First Carlist War

The Battle of Alegría de Álava was a Carlist victory during the First Carlist War, fought at a field in Chinchetru near Alegría-Dulantzi in Álava, Spain. The engagement brought together prominent Carlist commanders Tomás de Zumalacárregui and Manuel Iturralde against Liberal (Isabelino/Cristino) forces under Manuel O'Doyle. The victory contributed to the broader Carlist effort to consolidate control in the Basque region during the early phase of the war, a period in which Zumalacárregui was establishing the Carlist forces as a capable fighting force in the north.

The Battle of Alsasua took place in Navarre during the early phase of the First Carlist War, when Carlist forces under Tomás de Zumalacárregui were working to consolidate their position in the Basque and Navarrese countryside. Zumalacárregui's attack on a Liberal convoy moving between Vitoria-Gasteiz and Pamplona represented the kind of interdiction operation that characterized Carlist strategy in the region — disrupting Liberal communications and supply lines rather than contesting fixed positions. The engagement resulted in 300 Carlist casualties, indicating the Liberal convoy offered significant resistance despite being caught on the march. The outcome is not recorded, but the action reflects the contested nature of the road network linking Liberal-held urban centers in the north during this period of the war.

The Battle of Mayals, fought near the town of Mayals in Catalonia on April 10, 1834, was an engagement between Carlist forces under Manuel Carnicer Griñón and Liberal forces under José Carratalá. The Liberal victory checked the early expansion of the Carlist movement in Catalonia at a critical stage of the First Carlist War. By defeating the Carlists in the region during the conflict's opening months, the Liberal outcome constrained Carlism's ability to consolidate support and extend its reach into Catalonia, limiting one potential front in a war that was simultaneously being contested across northern Spain.

The Battle of Mendaza was an early engagement of the First Carlist War, fought in Navarre in December 1834. It brought together two of the war's central commanders on opposing sides: Tomás de Zumalacárregui leading the Carlists and Luis Fernández de Córdova alongside Marcelino Oráa commanding the Liberal (Isabelino/Cristino) forces. Beyond its place as an early action in the Navarrese theater of the conflict, no recorded outcome or broader operational consequence is available in the source record.

The Battle of Venta de Echavarri was a Carlist victory fought on October 28, 1834, during the First Carlist War. Occurring the day after the Battle of Alegría de Álava, it represented an immediate continuation of Carlist offensive pressure against Liberal forces. The engagement involved a Liberal force of 3,000 troops under Joaquín de Osma facing Carlist commanders Tomás de Zumalacárregui and Manuel Iturralde. Coming in such close succession to the previous day's action, the battle at Venta de Echavarri suggests a sustained Carlist operational tempo in the region, reinforcing whatever gains had been made at Alegría de Álava and further straining Liberal cohesion in the Basque theater of the war.

The Battle of Artaza took place in the Las Amescoas region during the First Carlist War, when Jerónimo Valdés, serving simultaneously as Minister of War, led a Liberal force of 22,000 against a Carlist force of roughly 5,000. The scale of the Liberal commitment — nearly four-to-one numerical superiority, directed personally by the minister responsible for the war effort — reflects the government's intent to deliver a decisive blow to Carlist resistance in the area. That Valdés came to Las Amescoas with the explicit aim of definitively destroying the Carlist forces underscores how seriously Liberal commanders regarded the Carlist presence there as a threat requiring resolution rather than containment.

The Battle of Mendigorría occurred at a pivotal moment in the First Carlist War, coming shortly after the death of Tomás de Zumalacárregui at the Siege of Bilbao. Zumalacárregui had been the Carlists' most capable field commander, and his loss at Bilbao left the movement in a weakened state of leadership. At Mendigorría, Vicente González Moreno assumed command in his place, facing a substantially larger Liberal force under Luis Fernández de Córdova and Diego de León y Navarrete. The Carlist force of 24,000 suffered around 1,500 casualties against the Liberals' 1,000, suggesting the engagement went against the Carlists. The presence of the Carlist pretender Don Carlos on the field underscored the stakes of the action for the legitimist cause. The battle reflected the broader difficulty the Carlists faced in sustaining offensive momentum following Zumalacárregui's death, a loss that the movement could not readily absorb during a critical phase of the war.

The Battle of Arlabán was fought at the heights between the provinces of Álava and Guipúzcoa during the First Carlist War. Liberal forces under Luis Fernández de Córdova, supported by the British Legion, French Legion, and units under Baldomero Espartero, succeeded in taking the Arlabán heights and Legutiano from Carlist defenders between 16 and 17 January 1836. The initial Liberal success proved short-lived: Carlist counterattacks on 18 January drove them back and inflicted heavy casualties, negating the territorial gains made in the preceding days. The engagement illustrated the difficulty Liberal forces faced in consolidating advances in the mountainous Basque interior, where Carlist forces retained the capacity to recover lost ground even against a combined force drawing on foreign legion support.

