Meanwhile Cassagne, at Medina Sidonia, was sent orders to find out exactly what was in front of him, and if there was no solid force, to march to join the main body on the morning of the 5th. He must have received the order to do so somewhere in the afternoon of the 4th.

Victor’s force was not so large as he would have wished. Soult had taken from him six battalions of infantry and three cavalry regiments, reducing the total of the 1st Corps left at or near Cadiz to twenty-three battalions of infantry, three regiments of cavalry, and four or five field batteries, about 15,000 men in all. There were also present in the lines 3,500 men more not belonging to the corps, viz. about 1,000 artillery and 800 engineers and sappers belonging to the siege train, and 1,600 marine troops from the flotilla which had been constructed in Cadiz bay. These of course were useless for field operations; but they served to man the lines, with the addition of three battalions—2,000 men—from the fighting force, the least that Victor thought he could spare. For the garrison of Cadiz and the English fleet might attack in force any point of the Lines during the absence of the main body. This left 13,000 men available for field operations: but Cassagne was still absent at Medina Sidonia, with five battalions, a battery, and one of the three cavalry regiments, making 3,100 men in all. There were therefore only 10,000 men left to face La Peña and Graham, till Cassagne should come up. Victor, according to his own dispatch, much over-estimated the force of the Allies, which he states as 8,000 English and 18,000 Spaniards, so that he went to work in rather a desperate mood, thinking that he had to fight very superior numbers, and that his only chance was to make a sudden and resolute attack when he was not expected. As a matter of fact he overstated the enemy by nearly a half, since there were really marching from Vejer only 5,000 English and under 10,000 Spaniards altogether, and no help could come to them from Cadiz till Villatte should be driven off.

Each of the three divisions which Victor had under his hand was short of several battalions; Ruffin’s, the 1st Division, and Leval’s, the 2nd, had each a battalion in the Lines and another detached with Cassagne at Medina. Villatte’s, the 3rd, had one in the Lines and three with Cassagne. Hence they took the field, Ruffin and Leval with six battalions each, Villatte with five only. The respective forces were 3,000, 3,800, and 2,500 bayonets[145]: each unit had its divisional battery with it. Of the two cavalry regiments, the 1st Dragoons, 400 sabres, was with Ruffin, the 2nd Dragoons, 300 sabres, with Villatte. On the evening of the 4th Ruffin’s and Leval’s men were concentrated at Chiclana, hidden behind the woods which cover it; Villatte was on the ridge of the Torre Bermeja, between the Almanza creek and the sea, right across the track leading from Vejer to Cadiz, and looking both backward and forward, with his attention ready for Zayas as much as for La Peña.

Meanwhile the Allies were marching straight into the middle of the trap which Victor had prepared for them. After passing Conil, the road on which their army was moving turns inland towards Chiclana, while a mere track follows the beach towards the Santi Petri. It was along this that La Peña was intending to move. But in the dark the head of the column followed the main road, and went several miles along it. At dawn the error was discovered, and the army, cutting across an open heath, got down to the beach[146].

The point which the allies had now reached was a mile or so south-east of the coast-guard tower of Barrosa, where an isolated eminence called the Cerro del Puerco (Boar’s Hill), crowned by a ruined chapel, looks out upon the heathy plain of Chiclana to the north, and a scrubby pine wood (covering much of the ground towards the beach) to the west[147]. The advanced cavalry got upon the hill unhindered soon after daybreak, and met no enemy, nor did patrols sent into the wood discover him for some time. Presently, however, news came back from the front that a French force had been discerned, drawn up between the Almanza creek and the sea, and blocking the way to Cadiz. Being outside the wood it was very visible, and seemed to be about a strong brigade of infantry with a squadron or two of horse. This was, of course, Villatte, waiting for the advance of the Allies. No other hostile troops were to be seen.

