Much has been written about Anglo-Irish relations over the period covered by this book, 1916-1945 but this is one of the best accounts i have read. It uses as its prism the story of British Intelligence and Ireland but it goes much deeper than that. The intelligence perspective allows for a comprehensive view of the British Government's attitude and provides a clear insight into the motivating forces, thoughts and predjudices that governed it. Sadly it is on the whole a story of incompetence, ignorance and misunderstanding that explains all the misssteps and bungling that characterised British policy until some commonsense and proper analysis finally began to produce some coherent policymaking from 1941 onwards.
The first period of intense British involvement lasted through until the Treaty in 1921 and if you ever wonder how Britain managed to lose Ireland this book will tell you. After that interest diminished again until De Valera took power in 1932 when a by now rusty machine was kickstarted into ineffective action. The Author gives an excellent account of the Agrement to give up the Treaty Ports in 1938 and the consequences thereof when war came. Predjudice and ignorance again proved predominent during the initial part of the war and nearly led to some disastrous decisions. Fortunately an effective link was formed with the Irish Army intelligence unit G2 and matters came under control and the intelligence machine actually worked effectively and ensured that although Ireland may have remained neutral it otherwise, albeit covertly, sided with the Allies on all issues of importance.
This is an important book well worth reading with many insights and analysis beyond the remit of its title.
