Two wars and three Cs

When in 1909 a 50-year-old retired naval officer, Mansfield Cumming, was asked to set up what became today’s Secret Intelligence Service — better known as MI6— the suggestion that there might one day be an official history would have been unthinkable.

When in 1909 a 50-year-old retired naval officer, Mansfield Cumming, was asked to set up what became today’s Secret Intelligence Service — better known as MI6— the suggestion that there might one day be an official history would have been unthinkable. Indeed, for the next 85 years, MI6 had no official peacetime existence, let alone any thought of a history. Cumming later remarked that if ever he published an autobiography it would be quarto, bound in vellum and of 400 pages — all blank.

Change began with the Intelligence Services Act of 1994, which put SIS on a statutory footing, and the move to its prominent new headquarters, Vauxhall Cross. This was followed by William Waldegrave’s Open Government initiative, which led ultimately to this book (as well as to Christopher Andrew’s recent history of MI5).
