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 melee 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.
In galley warfare, a secure basis on shore to store provisions and rest the crews was highly beneficial. Therefore the wider operations were slowly made. Therefore too, when the enemy was to be waited for, or a port watched, some point on shore was secured and the ships were drawn up. It was by holding such a point that the Corinthian allies of the Syracusans were able to pin in the Athenians. The Romans watched Lilybeum in the same way, and Hannibal the Rhodian could run the blockade before they were launched and ready to stop him. The Norsemen hauled their ships on shore, stockaded them and marched inland. Roger of Lauria, in 1285, waited at the Formigues with his galleys on the beach till the French were seen to be coming past him. Edward III. In AD 1350, stayed at Winchelsea till the Spaniards were sighted. The allies at Lepanto remained at anchor near Dragonera till the last moment.
As a defense against boarding, the ships of a weaker fleet were sometimes tied side to one another, in the Middle Ages, and a barrier made with oars and spars. But this defensive arrangement, which was adopted by Olaf Tryggvason of Norway at Swolder (AD 1000), and by the French at Sluys (AD 1340), could be turned by an enemy who attacked on the flank. To meet the shock of ramming and to ram, medieval ships were sometimes "bearded", i.e. fortified with iron bands across the bows.
From the earliest times of naval warfare boarding was the only means of deciding a naval engagement, but little to nothing is known about the tactics involved. In the first recorded naval battle in history, the battle of the Delta, the forces of Egyptian Pharaoh Ramesses III won a decisive victory over a force made up of the enigmatic group known as the Sea Peoples. As shown in commemorative reliefs of the battle, Egyptian archers on ships and the nearby shores of the Nile rain down arrows on the enemy ships. At the same time Egyptian galleys engage in boarding action and capsize the ships of the Sea Peoples with ropes attached to grappling hooks thrown into the rigging.
Introduction of the ram
Around the 8th century BC, ramming began to be employed as war galleys were equipped with heavy bronze rams. Records of the Persian Wars in the early 5th century BC by the Ancient historian Herodotus (c. 484-425 BC) show that by this time ramming tactics had evolved among the Greeks. The formations could either be in columns in line ahead, one ship following the next, or in a line abreast, with the ships side by side, depending on the tactical situation and the surrounding geography. There were two primary methods for attack: by breaking through the enemy formation (diekplous) or by outflanking it (periplous). The diekplous involved a concentrated charge in line ahead so as to break a hole in the enemy line, allowing galleys to break through and then wheel to attack the enemy line from behind. The periplous involved outflanking or encircling the enemy so as to attack them in the vulnerable rear or side by line abreast. If one side knew that it had slower ships, a common tactic was to form a circle with the bows pointing outwards, thereby avoiding being outflanked. At a given signal, the circle could then fan out in all directions, trying to pick off individual enemy ships. To counter this formation, the attacking side would rapidly circle, feigning attacks in order to find gaps in the formation to exploit.
Ramming itself was done by smashing into the rear or side of an enemy ship, punching a hole in the planking. This did not actually sink an ancient galley unless it was heavily laden with cargo and stores. With a normal load, it was buoyant enough to float even with a breached hull. It could also maneuver for some time as long as the oarsmen were not incapacitated, but would gradually lose mobility and become unstable as it flooded. The winning side would then attempt to tow away the swamped hulks as prizes. Breaking the enemy's oars was another way of rendering ships immobile, rendering them into easier targets. If ramming was not possible or successful, the on-board complement of soldiers would attempt to board and capture the enemy vessel by attaching to it with grappling irons. Accompanied by missile fire, either with bow and arrow or javelins. Trying to set the enemy ship on fire by hurling incendiary missiles or by pouring the content of fire pots attached to long handles is thought to have been used, especially since smoke below decks would easily disable rowers.
The speed necessary for a successful impact depended on the angle of attack; the greater the angle, the lesser the speed required. At 60 degrees, 4 knots was enough to penetrate the hull, but this increased to 8 knots at 30 degrees. If the target for some reason was in motion towards the attacker, less speed was required, especially if the hit came amidships. War galleys gradually began to develop heavier hulls with reinforcing beams at the waterline, where a ram would most likely hit. There are records of a counter-tactic to this used by Rhodian ship commanders where they would angle down their bows to hit the enemy below the reinforced waterline belt. Besides ramming, breaking enemy oars was also a way to impede mobility and make it easier to drive home a successful ramming attack.
Despite the attempts to counter increasingly heavy ships, ramming tactics were superseded in the last centuries BC by the Macedonians and Romans who were primarily land-based powers. Hand-to-hand fighting with large complements of heavy infantry supported by ship-borne catapults dominated the fighting style during the Roman era, a move that was accompanied by the conversion to heavier ships with larger rowing complements and more men per oar. Though effectively lowering mobility, it meant that less skill was required from individual oarsmen. Fleets thereby became less dependent on rowers with a lifetime of experience at the oar.
