Knight of the Tiger — W. Michael Farmer

"Knight of the Tiger is gripping historical fiction taken from stories of those who lived the times to reveal a portrait of betrayal and justice seen through the eyes of betrayed and betrayer in the 1915/1916 civil war between Pancho Villa and Venustiano Carranza for control of Mexico. Henry Fountain, not long out of medical school, helps Pancho Villa, a good friend from his youth, only to escape execution as Villa descends into darkness raging against his betrayal by the United States and his inability to win battles with cavalry charges against machine guns and soldiers in trenches.
