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, while in 1811 six regiments were converted to "Chevau-Legers Lanciers"; they were often used in battle to break the enemy's main resistance. In northern and eastern Europe they were employed as heavy cavalry, while in the Iberian peninsula they also fulfilled the role of lighter cavalry, for example in anti-guerrilla operations. In 1809, French dragoons scored notable successes against Spanish armies at the Battle of Ocana and the Battle of Alba de Tormes.
