Overview


Early history

Since ancient times, war at sea had been fought much as on land: with melee weapons and bows and arrows, but on floating wooden platforms rather than battlefields. Though the introduction of guns was a significant change, it only slowly changed the dynamics of ship-to-ship combat. The first guns on ships were small wrought-iron pieces mounted on the open decks and in the

s, often requiring only one or two men to handle them. They were designed to injure, kill or simply stun, shock and frighten the enemy prior to boarding. As guns were made more durable to withstand stronger gunpowder charges, they increased their potential to inflict critical damage to the vessel rather than just its crew. Since these guns were much heavier than the earlier anti-personnel weapons, they had to be placed lower in the ships, and fire from gunports, to avoid ships becoming unstable. In Northern Europe the technique of building ships with

planking made it difficult to cut ports in the hull; clinker-built (or clench-built) ships had much of their structural strength in the outer hull. The solution was the gradual adoption of carvel-built ships that relied on an internal skeleton structure to bear the weight of the ship.

sails made ships nimbler and easier to manoeuvre. Gunports cut in the hull of ships had been introduced as early as 1501. According to tradition the inventor was a Breton shipwright called Descharges, but it is just as likely to have been a gradual adaptation of loading ports in the stern of merchant vessels that had already been in use for centuries. Initially, the gunports were used to mount heavy so-called stern chasers pointing aft, but soon gunports migrated to the sides of ships. This made possible for the first time in history coordinated volleys from all the guns on one side of a ship, broadsides, at least in theory. Guns in the 16th century were considered to be in fixed positions and were intended to be fired independently rather than in concerted volleys. It was not until the 1590s that the word "broadside" in English was commonly used to refer to gunfire from the side of a ship rather than the ship's side itself. Naval tactics throughout the 16th century and well into the 17th century were focused on countering the oar-powered

s that were armed with forward-facing heavy guns in the bow, which were aimed by turning the entire ship against its target. Though far less seaworthy than sailing vessels and highly vulnerable to boarding by ships that rode higher in the water, the galleys were a serious threat due to their ability to aim accurate heavy gunfire low in the hulls of larger sailing ships and to escape solely sail-powered opponents by rowing into the wind.


Initial tactics

The
line of battle The line of battle is a tactic in naval warfare in which a fleet of ships forms a line end to end. The first example of its use as a tactic is disputed—it has been variously claimed for dates ranging from 1502 to 1652. Line-of-battle tacti ...
tactic that allowed efficient use of broadside fire was not put into general use until the mid 17th century, as was described by English General at Sea Robert Blake in his ''Laws of War and Ordinances of the Sea''. The previous solution was to make sailing ships fire backwards from the stern, as a defensive measure, or forward from the bow, as an offensive measure. The latter was only partially achieved either by canting (angling) the side guns towards the bow or stern as far as the ship's structure would allow, or by placing guns on the sterncastle and fire them in an arc on either side of the forecastle. Both solutions were problematic since they created a blind spot dead ahead and made it especially difficult to hit low-lying targets, like galleys. The method that was deemed most effective by contemporaries was to simply counter the threat of galleys with other galleys. Despite the technical innovations, naval

meant that all guns allowed for considerable "windage", meaning that bore diameters were about 10 percent larger than their ammunition. Combined with inefficient gunpowder and the difficulties inherent in firing accurately from moving platforms meant that naval tactics for sailing ships throughout the 16th century remained focused on boarding as a means of decisive victory. Naval tactics in the

. Raking another ship by firing the length of a ship from either the bow or stern caused tremendous damage, because a single shot would fly down the length of the decks, while the ship being raked could not return fire with its broadsides. Moreover, the externally-mounted rudder was at the stern, and any hit there would render the ship essentially unsteerable and without the ability to maneuver, even with masts and sails intact. * The third constraint was the difficulty of communicating at sea. Written communication was almost impossible in a moving fleet, while hailing was extremely difficult above the noise of wind and weather. Admirals were forced to rely on a pre-arranged set of signal flags hoisted aboard the admiral's

