About Thomas Blood:
Colonel Thomas Blood was an Anglo-Irish officer and self-styled colonel best known for his attempt to steal the Crown Jewels of England from the Tower of London in 1671. Described in an American source as a "noted bravo and desperado," he was known for his attempt to kidnap and, later, to kill, his enemy, the Duke of Ormonde. He had switched allegiances from Royalist to Roundhead during the Wars of the Three Kingdoms, and despite his subsequent notoriety received a Royal free pardon and found favour at the court of King Charles II.
