In the Battle of Fuentes de Oñoro (3–6 May 1811), the British-Portuguese Army under Viscount Wellington checked an attempt by the French Army of Portugal under Marshal André Masséna to relieve the besieged city of Almeida.


In 1810, Masséna had followed the British-Portuguese back to Lisbon before arriving at the Lines of Torres Vedras. He was determined against storming this extensive double line of interlocking fortifications. After starving outside Lisbon through a miserable winter, the French withdrew to the Spanish border with the British-Portuguese army in pursuit.

After Portugal was secured, Wellington set about re-taking the fortified frontier cities of Almeida, Badajoz and Ciudad Rodrigo. Whilst Wellington besieged Almeida, Masséna reformed his battered army and marched to relieve the French garrison in the city. Wellington chose to check the relief attempt at the small village of Fuentes de Oñoro. Wellington left his line of retreat exposed to cover all routes to Almeida: he felt this risk was justified because the French would not have more than a few days supplies whereas he had more than that. The British and Portuguese army had 34,000 infantry, 1,850 cavalry, and 48 guns. The French had 42,000 infantry, 4,500 cavalry and 38 guns.


The French Army of Portugal

Masséna's army was organised into four corps and a cavalry reserve. Louis Henri Loison's VI Corps had three divisions, led by Jean Gabriel Marchand, Julien Augustin Joseph Mermet, and Claude François Ferey. In Jean Andoche Junot's VIII Corps, only Jean Baptiste Solignac's division was present. Jean-Baptiste Drouet's IX Corps included the divisions of Nicolas François Conroux and Michel Marie Claparède. Louis Pierre, Count Montbrun headed the cavalry reserve. Jean Reynier's II Corps hovered off to the northeast threatening Almeida with its two divisions under Pierre Hugues Victoire Merle and Étienne Heudelet de Bierre.

An 800-men cavalry force, comprising squadrons of the élite Imperial Guard Grenadiers à Cheval and Empress Dragoons was also present at the battle under the command of Marshal Jean-Baptiste Bessières. The reinforcements that Bessières brought were almost symbolic, despite the fact Masséna had requested that he bring the entirety of his Army Corps into battle.[12]

The British-Portuguese army

Wellington commanded six infantry divisions, Charles Ashworth's independent Portuguese brigade and three cavalry brigades. Brent Spencer commanded the 1st Division, Thomas Picton the 3rd, William Houston the 7th and Robert Craufurd the Light Division. Stapleton Cotton commanded John Slade's and Frederick von Arentschildt's brigades of cavalry. Edward Howorth supervised four British (Ross RHA, Bull RHA, Lawson, Thompson) and four Portuguese (Arentschildt (2), Da Cunha, Rozierres) 6-gun batteries. William Erskine (5th Division), Alexander Campbell (6th Division) and 300 Portuguese cavalry under Count Barbacena were detached, facing the French II Corps.

Map of the battle

On 3 May, Masséna launched a frontal assault against the British-Portuguese pickets holding the barricaded village, while bombarding the British-Portuguese on the heights east of the village with heavy artillery. The fight in the center of the villiage lasted all that day, with French soldiers of Ferey's and Marchand's divisions clashing with the British redcoats of the 1st and 3rd Divisions.

At first, the British-Portuguese were driven back under immense pressure, but a charge that included men of the 71st Highland Light Infantry reclaimed the streets and buildings lost earlier in the day. As the sun sank, the French withdrew and the village remained in British hands, with the former suffering 650 casualties against only 250 for the British.

4 May saw little combat. Both sides recovered from the ferocity of the previous day of fighting and reconsidered their options and battle plans. A French reconnaissance revealed that Wellington's right flank was weakly held by a unit of partisans near the hamlet of Poco Velho.

Action began again at dawn on 5 May. Wellington had left the 7th Division exposed on his right flank. Masséna launched a heavy attack on the weak British-Portuguese flank, led by Montbrun's dragoons and supported by the infantry divisions of Marchand, Mermet and Solignac. Right away, two 7th Division battalions were roughed up by French light cavalry. This compelled Wellington to send reinforcements to save the 7th Division from annihilation. This was only achieved by the efforts of the Light Division and the British and King's German Legion[13] cavalry.

On the threatened British-Portuguese right flank, the elite Light Division, well supported by cavalry and artillery, made a textbook fighting withdrawal. For trifling casualties, they covered the retreat of the 7th Division and fell back into a stronger position selected by Wellington. During the retreat, whenever French artillery ventured too close, the British cavalry charged or feinted a charge. This allowed the infantry time to retreat out of range. If the French horsemen pressed the outnumbered British cavalry back, the British-Portuguese infantry formed square and their volleys drove off the French. Montbrun then requested help from the Imperial Guard cavalry, which were present but had not yet been committed to battle.

