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. 47-48:
Villa used long trains to transport his soldiers from city to city. On top of the boxcars rode pigs, chickens, children, and soldaderas—wives, daughters, and even grandmothers who served as helpmates and nurses and fellow fighters. His pride and joy was his hospital train, which consisted of forty enameled boxcars staffed with Mexican and U.S. physicians and supplied with the latest surgical appliances. With its bright blue crosses and the words Servicio Sanitario stenciled on the sides, the hospital train followed Villa’s troops into battle and transported the most severely wounded back to hospitals in the cities. He had a boxcar for correspondents, a boxcar for moving-picture men, a boxcar for his cannons and extra railroad ties, and a caboose, which he used for his headquarters. Painted gray and decorated with chintz window curtains, the caboose was big enough for a couple of bunks and a partitioned area for his cook. In the early days, Villa would sit in his caboose in his blue underwear while as many as fifteen generals lounged at his feet to argue and plot strategy for their next campaign. Hanging on the walls above them were pictures of Villa on one of his frothing horses; the querulous Don Venustiano; and Rodolfo Fierro, Villa’s handsome and ruthless friend, who was christened el carnicero—the butcher—after he had made a sport of shooting three hundred prisoners as they tried to escape over a corral wall.
If Fierro represented the dark side of Pancho Villa’s nature, then the aristocratic and exquisitely mannered Felipe Ángeles represented the good. Ángeles, the army general who had been detained along with Madero and his vice president, had been educated at the Colegio Militar and excelled at mathematics and artillery science. He was in the federal army when the revolution broke out and offered to fight against the revolutionaries. But he soon became personal friends with Madero during the latter’s brief presidency. After Madero was killed, Ángeles joined Don Venustiano’s counterrevolution. Disgusted by Carranza’s opulent lifestyle and the preening sycophants who surrounded him, Ángeles eventually aligned himself with Pancho Villa’s División del Norte. Villa revered Ángeles’s intellectual and military capabilities and his rigorous honesty. While he considered himself far too ignorant and uneducated to govern a turbulent country like Mexico, Villa often thought Ángeles could be the next president.
