akivel összekeverte a krónikás, az Achila volt

the southwest (the provinces of Lusitania and western Carthaginiensis around the capital Toledo) in Roderic's hands and the northeast (Tarraconensis and Narbonensis) in the hands of Achila is confirmed by archaeological and numismatic evidence.
Achila's reign probably began shortly after Roderic's and lasted until 713.
