In June 1811, the French occupied the Páramo Leonés. In response, Spanish troops under the command of Field MarshalJosé María Santocildes launched a strong attack against the French garrison at León, and forced the French to evacuate the city. The garrison commander of León, Brigadier General Jean-Baptiste Jeanin, destroyed several sections of the wall of the city, and on 19 June, retreated to Benavente. On 22 June, Santocildes and his forces entered in León, after 14 months of French occupation; the imminent arrival of French reinforcements, however, forced them to withdraw a short time later. Meanwhile, General Jean Pierre François Bonet moved from Asturias to León, concentrating his troops on the right bank of the riverÓrbigo. On the morning of 23 June, Brigadier General Jean-André Valletaux with 5,000 men, relieved the French garrison in the town of Benavides. At heavy cost to themselves, the French forced the Spanish to retreat, who withdrew having suffered few casualties. The French general then decided to attack General Francisco Taboada y Gil's troops who located in the small town of Cogorderos.
Battle
Despite having little knowledge of Taboada's troops, and possessing a smaller force than his opponent, Valletaux went on the attack. The Spanish fought tenaciously for more than four hours, until Brigadier General Federico Castañón arrived with three battalions of the Oviedo Regiment, which was commanded by Colonel Pedro Méndez de Vigo. In concert with Taboada's cavalry, the newcomers attacked the French flank and turned the tide of the battle. The Spanish launched three charges, inflicting heavy losses on the French, and after seven hours of battle, the French finally retreated, leaving behind a large amount of weapons and equipment, and several hundred of prisoners, including 11 officers. Valletaux himself was killed in the fighting, dying in the first Spanish charge. The Spanish captured three regimental eagles, and hunted down many of the French soldiers as they withdrew. Total French casualties amounted to 500 dead or wounded, while the Spanish lost 17 dead and 83 wounded.
Aftermath
Despite the victory, Taboada, threatened by the bulk of the army of General Jean Pierre François Bonet, retired to Astorga. However, Bonet and Marshal Jean-Baptiste Bessières suspended sending more troops to Extremadura, which favored Wellington's advance in the south. In July, the French army at León was reinforced with several thousand men under General Jean-Marie Dorsenne, who replaced Bessières. The next battle took place 27 August 1811 at Riego de Ambrós where the French, commanded by General André-Philippe Corsin, were defeated by Spanish troops led by Brigadier General Federico Castañón.
