The British C'ampaign in France and Flanders, 1915. By Sir

Arthur Conan Doyle. (Hodder and Stoughton. 7s. lid. net.) — In the fourth volume of his valuable and interesting history of the British campaigns on the Western Front Sir Arthur Conan Doyle describes the great offensive of 1917, which began magnificently with Vimy and Mesaines, but was checked by the excessive rainfall of the summer and autumn on the Flanders ridges, with the victory and partial reverse before Cambrai as a supplementary operation at the close of the year. The author gives for the first time the order of battle in the several actions, and mentions the units concerned in famous episodes, and in others, not less remarkable, that have not been described before. His careful descriptions need to be followed on the Staff maps, for the small maps given in the book are not of much use. Sir Arthur Conan Doyle has not said the last word about the Flanders battle, but he emphasizes its extreme severity, and the wonderful gallantry and endurance of the British and Dominion troops, who waded through quagmires to reads and defeat the enemy.
