The battle of Navas de Membrillo took place on 29 December 1811 near Mérida, Spain, and saw the British light cavalry of General Rowland Hill assault a small Imperial French force led by Captain Neveux. During the action, the French soldiers formed in square inflicted a sharp defeat to the British cavalrymen. This engagement is considered by historian Ian Fletcher as "one of the more disappointing cavalry episodes in the Peninsula".
