Battle in Erebor

The Battle in Erebor took place in TA 2941 between the dragon Smaug and the Dwarfish company led by Thorin II Oakenshield, along with Bilbo Baggins, in an attempt to destroy the dragon once and for all and retake the Kingdom of Erebor. Bilbo had already done some exploration of the old hallways using the Back Door and had stolen the Arkenstone from the treasure. By this deed and by Bilbo's bold speech Smaug's anger was kindled. The battle, which lasted for several minutes, ended with Smaug taking off to Esgaroth to destroy it.
