The Battle of Molins de Rei or Battle of Molins de Rey or Battle of Molins del Rey (21 December 1808) saw an Imperial French corps led by Laurent Gouvion Saint-Cyr attack a Spanish army temporarily led by Theodor von Reding and the Conde de Caldagues because its commander Juan Miguel de Vives y Feliu was absent. Saint-Cyr outmaneuvered his opponents, distracting them with a false attack in front while sending the bulk of his force across Llobregat River in a turning movement around the Spanish right flank. The Spanish defensive lines crumbled and the French captured 1,200 soldiers, all the Spanish artillery and Caldagues himself. The Peninsular War engagement was fought near Molins de Rei, located west of Barcelona, Catalonia, Spain.
The Dos de Mayo Uprising caught the Imperial French occupation forces in Spain off guard. By the end of August 1808, the Franco-Italian garrison of Barcelona found itself isolated and in danger of capture. Emperor Napoleon soon assembled a substantial army, entrusted it to Saint-Cyr, and directed his general to relieve Barcelona. After a risky campaign, Saint-Cyr defeated a Spanish force at Cardadeu and reached Barcelona. Finding his opponents holding a strong position behind the Llobregat, Saint-Cyr marched out of Barcelona and resolved to drive them away.
Background The Corunna campaign started with the Battle of Cardedeu. Strategic situation After the Treaties of Tilsit in 1807, Emperor Napoleon began to exhibit such signs of megalomania that his brilliant diplomat Charles Maurice de Talleyrand-Périgord resigned as foreign minister. Undeterred, Napoleon got King Charles IV of Spain and his son Prince Ferdinand into his custody and then tricked both into abdicating. Then he announced that his brother Joseph Bonaparte would reign as the Spanish king. Meanwhile, on various pretexts, Napoleon moved significant bodies of Imperial French troops into Spain. In February 1808, these soldiers seized Barcelona and many border fortresses. On 2 May 1808, street riots in Madrid were put down with extreme measures by Marshal Joachim Murat and 20,000 Imperial troops. Very soon, the Spanish people rose in rebellion against the French occupation forces.
Guillaume Philibert Duhesme commanded the Corps of Observation of the Eastern Pyrenees which numbered 12,714 men. The 1st Division under Joseph Chabran was made up of one Swiss and seven French battalions and counted 6,045 soldiers. The 2nd Division under Teodoro Lechi had 4,596 troops in four Italian and two Neapolitan battalions. The cavalry brigade led by Bertrand Bessières numbered 825 troopers in two French provisional regiments, while the cavalry brigade commanded by François Xavier de Schwarz counted 892 Italian and Neapolitan horsemen. There were also 356 artillerymen and wagon drivers. Napoleon expected Duhesme to help capture Valencia and Lleida as well as hold Barcelona. These instructions proved to be hopelessly optimistic, given Duhesme's limited numbers and the intensity of the spreading revolt.
The Battles of El Bruch were two unsuccessful attempts to clear the El Bruc pass, first by Schwarz and then by Chabran. Taking half his corps, Duhesme tried to clear the road to France, but in the Battle of Gerona his troops were unable to storm the city. Napoleon realized that Duhesme needed help, so he scraped together 8,000 second-class French soldiers into a new division and assigned it to Honoré Charles Reille. First, Reille marched to the relief of the Sant Ferran Castle at Figueres, then he tried to capture the port of Roses (Rosas) but failed. In late July, Reille and Duhesme converged on Girona from north and south and began the Second Siege of Gerona. This operation progressed so slowly that Conde de Caldagues attacked the siege lines and forced the French to withdraw. Reille retired to Figueres with little trouble, but the miquelets, a Catalan militia, harassed Duhesme's soldiers unmercifully. Duhesme had to abandon his artillery and wagon train before his troops escaped to Barcelona on 20 August 1808.
Operations When Napoleon finally understood the scope of the problem in Catalonia, he made some significant changes. Already on 17 August 1808, Napoleon appointed Laurent Gouvion Saint-Cyr to be his new commander in Catalonia. Saint-Cyr was reinforced by 18,000 men from the garrison of Italy, though it would be weeks before they could arrive. Unlike Reille's motley soldiers, these included crack troops in the French division of Joseph Souham and the Italian division of Domenico Pino. There was also a small Franco-Italian division under Louis François Jean Chabot, an Italian cavalry brigade led by Jacques Fontane, and the French 24th Dragoon Regiment.
Meanwhile, 10,000 Spanish regulars were idle in the Balearic Islands because their commander Juan Miguel de Vives y Feliu was afraid that his new British allies planned to seize the islands. After the soldiers threatened to mutiny, Vives finally allowed Marquis del Palacio to sail to the mainland with 5,000 men. These troops landed in Catalonia by 23 July. The local authorities appointed Del Palacio the new Captain General of Catalonia and he opened a blockade of Barcelona. About 10,000 Spanish troops under Theodor von Reding from the Province of Granada were approaching Catalonia. A division from the Province of Aragon under Luis Rebolledo de Palafox y Melci, 1st marqués de Lazán reached Lleida. Palacio remained so inert during the summer and fall that he was replaced as Captain General by Vives on 28 October. By this time the Spanish numbered 20,000 infantry and 1,000 cavalry. Vives tightened the blockade of Barcelona and finally drove the garrison within its walls on 26 November. Other than that, Vives proved to be as slow and unenterprising as Palacio.
