La Peña originally intended to take the right-hand road, and ordered Beguines, who was now in the high hills to the east, about Ximena, to join him with his roving brigade at Casas Viejas. The column left Facinas late in the evening, for La Peña had a great and misplaced belief in night marches, by which he always hoped to gain time on the enemy, since his moves could not be discovered or reported till the next morning. He overlooked the corresponding disadvantage of the extreme slowness of progress over bad roads in rugged country, the very real danger that the troops (or some of them) might miss their way in the dark, and the inevitable fatigue to the men from losing their proper hours of sleep. Graham’s laconic diary shows how this worked out. ‘Marched in the evening, very tedious from filing across water (the stream which fills the head of the lagoon of La Janda) and other difficulties. Misled by the guides on quitting the Cortigo de la Janda (farm at the head of the lagoon): the counter-march made a most fatiguing night.... It was twelve noon before the troops halted, having been nineteen hours under arms.’
The troops of Lardizabal, at the head of the column, had reached Casas Viejas in the morning, but the English division in the rear of the army had got no further than the northern end of the lagoon, some thirteen miles from their starting-place at Puente de Facinas. There was a violent east wind, the night had been very cold, and the men were much fatigued.
Lardizabal on reaching Casas Viejas had found the convent, which was the only solid building there, occupied by a French post, two companies sent out by General Cassagne from Medina Sidonia to watch the high-road. Thinking at first that he was only about to be worried by guerrilleros, the French captain shut himself up behind his barricades, instead of retreating at once. When he found out his mistake, and saw that a whole army was about him, it was too late to get off without loss. La Peña ordered that the convent should be left alone, as he did not wish to waste time in battering and storming it. The whole of his troops had come up, including the roving force of 1,600 men from the hills under Beguines, when the French unwisely made a bolt eastward, in the hope of escaping. The little column was pursued and cut up by a squadron of Busche’s German Hussars, many being killed and captured. From the prisoners and Beguines’s scouts La Peña learnt that Medina Sidonia was (contrary to his expectation) held by a serious force of French—Cassagne’s detachment being now composed of five battalions of infantry, a battery, and a cavalry regiment, about 3,000 men. The walls had been repaired, it was said, and the place was in a state of defence.
The Spanish general should have rejoiced to learn that Victor had sent an appreciable part of his army so far afield—fifteen miles from Chiclana—and by advancing he could have forced the Marshal to come to this distance from his lines in order to support Cassagne. A battle would no doubt have followed—but it was for a battle that the army had sailed to Tarifa. And by drawing Victor’s whole fighting force so far away from Cadiz, La Peña would have given a unique opportunity to the garrison to come out and destroy the siege-works. Meanwhile, if the French lost the battle they would be annihilated, being off their line of retreat; if they won it, they would return to find the greater part of the siege-works destroyed.
But this was not the line of thought that guided La Peña; he was, as his previous record showed, a shirker of responsibilities, and the prospect of a battle on the morrow, or the day after, seems to have paralysed him. To every one’s surprise he gave orders that the army, waiting till dusk had come on, should leave the Medina road, and march across country by a bad bridle-path to Vejer, on the other route from Tarifa to Cadiz. Graham protested against a second night march, after the experience of the first, and rightly, for news came in ere night that the road along the north side of the Barbate river, which La Peña had intended to use, was absolutely under water from inundations. La Peña therefore consented to wait till the next morning (March 3rd) and to use another country road, that between the north end of the La Janda lagoon and the river into which it falls. The army marched at 8 o’clock—Lardizabal as before in front, the English division in the rear. But on reaching the intended crossing-place, it was found that this road, like that north of the river, was flooded, the lagoon having overflowed at its northern end, and joined itself in one shallow sheet of water to the Barbate. Graham, on arriving at the passage, found the Spaniards halted at the edge of the flood, and apparently at a nonplus. The energetic old man took the business out of La Peña’s hands—he and his staff rode into the water, and sought personally for the track of the submerged causeway, which they fortunately found to be nowhere more than three feet under the surface of the flood. He placed men along the track at intervals, to guide those who should follow, and sat on his horse in the middle of the ford encouraging the troops as they marched past him. ‘I set the example of going into the water,’ he remarks in his diary, ‘which was followed by Lacy, the Prince of Anglona, and others. The passage lasted three hours, and would have taken double that time but for the exertions made to force the men to keep the files connected.’ It was 12 o’clock at night before the army reached Vejer—having taken fifteen hours to cover ten miles, owing to the delays at the inundation. Every one was wet through and much fatigued, for the weather was still very cold.
