Each volume is signed and inscribed in ink on the front flyleaf by the author (to 'the Robertsons'). The second volume appears to have been published first, followed by the first, then the third volume. The wartime memoir, edited by Anthony Cumming, was published in 2017 under the title 'In Action with Destroyers 1939-1945: The Wartime Memoirs of Commander J A J Dennis DSC RN'. The publisher's blurb states 'The author was a very busy and very fortunate fellow. His was a war of almost non-stop action. Many of his contemporaries died around him but he survived. His only and very unsurprising complaint was that he was, from time-to-time, very tired. At 22 he was the Royal Navy's youngest destroyer first lieutenant and, at 26, one of its youngest destroyer captains. He sailed and fought in Asia, the Indian, Pacific, North Atlantic and South Atlantic oceans, the Red, Mediterranean and North seas and the Arctic. He travelled far and fast'. An online obituary records that he 'came to Canada in 1958 after a career in the Royal Navy and a very active war in destroyers. As a young lieutenant he had distinguished service in destroyers in the Atlantic and Mediterranean. His memoir (privately published), including a chapter on his instrumental part in the early Enigma campaign is held in the archive of the Imperial War Museum and has been referenced several times'.
