Sancho Garcés III de Pamplona
The Battle of Calatañazor was a legendary battle of the "Reconquista" that supposedly took place in July 1002 at Calatañazor between an army of invading Saracens under Almanzor and a force of Christian allies led by Alfonso V of León, Sancho III of Navarre, and Sancho García of Castile. Almanzor, who historically died the night of 10–11 August, is said to have died of wounds received in the battle. Its ahistoricity was first demonstrated by Reinhart Dozy in 1881. The French Arabist Évariste Lévi-Provençal attributed the destruction of San Millán de la Cogolla by the Saracens to the campaign of Calatañazor.
