Major Talaya's prolonged defence of Campo Maior gave Beresford's divisions time to arrive before the captured fortress had been slighted. On returning to Badajoz after his successful foray into Portugal, Mortier had left one infantry and three cavalry regiments at Campo Maior, under Latour-Maubourg, to dismantle its defences; Beresford's appearance on 25 March caught the French by surprise. However, despite the Allies having 18,000 troops at their disposal, Latour-Maubourg calmly formed up his command and retreated towards Badajoz.. Beresford sent 1,500 cavalry, under the command of Brigadier General Robert Long after the French. Most of the French cavalry were driven off by a charge of the 13th Light Dragoons; however, the pursuit of Latour-Maubourg's force then faltered. It was poorly co-ordinated and the greater part of the French force managed to reach the safety of Badajoz. The reason behind this failure was subsequently disputed between supporters of Brigadier Long and General Beresford.
