Over the course of its history, England has engaged in an uncountable number of battles, but a select few have been celebrated like the Battle of Trafalgar, one of the most important naval battles in history. Before the battle, Napoleon still harbored dreams of sailing an invasion force across the English Channel and subduing England, but that would be dashed on October 21, 1805 by a British fleet that was outnumbered and outgunned. The impact of Trafalgar cannot be overstated, as it literally set the stage for the rest of the Napoleonic Era. Unable to invade England, Napoleon was limited to conducting war on the European continent, and while he spent the better part of a decade frustrating the British and their allies, he was eventually undone at Leipzig and then Waterloo nearly a decade after Nelson's victory at Trafalgar.
For those questioning why generals continued using tactics from the Napoleonic Era even as technology changed the battlefield, the Battle of Austerlitz may provide the best answer. Napoleon is regarded as one of history's greatest generals, and Austerlitz was his greatest victory. In 1805, Britain, Austria, and Russia allied together to form the Third Coalition against the French, and the Third Coalition's forces consisted of armies from Austria and Russia, with Britain providing naval support as well as its financial powers. The Battle of Austerlitz was a tactical masterpiece that saw Napoleon actually invite an attack on his army by the bigger Coalition army, and over the course of about 9 hours, the French successfully defended their right flank while counterattacking in the center and splitting the Russo-Austrian army in two, allowing the French to hit the flank of the advancing left wing of the enemy. The result was a decisive victory that virtually annihilated the Third Coalition's army and made Napoleon the master of the European continent.
