There followed a long and devastating war. Chac-xib-chac had been able to induce all the surrounding kingdoms except that of the Xius to join his forces. The Xius alone remained neutral. Hunac-eel, on seeing the hosts against him, had called to his aid a body of Mexican warriors who happened to be in Tabasco. The war raged for many years. Izamal was conquered, and one after another of the famous cities fell into the power of Hunac-eel and his foreign allies. Finally he attacked Chichen itself, killed Chac-xib-chac, and, aided by the novel machines of war of the Mexicans, sacked the city.
