This title tells the dramatic story of how the Royal Navy transformed ordinary citizens into first-rate and fearless sailors and navy personnel during World War II. It covers how they were recruited and trained, and how they endured life at sea in hostile waters, protecting convoys in the Atlantic, hunting submarines in the Mediterranean, and standing up to relentless air attacks in the Pacific. Told through vivid first-hand accounts of life onboard, it reveals what it was like to be a sailor navigating, patrolling, and fighting in the largest theatre of the war - the vast oceans.
