Azaghal vs Glaurung

From "Silmarillion", J.J. Tolkien, page 229, Azaghal lord of the dwarves of Belegost, v/s Glaurung the ruin of Angband, father of dragons.

Of the fifth battle Nirnaeth Arnoediad:

"Last of all the eastern force to stand firm were the Dwarves of Belegost, and thus they won renown. For the Naughrim withstood fire more hardily than either Elves or Men, and it was their custom moreover to wear great masks in battle hideous to look upon; and those stood them in good stead against the dragons. And but for them Glaurung and his brood would have witered all that was left of the Noldor. But the naugrim made a circle about him when he assailed them, and even his mighty armour was not full proof against the blows of their great axes; and when in his rage Glaurung turned and struck down Azagal, Lord of Belegost, and crawled over him, with his last stroke Azaghal drove a knife into his belly, and so wounded him that he fled the field, and the beasts of Angband in dismay followed after him. Then the dwarves raised up the body of Azagal and bore it away; and with slow steps they walked behind singing a dirge in deep voices, as it were a funeral pomp in their country, and gave no heed more to their foes; and none dared to stay them.
