Burned Dwarves

The War of the Dwarves and Orcs reached its end in the Battle of Azanulbizar, in which Thráin II led the armies of the Dwarves against Azog and his horde of Orcs. The two forces met in the valley of Azanulbizar, the Dimrill Dale, beneath the East-gate of Moria. The battle was ferocious, and though the Dwarves were victorious, their losses were great.

By custom, the Dwarves would lay their dead in tombs of stone, but so many were slain in the battle that their people broke tradition and instead burned their bodies on flaming pyres. From that day the phrase 'burned Dwarf' became a title of honour, used of those who had fallen avenging Thrór in the Battle of Azanulbizar.