. This meant that what had earlier been the hold of a ship that could be used either as a merchant ship or warship was now full with cannon and ammunition. Hence ships became specialised as warships, which would lead to a standing fleet instead of one based on placing temporary contracts. The man-of-war eventually rendered the galley obsolete except for operations close to shore in calm weather. With the development of the sailing man-of-war, and the beginning of the great sailing fleets capable of keeping at sea for long periods together, came the need for a new adaptation of old principles of naval tactics. A ship that depended on the wind for its motive power could not hope to ram. A sailing vessel could not ram unless it was running before a good breeze. In a light wind, the charge would be ineffective, and it could not be made at all from

to the commander of a fleet dispatched to the Indian Ocean suggests its use predated the written instructions. Portuguese fleets overseas deployed in line ahead, firing one broadside and then putting about in order to return and discharge the other, resolving battles by gunnery alone. In a treatise of 1555, ''The Art of War at Sea'', Portuguese theorist on naval warfare and shipbuilding, Fernão de Oliveira, recognized that at sea, the Portuguese "fight at a distance, as if from walls and fortresses...". He recommended the single line ahead as the ideal combat formation. An early line of battle tactic had been used by the Fourth Portuguese India Armada in the Battle of Calicut, under

Importance of the weather gage

Holding the weather, or windward, gage conferred several important tactical advantages. The admiral holding the

held the tactical initiative, able to accept battle by bearing down on his opponent or to refuse it by remaining upwind. The fleet with the lee gage could avoid battle by withdrawing to leeward, but could not force action. Even retreating downwind could be difficult once two fleets were at close quarters because the ships risked being raked as they turned downwind. A second disadvantage of the leeward gage was that in anything more than a light wind, a sailing ship that is sailing close hauled (or beating) will heel to leeward under the pressure of the wind on its sails. The ships of a fleet on the leeward gage heel away from their opponents, exposing part of their bottoms to shot. If a ship is penetrated in an area of the hull that is normally under water, she is then in danger of taking on water or even sinking when on the other tack. This is known as "hulled between wind and water". Finally, smoke from the gunfire of the ships to windward would blow down on the fleet on the leeward gage. It was common for battles to involve days of manoeuvring as one admiral strove to take the weather gage from his opponent in order to force him to action, as at the battles of

(1778), St Lucia Channel (1780) and the First of June (1794). Only in heavy weather could the windward gage become a disadvantage, because the lower gun ports on the leeward side of a ship would be awash, preventing her from opening her lower-deck ports to use the guns – or risking being swamped if she did. So, in strong winds, a ship attacking from windward would not be able to bring her heavy lower-deck guns into action, while the enemy ship to leeward would have no such problem as the guns on her windward side would be raised by the heel. For this reason, Admiral Rodney ordered his ships to attack the Spanish from leeward in the stormy weather at the Battle of Cape St. Vincent in 1780.

, sailing tactics were developed by the treatises of the French tacticians Paul Hoste, Bigot de Morogues and Bourde de Villehuet, which developed the traditional code of practice and were all translated into other languages. During the 18th century, French governments developed the strategic doctrine of focusing on the mission, rather than fighting for command of the sea. The French government was often reluctant to take tactical risks to achieve its strategic objectives. The navy was hampered by the timidity of its orders. French fleets and squadrons typically sought to avoid battle rather than risk a contest with a British force, as De Ternay did in June 1780 on meeting a smaller British squadron under Cornwallis off

. This strategy had important tactical ramifications. French ships tended to fire at the rigging of their opponents to disable them and allow the French ships to escape and continue with their mission. French ships typically fired their broadsides on the upward roll of the ship, disabling their opponents but doing little damage to the enemy ships or their crews. This was compounded by the French tendency to fight from the leeward gage, causing the guns to point high as the ships heeled with the wind. British and Dutch ships, by contrast, tended to use the opposite tactic of firing on the downward roll into the enemy hulls, causing a storm of flying splinters that killed and maimed the enemy gun crews. This difference in tactics goes some way to explaining the difference in casualty figures between British and French crews, with French fleets tending to suffer not only more casualties but also a higher proportion of killed than wounded.


