Battle of Trafalgar

The Battle of Trafalgar was a naval engagement that took place on 21 October 1805 between the Royal Navy and a combined fleet of the French and Spanish navies during the War of the Third Coalition. As part of Napoleon's planned invasion of the United Kingdom, the French and Spanish fleets combined to take control of the English Channel and provide the Grande Armée safe passage. The allied fleet, under the command of French admiral Pierre-Charles Villeneuve, sailed from the port of Cádiz in the south of Spain on 18 October 1805. They encountered a British fleet under Lord Nelson, recently assembled to meet this threat, in the Atlantic Ocean along the southwest coast of Spain, off Cape Trafalgar.

Nelson was outnumbered, with 27 British ships of the line to 33 Franco-Spanish ships, including the largest warship in either fleet, the Spanish Santísima Trinidad. To address this imbalance, Nelson sailed his fleet directly at the allied battle line's flank, hoping to break the line into pieces. Villeneuve had worried that Nelson might attempt this tactic, but for various reasons, failed to prepare for it. The plan worked almost perfectly; Nelson's columns split the Franco-Spanish fleet in three, isolating the rear half from Villeneuve's flag aboard Bucentaure. The allied vanguard sailed off while it attempted to turn around, giving the British temporary superiority over the remainder of their fleet. In the ensuing fierce battle 18 allied ships were captured or destroyed, while the British lost none.

The offensive exposed the leading British ships to intense crossfire as they approached the Franco-Spanish lines. Nelson's own HMS Victory led the front column and was almost knocked out of action. Nelson was shot by a French musketeer during the battle, and died shortly before it ended. Villeneuve was captured along with his flagship Bucentaure. He attended Nelson's funeral while a captive on parole in Britain. The most senior Spanish commander, Admiral Federico Gravina, escaped with the surviving third of the Franco-Spanish fleet; he died six months later of wounds sustained during the battle. The victory confirmed British naval supremacy, and was achieved in part through Nelson's departure from prevailing naval tactical orthodoxy.
