In the second age, Orcs wandered to the far north of Middle-earth in search of a new home. This was when they attacked Mount Gundabad from the northern end of the Misty Mountains. By the Third Age, they had officially declared Mount Gundabad as their fortress leaving the dwarves seething with hatred against them. [1] Mount Gundabad remained the fortress of the Orcs until the War of the Dwarves and Orcs plowed down the mountain. However, during the events of The Hobbit, it is widely believed that a few Orcs came back to the mountain to defend it and started new construction works, in turn harming the wilderness of Mirkwood yet again. It was from this place the goblins came to the Battle of the Five Armies in huge numbers. The Orcs were led by Bolg, son of Azog as the supreme commander. He led them through the northern side of the Misty Mountains, more specifically Mount Gundabad. He was eventually slain by Beorn, the skin-changer. The Orcs army carried orcish scimitar, spears, and axes in the battle. Another theory related to the Orcs is that the Longbeards could have possibly taken back their ancestral homeland from the clutches of the Orcs since they had won back Khazad-dûm and the Reunited Kingdom in the Fourth Age.
