San Esteban de Gormaz
In 993 Almanzor attacked Castile again, for unknown reasons, but failed to take San Esteban de Gormaz, simply looting its surroundings. He succeeded in taking it the following year, along with Clunia. Loss of San Esteban dismantled Castilian defenses along the Douro, while the taking of Clunia endangered lands south of the Arlanza.
