Battle of the Thousand Caves
This article describes a concept which is mentioned in J.R.R. Tolkien's works, but was never given a definite name.
|Battle of the Thousand Caves|
|Date: F.A. 503|
|Place: The Elven city of Menegroth|
|Outcome: Dwarven Victory|
The Silmaril that was rescued by Beren and Lúthien remained in the treasury of Thingol of Doriath who desired to have it always at hand. In the last years of Hurin's life he brought to him the famed Nauglamir, the Necklace of the Dwarves, from Nargothrond.
Having the two great treasures, he decided to unite them by fastening the Silmaril into the Dwarven necklace. The Dwarves that made that work desired the Silmaril from the beginning, and when the work ended they refused to give it to him. In the conflict Thingol was killed. The rest of the Dwarves were hunted down and slain as they fled home, and Nauglamir was taken from them.
Two Dwarves survived the slaughter, and made it to their home of Nogrod in the Blue Mountains. They lied saying that Thingol killed the Dwarves that made the Nauglamir, refusing to pay them for their work. Their kinsmen were enraged hearing these news, and decided to avenge their fallen artisans. Although the Dwarves of Belegost refused to aid them, they formed a great host. They entered Beleriand, and, crossing Aros, marched west towards Doriath. Nothing could stop them, as the Girdle of Melian waned after Melian departed.
The Sindarin captains were intimidated by the Dwarven host, and they scattered without hope.
 The Battle
The Dwarves found resistance only by the Sindar inside Menegroth. The losses were heavy on the both sides during the grievous battle. Mablung was defending the treasury where the Nauglamir lay, and there he was killed before its doors, and the Silmaril was taken. After they plundered its treasures, they made their way home to Nogrod.
 Aftermath and Repercussions
Before leaving, Melian had told Mablung to warn Beren about the evil deed of the Dwarves. Indeed, with the help of Green-elves and Ents he ambushed the Dwarves near Sarn Athrad. During the battle the host was destroyed and the treasure of Menegroth fell in Ascar. Save the Nauglamir which Beren brought to Lúthien.
