The Second World War was a truly global conflict and maritime power played a major role in every theatre of operations. Land campaigns depended on supplies transported by sea, and victory or defeat depended on the outcome of naval battles. So Leo Marriott’s highly illustrated two-volume account of the struggle sets naval actions in the wider strategic context as well as giving graphic accounts of what happened in each engagement.

This first volume concentrates on the Royal Navy’s confrontation with the ships and submarines of the German Kriegsmarine during the Battle of the Atlantic, the Arctic convoys and the struggle across the Mediterranean against the Italian navy to supply the opposing armies in North Africa. The Battle of the River Plate, the pursuit of the Bismarck, the PQ17 convoy to the Soviet Union and Operation Pedestal, the most famous convoy sent to relieve Malta, are among the episodes described in vivid detail and illustrated with a selection of striking photographs.

This concise but wide-ranging introduction to the naval war emphasizes the sheer scale of the conflict in every sea and shows the direct impact of each naval battle on the course of the war.
