The Battle of Orthez was fought on 27 February 1814 in the southwest of France near the end of the Peninsular War. An army of British, Spanish and Portuguese troops under Field Marshal Lord Wellington attacked a French army led by Marshal Jean-de-Dieu Soult in southern France. The outnumbered French repelled several Allied assaults on their right flank, but their center and left flank were overcome and Soult was compelled to retreat. At first the withdrawal was conducted in good order, but it eventually ended in a scramble for safety and many French soldiers were taken prisoner.
In mid-February, Wellington's army broke out of its small area of conquered territory near Bayonne. Moving east, the Allies drove the French back from several river lines. After a pause in the campaign, the westernmost Allied corps surrounded and isolated Bayonne. Resuming their eastward drive, the remaining two Allied corps pushed Soult's army back to Orthez where the French marshal offered battle. In subsequent operations, Soult decided to abandon the large western port of Bordeaux and fall back east toward Toulouse. The next action was the Battle of Toulouse.
Background
Armies
The Battle of the Nive ended on 13 December 1813 when Wellington's army repulsed the last of Soult's assaults. This ended the fighting for the year. Soult had found the Allied army divided by the Nive River but failed to inflict a damaging defeat. The French then pulled back within Bayonne's defenses and entered winter quarters. Heavy rains brought operations to a standstill for the next two months. After the Battle of Nivelle on 10 November 1813, Wellington's Spanish troops had gone out of control in seized French villages. Horrified at the idea of provoking a guerilla war by French civilians, the British commander imposed a vigorous discipline on his British and Portuguese soldiers and sent most of his Spanish troops home. Since his men were paid and fed by the British government, Pablo Morillo's Spanish division remained with the army. Wellington's policy paid dividends; his soldiers soon found that guarding the roads in his army's rear areas was no longer required.
In January 1814, Soult sent reinforcements to Napoleon. Transferred to the Campaign in Northeast France were the 7th and 9th infantry divisions and Anne-François-Charles Trelliard's dragoons. Altogether, this totaled 11,015 foot soldiers under Jean François Leval and Pierre François Xavier Boyer and 3,420 horsemen in the brigades of Pierre Ismert, François Léon Ormancey and Louis Ernest Joseph Sparre. This left Soult with the 1st Division under Maximilien Sébastien Foy (4,600 men), 2nd Division led by Jean Barthélemy Darmagnac (5,500 men), 3rd Division commanded by Louis Jean Nicolas Abbé (5,300), 4th Division directed by Eloi Charlemagne Taupin (5,600 men), 5th Division commanded by Jean-Pierre Maransin (5,000 men), 6th Division under Eugène-Casimir Villatte (5,200 men), 8th Division led by Jean Isidore Harispe (6,600 men) and Cavalry Division under Pierre Benoît Soult (3,800 men). Marshal Soult also commanded 7,300 gunners, engineers and wagon drivers plus the garrisons of Bayonne (8,800 men) and Saint-Jean-Pied-de-Port (2,400 men).
Wellington's army consisted of the 1st Division under Kenneth Howard (6,898 men), 2nd Division commanded by William Stewart (7,780 men), 3rd Division led by Thomas Picton (6,626 men), 4th Division directed by Lowry Cole (5,952 men), 5th Division under Andrew Hay (4,553 men), 6th Division commanded by Henry Clinton (5,571 men), 7th Division led by George Townshend Walker (5,643 men), Light Division under Charles Alten (3,480 men), Portuguese Division directed by Carlos Lecor (4,465 men) and Spanish Division led by Morillo (4,924 men). Stapleton Cotton commanded three British light cavalry brigades under Henry Fane (765 men), Hussey Vivian (989 men) and Edward Somerset (1,619 men). There were also three independent infantry brigades, 1,816 British led by Matthew Whitworth-Aylmer, 2,185 Portuguese under John Wilson and 1,614 Portuguese directed by Thomas Bradford.
