Musa Ibn Nosseyr sent his son Merwan to Tangiers, to wage a holy war upon her coast. Having, then, exerted himself together with his friends, he returned, leaving to Tarik Ibn Amru the command of his army which amounted to 1,700. Others say that 12,000 Berbers besides 16 Arabs were with Tarik: but that is false. It is also said that Musa Ibn Nosseyr marched out of Ifrikiya upon an expedition into Tangiers, and that he was the first governor who entered Tangiers, where parts of the Berber tribes Botr and Beranes resided. These had not yet submitted themselves. When he approached Tangiers, he scattered his light troops.
