At last Latour-Maubourg had given signs of life; this reconnaissance had been conducted by a flying column of two cavalry regiments and four battalions, under General Veilland, sent out to Olivenza from the camp of Girard’s division, with the very tardy purpose of hindering Beresford’s passage. Veilland reported to his chief that the enemy was across in such strength that he could do nothing. The appearance of 20,000 men on the Spanish bank of the Guadiana, so far to the south of Badajoz, placed Latour-Maubourg in a very delicate position: if he stayed twenty-four hours longer in his present camp close to Badajoz, he lost his communications with Andalusia, and might be pushed eastward up the Guadiana, out of touch with Soult, and having no retreat save towards the distant Army of the Centre. It was even possible that a rapid advance of the Allies might drive him into Badajoz, the last thing that he would desire. Accordingly he concentrated at Albuera, twelve miles south of that fortress, as a preliminary move, and prepared to fall back from thence by the great southern _chaussée_, towards Llerena and the Sierra Morena, where he would preserve, and shorten, his line of communication with Soult. Phillipon was left with 3,000 men in Badajoz, which was now quite beyond danger from a _coup de main_, and able to take care of itself for some weeks, till reinforcements should come up from Andalusia for its relief. With great unwisdom Latour-Maubourg left Olivenza garrisoned also; it was, as had been shown in January, contemptible as a fortress, even when held by a large force, and the French general placed in it only a single weak battalion of under 400 men. There were still on the walls the few guns that had been taken from the Spaniards--no more than fifteen were mounted, and several of these only on makeshift carriages. Why Latour-Maubourg chose to sacrifice a battalion it is hard to see; Napoleon wrote to Soult a month later to condemn the policy of small garrisons in the strongest terms[338]. At the best Olivenza, when so weakly held, could not hold out for more than a few days, and if Beresford had tried to rush it by escalade, when first he arrived before its walls, he must undoubtedly have succeeded, for 400 men cannot defend three miles of enceinte against a serious assault. There were some magazines in the place, and a small hospital of sick, who could not be removed[339]. But it was obviously absurd to throw away a battalion of sound men to keep them from capture for a few days. It has been suggested that Latour-Maubourg merely wanted to gain time[340]; but the time gained was trifling--Olivenza only held out five days--and might have fallen much sooner.