In fact success in ramming depended so much on a combination of skill and good fortune that it played a somewhat subordinate part in most ancient sea fights. The Romans baffled the ramming tactics of the Carthaginians by the invention of the corva, or crow, a plank with a spike for hooking onto enemy ships which grappled the prow of the rammer, and provided a gangway for boarders. It's not certain whether this weapon destabilized ships and led to whole fleets being lost in storms. The Romans did continue their boarding tactics in the naval battles of the Punic Wars, but are also reported as ramming the Carthiginian vessels after the abandonment of the corvus. An older and alternative way for boarding was the use of grappling hooks and planks, also a more flexible system than the corvus. Agrippa introduced a weapon with a function similar to the corvus, the harpax.
By late antiquity, in the 1st centuries AD, ramming tactics had completely disappeared along with the knowledge of the original trireme and its high speed and mobility. The ram was replaced by a long spur in the bow that was designed to break oars and to act as a boarding platform for storming enemy ships. The only remaining examples of ramming tactics was passing references to attempts to collide with ships in order to roll it over on its side.
With the collapse of the unified Roman empire came the revival of large fleet actions. The Byzantine navy, the largest Mediterranean war fleet throughout most of the early Middle Ages, employed crescent formations with the flagship in the center and the heavier ships at the horns of the formation, in order to turn the enemy's flanks. Similar tactics are believed to have been employed by the Arab fleets they frequently fought from the 7th century onwards. The Byzantines were the first to employ Greek fire, a highly effective incendiary liquid, as a naval weapon. It could be fired through a metal tube, or siphon mounted in the bows, similar to a modern flame thrower. The properties of Greek fire were close to that of napalm and was a key to several major Byzantine victories. By 835, the weapon had spread to the Arabs, who equipped harraqas, "fireships", with it.
Once the fleets were close enough, exchanges of missiles began, ranging from combustible projectiles to arrows, caltrops and javelins. The aim was not to sink ships, but to deplete the ranks of the enemy crews before the boarding commenced, which decided the outcome. Once the enemy strength was judged to have been reduced sufficiently, the fleets closed in, the ships grappled each other, and the marines and upper bank oarsmen boarded the enemy vessel and engaged in hand-to-hand combat. On Byzantine galleys, the brunt of the fighting was done by heavily armed and armored troops called hoplites or kataphraktoi. These would attempt to stab the rowers through the oarports to reduce mobility, and then join the melée. If boarding was not deemed advantegous, the enemy ship could be pushed away with poles.
Later medieval navies continued to use similar tactics, with the line abreast (i.e. side by side) formation as standard. As galleys were intended to be fought from the bows, and were at their weakest along the sides, especially in the middle. The crescent formation employed by the Byzantines continued to be used throughout the Middle Ages. It would allow the wings of the fleet to crash their bows straight into the sides of the enemy ships at the edge of the formation.
Early modern period
In large-scale galley engagements tactics remained essentially the same until the end of the 16th century. The same basic crescent formation in line abreast that was employed at the battle of Lepanto in 1571 was used by the Byzantine fleet almost a millennium earlier. The practical maximum size of the front ranks of a galley formation was about 65 ships in the center with another 53-54 ships on the left and right wings. Cannons and small firearms were introduced around the 14th century, but did not have any immediate effect on tactics. If anything, the forward offensive power of galleys was accentuated by naval artillery.
Artillery on early gun galleys was not used as a long-range standoff weapon against other gun-armed galleys. The maximum distance at which contemporary cannons were effective, c. 500 m (1600 ft), could be covered by a galley in about two minutes, much faster than the reload time of any artillery piece. Gun crews would therefore hold their fire until the last possible moment, somewhat similar to infantry tactics in the pre-industrial era of short range firearms. The bow guns would often be loaded with scatter shot and other anti-personnel ammunition. The effect of an assault with a gun-armed galley could often be dramatic, as exemplified by an account from 1528 where a galley of Genoese commander Antonio Doria. On board the ship of Sicilian Don Hugo de Moncada he witnessed how a single volley from a basilisk, two demi-cannons and four smaller guns killed 40 men.
The estimated average speed of Renaissance-era galleys was fairly low, only 3 to 4 knots, and a mere 2 knots when holding formation. Short bursts of up to 7 knots were possible for about 20 minutes, but only at the risk of exhausting rowers. This made galley actions relatively slow affairs, especially when they involved fleets of 100 vessels or more. The weak points of a galley remained the sides and especially the rear, the command center, and were the preferred targets of any attacker. Unless one side managed to outmaneuver the other, battle would be met with ships crashing into each other head on. Once the fighting began with galleys locking on to one another bow to bow, the fighting would be over the front line ships. Unless one was completely taken over by a boarding party, fresh troops could be fed into the fight from reserve vessels in the rear. In a defensive position with a secure shoreline, galleys could be beached stern first with its guns pointing out to sea. This made for a very strong defensive position, allowed rowers and sailors to escape to safety on land, leaving only soldiers and fighting men to defend against an assault.