The Battle of Luchana, fought on the night of 23–24 December 1836 at Bilbao and its surrounding district, ended the Carlist siege of the city. Prior to the battle, Carlist forces controlled both the water and land routes into Bilbao, cutting it off from Liberal resupply and reinforcement. The Liberal victory under Espartero broke that encirclement and lifted the siege, securing Bilbao for the Isabelino cause. In the context of the First Carlist War, retaining Bilbao denied the Carlists a major urban and strategic prize in the Basque Country, a region central to their support base and war effort.

The Battle of Villarrobledo on September 20, 1836 delivered a major defeat to the Carlist forces under Miguel Gómez Damas, inflicting casualties of between 200 and 500 men and costing the Carlists significant quantities of munitions. Fought at Vega de San Cristóbal near Villarrobledo during the First Carlist War, the engagement saw a Liberal force roughly two and a half times the size of its opponent press the advantage in numbers to decisive effect. The loss of materiel alongside the manpower cost compounded the setback for the Carlist cause in this theater. Liberal commander Isidro de Alaix Fábregas was recognized for the victory with the title of Viscount of Villarrobledo and the Laureate Cross of Saint Ferdinand, reflecting the military and political weight attached to the outcome.

The Battle of Andoain, fought near the Basque village of the same name south of San Sebastián, was part of the ongoing Liberal effort to consolidate control in the Basque Country during the First Carlist War. Liberal forces under Leopoldo O'Donnell had seized Andoain on 9 September 1837, pushing the Carlist garrison across the Oria River. The subsequent Carlist counterattack, reinforced by troops from Navarre under José Ignacio de Uranga, tested Liberal forward positions in a strategically sensitive zone close to their principal stronghold at San Sebastián. Liberal casualties ranging between 100 and 750 against a numerically inferior Carlist force of roughly 3,000 suggest the counteroffensive was effective, reflecting the persistent Carlist capacity to contest Liberal advances in the northern theatre despite overall manpower disadvantages.

The Battle of Irún is listed in the context of the First Carlist War, though the supplied overview describes an engagement associated with a different conflict and set of commanders. Based strictly on the provided overview, the battle was the decisive engagement of the Campaign of Gipuzkoa and resulted in the capture of Irún by Nationalist forces under Alfonso Beorlegui. That capture severed the northern provinces of Gipuzkoa, Biscay, Santander, and Asturias from their supply lines and external support routed through France, with immediate operational consequences for the forces holding those provinces. By cutting this corridor, the battle isolated a substantial portion of the opposing side's territory, depriving it of arms and reinforcement at a critical stage of the wider northern campaign.

Oriamendi was an overwhelming Carlist victory during the First Carlist War, the first of three dynastic conflicts fought in Spain over royal succession and the character of the Spanish monarchy. With Liberal forces numbering approximately 9,300 and sustaining between 1,000 and 1,500 casualties, the battle demonstrated the Carlists' capacity to inflict significant losses on the Liberal military establishment. The engagement involved a Liberal command that included both Spanish generals and the British officer De Lacy Evans, reflecting the international dimension of Liberal support in the conflict. As a decisive Carlist success, Oriamendi reinforced Carlist military standing during the broader struggle that would continue until 1840.

The Battle of Maella on October 1, 1838 was a Carlist victory in the Aragonese theater of the First Carlist War. Despite being outnumbered — Carlist forces numbered roughly 3,500 infantry and 500 cavalry against a Liberal force of approximately 5,000 infantry and 300 cavalry — Ramon Cabrera's troops routed most of the Liberal army under Ramón Pardiñas, inflicting casualties of over 3,100 on a force that had entered the engagement with numerical superiority. The scale of Liberal losses relative to their total strength indicates a near-destruction of the opposing force, demonstrating Cabrera's capacity to conduct effective offensive operations in Aragon and undermining Liberal control in the region during a critical phase of the war.

The battle at Peñacerrada on June 20–22, 1838, produced an immediate and consequential shift in Liberal operational reach during the First Carlist War. Following their crossing of the Ebro after the Battle of Los Arcos, Liberal forces under Pedro Saarsfield and Manuel Lorenzo routed a Carlist force of 1,500 troops. The scale of the Carlist collapse was reflected in what followed: Saarsfield and Lorenzo entered Vitoria-Gasteiz and Bilbao within a week, encountering no further resistance. The rapid fall of these strategically significant towns indicated that the Carlist position in the region had been critically undermined, and that the Liberal advance had broken organized opposition across a substantial portion of the north.

The Cincomarzada marked a failed Carlist attempt to seize Zaragoza on 5 March 1838, during the First Carlist War. The city's successful resistance denied the Carlists a significant urban center and became a point of civic pride. The event is commemorated today as a popular holiday in Zaragoza, reflecting how the defense of the city against a Carlist force of 2,800 entered local memory as an act of collective heroism by its citizens.
