When de Vaca's fleet landed on
an island inhabited by Indians, they treated them really well, unlike most other conquistadors would have. They also
did another very respectful thing, they learned the natives' language instead of treating them like they weren't as smart
as the Spaniards because they didn't know Spanish. This earned them more respect and kept them from a possible war in
the future. He charted many lands and contributed to future conquests. He also claimed land near present
day Tampa Bay.
