This book is a comparative study of the evolution of the German navy in the second half of the nineteenth century. It examines the development of strategy, especially commerce-raiding, in comparison to what other navies were doing in this era of rapid technological change. It is not an insular history, merely listing ship rosters or specific events; it is a history of the German navy in relation to its potential foes. It is also a look at a new military institution involved in an inter-service rivalry for funds, technology and manpower with the prestigious and well-established army.
