Offensive attack by the horse troops in battles, representing a decisive moment. From the Middle Ages to the 19th century, the methods of this charge have changed according to the weapons and the tactics used. In the 17th century, the ‘caracole’ – successive attacks in the trot, followed by a half turn by the riders spread over a front line, after emptying their weapons – was the only strategy in use. In the 18th century, Maurice of Saxe, is the first one to understand that the cavalry must fight in an encounter with the other side and that its efficiency depends on its mass and speed. The cavalry’s charge in a gallop, invented by Maurice of Saxe, is then developed by Frederick of Prussia. The result is a new way of having a cavalry wing move – and a new conception of riding.
