Battle of Trafalgar

The Battle of Trafalgar was fought on the 21st of October 1805 off Cape Trafalgar on the Spanish coast, between the combined fleets of Spain and France and the Royal Navy. It was the last great sea action of the period and its significance to the outcome of the war in Europe is still debated by historians.

The battle itself was the culmination of a long campaign. After the Treaty of Amiens Europe was at peace for 14 months. Many ships in the Royal Navy were paid off and the British returned to their peace time activities. But across the Channel in France Napoleon was planning the next stage of his domination of Europe. He realised that if war broke out again then the Royal Navy would blockade French and continental ports as they had done before and French overseas trade would be crippled. So he planned to invade England and free the seas for French trade. He ordered the building of a fleet of invasion barges and the Grand Army was moved to the Pas de Calais area.
But to get the army across safely the French fleet would need to control the English Channel. To this end he tried to engineer a meeting of his fleets so they could control the sealanes, and protect his invasion barges. He gave orders for the fleets in Toulon, Brest and Ferrol to break out of their blockaded ports.

The battle was the most decisive naval victory of the war. Twenty-seven British ships of the line led by Admiral Lord Nelson aboard HMS victory defeated thirty-three French and Spanish ships of the line under French Admiral Pierre-Charles Villenueve off the southwest coast of Spain, just west of Cape Trafalgar, in Caños de Meca. The Franco-Spanish fleet lost twenty-two ships, without a single British vessel being lost. The Royal Navy annihilated the greatest threat to British security for 200 years.

Nelson discovered that Villeneuve had sailed out of the Med and resumed the chase on the 10th May across the Atlantic to the West Indies. Eventually following the French and Spanish fleet back again to Europe. Villeneuve waited for Ganteaume to join him. But Ganteaume failed to break the British blockade, so Villeneuve sailed back for Ferrol.
He encountered Calders squadron of 15 battleships off Cape Finisterre on 22nd of July. They fought an abortive action in poor visabilty. Calder captured two French ships, and several of the British ships were damaged. Calder failed to press home the action, for which he was severely criticized.
(After Calder joined up with Nelsons fleet he was allowed to sail back to England on the Prince of Wales in an attempt to clear his name at a court martial. The Prince of Wales was a powerful 98 gun ship, and Nelson could ill afford to lose it.)

The British frigate made the signal 370, 'Enemy's ships are coming out of port', which was repeated along the chain of ships until it reached the main fleet. Nelson then signaled the fleet for 'general chase south-east', his plan was to steer for the Straits of Gibraltar and prevent the Combined Fleet from sailing into the Mediterranean.
