Galley tactics

Galley tactics were the dominant form of naval tactics used from antiquity to the late 16th century when sailing ships began to replace oared ships as the principal form of warships. Throughout antiquity and the Middle Ages until the 16th century, the weapons relied on were the ship itself, used as a battering ram or to sink the opponent with naval rams, the mêlée weapons of the crew, missile weapons such as bolts from heavy crossbows fixed on the bulwarks, bows and arrows, weights dropped from a yard or pole rigged out, and the various means of setting an enemy alight. The latter could be done by shooting arrows with burning tow or by Greek fire ejected through specially designed siphons.

All galley actions were fought at close quarters, where ramming and boarding were possible. But the use of the ram was only available for a vessel driven by oars. While fleets depended on the methods of battle at close quarters, two conditions were imposed on the warship: light structure, so that her crew could row her with effect, and a large crew to work her oars and fight in hand-to-hand combat. Sails were used by the virtually all types of galleys ancient and medieval in long-range strategic maneuvers, and to relieve the rowers from absolutely exhausting toil. Sails were lowered in action, however, and when the combatant had a secure port at hand, they were left ashore before battle.

Some medieval vessels were of considerable size, but these were the exception; they were awkward, and were rather transports than warships. Given a warship which is of moderate size and crowded with men, it follows that prolonged cruises, and blockade in the full sense of the word, were beyond the power of the sea commanders of antiquity and the Middle Ages. There were ships used for trade which with a favourable wind could rely on making six knots. But a war fleet could not provide the cover, or carry the water and food, needed to keep the crews efficient during a long cruise. So long as galleys were used, that is to say, till the middle of the 18th century, they were kept in port as much as possible, and a tent was rigged over the deck to house the rowers. The fleet was compelled to hug the shore in order to find supplies.
