10 December 1710:  The battle of Villaviciosa in Spain on this day in which the Irish Brigades in the service of France and Spain played a distinguished part in the Victory. This was during the War of the Spanish Succession  between the two contenders for the Spanish Throne: Philip [Felipe] V backed by France and Charlesof Austria backed by Austria, England and Holland. During this see saw war the fortunes of both sides waxed and waned but after this campaign the Allies were never able to recover enough ground to regain their position. The battle took place about 70 miles north east of Madrid as Charles of Austria retreated towards Catalonia. Philip’s army hotly pursued him under the direct command of Marshal Vendome of France. 

Three Irish regiments fought with the Spanish army in this battle, commanded by respectively Col. Don Demetrio MacAuliffe, Col. Don John de Comerford and Col. Don Reynaldo Mac Donnell. They were collectively known as the Brigade of Castlelar. The Marshal’s army also included a force of Dragoons under the dashing cavalry commander General Count Daniel O’Mahony who was assisted by General Henry Crofton. To this ‘Arme Blance’ was attached a Lord Killmaloc’s Regiment of Dragoons. All of the Irish troops were to play a full part in the battle that materially affected the outcome of the War in Spain.

The engagement was fought on a bleak day in the midst of a Spanish Winter. The main action began in the early afternoon and after many hours of hard fighting it looked like that Charles had won. Marshal Vendome had even ordered the Retreat when his cavalry under the Marquis de Val-de-Canas and Count O’Mahony won the day by charging into the enemy’s rear and forced them to retreat. Only the onset of the darkness of a December night stopped them from destroying their opponents in detail. Though O’Mahony did manage to hamstring 700 mules that severely hampered the enemy from carrying away much of their material from the battlefield. 

Combined with the defeat and capture the previous day by Vendome of 5,000 English soldiers at the town of Brihuega the losses inflicted upon the enemy were such to render them unable to maintain the field and Charles had no option but to continue his sorry retreat to Barcelona and safety. His bid though for the Throne of Spain was effectively over.

Their brave and daring actions raised the status of the Irish troops and their leaders immeasurably during the Campaign of 1710. Though Lord Killmaloc was mortally wounded in the final battle the Count O’Mahony was awarded for his services.

The Comte de Mahoni acquired a great deal of glory on the battle-day of Villaviciosa, at the head of the dragoons. The King was so satisfied with him, that he conferred upon him a Commandership of the Order of St. Jacques (ie Jago) producing a rent of 15,000 Livres. …
