Albuquerque’s operations, which ultimately turned out to be the most important section of the Andalusian campaign, need a word of explanation. It will be remembered that, early in January, he had assembled, at Don Benito and Medellin, the small field-force that he could command, after providing the garrison of Badajoz and leaving a detachment above Almaraz to watch the French 2nd Corps. It did not amount to more than 8,000 men, of which some 1,000 were cavalry. His position at Don Benito was intended to protect the flank of Zerain and Copons, who lay to his right, covering the passes that lead from Almaden on to Cordova. On January 15th he received from Zerain the news that he was about to be attacked at Almaden by a French column of at least 20,000 men. The Duke promptly began to march eastward to join his colleague, and reached Campanario on January 16th. Here he was met by the information that Zerain had been driven out of Almaden on the preceding day, and had drawn back by Benalcazar and Hinojosa on to the Seville road. Copons from Pozo Blanco was retiring in the same direction. The Duke thereupon concluded that his duty was to fall back by a route parallel to that of Victor’s advance, and to draw nearer to Seville, strengthening himself as he approached that city by Zerain’s and Copons’ small corps. Accordingly he sent off three of his weakest battalions to strengthen the garrison of Badajoz, which was very small at the moment, directed his artillery (with a cavalry escort) to take the good but circuitous high-road to Seville by Merida, Los Santos, and Santa Olalla, and started off across the mountains with his infantry and 500 horse. Marching very rapidly, though the roads were bad and the days short, he moved by Zalamea and Maguilla to Guadalcanal, on the borders of Andalusia, which he reached on January 18th. Here he received from the Central Junta an absurd order, apparently based on the idea that he was still at Campanario, which bade him stop Victor’s advance, by falling on his flank and rear by the road to Agudo and Almaden. But since the marshal had seized Almaden on the 15th, and was known to have moved southward from thence, it was clear that he must now be more than half-way to Cordova: if the Army of Estremadura plunged back into the mountains to seek Agudo and Almaden, it would only reach them on the 22nd or 23rd, and Victor would be at the gates of Cordova on the 21st. The Junta’s order was so hopelessly impracticable that the Duke took upon himself to disobey it, and wrote in reply that he should move so as to place himself between Victor and Seville, and would cover the Andalusian capital ‘so far as was possible with the small force at his disposition.’
