Captain General of Andalusia. He had been, however, a supporter of the Cortes; therefore, the new Regency removed him from this position and ordered him to Cádiz, along with his troops. La Peña was then the senior Spanish officer in Cádiz, and took command of the Spanish forces on the Isla de León. Battle of Barrosa In January 1811, a reduction of the French forces besieging Cádiz caused the British and Spanish allies garrisoning the city to launch an expedition in an attempt to raise the siege. Despite having authority, from the British government, to refuse to take part in a joint expedition of which he was not given command, Sir Thomas Graham—the British commander—agreed to cede command of the force to la Peña. Sailing from Cádiz between 21–24 February 1811, the Anglo-Spanish expedition regrouped at Tarifa on 27 February 1811 and marched towards the besieging French force's rear at Chiclana. A series of night marches, instigated by la Peña, however, resulted in a change of plan and the allied army ended up marching back towards Cádiz. The French commander, Marshal Victor, marched to meet the allied force with 10,000 men from his besieging army. On 5 March, la Peña's vanguard division met a French division straddling the main road to Cádiz and drove them off the road. Graham's rearguard division, meanwhile, was attacked by two of Victor's divisions. Graham split his force into two brigades; one to face each of the approaching French divisions. In the ensuing battle, Graham's forces beat off the French attacks despite la Peña entrenching his larger force on the isthmus to Cádiz and refusing to aid his British allies. La Peña further refused to pursue the retreating French troops, allowing them to resume the siege on Cádiz. The siege was not lifted until 24 August 1812. La Peña's actions in this engagement led to his court-martial where he was acquitted but relieved of command. References Bibliography ; ; ; ; ; ; .
