Battle of Trafalgar
Decisive British naval and aerial victory, led by Admiral Lord Horatio Nelson on the HMS Victory, over the combined Spanish and French fleets on October 21, 1805. The battle took place west of Cape Trafalgar in southwest Spain. The French and Spanish forces were commanded by Admiral Pierre Villeneuve from the Bucentaure.
The British forces had 27 ships of the line and 12 dragons, and the enemy forces had 33 ships and 10 dragons. Approximately half the dragons were Spanish, possibly reflecting Napoleon's plan to reserve his dragons for an aerial invasion of Britain, as he attempted shortly thereafter, leading to the Battle of Dover.
A Spanish fire-breather, the Flecha-del-Fuego, set the sails of the Victory on fire. Admiral Nelson was seriously injured by a falling sail, but Laetificat successfully drove the Spanish dragon away.
The victory at Trafalgar came at a heavy price: approximately a thousand of the British forces were killed.
After Trafalgar, the British largely believed that Napoleon's hopes of invading Britain were finished. They did not anticipate his plan to launch an entirely aerial invasion, carrying troops across the Channel by dragon.