Time was at the essence and Masséna at once sent one of his aides-de-camp, Charles Oudinot, the son of Marshal Duke of Reggio, with orders to bring forward the Guard cavalry. The young Oudinot hastily set off and Masséna was impatiently checking his watch, counting every minute, pressed to commit this cavalry to what he saw as being a decisive action of the battle. Much to the general staff's stupefaction, Oudinot was soon seen returning without any cavalry following him. As soon as he saw him, Masséna furiously shouted from afar: "Where is the cavalry of the Guard?". The sweaty, dust-filled Oudinot needed a moment to catch his breath after his exhausting gallop but then explained that he was not able to fetch it. Oudinot had encountered the Guard cavalry deputy commander, General Louis Lepic, who sharply refused to commit his men, saying that he only recognised the Duke of Istria (Bessières) as commander and that without explicit orders from its commander, the Guard Horse Grenadiers and Dragoons would not draw their swords. In a staggering display of treachery, Bessières was absent from the field of battle, needlessly inspecting a series of ditches where the French army had passed a few days before. Unable to find the commander of the Guard in time, Masséna was forced to admit that the opportunity was lost.[12]

Two incidents spoiled this otherwise fine accomplishment for the British-Portuguese. One occurred when a British 14th Light Dragoon squadron pressed home a frontal attack on a French artillery battery and was mauled. In the second case, French cavalry caught some companies of the 3rd Foot Guards in skirmish order and inflicted 100 casualties.

Masséna, however, was still aimed primarily at securing Fuentes de Oñoro. He sent forward massed columns of infantry from Ferey's division. The village, filled with low stone walls, provided excellent cover for the British line infantry and skirmishers, while the French were severely restricted in the little streets. At first, the French had some success, wiping out two companies of the 79th Highland Regiment and killing the regiment's commander, Lieut-Colonel Philips Cameron. But a counterattack chased Ferey's men out of the town.

Drouet launched a second attack on the town. This time it was led by three battalions of converged grenadiers from IX Corps. With their old-fashioned bearskin hats, the grenadiers were mistaken for the Imperial Guard. Again, the British fell back. Drouet threw in about half of the battalions from both Conroux and Claparède's divisions, seizing almost the entire town.

In response, Wellington counterattacked with units from the 1st and 3rd Divisions, plus the Portuguese 6th Caçadores. Led by the 88th Connaught Rangers Foot, this effort broke Drouet's attack and the tide began to turn. Low on ammunition, the French had to resort to the bayonet in a futile attempt to drive the British back. One party of 100 grenadiers was trapped in a tight spot and slaughtered to a man. Facing murderous volleys, the French halted and turned, being shot at as they withdrew, leaving their casualties behind. By sunset, French morale had plummeted and many companies were down to 40% strength.

The French artillery tried to bombard the new British line into submission, but they were outgunned by Wellington's cannon. Finally, with their artillery ammunition dangerously low, the French attacks came to an end. Wellington's men entrenched during the evening. After spending the next three days parading before the British position, Masséna gave up the attempt and retreated to Ciudad Rodrigo. He was furious because Bessières refused to fetch ammunition from the citadel.[2]


Wellington had repelled the Army of Portugal, inflicting a great number of casualties, and was able to continue his blockade of Almeida. (The numbers of losses vary according to different sources, from 2,200[8][14] to 3,500[15] French for the loss of 1,500 Allies, while another historian stated there were 2,800 French and 1,800 Allied losses.[11]) However, he acknowledged how dangerous the situation had been, saying later, "If Boney had been there, we should have been beat."[1] Indeed, Russian historian Oleg Sokolov noted that Wellington had committed a serious strategic error by following the French into northern Portugal, and that this decision could have had grievous consequences for the Anglo-Portuguese. Sokolov adds that, despite the various setbacks that he encountered before and during the battle, Masséna was still able to check Wellington's position at Fuentes de Onoro.[12] Wellington himself did not mark the battle as a victory; he also considered that he had unnecessarily extended his line, putting the 7th and Light Divisions in danger.

Two nights after Masséna's withdrawal, Antoine Brenier's 1,400-man French garrison of Almeida slipped through the British lines during the night. About 360 of the French were captured, but the rest got away when their British pursuers ran into a French ambush. This fiasco was blamed on Erskine and others. An infuriated Wellington wrote, "I have never been so much distressed by any military event as by the escape of even a man of them."[16]

On reaching Ciudad Rodrigo, Masséna was recalled to Paris by a furious Napoleon to explain his actions (although Napoleon had issued the order to return prior to the battle). He was replaced by Marshal Auguste Marmont. Masséna set off for France with a vast sum of gold, looted from Portugal and Spain. The defeated French marshal complained that Wellington "had not left him one black hair on his body—he had turned grey all over."[17]

Interestingly, this battle also included a notable friendly fire incident. During the proceedings, a French infantry unit mistook their allies, the Hannovarian Legion, for an English battalion and opened fire on them. The unfortunate Hannoverians retreated hastily past the village, leaving over 100 dead.[18] The reason is plain: the Hannovarian Legion wore red coats, and in the smoke and heat of battle the finer details of uniforms that might have distinguished them from British line infantry were easily overlooked.
