Those of us who read _With the Persian Expedition_ know something about the Hush-Hush Army; enough, at any rate, to whet our appetites for more. Let me then recommend _The Adventures of Dunsterforce_ (ARNOLD) to your notice, and assure you that it is a most lively account of as strange an enterprise as any that the War brought forth. Briefly, the object of General DUNSTERVILLE'S mission was to prevent German and Turkish penetration in the area of the Caucasus, Baku and the Caspian Sea. In January, 1918, he set out from Baghdad with what he calls "the leading party." Continually hampered by lack of men, the mission failed to achieve its original object; but what it accomplished in most difficult circumstances was of great value to the Allies. The conditions at the time when the author sailed from Enzeli with his "Dunsterforce" to raise the siege of Baku were delightfully cosmopolitan. He describes himself as "a British General on the Caspian, the only sea unploughed before by British keels, on board a ship named after a South African Dutch President and whilom enemy, sailing from a Persian port under the Serbian flag to relieve from the Turks a body of Armenians in a revolutionary Russian town." "Let the reader," he adds, "pick his way through that delirious tangle, and envy us our task who may." After pursuing the tricky course of this astounding adventure I confess myself lost, not in its mazes, thanks to an excellent map, but in profound admiration for "Dunsterforce" and its leader.
