+1 on "RIP Ford's Texas". Check out this 1958 Dissertation 😎 I haven’t perused it all yet, I dunno if it will mention a sojourn into Mexico after runaway slaves but it fills out many of the details of Ford’s exploits: “RIP” Ford, Texan: The Public Life and Services of John Salmon Ford, 1836-1883
"...if the gentlemen of Virginia shall send us a dozen of their sons, we would take great care in their education, instruct them in all we know, and make men of them." Canasatego 1744
