San Esteban de Gormaz
In his eastern territories, he united with Sancho I Garcés, king of Navarre, against the emir of Córdoba, Abd-ar-Rahman III. The Moors were put to rout at San Esteban de Gormaz (917). Arnedo and Calahorra were taken the next year from the Banu Qasi. The reaction of Abd-ar-rahman, however, was severe. In 920, he sent an army to recover Osma and San Esteban de Gormaz. He crossed into Navarre and defeated the Christians at Valdejunquera and took the bishops of Tui and Salamanca captive. Though intending to crush Pamplona itself, he turned around to deal with his immense booty.
