Juan Carlos de Aréizaga
# Juan Carlos de Aréizaga

Juan Carlos Aréizaga y Alduncín (1756–1820) was a Spanish military commander.

Many historians of the Peninsular War, including Gómez de Arteche, Toreno, Clonard and Oman, agree that, while not questioning Aréizaga's personal courage, he lacked the necessary skills required of a general.

Oman was especially scathing in his assessment of Aréizaga's command at Ocaña:

   Even allowing for the fact that Areizaga had been the victim of the Junta's insensate resolve to make an offensive movement on Madrid, it is impossible to speak with patience of his generalship. For a combination of rashness and vacillation it excels that of any other Spanish general during the whole war. (Oman 1903: p. 96.)

## Early career

As a cadet in the Mallorca Infantry Regiment, Aréizaga saw action during the Invasion of Algiers in 1775, were he was badly wounded.

Promoted to Fusiliers captain in August 1790, he saw action in the defence of Oran and remained garrisoned there until October 1791.

Aréizaga retired as a colonel in 1805.

## Peninsular War

At the outbreak of the War, he marched towards Zaragoza, recruiting troops along the way and presented himself for duty to Castaños in November. After the defeat at Tudela, Francisco Palafox, then a commissioner for the Supreme Central Junta, gave Aréizaga command of an Infantry division.

Aréizaga was promoted to brigadier at the beginning of March 1809, and after raising troops in Mequinenza, in Aragón, near the fronitier with Catalonia, marched them to Tortosa. He then presented himself for duty at the Junta Central in Seville, and was promoted to field marshal at the beginning of May. He was then given command of the 3rd Division of Joaquín Blake's Army of Aragón, which was victorious at Alcañiz towards the end of the month, and for which he was promoted to lieutenant general. He was then defeated at María the following June and again, three days later, at Belchite. Following his retreat from that battle, Aréizaga was appointed governor of Lérida, until the end of September, when he was transferred to the newly formed Army of the Centre, under the interim command of General Eguía, whom he would succeed the following October.

Based on the combined movements of the Duke of Albuquerque's Army of Extremadura, the Duke del Parque's Army of the Left and Aréizaga's new Army of the Centre, the Junta Central, contrary to Wellington's advice, had prepared a plan expel the French troops from Madrid.

At the command of the new army, Aréizaga was routed by Marshal Soult at Ocaña, with about 4,000 Spaniards killed or wounded and 14,000 prisoners taken, as well as thirty flags and fifty of the sixty guns captured.

Following his overwhelming defeat, Aréizaga resigned, resignation that was not accepted, and he retreated down to Sierra Morena, where he was unable to prevent Soult from entering Andalusia and head towards Seville with seventy thousand troops, forcing the Supreme Central Junta to abandon that city and retreat down to Cádiz.

Having been flanked by Soult on 20 January 1810, Aréizaga retreated to Granada, where he handed over command to Blake the following week.

Appointed governor of Cartagena in August 1810, he remained in that post until the following December, when he was attached to Marquis de La Romana's 5th Army. He arrived at Cádiz in April 1811 to find that he should instead go to Alicante, where he was being investigated for the defeat at Ocaña. After 18 months at Alicante, in February 1813 he was ordered to return to Cádiz. From June to December 1813 he was stationed at Algeciras before going to Madrid after having been appointed member of the Cortes for Navarre. However, his appointment was annulled due to the case still open against him for the defeat at Ocaña.

## Post-war career

With Fernando VII back on the throne, Areizaga was appointed captain general of Guipúzcoa in July 1814, and that same month the case against him for Ocaña was dismissed. He continued as governor until his death in 1820.

During the Hundred Days Areizaga was also given command of the Observation Corps of the Left (Ejército de Observación de la Izquierda) until June 1815, when he handed over his command to Enrique O'Donnell.