La Peña now told Graham that, despite of the fact that the men had been under arms for fourteen hours, and had marched as many miles in the dark, he was about to thrust this French force out of the way without a moment’s delay. Lardizabal, with the vanguard division, was to attack it at once, while the rest of the army took up a position to cover him from any possible movement of the enemy from the direction of Chiclana.

About nine in the morning Lardizabal with his five battalions reached Villatte’s front, deployed and attacked him. The forces were about equal, and the attack was repulsed with some loss; La Peña then ordered up the leading brigade of Anglona’s division to support the vanguard. A sharp engagement was going on, when a new fire broke out behind Villatte. Zayas, from the Isle of Leon, had recast his bridge across the Santi Petri, and was advancing to take the French in the rear. Villatte saw his danger, gave up his position across the peninsula, and hastily fell back towards the passage of the shallow Almanza creek, near the mill of the same name. He recrossed it, not without some difficulty, and then drew up to defend the passage. Lardizabal was prevented by La Peña from pursuing him, and halted opposite. The skirmish had been hot: Villatte had lost 337 men, the Spaniards a few more. But they had achieved their purpose, and the connexion with Cadiz had been duly established.

About noon La Peña sent orders to Graham to evacuate the Barrosa position, and draw in closer to the Almanza creek, to join the rest of the army. Meanwhile he would be relieved on the hill by five battalions of Cruz Murgeon and Beguines[148], to which rearguard there was added one British battalion, Browne’s composite unit consisting of the six flank companies of the 9th, 28th, and 82nd. Whittingham and the cavalry were to flank this force on the coast track, somewhere near the tower of La Barrosa. This force was to move off in its turn, when Graham should have reached the main body, for the Spanish general had resolved not to hold the Cerro, considering that an army of 14,000 men should not be spread out over four miles of ground, but be kept more concentrated. Graham entirely disagreed with this movement; if the Allies came down and crammed themselves into the narrow peninsula between the sea and the Almanza creek, there was nothing to prevent Victor from seizing the Barrosa heights, and placing himself across their front, in a way which would block them into the cramped position which they had assumed. The move practically threw them back on Cadiz, and sacrificed all the results of the toilsome flank march in which they had been so long engaged. Graham had in the morning urged on La Peña the all-importance of retaining the hill, but now saw his advice rejected. Obeying orders, however, he set his column in march towards the Torre Bermeja and the Almanza creek, through the pine wood. At the same time the rearguard under Beguines and Cruz Murgeon ascended the Cerro, and took up the post which the British division had left.

The British column did not descend to the rough track along the coast, but used a fair wood path right through the middle of the pine forest, which saved them a couple of miles of détour, and was practicable for artillery. They were soon filing along between the pines, lost to sight, and themselves unable to see a hundred yards in any direction.

At this moment, about 12.30 p.m., Victor suddenly broke out of the woods in front of Chiclana with the 7,000 men of Ruffin’s and Leval’s divisions. He was tired of waiting for Cassagne, for he had now got news that the force at Medina had started late in the morning, instead of at dawn, and would not be up for two or three hours more. His cavalry had just reported to him that the Cerro seemed to be abandoned, and that the troops formerly holding it were marching across his front through the forest. Since the main body of the enemy had been located opposite Villatte, on the Almanza creek, there seemed to be a good chance of seizing the important Barrosa position unopposed, and of striking the rear division of the Allies while it was defiling, strung out helplessly in a wood road, across the front of the advancing French. The orders given by the Marshal sent his cavalry regiment (three squadrons of the 1st Dragoons) to turn the heights by their south-eastern flank, and seize the coast track, while Ruffin ascended the Cerro by its gently sloping northern front, and Leval struck at the troops known to be in the wood. The French, being quite fresh, came on at a great pace; the Marshal had explained to his subordinates that haste was everything. They were clearly visible to the rearguard left on the heights, partly visible to La Peña, who could see their flank up the trough of the Almanza creek, but wholly invisible to Graham and his troops in the wood.
