This book presents the history of Oberstleutnant Wilhelm Ritter von Thoma's units in the Spanish Civil War, from the tank crews to the infantry, and specialties.

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. [AuthorName]By Lucas Molina Franco and José Ma Arias Ramos[/AuthorName][AuthorBio][/AuthorBio][NumIllustration][/NumIllustration][CoAuthor][/CoAuthor][SubTitle]Legion Condor Ground Forces in the Spanish Civil War[/SubTitle][ColorPattern][/ColorPattern]
