The dwarves are happy to be back in their old home, and to have their old treasures back. Thorin sends a message to the dwarves of his people, and tells them to come. But soon the people from Laketown and the Mirkwood-Elves arrive. Both peoples want a part of the treasure, but the dwarves do not want to give them anything. The humans and elves start a siege of the Lonely Mountain. After a while the other dwarves of Thorin's people come: Dáin II Ironfoot and an army of dwarves.
