[IV-72] Such is the account given by Ixtlilxochitl and Veytia. Brasseur's version, although founded on the same authorities, differs widely. According to this version, Topiltzin Acxitl remained in Tollan; Quauhtli and Maxtlatzin with the aged Huemac marched to meet the foe. After a fierce conflict near Tultitlan, lasting several days, the army was driven back to Tollan. The king resolved to burn the city and leave the country. For the burning of Tollan, Sahagun, _Hist. Gen._, tom. i., lib. iii., p. 255, is referred to, where he says, 'hizo quemar todas las casas que tenia hechas de plata y de concha,' etc., referring to the departure of Quetzalcoatl for Tlapallan. The Quetzalcoatl alluded to may be either Acxitl or Ceacatl. Retreating to Xaltocan and then towards Teotihuacan, a final stand was made by Huemac, Xochitl, Maxtlatzin, and Huehuemaxal (Huehuetenuxcatl?) against the Chichimecs. The Toltecs were utterly defeated, and of the leaders Xochitl and Quauhtli fell, Acxitl concealing himself for several weeks in the caves of the island of Xico. _Hist. Nat. Civ._, tom. i., pp. 405-9.
