The Journal of Military History
Stephen Harriss book is the most formidable and scholarly account yet written about British intelligence operations in the Crimean War. The basic conception is original and interesting; the issues are real and clearly conceived; the sources used unrivalled in extent; and the entire treatment rests on an exceptional combination of perspicacity and sensitivity, both of thought about, and feeling for, intelligence operations.
Soldiers of the Queen, Vol. 98 (Sept. 1999)
Attractively produced ... it is an interesting and competent work and is definitely recommended to all students of the Russian war.
Choice, Vol. 37, No. 2, Oct. 99
Harris ... has done an excellent job of analyzing and comparing the various intelligence reports available to Lord Ragland and his successor in the Crimea.
RUSI Journal, Feb 2000
This admirable, slim book has a simple thesis ... The book is a welcome revision of the stereotype of British intelligence buffoonery. For military historians it contributes to the changing views of Crimean generalship ... But the book is full of material with a bearing on modern intelligence doctrine.
The International History Review, Vol 22, No 2, June 2000
Harris has done a careful and commendable job.