Tactical stagnation in the mid-18th century

When the conflict came to be between the British and the French in the 18th century, battles between equal or approximately equal forces became largely inconclusive. The French, who had fewer ships than the British throughout the century, were anxious to fight at the least possible cost, lest their fleet should be worn out by severe action, leaving Britain with an unreachable numerical superiority. Therefore, they preferred to engage to leeward, a position which left them free to retreat before the wind. They allowed the British fleet to get to windward, and when it was parallel with them and bore up before the wind to attack, they moved onwards. The attacking fleet had then to advance, not directly before the wind with its ships moving along lines perpendicular to the line attacked, but in slanting or curving lines. The assailants would be thrown into "a bow and quarter line" – with the bow of the second level with the after part of the first and so on from end to end. In the case of a number of ships of various powers of sailing, it was a difficult formation to maintain. The result was often that the ships of the attacking line which were steering to attack the enemy's centre came into action first and were liable to be crippled in the rigging. If the same formation was to be maintained, the others were now limited to the speed of the injured vessels, and the enemy to leeward slipped away. At all times a fleet advancing from windward was liable to injury in spars, even if the leeward fleet did not deliberately aim at them. The leeward ships would be leaning away from the wind, and their shot would always have a tendency to fly high. So long as the assailant remained to windward, the ships to leeward could always slip off. The wars of the 18th century produced a series of tactically indecisive naval battles between evenly matched fleets in line ahead, such as

. It was clear that the only way to produce decisive results was to concentrate the attack on part of the enemy's line, preferably the rear since the centre would have to turn to its support. The great French admiral Suffren condemned naval tactics as being little better than so many excuses for avoiding a real fight. He endeavoured to find a better method, by concentrating superior forces on parts of his opponent's line in some of his actions with the British fleet in the East Indies in 1782 and 1783, such as the

where Suffren tried to double the rear of the British line. But his orders were ill obeyed, his opponent Sir Edward Hughes was competent, and the quality of his fleet was not superior to the British. Similarly, the British admiral Rodney, in the Battle of Martinique in the West Indies in 1780, tried to concentrate a superior force on part of his enemy's line by throwing a greater number of British ships on the rear of the French line. But his directions were misunderstood and not properly executed. Moreover, he did not then go beyond trying to place a larger number of ships in action to windward against a smaller number to leeward by arranging them at a lesser distance than two-cables length. An enemy who took the simple and obvious course of closing his line could baffle the attack, and while the retreat to leeward remained open could still slip away. Like Suffren, Rodney was a great tactician, but a difficult man to work with who failed to explain his intentions to his subordinates. At the

on 12 April 1782, Rodney was induced, by a change in the wind and the resulting disorder in the French line, to break his own line and pass through the enemy line. The effect was decisive. The guns of the British ships were concentrated on a handful of French ships as the British broke through the French line in three places, and the tactical cohesion of the French fleet was destroyed. By the end of the battle, Rodney had taken the French

He began developing a series of speculations and calculations which he initially published in pamphlets, distributing them among naval officers, and published in book form as ''An Essay on Naval Tactics'' in 1790, 1797 and 1804. The hypothesis which governed all of Clerk's demonstrations was that as the British navy was superior in gunnery and seamanship to their enemy, it was in their interest to produce a mêlée. He advanced various ingenious suggestions for concentrating superior forces on parts of the enemy's line – by preference on the rear, since the centre must lose time in turning to its support.

, a Scottish ironworks, in 1778. Because of irregularities in the size of cannonballs and the difficulty of boring out gun barrels, there was usually a considerable gap between the ball and the bore – often as much as a quarter of an inch – with a consequent loss of efficiency. This gap was known as the "windage". The manufacturing practices introduced by the Carron Company reduced the windage considerably, enabling the ball to be fired with less powder and hence a smaller and lighter gun. The carronade was half the weight of an equivalent long gun, but could throw a heavy ball over a limited distance. The light weight of the carronade meant that the guns could be added to the forecastle and quarterdeck of frigates and ships of the line, increasing firepower without affecting the ship's sailing qualities. It became known as the “smasher” and gave ships armed with carronades a great advantage at short range. * The

giving an almost instantaneous burn time compared with earlier methods of detonation. * A wider field of fire: by the simple expedient of attaching the gun ropes at a greater distance from the gunports, the British gunnery innovator Captain Sir Charles Douglas increased the range through which each cannon could be traversed, increasing the ship's field of fire. The new system was first tested at the Battle of the Saintes, in 1782, where the ''Duke'', ''Formidable'' and ''Arrogant'', and perhaps other British ships, had adopted Douglas's new system. * Copper sheathing: after many trials,

