This dispatch shows that the Corsairs had speedily mastered the new manner of navigation, as might have been expected of a nation of sailors. They had long been acquainted with the great galleasse of Spain and Venice, a sort of compromise between the rowed galley and the sailing galleon; for it was too heavy to depend wholly on its oars (which by way of distinction were rowed under cover), and its great lateen sails were generally its motive power. The galleys themselves, moreover, had sails, though not square sails; and the seaman who can sail a ship on lateen sails soon learns the management of the square rig. The engravings on pp. 5, 11, 165, 197, and 227 sufficiently show the type of vessel that now again came into vogue, and which was known as a galleon, nave, polacca, tartana, barcone, caravel, caramuzel, &c., according to its size and country. The Turkish caramuzel or tartan, says Furttenbach, stands high out of the water, is strong and swift, and mounts eighteen or twenty guns and as many as sixty well-armed pirates. It is a dangerous vessel to attack. From its commanding height its guns can pour down so furious a fire upon a Christian craft that the only alternative to surrender is positive extirpation. If the enemy tries to sneak out of range below the level of fire, the Turks drop grenades from the upper decks and set the ship on fire, and even if the Christians succeeded in boarding, they find themselves in a trap: for though the ship's waist is indeed cleared of the enemy, the hurricane decks at poop and prow command the boarding party, and through loopholes in the bulwarks--as good a cover as a trench--a hail of grape pours from the guns, and seizing their opportunity the Turks rush furiously through the doors and take their opponents simultaneously in face and rear; and then comes a busy time for scimitar and pike. Or, when you are alongside, if you see the caramuzel's mainsail being furled, and something moving in the iron cage on the _gabia_ or maintop, know that a petard will soon be dropped in your midst from the main peak, and probably a heavy stone or bomb from the opposite end of the long lateen yard, where it serves the double purpose of missile and counterpoise. Now is the time to keep your distance, unless you would have a hole in your ship's bottom. The Corsairs, indeed, are very wily in attack and defence, acquainted with many sorts of projectiles,--even submarine torpedoes, which a diver will attach to the enemy's keel,--and they know how to serve their stern chasers with amazing accuracy and rapidity.[67]
