The Battle of Alsasua, also known as the Battle of Altsasu or la Acción de la Venta de Alsasua (in Spanish "action of the inn at Alsasua"), occurred on April 22, 1834, in Navarre, Spain, during the First Carlist War. Carlist general Tomás de Zumalacárregui attacked a convoy led by the Liberal general Vicente Genaro de Quesada traveling from Vitoria-Gasteiz to Pamplona at the town of Alsasua. The Liberals suffered many casualties and Zumalacárregui took many prisoners, as well as half a million reals. The decision of both generals to execute most of their prisoners after a failed exchange negotiation set the ruthless tone with which POWs would be treated throughout the conflict. In addition, it strained Liberal supply lines in the area and was part of Zumalacárregui's successful guerrilla campaign until his death in the siege of Bilbao in 1835.
