From The General and the Jaguar: Pershing’s Hunt for Pancho Villa: A True Story of Revolution and Revenge, by Eileen Welsome (Little, Brown, 2009), Kindle pp. 325-327:
THE LEADERS of the Mexican Revolution all died violent deaths. Venustiano Carranza assumed the presidency in mid-March of 1917 and returned to Mexico City. Emiliano Zapata, who had carried on his fight for agrarian reform in nearby Morelos, had continued to taunt Carranza, writing insulting letters to him that were published in the daily newspapers. In an intricate plot, Carranza succeeded in having Zapata and his bodyguards assassinated on April 10, 1919.
The relationship between Carranza and Álvaro Obregón grew strained as the presidential elections of 1920 drew near. Obregón, who had done more than anyone else to ensure Carranza’s triumph, expected Carranza to step aside so that he could become president. But Carranza was reluctant to give up power, especially to a military man like Obregón. The Mexican Constitution banned the reelection of the president so Don Venustiano, unable to run again, did the next best thing and threw his support to Ignacio Bonillas, a minor politician whom he thought he could control. In response, Obregón’s home state of Sonora declared that Carranza was no longer Mexico’s legitimate president and named Adolfo de la Huerta, the Sonoran governor, as the interim leader. Other leaders throughout Mexico joined the revolt.
Carranza, realizing his time had come, decided to leave Mexico City. But first he systematically looted the government treasury, exhibiting the “quiet, tireless sleepless greed” that Edith O’Shaughnessy had once spoken of. (During his tenure, theft was so common that a new verb, carrancear, was coined.) Onto a long train, he loaded millions of dollars in gold and silver, priceless antiques, presses and ink used to print paper money, and even disassembled airplanes. As the train chugged toward Veracruz, it was attacked by insurgents and smashed by a locomotive loaded with dynamite. High in the mountains, the presidential entourage was finally halted at a point where the tracks had been torn up. Carranza proceeded on horseback, carrying what he could on pack mules and leaving millions in gold and silver behind. In the remote village of Tlaxcalantongo, he took refuge in an earthen hut. He ate with his usual deliberateness and then retired for the evening. At four o’clock on the morning of May 21, 1920, he awoke to the sound of gunfire and the cries “Viva Obregón!” and “Muera a Carranza!” He screamed at his guards to save themselves as multiple bullets slammed into his chest, killing him. He was sixty years old.
The Mexican legislature appointed Adolfo de la Huerta to serve as interim president until the elections could be held. An urbane and friendly man, de la Huerta wanted to heal the wounds of the revolution and granted amnesty to numerous revolutionaries. To Spanish author Vicente Blasco Ibáñez, de la Huerta seemed like “a virgin lost in a crowd of rabid and shrewd old hags who think they can become young again by rubbing against her.”
