On July 13 the Spanish plan began to be carried out, Reding marching for Mengibar and Coupigny for Villa Nueva. Castaños kept quiet at Arjonilla, till his lieutenants should have reached the points which they were to attack. On the same day Dupont received the news of Moncey’s repulse before Valencia, and made up his mind that he must persevere in his defensive attitude, without making any attempt to mass his troops and fall upon the enemy in his front[143]. Just at the moment when his enemies were putting the game into his hands, by dividing themselves into three columns separated from each other by considerable gaps, he relinquished every intention of taking advantage of their fault.
On July 14 Reding appeared in front of the ferry of Mengibar, and pushed back beyond the river the outlying pickets of Liger-Belair’s detachment. He made no further attempt to press the French, but Dupont, disquieted about an attack on this point, ordered Gobert to bring down the remains of his division to Baylen, to join Vedel. Next morning the Spaniards began to develop their whole plan: Castaños appeared on a long front opposite Andujar, and made a great demonstration against the position of Dupont, using all his artillery and showing heads of columns at several points. Coupigny came down to the river at Villa Nueva, and got engaged with a detachment which was sent out from Andujar to hold the ford. Reding, making a serious attempt to push forward, crossed the Guadalquivir at Mengibar and attacked Liger-Belair. But Vedel came up to the support of his lieutenant, and when the Swiss general found, quite contrary to his expectation, a whole division deployed against him, he ceased to press his advance, and retired once more beyond the river.
Nothing decisive had yet happened: but the next day was to be far more important. The operations opened with two gross faults made by the French: Dupont had been so much impressed with the demonstration made against him by Castaños, that he judged himself hopelessly outnumbered at Andujar, and sent to Vedel for reinforcements. He bade him send a battalion or two, or even a whole brigade, if the force that he had fought at Mengibar seemed weak and unenterprising[144]. This was an error, for Castaños only outnumbered the French at Andujar by two or three thousand men, and was not really to be feared. But Vedel made a worse slip: despising Reding overmuch, he marched on Baylen, not with one brigade, but with his whole division, save the original detachment of two battalions under Liger-Belair which remained to watch Mengibar. Starting at midnight, he reached Andujar at two on the afternoon of the sixteenth, to find that Castaños had done no more than repeat his demonstration of the previous day, and had been easily held back. Cruz-Murgeon’s levies, which the Spanish general had pushed over the river below Andujar, had received a sharp repulse when they tried to molest Dupont’s flank. Coupigny had made an even feebler show than his chief at the ford of Villa Nueva, and had not passed the Guadalquivir.
But Reding, on the morning of the sixteenth, had woken up to unexpected vigour. He had forded the river near Mengibar, and fallen on Liger-Belair’s detachment for the second time. Hard pressed, the French brigadier had sent for succour to Baylen, whither Gobert had moved down when Vedel marched for Andujar. The newly arrived general came quickly to the aid of the compromised detachment, but he was very weak, for he had left a battalion at La Carolina and sent another with a squadron of cuirassiers to Liñares, to guard against a rumoured movement of the Spaniards along the Upper Guadalquivir. He only brought with him three battalions and 200 cavalry, and this was not enough to contain Reding. The 4,000 men of the two French detachments were outnumbered by more than two to one; they suffered a thorough defeat, and Gobert was mortally wounded. His brigadier, Dufour, who took over the command, fell back on Baylen, eight miles to the rear. Next morning, though not pressed by Reding, he retired towards La Carolina, to prevent himself being cut off from the passes, for he credited a false rumour that the Spaniards were detaching troops by way of Liñares to seize the Despeña Perros.
Dupont heard of Gobert’s defeat on the evening of the sixteenth. It deranged all his plans, for it showed him that the enemy were not massed in front of Andujar, as he supposed, but had a large force far up the river. Two courses were open to him—either to march on Baylen with his whole army in order to attack Reding, and to reopen the communications with La Carolina and the passes, or to fall upon Castaños and the troops in his immediate front. An enterprising officer would probably have taken the latter alternative, and could not have failed of success, for the whole French army in Andalusia save the troops of Belair and Dufour was now concentrated at Andujar, and not less than 15,000 bayonets and 3,000 sabres were available for an attack on Castaños’ 12,000 men[145]. Even if Coupigny joined his chief, the French would have almost an equality in numbers and a great superiority in cavalry and guns. There cannot be the slightest doubt that the Spaniards would have suffered a defeat, and then it would have been possible to expel Reding from Baylen without any danger of interference from other quarters.
But, in a moment of evil inspiration, Dupont chose to deprive himself of the advantage of having practically his whole army concentrated on one spot, and determined to copy the error of the Spaniards by splitting his force into two equal halves. He resolved to retain his defensive position in front of Andujar, and to keep there his original force—Barbou’s infantry and Frésia’s horse. But Vedel with his own men, the four battalions from Gobert’s division which were at Andujar, and 600 cavalry, was sent off to Baylen, where he was directed to rally the beaten troops of Dufour and Liger-Belair, and then to fall upon Reding and chase him back beyond the Guadalquivir[146].
On the morning, therefore, of July 17 Vedel set out with some 6,000 men and marched to Baylen. Arriving there he found that Dufour had evacuated the place, and had hurried on to La Carolina, on the false hypothesis that Reding had pushed past him to seize the passes. As a matter of fact the Spaniard had done nothing of the kind: after his success at Mengibar, he had simply retired to his camp by the river, and given his men twenty-four hours’ rest. It was a strange way to employ the day after a victory—but his quiescence chanced to have the most fortunate effect. Vedel, on hearing that Dufour had hastened away to defend La Carolina and the passes, resolved to follow him. He was so inexcusably negligent that he did not even send a cavalry reconnaissance towards Mengibar, to find out whether any Spanish force remained there. Had he done so, he would have found Reding’s whole division enjoying their well-earned siesta! In the direction of La Carolina and the passes there was no enemy save a small flanking column of 1,800 raw levies under the Count of Valdecañas, which lay somewhere near Liñares.
