Beside the 21,000 men of the 4th Army, who marched in the Anglo-Portuguese line under Castaños’s nephew General Giron[456], there was only one other Spanish force which Wellington intended to employ in his own operations. This was the so-called ‘Army of Reserve of Andalusia,’ which had to come up all the way from Seville, and was far too late to join in the campaign of Vittoria: it did not get to the front till July: even later than the Generalissimo expected. The origin of this corps was that, when Soult evacuated Andalusia in September 1812, the best-equipped of the Cadiz garrison troops joined the field-army of Ballasteros, and advanced with him to Granada. This body was in April 1813 known as the ‘Third Army’ and was now commanded by the Duque del Parque, the successor of the cashiered Ballasteros. But the remainder of the Cadiz garrison, which had not gone to the front, was organized during the winter into a separate unit, under Henry O’Donnell, the Conde d’Abispal. It was rather a miscellaneous assembly--seven of its fourteen battalions having been regiments which did not march in October 1812 because they were low in numbers or equipment, and three more newly-raised units, formed to replace in the Army List old regiments which had perished in previous campaigns. However, they were filled up with recruits, re-clothed and re-equipped, and Wellington intended to use them with his own army, as _étape_ and blockade troops. He preferred to take them with him rather than the 3rd Army, which was suspected of having many officers who had been devoted to Ballasteros, and who had resented the appointment of the new British generalissimo[457]. Moreover, O’Donnell was in every way a better officer than Del Parque, and had a good fighting reputation, though he was noted as impetuous and quarrelsome. The Army of Reserve of Andalusia was 14,000 strong, in two infantry divisions under Generals Echevari and Creagh and a weak cavalry brigade under Freire--late second in command of the Murcian army. The slow equipment of this corps, its late start, and its frequent halts for want of provisions, formed a perpetual source of dispute between Wellington and the Minister of War at Cadiz. But as it was not destined to form part of the original striking-force at the opening of the campaign, or to discharge any essential duty in the general scheme, its absence was not much felt. When it did appear, after Vittoria, it was usefully employed in blockading Pampeluna. But in the summer campaign of 1813 it must be remembered that Wellington employed no Spanish troops save the original 21,000 Galicians and Estremadurans under Giron, and Longa’s 4,000 Cantabrians, who joined in from the North ten days before Vittoria, and took a creditable share in that battle.