Saint-Cyr opened the Siege of Roses on 7 November 1808 and Roses surrendered on 5 December. This removed a potential threat to the French communications. Saint-Cyr arrived before the fortress of Girona with 17,000 troops in the second week of December. He hoped to lure the Spanish garrison outside the walls, but this tactic did not work. The commander at Girona, Mariano Álvarez de Castro and Lazán refused to risk their 8,000 soldiers in the open field against Saint-Cyr's much superior force.
The French commander knew that besieging Girona would take too long, so he sent away his artillery and his wagon trains and boldly slipped past Girona, leaving Reille's division behind. Vives assumed that the French would be stalled in front of Girona. When he found that Saint-Cyr was marching through the hills, he responded by sending a division under Reding to block the French. Vives finally woke up and brought an additional brigade, though he had 24,000 troops available. Saint-Cyr completely outfoxed his opponents and arrived near the village of Cardadeu to find Vives and Reding facing him with only 9,100 soldiers and seven cannons. In the Battle of Cardadeu on 16 December Saint-Cyr utilized massive attack columns to smash through the Spanish lines. The French inflicted 2,500 casualties on their adversaries while suffering a loss of only 600. Vives became separated from his army. He fled to the coast where he was picked up by and shipped to Tarragona.
Battle Preparations
On 16 December, Conde de Caldagues drove off a strong sortie that was mounted by the defenders of Barcelona, but that evening he heard about the Spanish defeat at Cardedeu. Accordingly, Caldagues withdrew the blockading force behind the Llobregat River to positions from Molins de Rei on the north and Sant Boi de Llobregat on the south. During the hasty retreat, Caldagues abandoned a large food depot at Sarrià to the Imperial French. On the morning of 17 December, Saint-Cyr led his army of relief into Barcelona. To his annoyance, no soldiers from the blockaded garrison were sent out to greet his victorious soldiers. When the egotistical Duhesme finally appeared, he remarked to Saint-Cyr that his forces were not in danger and would have been able to hold out for another six weeks. Not to be outdone, the prickly Saint-Cyr produced a copy of one of Duhesme's dispatches to Marshal Louis-Alexandre Berthier stating that his garrison was in dire straits and begging for its relief. Duhesme withdrew to sulk in silence.
After being deserted by about 1,000 of his miquelets, Caldagues counted 11,000 troops. These were soon joined by Reding who brought the remnants of the force beaten at Cardedeu, 3,000–4,000 men. The lines along the Llobregat included the field fortifications built for the right wing of the blockade and they were only about from the Barcelona suburbs. The defenses were strong and mounted heavy guns, but were too long for an army of 15,000 soldiers. The Llobregat was fordable at many points and if the French assault came at one point it was likely to succeed. In the absence of Vives, the second-in-command Reding took control of the Spanish forces. He and the third-in-command Caldagues knew the Spanish position was weak but they were in a dilemma.
Reding and Caldagues wanted to retreat west into the very strong position at Ordal, where they planned to construct an entrenched camp. However, a withdrawal to Ordal would open the Barcelona–Lleida highway to the French. It would also allow the French to gather up the crops in the plains. Looking for some direction, Reding sent a message to Vives who was at Sitges. Vives failed to assume responsibility, leaving it to Reding to decide whether to defend or retreat. Vives' reply arrived on the night of 20–21 December. In order to demonstrate his courage in the eyes of the Catalans, Reding determined to fight.
Imperial forces
Saint-Cyr led four divisions out of the city on the windy and cold morning of 21 December 1808, leaving Duhesme to hold Barcelona with Lechi's Italian division. The Imperial forces included the divisions of Chabran, Souham, Pino, and Chabot. Chabran's division was part of Duhesme's corps which had been blockaded in Barcelona. Chabran's troops were French veterans plus one battalion of Swiss. Souham's French and Pino's Italian divisions were made up of crack troops. Chabot's division consisted of one battalion of French soldiers and two of Neapolitans. The Neapolitans were widely regarded as the worst troops in Europe. Saint-Cyr's force also included Fontane's cavalry brigade, consisting of the Italian Royal Horse Chasseurs and the 7th Italian Dragoons.
Action
Saint-Cyr planned for Chabran's 4,000-man division to mount a diversionary attack on Molins de Rey bridge. While the Spanish generals were distracted, 14,000 troops in the divisions of Souham, Pino, and Chabot would cross the lower fords of the Llobregat and march against the Spanish right flank. At 5:00 am, Chabran began his feint against the Spanish left flank. Reding was fooled and reinforced his left by drawing some troops from his right flank. At 6:00 am the real Imperial assault began when Saint-Cyr ordered his other three divisions to advance.
Souham's division crossed at the ford of Sant Joan Despí. The Spanish troops of the center began to march downhill to oppose Souham, but they flinched and did not push their attack. The divisions of Pino and Chabot crossed farther south at San Feliu against weak opposition. The Imperial French soon cracked the overextended Spanish line in several locations. Chabot's small division on the extreme left swept completely around the Spanish right flank. As Chabot's troops moved deeper into the Spanish rear, the troops fighting against Pino and Souham were compelled to yield good defensive terrain and fall back. The Imperial advance rolled up the broken Spanish left and center, thrusting them toward the north in a confused mass.
