Between the two decks, in the ship's waist, is the propelling power: fifty-four benches or banks, twenty-seven a side, support each four or five slaves, whose whole business in life is to tug at the fifty-four oars. This flagship is a Christian vessel, so the rowers are either Turkish and Moorish captives, or Christian convicts. If it were a Corsair, the rowers would all be Christian prisoners. In earlier days the galleys were rowed by freemen, and so late as 1500 the Moors of Algiers pulled their own brigantines to the attack of Spanish villages, but their boats were light, and a single man could pull the oar. Two or three were needed for a galleot, and as many sometimes as six for each oar of a large galley. It was impossible to induce freemen to toil at the oar, sweating close together, for hour after hour--not sitting, but leaping on the bench, in order to throw their whole weight on the oar. "Think of six men chained to a bench, naked as when they were born, one foot on the stretcher, the other on the bench in front, holding an immensely heavy oar [fifteen feet long], bending forwards to the stern with arms at full reach to clear the backs of the rowers in front, who bend likewise; and then having got forward, shoving up the oar's end to let the blade catch the water, then throwing their bodies back on to the groaning bench. A galley oar sometimes pulls thus for ten, twelve, or even twenty hours without a moment's rest. The boatswain, or other sailor, in such a stress, puts a piece of bread steeped in wine in the wretched rower's mouth to stop fainting, and then the captain shouts the order to redouble the lash. If a slave falls exhausted upon his oar (which often chances) he is flogged till he is taken for dead, and then pitched unceremoniously into the sea."[57] "Those who have not seen a galley at sea, especially in chasing or being chased, cannot well conceive the shock such a spectacle must give to a heart capable of the least tincture of commiseration. To behold ranks and files of half-naked, half-starved, half-tanned meagre wretches, chained to a plank, from whence they remove not for months together (commonly half a year), urged on, even beyond human strength, with cruel and repeated blows on their bare flesh, to an incessant continuation of the most violent of all exercises; and this for whole days and nights successively, which often happens in a furious chase, when one party, like vultures, is hurried on almost as eagerly after their prey, as is the weaker party hurried away in hopes of preserving life and liberty."[58]
