Ian Trenowden was a retired Chartered Architect and Author. He published three histories The Hunting Submarine, Operations Most Secret and Stealthily by Night. He had an encyclopaedic knowledge of many aspects of the Second World War and was a respected authority on it - contributing to various publications and even consulting for Foyles War for television. He liked nothing better than to conduct research at the Imperial War Museum and Public Records Office and was the Honorary Librarian of a prestigious London Club.
The global response to the Bookbaby edition of the Hunting Submarine has been extraordinary. Testament to the quality of Ian's research and the tight knit world of the submariner. In producing this edition I have had to omit the book's index which I know would have irked him but it a small price to pay for being able to make it available again.
