a spanish contemporary chronicle estimated abu hasan's army at 40,000 knights and 400,000 infantry; figures regarded as grossly inflated by callaghan. another account put forth 53,000 knights and 600,000 infantry for the moors. a third chronicler postulated 70,000 knights and 400,000 infantry for the marinids and 7,000 knights and 700,000 infantry for granada. archbishop gil de albornoz asserted a strength of 40,000 knights and 400,000 infantry for the combined muslim force. the lowest figure is provided by rodrigo yánez's account, claiming that abu hasan deployed 60,000 men and that transporting the force across the straits of gibraltar took four months. yánez's estimate is dismissed by callaghan. the 17th century historian ahmed mohammed al-maqqari, relying on an earlier text, also estimated 60,000 men as abu hasan's force. granada had 7,000 knights and the marinids may have mobilized up to 60,000 men. a christian militia probably fought for the emir of granada at the battle. one marinid prince fought on the castilian side.
