While the enduring image of the Great War is of the bloody stalemate on the Western Front, the overall shape of the war arose out of its maritime character. In this illustrated history, Norman Friedman describes rapid wartime changes not only in ship and weapons technology but also in the way naval warfare was envisaged and fought. Melding strategic, technical, and tactical aspects, Friedman approaches the conflict from a fresh perspective and demonstrates how its perceived lessons dominated the way navies prepared for World War II.
