One guy of interest here is James Grant, what on earth is a Scottish physician and former British East India Company guy doing in the middle of all of this?

Turns out one of his descendants wrote a book claiming that all along Grant was working for the British.....

Entirely believable given the influence the Brits, as the unchallenged major world power at the time, wielded inside Mexico.

Worth a look, especially at $5 used, if nothing else for the detailed descriptions of the actions of Grant and Johnson in the Matamoras campaign and the fights at San Patricio and Agua Dulce.
