The greatest cavalry charge of modern history was at the 1807 Battle of Eylau, when the entire 11,000-strong French cavalry reserve, led by Joachim Murat, launched a huge charge on and through the Russian infantry lines. Cavalry's dominating and menacing presence on the battlefield was countered by the use of infantry squares. The most notable examples are at the Battle of Quatre Bras and later at the Battle of Waterloo, the latter which the repeated charges by up to 9,000 French cavalrymen ordered by Michel Ney failed to break the British-Allied army, who had formed into squares.
