Fall of Mount Gundabad
From Tolkien Gateway
The Fall of Mount Gundabad, took place after Eregion was destroyed.
After the doors of Khazad-Dûm were shut, Orcs, reinforced and commanded by the servants of Sauron, invaded Mount Gundabad and drove the Longbeard Dwarves from their holy site and dwelling. As a result, the Grey Mountains were infested and communication between Khazad-Dûm and the Iron Hills was cut off.[1]
