The Battle of Moria == The Battle of Moria happend after the dragon Smaug took over the Lonely Mountain they went to the last salvation of dwarves but the Pale Orc (Azog the Defiler) got there first they fought. Azog kiilled Thror and said to kill all of the line of Durin , but Thorin cut his hand off. Thrain went crazy and fled but they ended victorius.
There was no song or party after that battle as you know the songs of the dwarves are the most meaninful of all. They thought Azog the Defiler was dead but they should have known better as to think that.
