The battle of Waterloo took place in the Belgian province of Waterloo. It saw the defeat of Napoléon Bonaparte at the hands of the Duke of Wellington.
In a history project for school, Clyde Langer and Luke Smith were required to show the battle stratagies by Wellington and Napoleon at the battle. The pair re-enacted the battle on Mr Smith. (SJA: The Last Sontaran)
After the battle, Wellington told the Fourth Doctor, "'The only thing sadder than a battle lost, is a battle won." Some time later, the Doctor considered how right he was. (EDA: The Eight Doctors)
