Ла-Буреба
In 867, another son of Emir Muhammad I, al-Hakam, led another raid against Count Rodrigo's lands without ever entering the battle. In the same year, the Cordobans faced serious internal difficulties that lasted a decade and a half. This allowed the Castilians under Rodrigo to regain control of the fortresses of La Bureba, Pancorbo (in 870) and Cereso de Rio Tiron, while the Alavians took possession of Cellorigo.
