Airmen Without Portfolio: U.S. Mercenaries in Civil War Spain

The book affords a brief discussion of the role of U.S. aerial mercenaries from the early 20th century to the Spanish Civil War. Aside from its primary purpose as a study of the motivation and commitment of the U.S. aviators in the Spanish Civil War, the work chronicles the events leading to the outbreak of hostilities in Spain and the arrival of the foreign volunteers; the combat roles of Frank Tinker and his American comrades from January to July 1937; Tinker's return to the United States in August 1937 and a concise discussion of the remainder of the conflict; Tinker's suicide in Little Rock, Arkansas in June 1939; and a final review of the post-war careers of his squadronmates.
