The Countess Mountbatten's Own Legion of Frontiersmen was conceived and organized in 1905 as a body of frontier sentinels, and they first published The Frontiersman's Pocket-Book in 1909 as their training and survival manual. Compiled and edited by Roger Pocock (1865-1941), founder of the Frontiersmen. The Frontiersman's Pocket-Book remains a useful, if dated, guide to living and working in the bush, as well as covering how to conduct guerrilla warfare. Covers topics such as pathfinding, water, food, fire, camps and expeditions, means of travel from horses to boats to motor cars, training (such as scouting and reconnaissance, signals, and shooting), morale, and medical and surgical treatment.
