Third Carlist War: Battle of Alpens ambush in Catalonia

Background. The Third Carlist War began in 1871, after the overthrow of Isabella II in the 1868 La Gloriosa revolution and the 1870 coronation of Amadeo I of Savoy as King of Spain. The Carlist cause in Catalonia had been successful since the initial uprising in 1872, and raiding parties carried out guerrilla activities across Catalonia under generals including Tristany, Savalls, and Castells.

The Ambush. The first major encounter between the opposing armies occurred at Alpens on July 9, 1873. A government column led by José Cabrinety was ambushed by Carlist forces under Francisco Savalls. The legacy row claims 800 men were killed or captured, but the supplied passages do not verify this specific casualty figure or the extent of the destruction.

Strategic Context. The war saw regime changes in Spain, including the proclamation of the First Spanish Republic in February 1873 after the abdication of Amadeo I. Carlist parties remained active in Catalonia, engaging government forces in heavy fighting. In other theatres, 1874 marked the limit of the Carlist advance, with the failure of the siege of Bilbao and battles near Estella.