Operations
Wellington planned to use the greater part of his army to drive the bulk of Soult's army well to the east, away from Bayonne. Once the French army was pressed sufficiently far to the east, a strong Allied corps would seize a bridgehead over the river Adour to the west of Bayonne and encircle that fortress. Because Soult's army was weakened by three divisions, Wellington's forces were superior enough to risk dividing them into two bodies. Soult wished to contain his opponent in a wedge of occupied French territory. Strongly garrisoned Bayonne blocked the north side of the Allied-occupied area. East of the city, three French divisions held the line of the Adour to Port-de-Lanne. The east side of the Allied-occupied area was defended by four French divisions along the river Joyeuse as far south as Hélette. Cavalry patrols formed a cordon from there to the fortress of Saint-Jean-Pied-de-Port in the Pyrenees.
On 14 February, Wellington launched his offensive toward the east. On the right flank was Rowland Hill's 20,000-man corps which included the 2nd and 3rd divisions, Lecor's Portuguese and Morillo's Spanish divisions and Fane's cavalry. Hill's main column struck toward Harispe's division at Hélette. Picton moved on the left flank against Villatte's division at Bonloc and Morillo took his men through the foothills on the right flank. On 15 February, Hill's column defeated Harispe's division in the Battle of Garris and forced the French to abandon Saint-Palais and the line of the river Bidouze.
The 25,400-strong Allied left flank corps under William Beresford began its advance on 16 February, aiming for the village of Bidache. Beresford's corps was made up of the 4th, 6th, 7th and Light divisions as well as Somerset's and Vivian's cavalry. Altogether, Wellington had 42,000 foot soldiers and 3,000 horsemen marching to the east. Reacting to the Allied pressure, Soult joined two of the three divisions north of the Adour to the four divisions farther east. This action created a field army of 32,000 infantry and 3,800 cavalry. The French divisions were directed to form a new line behind the Gave d'Oloron River, along a line from Peyrehorade to Sauveterre-de-Béarn to Navarrenx. On 17 February, Hill's corps forded the river Saison, breaching yet another French defensive line. The French marshal sent Abbé's division to help defend Bayonne, a questionable move which left his army with fewer troops to fight Wellington. By 18 February, Soult had his troops in position on the Gave d'Oloron. That day the weather broke again, causing another pause in operations.
During the lull, Wellington ordered John Hope's corps to begin the isolation of Bayonne. Since Adour is 300 yards (274 m) wide with a tidal rise of 14 feet (4.3 m) below Bayonne, Soult never suspected the Allies would cross there and did not guard the north bank. Facing an Allied offensive that required crossing rivers, the French marshal believed that his foes would not have enough boats or pontoons to bridge the river. Hope sent eight companies from the 1st Division across the Adour on 23 February to form a bridgehead. That evening Congreve rockets dispersed two French battalions that were sent to investigate the incursion. The next day 34 vessels of 30 to 50 tons sailed into the mouth of the Adour, were moored together and a roadway was built across their decks. By the evening of 26 February, Hope marched 15,000 of his 31,000 men over the bridge onto the north bank. After sustaining 400 casualties in a successful bid to capture the Sainte-Étienne suburb, the Allies encircled Bayonne on 27 February. French casualties were only 200 in the action. The siege was pursued in a lackadaisical fashion until 14 April when the bloody and pointless Battle of Bayonne erupted.
On 24 February, Wellington launched a new offensive against Soult's army. For this operation, Hill was reinforced by the 6th and light divisions. Beresford with two divisions mounted a feint attack against the northern end of the French line. Picton was supposed to demonstrate opposite Sauveterre but he exceeded his orders. He found an apparently unguarded ford about 1,000 yards (914 m) from the bridge and pushed four light companies from John Keane's brigade across. After a steep climb, they reached high ground only to be overpowered by a battalion of the 119th Line Infantry from Villatte's division. In their flight down the slope and across the river, about 30 men were captured and a few drowned; about 80 of the 250 men became casualties. Hill built a boat bridge and thrust 20,000 troops across the Gave d'Oloron at Viellenave-de-Navarrenx between Sauveterre and Navarrenx. With his latest position compromised, Soult ordered a retreat to Orthez on the Gave de Pau River.
