Lockhart was in the consular service in Moscow during the war, and in 1918 acted as special agent in negotiations with the Bolsheviks. His book is certainly one of the most valuable studies of the evolution of Russian opinion during the war, of the gradual discrediting of the monarchy, of the revolution and the Kerensky régime. Most important, however, is his narrative of negotiations with Lenin, Trotsky and other Bolshevik leaders, of whom he gives vivid pen pictures. He was in favor of Allied intervention with the consent of the Bolsheviks, but was eventually overruled and placed for a time in danger of his life. Enough has been said to indicate the nature of the book and to point out its considerable value for all students of the Russian overturn.
