Edward Keble Chatterton (1878-1944) was a sailor and prolific writer who is best known for non-fiction works. His voyages across the English Channel, to the Netherlands, around the Mediterranean and through the French canals led to many articles and books. Joining the R.N.V.R. at the outbreak of the Great War he commanded a motor launch flotilla, leaving the service as a Lieutenant Commander. In 1918 he was appointed to the Naval section of the Official History Committee, where he worked until 1922. Keble Chatterton is unquestionably one of the most important and vivid nautical authors of the past century using both first hand accounts from the people that were there at the time and having the opportunity to access to official documents. Chatterton recorded the maritime history of Britain at its most momentous point of change, from sail to steam, from the advent of the submarine to the carrier. Writing with narrative flair and a passion for the subject, Chatterton places the reader in the middle of this full and complete account of the U-boat campaign from its initial stages when they scored a number of impressive successes against the Royal Navy, the attacks on merchant ships, and the period of unrestricted submarine warfare.
