The Spanish were able to complete their escape to Tlaxcala. There, they were given assistance, since all 440 of them were wounded, with only 20 horses left. Maxixcatzin, Xicotencatl the Elder and Chichimecatecle told Cortés's men: "Consider yourselves at home. Rest...do not think it a small thing that you have escaped with your lives from that strong city...if we thought of you as brave men before, we consider you much braver now.":306-07 Cortés got reinforcements when the Panuco River settlement was abandoned, and supply ships arrived from Cuba and Spain. Cortés also had built 13 brigantines then had them mounted with cannons, turning Lake Texcoco into a strategic body of water to assault Tenochtitlan. Xicotencatl the Younger, however, sought an alliance with the Mexicans, but was opposed.:309-11 Cortés sent Diego de Ordaz, and the remnants of Navarez's men, on a ship to Spain, and Alonso de Ávila on a ship to Santo Domingo to represent his case in the Royal Courts.:311 Cortés was able to pacify the country, after the indigenous realized the Spaniards put "an end to the rape and robbery that the Mexicans practised." Finally, Xicotencatl the Elder, baptized as Don Lorenzo de Vargas, agreed to support Cortés's expedition against Texcoco. According to Bernal Diaz, he sent more than ten thousand warriors under the command of Chichimecatecle as Cortés marched on the day after Christmas 1520.:309, 311-12
