Blackbeard's lawless career lasted only a few years, but his fearsome reputation has long outlived him. Thought to have been a native of England, he was using the name Edward Teach (or Thatch) when he began his pirating sometime after 1713 as a crewman aboard a Jamaican sloop commanded by the pirate Benjamin Hornigold. In 1716 Hornigold appointed Teach to command a captured vessel. By mid-1717 the two, sailing in concert, were among the most feared pirates of their day. In November 1717, in the eastern Caribbean, Hornigold and Teach took a 26-gun, richly laden French "guineyman" called the Concorde (research indicated she had originally been built in Great Britain). Hornigold subsequently decided to accept the British Crown's recent offer of a general amnesty and retire as a pirate. Teach rejected a pardon, decided to make the Concorde his flagship, increased her armament to 40 guns, and renamed her Queen Anne's Revenge or (QAR).
