With help of the Ottomans, the Wattasids under Ali Abu Hassun were able to conquer Fez once more in early 1554, but that conquest was short-lived, and Mohammed ash-Sheik was able to vanquish the last Wattasids at the Battle of Tadla, and recapture the city of Fez in September 1554. During the Ottoman Siege of Oran (1556), Mohammed ash-Sheikh, who was allied with the Spanish, managed to capture Tlemcen from the Ottomans. With the final victory of the Saadi and the death of Ali Abu Hassun in 1554, the war was decided.
