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. A very fine account of the joint Royal Navy and US Naval anti-submarine operation in the Western Approaches, to break the German blockade during The Great War. E. Keble Chatterton was well placed to write this history as he commanded a Motor Launch flotilla at Queenstown during this period.
