After recruiting Jusepe, Humana and Leyva found additional Spanish and Indian soldiers and servants in Santa Barbara, Chihuahua and proceeded onward into what is today New Mexico.
[1] Humana and Leyva and an unknown number of Spanish and Indian soldiers and servants left New Mexico to explore eastwards, presumably in search of rich kingdoms which were rumored to be just over the horizon.
Jusepe said they found abundant water in many marshes, springs, and arroyos (brooks) as well as great numbers of plum trees and nuts.
Humana spent an afternoon and morning in his tent apparently writing up his account of the dispute and then sent a soldier, Miguel Pérez, to summon Leyva.
Jusepe was taken captive by Apaches and lived with them for a year until he escaped or was set free and made his way back to New Mexico.
By this time (1596), Oñate and a large group of settlers had arrived in New Mexico and Jusepe took up residence at the San Juan Bautista Pueblo.
[2] In 1601, Jusepe guided Juan de Oñate, the founder of New Mexico and governor of the new colony, on a large expedition to the Plains.
What does not fit very well with this possible route is Jusepe's comment that three days beyond the Great Settlement that they came upon "such a multitude of buffalo that the plain—which was level, for there are no mountains—was so covered with them that they were startled and amazed at the sight."
If the Great Settlement were at Wichita or Arkansas City, three days travel toward the Missouri River would place the expedition in the rocky and rolling Flint Hills not a plain.
The Platte River in Nebraska has also been suggested, but that would require a major recalculation of the route of Humana, Leyva, and Oñate and the location of the Great Settlement.
