In The Hobbit, the dwarves names were Fili, Kili, Oin, Gloin,  Thorin Oakenshield, Dwalin, Balin, Bifur, Bofur, Bombur, Dori,  Nori, and Ori, so there were 13.
The trio of Trolls captured Bilbo who, almost revealing himself as a burglar, identified himself as a burâa hobbit, which they mistook for a burrahobbit. Eventually all of the dwarves in Thorin's company came looking for Bilbo, and were waylaid by the trolls and put into sacks. The trolls then discussed ways to kill and eat the dwarves, until Gandalf came and mimicked the Trolls' voices, starting a fight amongst them.
