On the twenty-sixth and twenty-seventh the French cavalry failed even to get in touch with Del Parque’s rearguard, and found nothing but a few stragglers on the road. But on the afternoon of the twenty-eighth the leading squadrons reported that they had come upon the whole Spanish army encamped in a mass around the town of Alba de Tormes. The duke had flattered himself that he had shaken off his pursuers, and was surprised in a most unfortunate position. Two of his divisions (Ballasteros and Castrofuerte) were beyond the Tormes, preparing to bivouac on the upland above it. The other three were quartered in and about the town, while the cavalry was watching the road, but had fallen in so close to the main body that its vedettes gave very short notice of the approach of the enemy. Kellermann was riding with the leading brigade of his cavalry--Lorcet’s _chasseurs_ and hussars; the six regiments of dragoons were close behind him, so that he had over 3,000 sabres in hand; but the infantry was ten miles to the rear. If he waited for it, Del Parque would have time to cross the river and take up a defensive position behind it. The French general, therefore, resolved to risk a most hazardous experiment, an attack with unsupported cavalry upon a force of all arms, in the hope of detaining it till the infantry should come up. The Spaniards were getting into line of battle in a hurry, Losada’s division on the right, Belveder’s and La Carrera’s on the left, the cavalry--1,200 sabres at most--in their front. The divisions beyond the river were only beginning to assemble, and would take some time to recross the narrow bridge: but 18,000 men were on the right bank prepared to fight.
