Quick answer

Who won the Battle of Trafalgar?

Britain won a decisive victory at Trafalgar on 21 October 1805, when Admiral Horatio Nelson broke the combined fleet of France and Spain off the Spanish coast. Nelson was killed at the moment of triumph, but the victory ended, for a generation, any hope of challenging Britain at sea.1

On a swell off the Spanish coast, one fleet gambled everything on breaking the rules of naval war. At Trafalgar, Admiral Horatio Nelson won the most complete sea victory of the age and paid for it with his life. It ended, for a generation, any hope of challenging Britain at sea.2

The road to the Channel

Napoleon wanted to invade Britain, and for that he needed control of the sea, even for a few days. The task fell to a combined French and Spanish fleet under Admiral Villeneuve. In the spring of 1805 Villeneuve sailed from Toulon to the West Indies to draw the British away, with Nelson in pursuit, and then turned back for Europe. On 22 July he fought an indecisive action off Cape Finisterre against a British squadron under Sir Robert Calder and then, instead of making for the Channel, put into Cadiz, where the British blockaded him.3

By October 1805, however, the invasion had been shelved, and the fleet was ordered into the Mediterranean, toward Naples. Villeneuve obeyed reluctantly, and both the National Museum of the Royal Navy and the Fondation Napoléon note that he sailed expecting to be replaced in command. It began to leave Cadiz on 19 October, 33 ships of the line strong, and two days later met Nelson's 27 near Cape Trafalgar.4

According to the National Museum of the Royal Navy, light winds slowed the departure, and the combined fleet had been ordered back toward Cadiz when the British closed in on the morning of the 21st. Nelson and Napoleon never met in battle, but here the admiral denied the emperor the sea, the contrast at the heart of Nelson vs Napoleon.5

How many ships fought at the Battle of Trafalgar?

Sixty ships of the line fought at Trafalgar: 27 British against 33 French and Spanish. Britannica divides the combined fleet into 18 French and 15 Spanish ships. Royal Museums Greenwich puts the crews at nearly 30,000 men and 2,632 guns on the allied side, against about 18,000 men and 2,148 guns under Nelson. The British were outnumbered in ships, men and guns.6

Nelson's fleet was not in good shape either. Royal Museums Greenwich notes that it lacked numerical superiority and had suffered from cost cuts at the Admiralty, so his plan rested on the skill of his officers and crews rather than the weight of his ships. The National Museum of the Royal Navy makes the same point: Nelson was sure that better-drilled British crews would fire faster than their opponents.7

What was the Nelson touch?

The "Nelson touch" was Nelson's own name for his battle plan at Trafalgar. Instead of forming a line parallel to the enemy, his fleet would attack in two columns: one under Nelson aimed at the enemy center and flagship, the other under Collingwood at the rear. He explained it to his captains over dinner aboard HMS Victory.8

Royal Museums Greenwich dates Nelson's departure from Portsmouth in Victory to 14 September 1805, and the National Museum of the Royal Navy has him joining the fleet off Cadiz on 28 September and laying out the plan at dinner the next day. The idea was a calculated risk: by driving straight at the enemy, the leading British ships would take fire they could not answer, but the battle would then become a close-range fight decided by gunnery, the arm in which the Royal Navy was strongest. The National Museum of the Royal Navy also stresses the trust behind it, since Nelson left his captains free to use their own judgment within the plan.9

Nelson breaks the rules

For a century, fleets had mostly fought in parallel lines, trading broadsides at a distance. Others had broken an enemy line before, at the Saintes in 1782 and Camperdown in 1797, but Nelson built his whole battle around it. He drove his ships in two columns straight at the enemy line, head-on, to cut it into pieces and force the close, chaotic melee where British gunnery and seamanship were unmatched.10

Nelson led one column in HMS Victory, while Vice-Admiral Cuthbert Collingwood in HMS Royal Sovereign led the other against the enemy rear. Royal Museums Greenwich times the first sighting at about 6 a.m. and Nelson's order to prepare for battle at 6:40 a.m. With so little wind, the British columns closed at a walking pace, and the ships at their head had to bear the enemy's first broadsides. At 11:45 a.m. Nelson's signal went up: “England expects that every man will do his duty.”11

He aimed not to fight the enemy line, but to cut it in three and destroy it piece by piece.

The melee

According to the timeline of Royal Museums Greenwich, Villeneuve signaled his fleet to engage at 11:50 a.m., and the French Fougueux fired the first shots at Collingwood's Royal Sovereign. Collingwood reached the allied line first and fired a broadside into the Santa Ana, one of the Spanish flagships, and Nelson first steered for the great Spanish Santísima Trinidad before turning on Villeneuve's flagship, the Bucentaure. Both museums describe Collingwood's division falling on the allied rear, and Victory dealing the Bucentaure a knockout blow as she passed.12

The columns punched through and the battle dissolved into dozens of ship-to-ship duels at point-blank range. Victory became locked alongside the French Redoutable, opening a gap through which the ships astern poured into the allied center. British crews, faster at reloading and steadier under fire, took enemy ship after enemy ship. Nelson's flagship HMS Victory drove into the heart of it.13

How long did the Battle of Trafalgar last?

