in the square of Tlatelolco. The principal one, being of much greater width than the other two, might rather be called a causeway than a street, since it was flanked by deep canals on either side. Cortés divided his force into three bodies. One of them he placed under Alderete, with orders to occupy the principal street. A second he gave in charge to Andres de Tápia and Jorge de Alvarado; the former a cavalier of courage and capacity, the latter a younger brother of Don Pedro, and possessed of the intrepid spirit which belonged to that chivalrous family.
