Battle of Tudela The Battle of Tudela was a military conflict of the Peninsular War fought on 23 November 1808 , near Tudela , Spain . The battle resulted in the complete victory of the French and Poles under Marshal Lannes against the Spanish under General Castaños . 33 , 000 Spanish soldiers fought against 30 , 000 French and Polish soldiers but were severely defeated . The Spanish casualties were estimated to be about 4 , 000 dead and 3 , 000 prisoners while on the French side there were no more than 600 dead and wounded . This is one of the battles whose name was engraved on the Arc de Triomphe in Paris . Historical Context . The Dos de Mayo ( 2 May ) uprising in May 1808 followed by extensive uprisings throughout Spain forced the French to pull back from their occupation of Spain to the Ebro river . There was an opportunity for the Spanish to finally expel the French altogether but this was missed due to their failure to appoint a Supreme Commander leaving the individual Spanish forces to operate independently . These Spanish forces consisted of the army of General Blake on the North coast , the army of General Castaños around Tudela and the army of General Palafox around Saragossa . General Blake was active in attacking the French but his offensive near Bilbao was defeated at Zornoza on 31 October 1808 . Napolean ’ s strategy was to make a strong attack towards Burgos splitting off the army of Blake from the others and to outflank them by then swinging both north and south . It was in his interest that the Spanish maintain their exposed advanced positions . The French armies facing them were therefore ordered not to attack . So from October to 21 November 1808 Marshal Moncey ’ s 3rd Corps remained static in front of General Castaños ’ s army . The Spanish armies were however in a constant state of movement to no effect . For much of the time Castaños was ill leaving Palafox to direct operations . Palafox seems to have been indecisive on what course of action to take . The Battlefield . The battlefield was the area between Tudela and the neighbouring hills on the left . The Spanish front was deployed on the hills of Santa Barbara , Tudela , Torre Monreal , Santa Quiteria the top of Cabezoe Maya ( the hill where the retreat of San Juan de Calchetas was ) , and the villages of Urzante ( now disappeared ) , Murchante , and Cascante . Separating the Spanish and the French was the Queiles River , a tributary of the Ebro . The French advanced from the Cierzo hills that were in front of the Spanish lines towards the Spanish troops . Chronology of the battle . Preliminaries . On 21 November 1808 Castaños was around Calahorra on the Ebro between Logrono and Tudela . On this day the French 3rd Corps crossed the Ebro at Logrono and headed east towards Calahorra while at the same time Marshal Ney reached the Upper Douro Valley and headed towards Tudela . These movements threatened Castaños with entrapment between these two armies . To avoid this Castaños withdrew to Tudela . He decided to defend a line 17 kilometres long stretching west from Tudela along the Ebro river then along the Queiles River to Cascante and then to Tarazona at the foot of the Moncayo Massif . Castaños had insufficient men to hold a line of this length so he asked General O ’ Neylle , who had two divisions at Caparroso on the east bank of the Ebro , for help . As O ’ Neylle was under the command of Palafox he refused to move without an order from Palafox . This did not arrive until noon on 22 November 1808 . O ’ Neylle moved promptly to the east bank of the Ebro opposite Tudela but decided not to cross the river until the next day . By nightfall on 22 November 1808 Castaños had almost 45 , 000 soldiers in the vicinity of Tudela but very few of them actually in position . Castaños placed La Peña ’ s fourth division of 8 , 000 men , mostly Andalusians who had participated in the Battle of Bailén , at Cascante and Grimarest at the head of three divisions totaling 13 , 000 to 14 , 000 soldiers at Tarazona . Roca ’ s division was on the east bank of the Ebro plus the two divisions from Aragon of O ’ Neylle and Saint Marcq . Most of the fighting in the battle of Tudela would involve only the three divisions of Roca , O ’ Neylle , and St . Marcq – totaling about 23 , 000 infantry . For the French only the 3rd Corps was involved in the Battle of Tudela . Prior to 22 November 1808 this force had been commanded by Marshal Moncey however Napolean transferred command to Marshal Lannes when the advance began . This Corps was just under 34 , 000 men consisting of four infantry divisions and three cavalry regiments . To this was added Lagrange ’ s infantry division and Colbert ’ s cavalry from Ney ’ s force . On the night of 22 November the French Army camped at Alfaro – 17 kilometres up the Ebro from Tudela . The Battle 23 November 1808 . On the morning of 23 November 1808 Lagrange ’ s infantry and two cavalry brigades were sent towards Cascante . The rest of the force was sent along the Ebro towards Tudela . At this time O ’ Neylle was trying to get his three divisions across the Ebro . Roca ’ s was across first and reached its position on the right of the Spanish line just as the French attacked . St . Marcq ’ s division was second across and also took up position before the attack . By the time O ’ Neylle ’ s own division was crossing it had to fight French skirmishers who were at the top of the Cabezo Malla ridge . The initial French attack was carried out in a piecemeal fashion by the vanguard when it was realised that the Spanish were not in position . Although this attack was repelled it showed the weakness of the Spanish positions – especially the 5 kilometre gap to La Peña ’ s force at Cascante . The battle would ultimately be decided by La Peña and Grimarest . By noon on 23 November 1808 they had received orders to move : La Peña to close the gap at Tudela and Grimarest to Cascante . Both men failed to carry out these orders other than La Peña moving two battalions and a detachment of provincial Grenadiers to Urzante . La Peña ’ s lack of movement allowed the two French cavalry brigades to pin him in place . The second French attack was made with much greater force . On the French left Morlot ’ s division attacked Roca ’ s division on the heights above Tudela . On the French right Maurice Matthieu ’ s division made a frontal assault on the smaller O ’ Neylle division while also making outflanking moves . The attacks on both left and right were successful with both Spanish divisions being pushed off the ridges they occupied . Then the French cavalry under Lefebvre - Desnouttes charged the gap between Roca and St . Marcq causing the collapse of the Spanish right . La Peña and Grimarest finally united at Cascante late in the day giving them a total of 21 , 000 men against Lagrange ’ s division which was 6 , 000 strong plus some dragoons . After the defeat of the rest of the Spanish army however La Peña and Grimarest withdrew after dark . Their poor performance was also reflected in the casualties of only 200 on the Spanish left compared to 3 , 000 on the right plus 1 , 000 prisoners . Aftermath . The Spanish armies of the left and right escaped from Tudela in two directions . The Aragonese forces on the right made for Saragossa where they would assist in the Second Siege of Saragossa starting on 20 December 1808 . The virtually intact Spanish left moved towards Madrid to defend that city . Napolean however moved quicker and after defeating a small Spanish army at Somosierra Pass on 30 November 1808 , arrived in Madrid on 1 December 1808 . Napolean ’ s strategy ultimately ended in total success with Madrid in his hands . He was then able to prepare for the reconquest of Portugal . Other Reading .
