A D. Pedro Alvarado le cupo el camino que va derecho de Tlacupa al Tlatilulco. El capitán D. Hernando Cortés se puso en Coyoacan, y guardaba el camino que va de Coyoacan á México. De acia la parte del Tlatilulco se comenzó primero la guerra en un lugar que se llama Nextlatilco, y llegaron peleando hasta el lugar que se llama Nonoalco, donde está ahora una iglesia que se llama san Miguel, y los Españoles se retrugeron; no ganaron nada en esta escaramuza.

Don Pedro Alvarado was given the road that runs straight from Tlacupa to Tlatilulco. Captain Don Hernando Cortés took up his post at Coyoacan and guarded the road from Coyoacan to Mexico. The war began first on the Tlatilulco side, at a place called Nextlatilco. They fought their way as far as a place called Nonoalco, where there is now a church called San Miguel, and the Spaniards fell back. They gained nothing in this skirmish. Captain Don Hernando Cortés also attacked the Mexicans from his side, along the road called Acachinanco, and the Mexicans fought back hard.