The Battle of Trafalgar lasted five to six hours. Firing began just before noon, and Royal Museums Greenwich dates the end of the firing to 5:30 p.m., while the National Museum of the Royal Navy says the battle was over by around 5 p.m. The Fondation Napoléon speaks of four hours of especially fierce fighting.14

The approach took far longer than the battle itself. The fleets had been in sight of each other since dawn, but the light wind meant that nearly six hours passed between the first sighting and the first shot.15

How did Nelson die at Trafalgar?

Nelson was shot at about 1:15 p.m. by a marksman in the rigging of the French Redoutable while he paced Victory's quarterdeck with Captain Thomas Hardy. The ball pierced a lung and passed through his spine. He was carried below and died at 4:30 p.m., after learning that the battle was won.16

At the height of the fighting a marksman in the mizzen top of the French ship Redoutable, locked alongside Victory, shot Nelson down on his own deck. The National Museum of the Royal Navy describes the ball entering at the left shoulder and cutting through a lung and a major artery before striking the spine.

Accounts differ by twenty minutes on the time of the shot: Royal Museums Greenwich gives 1:15 p.m. in its timeline but 1:35 p.m. in its Nelson chronology. He was carried down to the orlop deck, where his surgeon, William Beatty, recorded his death at half past four. He lived just long enough to learn the battle was won. Beatty recorded his last words as “Thank God, I have done my duty,” and he died a national legend.17

How many died at the Battle of Trafalgar?

About 4,400 to 4,550 French and Spanish sailors and soldiers were killed at Trafalgar, against 449 British dead. Royal Museums Greenwich counts 4,408 allied dead and 2,545 wounded, while the Fondation Napoléon gives 3,499 French and 1,050 Spanish killed. British wounded numbered about 1,200, by both counts.18

Thousands more on the allied side were taken prisoner, but the totals vary widely between accounts. Britannica sums up the combined fleet's loss as about 14,000 men, half of them prisoners, and about 1,500 British killed or wounded. In ships, the National Museum of the Royal Navy counts 18 of the 33 captured or destroyed on the day, with 4 more that escaped only to be taken two weeks later and 11 that struggled back into Cadiz. Britannica counts 19 lost on the day (19 or 20 in its main entry).19

What happened in the storm after the battle?

A gale struck the day after Trafalgar and raged until 27 October. Collingwood, now in command, took the fleet out to sea instead of anchoring, and most of the captured ships were wrecked or lost on the Spanish coast near Cadiz. When the storm ended, only four prizes remained in British hands.20

Among the prizes lost in the first night were the Fougueux, the Redoutable and the Algeciras. Britannica credits Collingwood with the hard task of saving the battered fleet and its prizes through the storm, and not a single British ship was lost. The prize money the crews would have earned sank with the captured ships, and the government later made a special grant to compensate them. Beatty, who had preserved Nelson's body in a cask of brandy aboard Victory, describes the gale breaking that same evening. The battered Victory, taken in tow by HMS Neptune, reached Gibraltar on 28 October, as Beatty, who was aboard, records.21

What happened to Villeneuve after Trafalgar?

Villeneuve was captured at Trafalgar and taken to England as a prisoner. He was released in the spring of 1806 and returned to France, where on 22 April 1806 he took his own life in an inn at Rennes, according to both Britannica and the Fondation Napoléon.22

Britannica says he had been waiting in Rennes to learn how far Napoleon blamed him for the disaster. The Fondation Napoléon, drawing on the Dictionnaire Napoléon, adds that he had been freed on parole in April and that he stabbed himself six times in the chest.23

Why was the Battle of Trafalgar important?

Trafalgar destroyed the combined fleet and gave Britain a command of the sea that, in Britannica's judgment, lasted more than a hundred years. It put a decisive end to Napoleon's plans to invade Britain, already shelved that autumn. On land it changed little at first: Royal Museums Greenwich notes that six weeks later Napoleon won at Austerlitz.24

Around two-thirds of the combined fleet was captured or destroyed; the British lost not a single ship. By that autumn Napoleon had already turned inland toward Austria, where he would soon triumph at Austerlitz. The war on land went on for another decade, until Waterloo in 1815. The news reached London in the early hours of 6 November, and the public mood was divided between joy at the victory and grief for Nelson.25

Collingwood was made a baron, and every captain received the Naval Gold Medal. But the sea was settled: for the next hundred years, Britain ruled it, and Trafalgar became the measure of a decisive victory. It belongs among the greatest naval battles in history. With Hastings, Waterloo and the Battle of Britain, it is one of the battles most often named as the most important in British history.26

Where was the Battle of Trafalgar fought, and what is there today?

The battle was fought in the Atlantic west of Cape Trafalgar, a headland on the southwestern coast of Spain between Cadiz and the Strait of Gibraltar. Its memory lives on in London's St Paul's Cathedral, where Nelson is buried, and aboard HMS Victory in Portsmouth.27

Nelson's body was brought home and, after lying in state in the Painted Hall at Greenwich, was buried beneath the dome of St Paul's after a state funeral on 9 January 1806. The National Museum of the Royal Navy notes that he was the first person outside the royal family to receive a state funeral at St Paul's. Victory herself has stood in No. 2 dry dock at Portsmouth since 12 January 1922, and, as the museum notes, the spots where Nelson fell and where he died are marked on board.28