It remained to be seen what the enemy would make of this move; a squadron of French dragoons had been found in Vejer by the advanced guard, and driven out, so that it was certain that Victor would get prompt news that at any rate some part of the allied army had now appeared on the western road. The Marshal, as a matter of fact, was puzzled. On the night of the 2nd he had heard from Cassagne that the enemy was in force on the Medina Sidonia road, and had cut up the post at Casas Viejas. He accordingly sent orders to Cassagne to bid him stand firm, and promised to support him with his whole disposable force. But before dawn on the 4th he got news, from the dragoons expelled from Vejer, that there was a heavy force on the western road. Had La Peña transferred himself from one route to another, or were the Allies operating in two columns? Cassagne reported a little later that the column opposed to him had advanced no further, but that there were still Spanish troops on the Casas Viejas road; and this was true, for La Peña had left a battalion and some guerrilla horse at that place, to give him news of Cassagne, if the latter should move.
But there was also the garrison of Cadiz to be watched, and it was showing signs of activity. On the night of the 2nd-3rd, when the field army had been lying at Casas Viejas, General Zayas had, in accordance with the scheme of times left with him, thrown his bridge of boats across the Santi Petri creek, and passed a battalion across it, which entrenched itself on the mud-flat, facing the French works that cut off the peninsula of the Bermeja. They threw up a strong tête-du-pont, undisturbed, being under the protection of the heavy guns in the castle of Santi Petri, and other batteries on the Isle of Leon. The move could only mean that the garrison of Cadiz intended to come out. Accordingly Victor resolved to stop its egress; waiting for the dusk on the night of the 3rd-4th, he sent six companies of picked voltigeurs to storm the tête-du-pont. This they accomplished, the heavy guns failing to stop them in the dusk: the Spanish battalion in the work (Ordenes Militares) was nearly annihilated, losing 13 officers and 300 men killed or taken. But the bridge itself was saved by the prompt sinking of two of its boats, and was hastily floated back to the island, where Zayas laid it up for further use. He had been much chagrined at seeing and hearing nothing of allied forces behind the French, which he had been told to look for on March 3rd[144].
Putting together the movement of Zayas, and the fact that some at least of the allied army was now on the Vejer road, the Marshal came to the correct conclusion that the army in the field was intending to get into communication with Cadiz and its garrison. Accordingly he made a new plan to suit this hypothesis: of his three divisions one, that of Villatte, was to block the neck of the peninsula along which the track from Vejer and Conil leads to the Santi Petri creek and the Isle of Leon. The other two, concentrated at Chiclana, were to wait till the allied force had found itself blocked in front by Villatte, and then to fall upon its flank, in the space of three miles that lies between the hill of Barrosa and the position where Villatte had been posted. This plan would place the intercepting division in obvious danger, since, while attacked in front by the head of the allied army, it might find Zayas attempting once more to lay his bridge, and to take it in the rear. Such a movement by the garrison could not be stopped, because the end of the peninsula, by the bridge-place, was under the guns of several heavy batteries. But Victor directed Villatte not to fight to the last, but to be contented with holding the Allies in check long enough to enable the main body to fall on their flank. The sound of his guns would be the signal for the two striking divisions to move out from the wood of Chiclana, and dash at the long column whose head would be engaged with Villatte, while its tail would still be coming along the coast many miles to the rear. For 14,000 men had only the single line of communication along which to move.
