 Bel Alchad, fearful of the reaction of the Tunisians and the advance of Christian troops, decided to sign an alliance with Ferdinand III for a period of one year.Bel Achad was killed by Axataf, the commander of the garrison in Seville, in March 1246.This violent act led to the end of the truce with Fernando, who, free of his commitment to Bel Alchad, directed his attention to Seville and began with preparations to attack the city.
