Events now unfolded quickly. Lasalle had been reinforced with seven infantry battalions from Villatte, and once he saw the Spanish routing to the west he too ordered a powerful counter-attack. The 2nd Hussars regiment, accompanied by a regiment of Chasseurs à Cheval, smashed the Spanish cavalry, reformed, and charged at the once-again abandoned Spanish infantry in the eastern flank. Lasalle's fresh battalions also attacked frontally and French dragoons were now rolling over the center of the Spanish army, which attempted to flee in any way it could. Many were brutally killed in this chaotic retreat and Cuesta's army effectively ceased to exist.
