The fiery O’Donnell was already on his way when this news reached him. The moment that he was sure that Augereau had left Barcelona and was retreating northward, he had resolved to fly to the relief of Lerida with the two divisions of which he could dispose. On the twentieth he marched from Tarragona by Valls and Momblanch, with 7,000 regular infantry, 400 horse, a single battery, and some 1,500 miqueletes. On the twenty-third he had reached Juneda, twelve miles from Lerida, without having seen a French picket or having been detected himself. He intended to drive off the few battalions blocking the bridge-head, and to open up communication with the besieged town that same day. Unfortunately for him, Suchet and Musnier had returned on the previous night from their expedition to Tarrega, and were now lying at Alcoletge, three miles north of the bridge-head, with seven battalions and 500 cuirassiers. Pushing briskly forward along the high-road, in a level treeless plateau, destitute of cover of any kind, the leading Spanish division--that of Ibarrola--came into contact about midday with the small force guarding the bridge-head, which was now in charge of Harispe, Suchet’s chief-of-the-staff. To the surprise of the Spaniards, who had expected to see these three battalions and two squadrons of hussars retire in haste, the French showed fight. Harispe was aware that Musnier could come up to his aid within an hour, and was ready for battle. His hussars charged the leading regiment of Ibarrola’s column, and threw it into disorder, while his infantry formed up in support. At this moment the Spanish general received news that Musnier was moving in towards his flank; he therefore retired, to get the support of O’Donnell, who was following him with the second division. But at the ruined village of Margalef, six miles from Lerida, the column of Musnier came up with Ibarrola, and he was so hard pressed that he formed line, with 300 cavalry on his right wing and his three guns on his left. The position was as bad a one as could be found for the Spanish division--a dead flat, with no cover. Musnier, on reaching the front, flung his cavalry, 500 cuirassiers of the 13th regiment, at the Spanish right wing. The horsemen placed there broke, and fled without crossing sabres, and the French charge fell on the flank battalion of the infantry, which was caught while vainly trying to form square. It was ridden down in a moment, and the horsemen then rolled up the whole line, regiment after regiment. A great part of Ibarrola’s corps was captured, and O’Donnell, who came on the field with the division of Pirez just as the disaster took place, could do no more than retire in good order, covering the scattered remnants of his front line. A Swiss battalion, which he told off as his rearguard, was pierced by the cuirassiers and for the most part captured. In this disastrous affair the Spaniards lost 500 killed and wounded and several thousand
