The opening months of World War II saw Britain's Royal Navy facing a resurgent German navy, the Kriegsmarine.

Following the German invasion of Denmark and Norway in early April 1940, British and German destroyers would clash in a series of battles for control of the Norwegian coast. The operational environment was especially challenging, with destroyer crews having to contend with variable weather, narrow coastal tracts and possibility of fog and ship breakdowns.

In two engagements at Narvik, the Royal Navy entered the harbour and attacked the loitering German destroyers who had dropped off mountain troops to support the German invasion. The raids were devastating, halving at a stroke the number at Hitler's disposal.

Employing specially commissioned artwork and drawing upon a range of sources, this absorbing study traces the evolving technology and tactics employed by the British and German destroyer forces, and assesses the impact of the Narvik clashes on both sides' subsequent development and deployment of destroyers in a range of roles across the world's oceans.