Battle
Plans and forces
Since Wellington was anxious not to bring on an engagement, he tried to flank Soult out of position. He sent Beresford to cross the Gave de Pau downstream at Lahontan and circle around Soult's right flank. At the same time, Hill's corps moved directly toward Orthez. By 25 February, Soult had massed his army at Orthez and courted battle with the Allies. The French marshal counted 33,000 foot soldiers, 2,000 horsemen, 1,500 gunners and sappers, supported by 48 field guns. Wellington could bring 38,000 infantry, 3,300 cavalry, 1,500 gunners and sappers, supported by 54 artillery pieces against the French. Five battalions were absent: 1/43rd Foot and 1/95th Rifles from the Light Division, 2nd Provisional from 4th Division, 79th Foot from 6th Division and 51st Foot from 7th Division. Confronted with Soult in a fighting mood, the British commander planned to send Beresford to break Soult's right flank while Picton and three divisions kept the French center busy. Meanwhile, Hill's corps was to attack Orthez, get across the Gave de Pau and envelop the French left flank. With luck, Soult would be crushed between Beresford and Hill.
At Orthez, the Gave de Pau runs approximately from southeast to northwest. Since Beresford was already on the same side of the Gave de Pau, the river only protected Soult's position to the east of Orthez. However, there is an east–west ridge on the north side of Orthez that ends at the village of Saint-Boès on the west. The ridge is about 500 feet (152 m) high and the road from Orthez to Dax runs along its crest. However, the knolls at the Lafaurie, Luc and Plassotte Farms were even higher, the last-named rose 595 feet (181 m) above Saint-Boès. The three high points were crowned with French artillery. Aside from Saint-Boès, the ridge can be approached from the west by two spurs with marshy ground in between.
Soult posted four and one-half divisions along this ridge, one division in Orthez and one division in reserve. Unlike the other divisions which had two brigades, Harispe's division contained three brigades. His third brigade under Marie Auguste Paris was detached to the right flank. Going from right to left, the ridge was held by the divisions of Taupin, Claude Pierre Rouget, Darmagnac and Foy. Rouget was in temporary command of Maransin's division. Harispe's remaining two brigades held Orthez while Villatte's division was in reserve north of Orthez. Honoré Charles Reille commanded Taupin, Rouget and Paris on the right flank, Jean Baptiste Drouet, comte d'Erlon led Darmagnac and Foy in the center and Bertrand Clausel supervised Harispe and Villatte on the left flank. Pierre Soult's cavalry was scattered. The 2nd Hussars and the 22nd Chasseurs-à-Cheval were near Pau and out of the battle. The 13th, 15th and 21st chasseurs-à-cheval were detached to Harispe, D'Erlon and Reille, respectively, while the 5th and 10th chasseurs-à-cheval were in reserve.
Wellington planned to send Cole's 4th Division supported by Walker's 7th Division to attack the western end of the ridge under the direction of Beresford. Picton would lead his own 3rd Division and Clinton's 6th Division in pinning the French center. Hill's corps was ordered to feint against Orthez with a Portuguese brigade and hold his two divisions ready to cross the Gave de Pau to the east of Orthez. Alten's Light Division was placed under cover behind an old Roman camp where Wellington set up his headquarters. The camp was located between Beresford's and Picton's columns. The 44,402-strong Allied army included 3,373 light cavalry in three brigades and 1,512 gunners, engineers and wagon drivers. Morillo's division was besieging Navarrenx while five British battalions were not present in the field while being issued fresh uniforms. The 1st Hussars King's German Legion (KGL) Regiment was part of the Allied cavalry.
