The famous naval battle that occurred in 1805 during the Napoleonic Wars was the Battle of Trafalgar. This pivotal conflict took place off the southwest coast of Spain and pitted the British Royal Navy, commanded by Admiral Horatio Nelson, against the combined fleets of France and Spain. The battle resulted in a decisive victory for the British, establishing their naval supremacy for the remainder of the Napoleonic Wars. Nelson’s tactics, such as breaking the enemy's lines, were innovative and effective. Tragically, he was mortally wounded during the battle but became a celebrated hero in British history for his leadership and bravery.
