The cast of characters engaged in and around the events leading up to the US invasion of Veracruz in April 1914 were:
Petroleum interests around Tampico at the time were controlled by Americans, but around Veracruz, it was British, with Weetman D. Pearson, aka Lord Cowdray, representing the British consortium. Pearson enjoyed the ferocious support Sir Lionel Cardon of the British Consulate in Mexico City, who had represented British interests in Mexico for decades. Pearson's secretary was J.B. Body and Cardon's secretary was Thomas Hohler. Cardon will figure big in our story.
