Reggie Teague-Jones slipped into Russia in early 1918 on an undercover mission to try and prevent strategic materials such as oil and cotton falling into German and Turkish hands. He stayed on as semi-official British political representative to the self-appointed government of Transcaspia. In this role he acted as liaison between them and the British Indian troops which had been sent to help keep the Bolsheviks from Tashkent at bay. His other main task was trying to obtain funding to keep the hapless government propped up, at least until the British departed and left them in the lurch.
I wouldn't go so far as the previous reviewer to say this book is required reading for an understanding of the birth of communist Russia and events that shaped Central Asia. It is, however, a peek into a turbulent period of history in the company of an exceptionally able man - fluent in 5 languages besides English, self-confident to the point of arrogance, and happy to risk his neck whenever the opportunity arose. It is also an enthralling tale. And because it is based for the main part on a journal not intended for publication, it is rather more candid than other first-hand accounts of British spies active in Russia at this time. His opinion of his commanding officer, General Malleson, is particularly caustic.
In a postscript, Peter Hopkirk explains that Teague-Jones had to change his identity after the war - hence the "disappeared" in the book's title - to evade retribution from the Communists, who held him personally responsible for the shooting of the 26 Baku commissars. He is careful to exculpate himself of any blame in these pages, and one feels that a man who cheerfully admits to joining the Transcaspian secret police on raids to "liquidate" "undesirable elements" is unlikely to be coy about having gunned down a few inconvenient Bolshies. However, there are inconsistencies in Reggie's versions of events and, in a monograph on the British military intervention in Transcaspia, Michael Sargent voices the suspicion that "Teague-Jones might not have objected too strongly at the key meeting to the suggestion of shooting the commissars; he was certainly not the squeamish type." This book testifies to that.
