From Burgos Marshals Ney and Victor were dispatched with their divisions to act on the rear of Castaños, and cut off his retreat, while Lasnes, with 30,000 men, should attack him in front. This last remaining army of the Spaniards is represented by the French as consisting of 80,000 men, of whom three-fourths were armed. But the nominal force of the conjoined armies under Castaños and Palafox was only 65,000, and the effective soldiers hardly more than half that amount. Many of the Andalusian troops had returned to their homes after the first success, and many more had remained at Madrid, so that though some thousands (mostly from Valencia) had joined Castaños, his force was little more numerous than it had been at Baylen. His own opinion was decidedly against risking an action in which there could be no reasonable hope of advantage; but the commissioner, D. Francisco Palafox, to whom the power of overruling the General had been madly entrusted by the Central Junta, determined that a battle should be fought, and Castaños therefore was compelled to fight, lest he should be stigmatized as a traitor, and murdered by his own men, or torn to pieces by a mob. Already the Conde de Montijo, who left the army at this time, was every where accusing him of treachery, because he had warmly opposed a determination, the fatal consequences of which he certainly foresaw. ♦BATTLE OF TUDELA.♦ The plan of the French against this army was the same as that which they had practised against Blake’s; they meant to rout it by a powerful attack in front, and to destroy the fugitives by intercepting them with a second force in their flight. Their destruction was considered to be as certain as their defeat, but Ney was less expeditious in his movements than had been calculated; and Castaños hearing on the 21st that this corps was advancing upon Soria, while Lasnes and Moncey approached from the side of Logroño and Lodosa, abandoned Calahorra and fell back upon Tudela. On the 22d Lasnes entered Calahorra and Alfaro, and at daybreak on the following morning he found the Spaniards drawn up in seven divisions, with their right before Tudela, and their left extending along a line of from four to five miles upon a range of easy heights. The Aragonese, who had joined only a few hours before by forced marches, were on the right, the Valencians and the troops of New Castille in the centre, the Andalusians on the left. Their line was covered by forty pieces of artillery. Situations were chosen by the enemy for planting sixty pieces against them; but upon seeing their own relative strength, and the confusion which was observable among the Spaniards, they preferred a more summary mode of attack. General Maurice Mathieu, with a division of infantry, forced the Spanish centre; and General Lefebvre, with the cavalry, passing through, wheeled to the left, and coming in the rear of the Aragonese, at a time when that wing, having withstood an attack,
