Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. The Royal Navy by John Leyland was first published in 1914. The book contains an account of the nature, character and development of the British Navy, revealing its roles in maintaining the security of the country and supporting the growth of the Empire.
