During World War II, Britain's Royal Navy has to expand more than sevenfold, in the faces of the threat of invasion, enemy bombing and the need to carry out campaigns all around the world. To find officers for this force it had to move well outside its normal supply of boys trained from the age of 13. It started by recruiting yachtsmen and giving them a smattering of naval discipline before sending them to sea. Then it sent possible officers into action as ordinary seamen, to live a hard and dangerous life in destroyers. One of Britain's leading naval historians looks at the social background of British wartime naval recruits, the training methods, the personal experiences of those involved and what they had to learn to become an officer of the watch on the bridge of a warship, or even the captain of a landing craft or frigate in the Second World War. The book draws widely from personal experiences of those who served and presents a rich collection of wry quotes and numerous anecdotes from household names such as Alec Guinness, Evelyn Waugh, Nicholas Monsarrat and George Melly as we follow them through the rigours of the war at sea. It has much to say on seamanship, naval technology, leadership and organisation.
