In today’s episode I talk more about Alvar Núñez Cabeza de Vaca and the first recorded exploration of today’s Texas.  How the raft captained by Cabeza de Vaca and one other raft came ashore on present-day Follets Island, which is a little southwest of Galveston and northeast of Matagorda Bay. The total members of that party was just about ninety folks and included at least one African slave, and yes at that time the Spanish had slaves, both African and Indians,  and that would play a role in later Spanish political difficulties in both Mexico and New Mexico and to a lesser extent Texas. 
How of the ninety who started only 4 survived to return to Mexico City and how Cabeza de Vaca became known for his trading with the natives, his descriptions of Indian life, and his naming of 17 Indian tribes. How he and his crew became slaves and eventually escaped and ended up walking over 2,400 miles to return to Mexico City.
