This book examines how the Royal Navy protected our shores and wider interests through the First World War and the one that was to follow, from the northern patrol lifelines of the Atlantic, Arctic and Mediterranean convoys and increasingly sophisticated amphibious operations that would mark it out in the Second. The book ends with chapters on The Falklands War and Royal Navy\047s anti-piracy role and involvement in humanitarian crises. This visually stunning volume is complemented by 15 loose facsimile documents that include letters and diary entries, war reports and other items of memorabilia that bring an immediacy to the events being described. Without the Royal Navy in two World Wars, Britain would have at best lost, and worst ceased to exist. This book salutes the services\047 incredible achievements over the last 100 years.
