The plaza, as mentioned in the preceding chapter, was defended on its three sides by low ranges of buildings, consisting of spacious halls with wide doors or vomitories opening into the square. In these halls he stationed his cavalry in two divisions, one under his brother Hernando, the other under De Soto. The infantry he placed in another of the buildings, reserving twenty chosen men to act with himself as occasion might require Pedro de Candia, with a few soldiers and the artillery, - comprehending under this imposing name two small pieces of ordnance, called falconets, - he established in the fortress. All received orders to wait at their posts till the arrival of the Inca. After his entrance into the great square, they were still to remain under cover, withdrawn from observation, till the signal was given by the discharge of a gun, when they were to cry their war-cries, to rush out in a body from their covert, and, putting the Peruvians to the sword, bear off the person of the Inca. The arrangement of the immense halls, opening on a level with the plaza, seemed to be contrived on purpose for a coup de theatre. Pizarro particularly inculcated order and implicit obedience, that in the hurry of the moment there should be no confusion. Every thing depended on their acting with concert, coolness, and celerity. *1 [Footnote 1: Pedro Pizarro, Descub. y Conq., Ms. - Relacion del Primer. Descub., Ms. - Xerez, Conq. del Peru, ap.
