Trolls and operated by Goblins) and was engaged in fighting the Iron-Hill and Woodland armies in the Long Valley, while simultaneously using its superior numbers to breach Dale and engage the Lake-men army within the city walls.
It was finally defeated with the help of Thorin and Company, as well as the Great Eagles. Its defeat marked the end of the Battle of Five Armies, and nearly decimated the Orc population of Moria.
