In October 1936 two German ships arrived in Spain loaded with a Panzer I
company and all the services and personnel to establish Franco's army's
first armored unit, the so-called Panzer-Gruppe Drohne. The Third Reich
chose a pioneer in the development of German ground forces to command
this contingent - Oberstleutnant Wilhelm Ritter von Thoma. This book
presents the history of von Thoma's units in the Spanish Civil War, from
the tank crews to the infantry, and specialties.
