San Esteban de Gormaz
Recognizing he had underestimated the power of Ordoño II, in 920 Abd al-Rahman mustered another powerful army to reclaim the territories lost after the previous campaign. He captured the forts of Osma and San Esteban de Gormaz. After defeating King Sancho Garcés I of Navarre and the king of León at Valdejunquera on 26 July, he penetrated into Navarre, overcoming Aragon by the classic route of the invasions from the south. Abd al-Rahman reached the Basque city of Pamplona, which was sacked and its cathedral church demolished.
