The Spaniards secured the valley and remained in position for three or four days without facing any significant battles or coordinated Inca attacks. Juan quickly understood why he faced limited Inca resistance in the valley when a horseman dispatched by Hernando Pizarro informed Juan that Inca warriors had amassed on the hills surrounding Cusco. The Inca emperor did not attack Cusco at once; instead, he waited to assemble his full army estimated at between 100,000 and 200,000 men strong around the city (some sources suggest numbers as low as 40,000).
