Glaurung's attack on Beleriand

Glaurung's attack on the Beleriand was a lone attack on the Beleriand by the young "Father of Dragons" Glaurung.

The attack failed.

Background
During the Siege of Angband, the Ñoldor successfully laid siege to Angband building many castles fortifications that ever watched the Gates of Angband, and no doubt kept legions of mounted and unmounted sentinels on the plain of Ard-galen. Fenced in, Morgoth choose not to attack in force as before and took council with himself on how he might defeat his enemy in other ways. During these long years, Morgoth began the breeding of the Dragons and the most prominent and well-known in later years was Glaurung, the first of the deadly Fire-drakes.

The Attack
Glaurung, still young and only half-grown felt strong enough to strike. Without orders from his master, he came forth suddenly from the Gates of Angband. At first the Ñoldor were terrified at this new menacing foe and fled before him southward, allowing him defile Ard-galen with his hot blasts of destroying flames, but the Ñoldor were not defeated and regrouped in around Dorthonion and Ered Wethrin under Fingon. They rode up to face him hitting him with volley after volley of arrows and soon he was surrounded. At point-blank range, Fingon and his Ñoldor riders continued their barrage of arrows and Glaurung unable to endure these weapons due to his weak armor was defeated. Wounded, Glaurung was able to escape back to Angband safely.

Aftermath
While the Ñoldor celebrated their victory, Glaurung was scolded by Morgoth for revealing himself too soon and without full strength. Afterwards, there was peace for two-hundred some years with the Ñoldor creating great watchtowers behind which the fruits of peace flourished.
