During the Napoleonic Wars, dragoons generally assumed a cavalry role, though remaining a lighter class of mounted troops than the armored cuirassiers. Dragoons rode larger horses than the light cavalry and wielded straight, rather than curved swords. Emperor Napoleon often formed complete divisions out of his 30 dragoon regiments and used them as battle cavalry to break the enemy's main resistance. In 1809, French dragoons scored notable successes against Spanish armies at the Battle of Ocana and the Battle of Alba de Tormes.