. Copper sheathing delayed the growth of weeds on the hull, improving the sailing performance of ships that had been long out of dock. This had significant strategic as well as tactical implications. Up to 1780, the British, who kept their ships at sea for longer periods, had almost always found that the clean French ships were faster and could therefore avoid battle if they wished. The introduction of copper sheathing meant that ships that had spent months on blockade were not necessarily at an immediate speed disadvantage to enemy ships coming freshly out of port.

escort gave British captains plenty of opportunities to train their crews. British gun crews achieved a higher rate of fire than French or Spanish gun crews, contributing to the much higher casualties suffered by ships from those fleets. The better seamanship, faster gunnery and higher morale of British crews was a decisive advantage. The leading British admirals like Howe devoted their efforts to how to break the enemy's line in order to bring on the kind of pell mell battle that would bring decisive results. At the Battle of the First of June in 1794, Lord Howe ordered his fleet to steer through the enemy, and then engage the French ships from the ''leeward'', so as to cut off their usual retreat. This had the effect of bringing his fleet into a melee in which the individual superiority of his ships would have free play. Throughout the wars, which lasted, with a brief interval of peace, from 1793 to 1815, British admirals like Jervis,

as the British ships passed through the Franco-Spanish line. It has been argued the tactics of these British admirals were too risky, and would have proved disastrous if tried against more skillful opponents. But it has been remarked that, "this is one of those criticisms which are of value only against those who think that there can be a magic efficacy in any particular attack, which makes its success infallible." That the tactics of British admirals of the wars of 1793–1815 had in themselves no such advantage, was demonstrated at the Battle of Lissa in 1811. The tactics were justified because the reliance of admirals on the quality of their fleets was well based. A vessel, while bearing down on an enemy's line, could not be exposed to the fire of three enemies at once, when at a distance less than 950 yards, because the guns could not be trained to converge on a nearer point. The whole range of effective fire was only a thousand yards or a little over. The chance that a ship would be dismasted and stopped before reaching the enemy's line was small.


Fighting at anchor

Towards the end of the period of sailing navies, a number of fights took place between defending fleets or squadron anchored close to the shore or in harbours, and attacking fleets forced to sail to within range while under fire. Such battles tended to be decisive, as a wind which was fair to allow the attackers to enter a harbour or anchorage would let neither side out again. As it would normally be more profitable for the attackers to blockade the enemy until they were forced to sortie to accept battle in open water, such attacks were usually forced by lack of time, e.g. by shortage of supplies, the threatened onset of bad weather or the need to coordinate operations with an army on land. The defenders could expect to enjoy several advantages. As they would not need to manoeuvre under sail, most of the ships' crews could man the guns. If properly prepared, the ships would have "springs"; extra cables bound to the anchor cables, which they could haul in or let out to veer the ship to bring its guns to bear over a wide arc. If close to a naval establishment (such as at the Battle of Copenhagen), they could rely on boats from the shore to bring extra ammunition or replacements for casualties and if in range the defending ships could be aided by coastal gun batteries. The worst British naval reverse of the Napoleonic Wars occurred during an attack on a protected anchorage at the

Rules and incentives

In a paper in ''Explorations in Economic History'', Douglas Allen argues the long period of British success fighting under sail depended on organizational rules surrounding officers and paying officers through prizes, which were designed to encourage officers to be at sea, to drill their crews to fight, and to engage the enemy. As a consequence, the Royal Navy did not depend on superior technology, geography, or luck. The rules were discarded with the introduction of steam which allowed for direct monitoring of captains and admirals. In contrast, Allen argues the French incentives did not encourage fighting and led to a Navy better trained in sailing.
