In 1913, Ambrose Bierce joined the army of Pancho Villa as an observer. The last known communication received from Bierce was a letter dated December 26, 1913. Bierce, satirical writer and author of The Devil’s Dictionary, apparently vanished off the face of the earth. Oral tradition in Sierra Mojada, Coahuila states that Bierce was executed by firing squad in the town cemetery there.  Perhaps Bierce made the mistake of sharing some satires with Pancho Villa.
AMBROSE BIERCE: Hah, hah, Pancho. This war of yours is a by-product of the arts of peace.
PANCHO VILLA: (Suspicious of the gringo) Hey señor. Perhaps you do not like your tongue so well.
Ersjdamoo, when a lad, once chatted with an old man who had been with General John Pershing when Pancho Villa was hunted by the United States. “We just used to call him [Pershing] Jack,” said the old man. “We’d say, ‘Hey, Black Jack.'” The hunt for Villa began after he had entered the United States with his army. In Columbus, New Mexico there was a full-scale battle between Villistas and the United States Army. On May 15, 1916 Villa and his men attacked Glenn Springs, Texas. On June 15th they killed four soldiers at San Ygnacio, Texas. On July 31st there was an attack at Fort Hancock Texas.  Above you can hopefully see a photo from Fort Bliss, Texas, circa 1913. It shows (left to right) Generals Alvaro Obregon, Pancho Villa, and John “Black Jack” Pershing. (Behind Pershing stands Pershing’s aide, First Lieutenant George Patton.)
Wrote author Antony Sutton, “The raids upon the U.S. by the Villa and the [Venustiano] Carranza forces were reported in the New York Times as the ‘Texas Revolution’ (a kind of dry run for the Bolshevik Revolution) and were undertaken jointly by Germans and Bolsheviks.” There was a “link between Bolshevik interests in the United States, German activity, and the Carranza forces in Mexico.” The Carranza government had a constitution written by Trotskyites and “was a government with support on Wall Street.” 
Later, in the 1930s, Leon Trotsky himself came to stay in Mexico after he ran afoul of Josef Stalin. As for the German involvement in Mexico, recall the 1917 Zimmerman Telegram mentioned in Trotsky Was Mr. Moneybags, the Ersjdamoo’s Blog entry of April 26, 2014. The German presence in Mexico is also alluded to in the 1969 movie, The Wild Bunch. (See image hopefully above.)
Wall Street involvement in the border raids by Pancho Villa is corroborated by a letter from Lincoln Steffens, an American Communist, to “Colonel” Edward Mandell House, an aide to U.S. President Woodrow Wilson:
My dear Colonel House:
Just before I left New York last Monday, I was told convincingly that ‘Wall Street’ had completed arrangements for one more raid of Mexican bandits into the United States: to be so timed and so atrocious that it would settle the election… 
Since the Villa raids were going on in 1916, presumably “the election” referred to by Lincoln Steffens would have been the 1916 U.S. presidential election, won by Woodrow Wilson who “kept us out of war (in Europe)”. But then Wilson no longer “kept us out of war” during his second term. Instead, we made the world “safe for democracy.”
What did Ambrose Bierce find out in Mexico which caused him to be disappeared off the face of the earth? Granted, Bierce was an old man by then – an “Old Gringo” as referred to by the 1989 movie of that title. In the “Old Gringo” movie, Ambrose Bierce is shot in the back by a Mexican General. If Ambrose Bierce had found out disturbing things about Germans, Bolsheviks, and Wall Street, that might have been enough to get him killed.
