In early 1810 Wellington obtained intercepted secret letters from Marshall Soult to the King of Spain of the planned attack on Ciudad Rodrigo. The bulk of the army was moved into northern Portugal. On 1 March Craufurd’s Light Brigade become The Light Division. Initially he had 2,500 men from the first battalions of the 43rd, 52nd and 95th together with a troop of horse artillery and one regiment of 500 cavalry from the 1st Hussars of the King’s German Legion. On 28 March these were augmented by 1,000 men from two battalions of Portuguese Caçadores, the 1st and 2nd. The latter of these units was afterwards changed for the 3rd, which was reckoned the most efficient corps that could be selected from Marshal Beresford’s command. The cavalry force was also increased by two squadrons of the 16th Light Dragoons and, in early July, by the addition of three squadrons of the 14th Light Dragoons.
