The Situation in 1805
Trafalgar was fought on 21 October 1805 off Cape Trafalgar, on the southwest coast of Spain. The British Royal Navy, under Vice-Admiral Horatio Nelson, met a combined French and Spanish fleet commanded by the French Vice-Admiral Pierre-Charles Villeneuve. Spain had joined France in the war against Britain in late 1804, and Napoleon had considered an invasion of England, which required his navy to gain at least temporary control of the Channel.
By the time of the battle, that plan had already been dropped. Napoleon’s army had marched east in the late summer of 1805 to confront Austria and Russia, and it won at Austerlitz in December. Trafalgar was therefore not the battle that ended an invasion threat, as popular accounts sometimes imply. Its importance lies elsewhere: it confirmed British command of the sea for a long period.
The Fleets
The Combined Fleet had about 33 ships of the line, and Nelson’s fleet had 27. These large sailing warships, each a ship of the line, were the main weapon of the age. Villeneuve’s force was worn down by long blockades and cruising, and many of its crews were inexperienced, particularly in gunnery. British crews had spent long periods at sea and were generally better drilled, though they too had been kept afloat by hard service.
Nelson’s Plan
The standard fleet tactic of the day was to form a long line of battle, with each side’s ships passing along each other in parallel. Such battles were often indecisive. Nelson wanted something stronger. Before the battle he explained his intention in a memorandum to his captains, often called the Nelson touch, and he did so in person as well. He planned to approach in two columns, cut the enemy line in two places, and overwhelm part of it before the rest could help.
The approach had a cost. The leading British ships would be exposed to heavy fire as they closed, without being able to reply with full broadsides, since they were bows-on to the enemy. Nelson judged that the enemy’s poor gunnery and the speed of the approach would limit the damage. It was a calculated risk, based on his estimate of the opposing crews.
The Battle
The Combined Fleet was formed in a loose line, which was irregular and slow to reform. The British approached in two columns, one led by Nelson in his flagship Victory, the other by Vice-Admiral Cuthbert Collingwood in Royal Sovereign. Collingwood’s column engaged first. Nelson’s followed, and the Victory broke through the enemy line near Villeneuve’s flagship.
The fighting broke into a series of close ship-to-ship actions that lasted for several hours. Heavy guns fired at short range, and ships were often tangled together. Nelson was shot during the fight and died in the afternoon, after learning that the battle was going the British way. His famous signal before the engagement, “England expects that every man will do his duty”, is well attested, though the exact wording of other remarks attributed to him is less secure.
By evening, the British had captured or destroyed a majority of the Combined Fleet, which lost many ships while the British lost none. The French flagship was taken and Villeneuve captured. Casualties were heavy on both sides, particularly among the French and Spanish crews.
Storm and Aftermath
A gale arrived after the battle, and several prizes were wrecked or lost in the storm. A number of ships that escaped to Cadiz remained there, damaged and out of action. The French navy was never again able to threaten British control of the sea in the Napoleonic wars. Britain’s trade, and its ability to send armies overseas, continued almost without interruption. Manning that fleet had depended partly on press gangs, which supplied many of its sailors.
Why It Endured
Trafalgar’s long reputation owes something to Nelson’s death at the moment of victory, as well as to the quality of the result. HMS Victory survives today as a museum ship at Portsmouth. The lasting lesson of the battle lies in planning, training and willingness to depart from convention: the British did not win simply because of better ships, but because of better preparation and a clear plan.
