In 19 July 711 Roderic King of the Visigoths lead an army of 100000 men against an Arabian army of 187000 men near Rio Guadalete. During the Battle the Muslim army engaged in a series of violent hit and run attacks, while the Visigothic lines maneuvered en masse. A cavalry wing that had secretly pledged to rebel against Roderic stood aside, giving the enemy an opening. Ṭāriq's cavalry, the mujaffafa, forming as much as a third of the total force and armored in coats of light mail and identifiable by a turban over a metal cap, exploited the opening and charged into the Visigothic infantry, soon followed by the infantry. The Christian army was routed and the king slain in the final hours of battle. The engagement was a bloodbath: Visigothic losses were extremely high, and the Muslims have lost as many as 3,000 men, or a quarter of their force.
WI Roderic saw that his tactics were useless against the hit and run hits of the Arabs and changed them quickly? WI Roderic's cavalry doesnt betray him? Could the Visigoths had won the battle? How is a potential Visigothic victory alters History? Could Hispania had remained in Gothic hands then or Arabs would try again?
