 Many Berber fighters had nothing but stones and knives, dressed in a mere loin cloth, heads shaved in puritan fashion.But they made up for this in knowledge of the terrain, excellent morale, and a fanatical Sufrite-inspired religious fervor.The Berber and Arab armies finally clashed at the Battle of Bagdoura (or Baqdura) in October-November, 741, by the Sebou river (near modern Fes).
