Although Ccapac Yupanqui conquered the city of Cajamarca, the supply line was poorly made and controlled, as he traveled hastily to Cajamarca without building or conquering on much of the journey from central Peru, Ccapac Yupanqui believed Inca army's supply line of troops and supplies wasn't optimal and thus put at risk the Inca control over the newly acquired city of Cajamarca. Ccapac Yupanqui left part of his troops garrisoned at Cajamarca, and then he returned to Tawantinsuyu in order to ask for reinforcements and conducted a more extensive campaign in the territories of central Peru, building a great quantity of infrastructure (such as tambos, colcas, pukaras, etc.) along the Inca road. Incas remodeled Cajamarca following Inca canons of architecture, however, not much of it has survived since the Spanish did the same after conquering Cajamarca.
