On May 9, 1671 Thomas Blood, disguised as a clergyman, attempted to steal the Crown Jewels from the Tower. He was immediately caught because he was too drunk to run with the loot. He later was condemned to death for his actions but was mysteriously pardoned, exiled and given a pension by King Charles II.
