A. First Truly Pirate Ship.
B. Legendary Figure of His Time С Fearsome Reputation
D. Love and Glory
E. Remarkable Finds
F. Pirates of the Caribbean
1. The recent discovery of the wreck of an old ship on the ocean floor near the coast of North Carolina has revived interest in the colorful character of the ship's last captain. The ship is the Queen Anne's Revenge, which sank in 1718. Her captain was called Blackbeard, whose real name was Edward Teach. He had been a sailor on British ships in the Caribbean during Queen Anne's War (1702-1713). These ships often attacked French and Spanish ships in the region and kept a percentage of whatever they captured from these enemies of the queen.
2. All this changed in 1713 when the European powers declared peace and the war ended. Teach and other sailors had to choose between returning to unemployment in Britain or continuing to do what they knew best, only as pirates. They started as small bands in small boats, attacking and robbing merchant ships. Soon they took control over larger ships in and near the Caribbean.
3. When they captured a large French ship, which they renamed Queen Anne's Revenge, Blackbeard and his crew finally had a true pirate ship, 80 feet long, with three masts and more than three dozen cannons. Blackbeard soon learned that a fearsome reputation, a pirate flag and some warning shots from his cannons were all that he needed to stop most ships without a fight.
4. In those days, Blackbeard is described as a 'demon from heir, with a huge black beard and who carried several guns and swords in belts slung across both shoulders.
5. Blackbeard's reign of terror lasted until 1718 when he was killed in a sea battle with two British ships which had been sent to put an end to piracy in the region. After his death, Blackbeard became a romantic figure and stories about his daring adventures and tales of secretly buried treasure helped to create the popular image of pirates we still have today.-
