The Battle of Penas de San Fausto, which took place in 1834, is one of the most significant confrontations during the turbulent period of the 1st Carlist War. The war, which began in 1833, was a series of conflicts fought in Spain between the forces of the Carlists and the supporters of the constitutional monarchy, known as the Cristinos. This article will explore the details of the Battle of Penas de San Fausto, analyzing its participants, outcomes, and long-term impact on the 1st Carlist War.

Background: The 1st Carlist War
The 1st Carlist War was a bitter civil conflict that arose after the death of King Ferdinand VII of Spain in 1833. His death left the throne to his daughter, Isabella II, who was a child at the time. The succession crisis led to a struggle for power between two factions: the supporters of Isabella, known as the Cristinos or “Isabelinos,” and the supporters of her uncle, Don Carlos, who claimed the throne as the rightful heir. The Carlists, as they were called, advocated for a more traditional, conservative Spain with a decentralized monarchy and the preservation of the Spanish Catholic Church’s privileges.
The war raged on for several years, with both sides engaging in bloody confrontations throughout Spain. In 1834, the conflict had already seen significant battles, and the Carlists, although not yet victorious, had built considerable momentum in their struggle against the Cristinos.
The Battle of Penas de San Fausto: The Clash of Armies
The Battle of Penas de San Fausto, fought in 1834, was a notable engagement in the war. The battle took place in the mountainous region of the Basque Country in northern Spain, an area that had seen significant Carlist support. The terrain, with its hills and forests, played a crucial role in the battle, as the Carlists utilized the natural landscape to their advantage.
Participants in the Battle
The participants in the Battle of Penas de San Fausto were the Carlists and the Cristinos, with a third party also involved: the Viana forces. The Carlists, led by Don Carlos, were attempting to strengthen their position in the Basque region, where they enjoyed widespread support. The Cristinos, on the other hand, were fighting to protect Isabella II’s monarchy and the constitutional order established after Ferdinand VII’s death.
The Viana forces, a group aligned with the Cristinos, participated in the battle but did not emerge as the dominant force. Instead, they found themselves struggling against the better-prepared and more determined Carlist forces.
The Outcome of the Battle
The Battle of Penas de San Fausto ended in a decisive victory for the Carlists. Despite the Cristinos’ numerical advantage, the Carlists, under the leadership of their commander, were able to exploit their knowledge of the terrain and outmaneuver their opponents. The Cristinos, led by the forces of Viana and other regional commanders, were decisively defeated.
The Carlist forces inflicted heavy casualties on the Cristinos and successfully seized key positions in the region. This victory boosted the morale of the Carlists and further weakened the Cristinos’ control over northern Spain. As the Carlists continued to advance, they gained the support of local populations, which further solidified their position in the war.
The Aftermath and Strategic Impact
The Battle of Penas de San Fausto had far-reaching consequences for the 1st Carlist War. The victory of the Carlists in this engagement was a significant blow to the Cristinos and marked a turning point in the conflict. It demonstrated the Carlists’ ability to effectively utilize their local knowledge and gain the support of the population, which was essential for their long-term success in the war.
In the wake of the battle, the Cristinos struggled to maintain control over the Basque Country and other key regions in the north. The defeat at Penas de San Fausto contributed to the weakening of the Cristinos’ resolve and their inability to decisively counter the Carlist forces. While the war would continue for several more years, the victory at Penas de San Fausto signaled the growing momentum of the Carlists in their quest for the throne.
The victory at Penas de San Fausto also bolstered the reputation of Don Carlos and the Carlist cause. It helped to rally more supporters to their side and cemented their position as a formidable force in the ongoing struggle for control of Spain.
