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 Malaga (1704), Rügen Island (1715), Toulon (1744), Minorca (1756), Negapatam (1758), Cuddalore (1758), Pondicherry (1759), Ushant (1778), Dogger Bank (1781), the Chesapeake (1781), Hogland (1788) and Öland (1789). Although a few of these battles had important strategic consequences, like the Chesapeake which the British needed to win, all were tactically indecisive. Many admirals began to believe that a contest between two equally matched fleets could not produce a decisive result. The tactically decisive actions of the 18th century were all chase actions, where one fleet was clearly superior to the other, such as the two battles of Finisterre (1747), and those at Lagos (1759), Quiberon Bay (1759) and Cape St. Vincent (1780).

British naval innovation was retarded by an unseemly dispute between two Admirals in the aftermath of the Battle of Toulon. The British fleet under Admiral Thomas Mathews had been unable to draw level with the French fleet but Mathews nevertheless ordered an attack, intending all the British ships to attack the French rear. He had no signals by which he could communicate his intentions, and the rear squadron under Vice Admiral Richard Lestock, his rival and second-in-command, obtusely remained at the prescribed intervals in line ahead, far to the rear of the action. A subsequent series of courts-martial, in which political influence was brought to bear by Lestock's friends in Parliament, punished Mathews and those captains who had supported him in the battle, and vindicated Lestock. In several future actions, Admirals who were tempted to deviate from the Admiralty's fighting instructions were reminded of Mathews's fate.
