Bert
3 Age.
T.A.2941. Bert, William, and Tom, caught Bilbo in Trollshaws when Bilbo encountered them upon his great journey to the Lonely Mountain. When Bilbo tried to steal William's purse from his pocket, the magical purse cried out and revealed him so Bilbo was caught. When the twelve Dwarves accompanying Bilbo tried to find and help Bilbo, they were caught too. Yet before the Trolls could decide what to do with their catch, Gandalf played a trick on them and they were trapped in the rising Sun and turned to stone.
