Admiral Pierre-Charles Villeneuve led the Franco-Spanish fleet out of Cadiz harbor under orders from Napoleon, unaware that Admiral Horatio Nelson's British fleet lay waiting nearby. The maneuvering on October 20th set up the climactic naval clash at Trafalgar on the 21st, which would cost Nelson his life but cement over a century of British naval supremacy.
Villeneuve had resisted sailing for weeks, doubting his fleet's readiness against Nelson's seasoned crews, but a letter from Napoleon accusing him of cowardice forced his hand. On October 20th, 33 French and Spanish ships of the line emerged from Cadiz into the Atlantic, moving in the loose, disorganized formation that would prove catastrophic the next morning.
Nelson, watching from a distance with 27 British ships, had already devised his unorthodox plan: rather than forming the traditional parallel battle line, he would drive two columns of ships directly through the enemy formation, accepting close-range chaos in exchange for decisive advantage. As the fleets shadowed each other through the day and into the night, sailors on both sides understood a major engagement was imminent. Nelson would die from a sniper's bullet the following afternoon, but not before his fleet destroyed the combined enemy force without losing a single ship of its own.
