[231] Napoleon to Clarke, Oct. 30, 1809. [232] See for example Jan. 20, 1810, to Berthier; Jan. 31, to same; Feb. 12, to same. [233] _Correspondance_, vol. xx, Napoleon to Berthier, Feb. 12, 1810. Meanwhile the third great unit which was to form part of the projected Army of Portugal, the 2nd Corps (under the temporary command of General Heudelet[234]), was taking part in a separate and remote series of operations, far to the South. This corps, it will be remembered, had been left on the Tagus about Talavera and Oropesa, to protect the rear of Soult and King Joseph, when they marched in January with the 1st, 4th, and 5th Corps to conquer Andalusia. That exploit having been accomplished, Mortier went, with half of the 5th Corps, to attack Badajoz, and to subdue Estremadura, which Soult imagined to be defenceless, since Albuquerque had marched with the old Estremaduran army to save Cadiz. Mortier advanced unopposed to the walls of Badajoz, which he reached on February 12, but found himself unable to undertake its siege with his small force of 9,000 men, because a new Spanish host had just appeared upon the scene. La Romana, with three of the divisions of the army that had been beaten at Alba de Tormes in November, had marched down the Spanish-Portuguese frontier by the Pass of Perales; and on the same day that Mortier appeared in front of Badajoz, his vanguard arrived at Albuquerque, only twenty miles away. These divisions were 13,000 strong: La Romana could add to this force a few thousands more left behind by Albuquerque. Mortier rightly felt that he dare not commence the regular siege of Badajoz when he had such superior numbers in his front. He therefore asked for reinforcements, both from Soult and from King Joseph. The former could spare nothing from Andalusia at this moment, but the 2nd Corps was ordered to leave the Tagus and place itself in communication with Mortier. Heudelet had other projects on hand at the moment: he had just seized Plasencia on February 10, and was engaged in bickering with Carlos d’España and Martin Carrera, whom La Romana had left in the Sierra de Gata. But, in obedience to his orders, he called in his detachments, and marched by Deleytosa and Truxillo into the valley of the Guadiana. This movement, from the French point of view, was a hazardous one; by the transference southward of the 2nd Corps, a long gap was left between Ney at Salamanca and Heudelet and Mortier in Estremadura. No troops whatever covered Madrid from the side of the south-west and the valley of the Tagus, and an irruption of the English on this line was one of the dangers which Napoleon most dreaded[235]. He was unaware of Wellington’s deeply-rooted determination to commit himself to no more Spanish campaigns. [234] Soult had given up the 2nd Corps when he became King Joseph’s Major-General: Reynier, appointed to command it, had not yet appeared.
