During the Second World War the Royal Navy was the most powerful of Britain's armed forces.Its sailors fought across the globe in vast battleships and claustrophobic corvettes, makeshift minesweepers and silent submarines.They endured nerve-wracking convoys, fought epic gun battles, carried out deadly secret missions, rescued armies and landed the largest invasion force in history.Naval power was the foundation of Britain's war effort, and sailors shaped the nation's destiny.Drawing on hundreds of contemporary diaries and letters, Glyn Prysor's original and gripping narrative evokes the triumph and tragedy, horror and humanity of the war at sea, bringing to life the sailor's war as never before.
