Regarding George Patton's use of the SAA in the Mexican Punitive Expedition;
I do recall his actions in the 1916 incident, gave him some notoriety I believe, helps his rise in rank. IIRC, he was a cavalry officer and the '73 colt was a cavalryman's gun.
He was indeed a cavalryman, and competed in the 1912 Olympics in the Modern Pentathalon -- a cavalryman's event. It models a cavalryman carrying dispatches across the battlefield and starts as a steeplechase. The cavalryman's horse goes lame, so he has to run on, swim a river, shoot it out with his pistol and finish up with his sabre.
I know a story about that -- a fellow here in Mountain View, Arkansas, Jack Thomas, is fairly famous among those who restore old cars. A friend in the Library of Congress tracked down a 1915 Dodge Touring Car -- it was in a barn here in Arkansas -- and put Jack onto it.
That car (they were serial numbered) was purchased by the Army and issued to John J. Pershing for the Mexican Punitive Expedition. Jack restored it beautifully and had a huge scrap book about the car and its restoration. I looked through it and noticed he didn't have anything about Patton using the car when he killed Cardenas (the Number 3 man in Poncho Villa's army.) And I told him the story.
About a year later, Jack had the car on display at the courthouse square and I stopped by. He jumped up -- "You Son of a B####!"
It turned out he didn't believe me, and he called his friend in the Library of Congress who also didn't believe me -- so Jack had his scrap book printed up and was selling copies.
Then the friend came with an original newspaper article and faxed it to Jack -- it told all about how Patton was out with the car and a small escort, buying hay, heard Cardenas was home and went up to see.
Cardenas' home was a typical upper-class hacienda, built in the form of a hollow square. There were two other Villanistas with him, and they had their horses saddled and bridled in the courtyard. They heard the car coming, and their plan was to let the gringo pass, then slip out and go the other way. If he stopped, Plan B was to ride him down and shoot him.
Needless to say, against a pistol shot of Patton's caliber, Plan B didn't work.
The newspaper article had a photograph of Cardenas lashed to the hood of the Dodge -- Patton had him astride the hood, looking back through the windshield, with his hands tied to the side mirrors and feet lashed to the bumper.
The article and picture will be in the next edition of Jack's book.
