Napoleon's invasion of Spain had started with the
Battle of Zornoza.
Initial operations Emperor Napoleon I plotted to replace the royal family of the
Kingdom of Spain. Pursuant to his design, he ordered several key points, including
Barcelona, to be seized in February 1808. On 29 February,
General of Division Giuseppe Lechi's Imperial French troops were marching through Barcelona, ostensibly to help fight Portugal. Lechi staged a military review, but it was a cover for gaining control of the citadel. As the soldiers marched past the main gate of the fortress, they suddenly turned left and rushed inside. Without spilling a drop of blood, the Imperial troops herded the baffled Spanish garrison out of the fortifications and occupied the place. Among other key points, the French also grabbed
San Sebastián,
Pamplona and
Figueres. On 2 May 1808, the infuriated Spanish people rose in rebellion against their French occupiers. A 12,710-man Franco-Italian corps commanded by General of Division
Guillaume Philibert Duhesme guarded Barcelona in June 1808. General of Division
Joseph Chabran's 1st Division consisted of 6,050 soldiers in eight battalions, while Lechi's 2nd Division had 4,600 men in six battalions.
Generals of Brigade Bertrand Bessières and
François Xavier de Schwarz led 1,700 cavalrymen in nine squadrons. There were also 360 artillerists. The French authorities in
Madrid confidently expected that Duhesme's corps would quickly stamp out the rebellion in
Catalonia, but they grossly underestimated its seriousness. The
miquelets, the Catalan militia, turned out in large numbers to harass their enemies. In June, Schwarz and Chabran were beaten at the
Battles of the Bruch and Duhesme was turned back at the
Battle of Girona. Finally awakening to reality, Napoleon ordered General of Division
Honoré Charles Reille and a division of reinforcements to Duhesme's assistance. The troops were of low quality and scattered throughout southern France, but Reille quickly cobbled together a fraction of this force and successfully relieved the French garrison of Figueres. Joined by more of his division, he next marched on the port of
Roses.
First attack on Roses Reille commanded 4,000 men and two cannons. These troops included two battalions of the 113th Line Infantry Regiment, 560 men of the
Pyrenées Orientales Garde Nationale, two companies of the 2nd Swiss Infantry Regiment, 700 gendarmes and department reserves, and various march battalions and conscript drafts. Roses was held by about 800 men of the Fija de Roses regiment and 400
miquelets, the Catalan militia, with 5,000 more miquelets under Colonel
Juan Clarós in the nearby hills. The defenders were given a boost when the British warship , under Captain Robert Otway, appeared off the port and landed her marines to help. Reille launched an attack on 11 July 1808, but his troops were driven off with 200 casualties. Spanish losses were light. Thwarted at Roses, Reille moved in the direction of Girona. When he reached there, he joined with Duhesme to initiate the
Siege of Girona. Meanwhile, 5,000 Spanish regular troops from the
Balearic Islands commanded by the Marquis Del Palacio landed at
Tarragona. Appointed
Captain General of Catalonia, Del Palacio joined his regulars with a large mass of Catalan irregulars to start a
blockade of Barcelona, on 1 August 1808. Lechi's 3,500-man Italo-Swiss garrison defended the city. Among a large population that threatened to revolt at any moment, Lechi began sending alarming reports to Duhesme after being compelled to abandon his outposts, such as the castle of Mongat. Even though Duhesme mustered 13,000 soldiers for the siege operation, it ended in failure after starting on 24 July and dragging on until 16 August. When his siege lines were attacked from the rear by a force under the
Conde de Caldagues, Duhesme gave up and ordered a withdrawal. He buried his heavy siege cannons, burned his supplies, and headed back to Barcelona while Reille fell back to Figueres. While marching along the coast road Duhesme's marching columns were bombarded by the British
frigate commanded by Captain
Thomas Cochrane. Faced with this threat and the miquelets' road demolitions, the French veered away from the vulnerable coast highway. After throwing eight field guns into the sea and leaving behind their baggage train, Duhesme's men struck out into the mountains and finally reached Barcelona on 20 August. One source described the Imperial column as "a starving, demoralized mob" by the time it arrived. In October, Napoleon appointed General of Division
Laurent Gouvion Saint-Cyr and a new corps to relieve Barcelona.
Opposing forces The newly activated
VII Corps was made up of six infantry divisions and three cavalry brigades. Chabran's 1st Division, Lechi's 2nd Division, and the mounted brigades of Bessières and Schwarz were cooped up inside Barcelona with Duhesme. With Gouvion Saint-Cyr were Reille's 3rd Division of 12 battalions, General of Division
Joseph Souham's 4th Division of 10 battalions, General of Division
Domenico Pino's 5th Division of 13 battalions,
Louis François Jean Chabot's 6th Division of three battalions, and General of Brigade Jacques Fontane's cavalry brigade of one dragoon and one light cavalry regiment. There was also one unattached dragoon regiment. Including Duhesme's stranded troops, the VII Corps counted 42,380 soldiers. To build up this force, Napoleon had to shift troops from Italy to Spain. On 28 October the siege artillery finally arrived at the frontier. Bottled up in Barcelona, Duhesme's 10,000 remaining troops were in a vulnerable situation, but Del Palacio did not press operations with vigor. Instead, he ordered Caldagues to hold a line long with 2,000 regulars and 4,000 to 5,000 miquelets while remaining at Tarragona, far from the action. Duhesme periodically sent out strong columns to strip the countryside of food and supplies for his soldiers. On 12 October, a column was roughly handled and the excursions finally stopped. Finally, on 28 October, the Catalan Junta replaced Del Palacio with Captain General
Juan Miguel de Vives y Feliu. The new commander was a veteran of the
War of the Pyrenees, having commanded the Spanish left wing at the
Battle of Boulou in 1794. De Vives attacked the French outpost line on 6 November. After this, the Spanish remained quiescent until 26 November when de Vives' offensive forced the French to take refuge behind the walls of Barcelona. In the fall of 1808, the 20,031 men of the Army of Catalonia were organized into a vanguard, four divisions, and a reserve. Brigadier General
Mariano Álvarez de Castro led the Vanguard with 5,500 infantry in 10 battalions and 100 cavalry in one squadron. Mariscal de Campo Caldagues commanded the 1st Division with 4,528 foot soldiers in seven battalions, 400 horsemen in four squadrons, and six guns served by 70 artillerists. Mariscal de Campo Gregorio Laguna directed the 2nd Division with 2,076 soldiers in five battalions, 200 cavalry in two squadrons, and seven artillery pieces served by 84 gunners. Colonel Gaspar Gomez de la Serna led the 3rd Division with 2,458 men in five battalions and Colonel
Francisco Milans del Bosch commanded the 4th Division with 3,710 troops in four battalions. There was also a reserve of 777 infantry, 80 cavalry, and 48 artillerists serving four guns. ==Siege==
