Having opened up the route to Cádiz, la Peña instructed Graham to move his troops forward to Bermeja. However, on Graham's strenuous objections to vacating a position that would result in both flank and rear exposed, a force of five Spanish battalions and Browne's battalion was left to hold the Barrosa Ridge. In addition, three Spanish and two
King's German Legion (KGL) squadrons of cavalry, under the command of Colonel
Samuel Whittingham, were sent to flank this rearguard force on the coast track. Graham's division then moved north as ordered—instead of descending from the heights on the coast road, they followed a path through a pine wood to the west of the ridge. This route was shorter and more practical for
artillery, but the trees restricted visibility in all directions, meaning that they were effectively marching blind.
French attack Victor was disappointed that Villatte had failed to block the Cádiz road for longer, but he was still confident that his main force could drive the Allies into the sea. He could see that the bulk of the Spanish troops had taken station opposite Villatte and, on hearing reports that Barrosa Ridge was deserted, realised that here was an opportunity to take this commanding position. Ruffin was ordered to occupy the heights while Leval struck at Graham's troops in the woods, and three squadrons of dragoons were sent around the Cerro to take the coastal track. Victor's plan rapidly developed momentum. Ruffin's advance sufficed to send the five rearguard Spanish battalions running, leaving only Browne's battalion defending the ridge and, confronted by the French dragoons, Whittingham's cavalry decided to retire. Whittingham lent a single squadron of KGL
hussars to Browne to cover his retreat; Browne initially positioned his battalion in the ruins of a chapel at the summit but, seeing Whittingham's retreat and spotting six French battalions advancing on his position, he had little choice but to give way and seek Graham's force in the woods. Barrosa Ridge fell unopposed as Victor had intended, and Ruffin
emplaced a battery of artillery on the heights.
Graham's response Meanwhile, midway through his march to join la Peña's Spaniards, Graham received news from Spanish
guerrilleros that French soldiers had emerged from the Chiclana forest. Riding to the rear of his marching columns, he witnessed the Spanish battalions retreating from the ridge, Ruffin's division climbing its slopes, and Leval's division approaching from the east. Realizing that the Allied force was in danger of being swamped, Graham disregarded his orders and turned his division to deal with the threats to his flank and rear. He ordered
General Dilkes's brigade to retake the ridge while
Colonel Wheatley's brigade was sent to see off Leval's force to the east. Because of the time it took to deploy a full brigade into battle formation, Graham knew he needed to delay the French. He therefore ordered Browne, who had rejoined the division, to turn his single "Flankers" battalion of 536 men around and advance up the slope of the Barrosa Ridge against the 4,000 men and artillery of Ruffin's division. Colonel Barnard, who led the light battalion of Wheatley's brigade, and Colonel Bushe, leading two light companies of Portuguese
skirmishers, were ordered to attack through the woods to hold up Leval's advance.
Barrosa Ridge Advancing up the ridge they had just abandoned, Browne's battalion came under intense fire from Ruffin's emplaced infantry and artillery. Within a few salvoes, half the battalion was gone and, unable to continue, Browne's men scattered amongst the cover provided by the slope and returned fire. Despite his success, Ruffin could not descend the hill to brush away the remnants of Browne's battalion, as Dilkes's brigade had by now emerged from the wood and was forming up at the base of the slope. Dilkes, instead of following Browne's route up the slope, advanced to the right where there was more cover and ground not visible to the French. As a result, the French artillery could not be brought to bear, and Dilkes's brigade managed to get near the top of the ridge without suffering serious loss. By this time, though, its formation had become disorganised, so Ruffin deployed four battalion
columns in an attempt to sweep both Dilkes and the remaining "Flankers" back down the slope. Contrary to French expectations, the crude British
line stopped the attacking columns in their tracks, and the two forces exchanged fire. Marshal Victor, by then himself on the crest of the ridge, brought up his reserve in two battalion columns of grenadiers. These columns were, as with the previous four, subjected to intense
musket fire and were brought to a halt just metres from the British line. The first four columns had started to give ground, so Victor tried to disengage his reserves and bring them to their support. However, as the two grenadier columns attempted to move off from their stalled positions, they came under additional fire from the remnants of Browne's battalion, which had renewed its own advance. Prevented from rallying, the entire French force broke and fled to the valley below.
Leval's advance While Dilkes was moving on Ruffin's position on Barrosa Ridge, Barnard and the light companies advanced through the woods towards Leval's division. Unaware of the impending British assault, the French had taken no precautions and were advancing in two columns of march, with no forward line of
voltigeurs. The unexpected appearance of British skirmishers caused such confusion that some French regiments, thinking there were cavalry present, formed
square. These were prime targets for
shrapnel rounds fired by the ten
cannon under
Major Duncan which, having made rapid progress through the woods, arrived in time to support the skirmish line. As the situation became clearer, the French organised themselves into their customary attacking formation—the 'column of divisions'—all the time under fire from Barnard's light companies and Duncan's artillery. Finally, with the French now in their fighting columns and beginning their advance, Barnard was forced to draw back. Leval's men then encountered Bushe's companies of the 20th Portuguese, who supported the light battalion's retreat and kept the French engaged until Wheatley's brigade had formed up in line on the edge of the woods. The retreating light companies joined Wheatley's troops; Leval's division of 3,800 men was now marching on an Anglo-Portuguese line of 1,400 men supported by cannon. Although they had the advantage in numbers, the French were under the impression that they were facing a superior force. Having been mauled by Barnard's and Bushe's light companies, and now facing the rolling volleys of the main British line, the French needed time to form from column into line themselves. However, Wheatley attacked as soon as the light companies cleared the field, and only one of Leval's battalions was able to even partially redeploy. The first French column Wheatley engaged broke after a single British volley. The 8th Ligne, part of this column, suffered about 50 percent casualties and lost its
eagle. The capture of the eagle—the first to be won in battle by British forces in the Peninsular wars—cost
Ensign Keogh of the
87th his life and was finally secured by
Sergeant Patrick Masterson (or Masterman, depending on source). As Wheatley's brigade moved forward, it encountered the only French battalion, from the 54th Ligne, that had begun to form line. It took three charges to break this battalion, which eventually fled towards the right where it encountered the remainder of Leval's fleeing division.
French retreat Ruffin's and Leval's divisions fled towards the Laguna del Puerco, where Victor succeeded in halting their disorganised rout. The Marshal deployed two or three relatively unscathed battalions to cover the reorganisation of his forces and secure their retreat, but Graham had also managed to call his exhausted men to order and he brought them, with Duncan's artillery, against Victor's new position. Morale in the re-formed French ranks was fragile; when a squadron of KGL hussars rounded the Cerro and drove a squadron of French dragoons onto their infantry, the shock was too much to bear for the demoralised soldiers, who retreated in a sudden rush. Throughout the battle, la Peña steadfastly refused to support his Anglo-Portuguese allies. He learnt of the French advance at about the same time as Graham, and decided to entrench his full force on the
isthmus defending the approach to the Isla de Léon. Learning of Graham's decision to engage the two French divisions, the Spanish commander was convinced that the French would win the day and so stayed in place; Zayas repeatedly asked for leave to go to Graham's support, but le Peña denied permission each time. On hearing that the British had prevailed, la Peña further declined to pursue the retreating French, again over-riding the continued protestations of Zayas. == Aftermath ==
