Sack of Erebor

The final blow to the Dwarfs after the War of Dwarves and Dragons, was the coming of Smaug. Smaug had grown into a mighty dragon--and he made battle against the Men of Dale and the Dwarfs of Erebor. Smaug was undeterred and made Erebor his. Smaug killed Girion and destroyed Dale along with hundreds of Dwarves.
