This is the most long-winded inscription at the monument:

I am the captain General of the Providence of New Mexico for the King our Lord, passed by here on the return from the pueblos of Zuni on the 29th of July the year 1620, and put them at peace at their humble petition, they asking favors as vassals of his Majesty and promising anew their obedience, all of which he did, with clemency, zeal, and prudence, as a most Christian-like gentleman extraordinary and gallant soldier of enduring and praised memory.
