The Sanhaja confederation, which consisted of a hierarchy of Lamtuna, Musaffa and Djudalla Berbers, represented the military's top brass. Amongst them were Andalusian Christians and heretic Africans, taking up duties as
diwan al-gund, Yusuf's own personal bodyguard; including 2,000 black horsemen, whose tasks also included registering soldiers and making sure they were compensated financially. The occupying forces of the Almoravids were made up largely horsemen, totaling no less than 20,000. Into the major cities of al-Andalus, Seville (7,000), Granada (1,000), Cordoba (1,000), 5,000 bordering Castile and 4,000 in western Andalusia, succeeding waves of horsemen in conjunction with the garrisons that had been left there after the Battle of Sagrajas, made responding, for the Taifa emirs, difficult. Soldiers on foot used bows & arrows, sabres, pikes, javelins, each protected by a cuirass of Moroccan leather and iron piked shields. During the siege of the fort-town Aledo, in Murcia, captured by the Spaniard Garcia Giménez previously, Almoravid and Andalusian hosts are said to have used catapults, in addition to their customary drum beat.
