How to Become a Spy: The World War II SOE Training Manual

During World War II, training in the black arts of covert operation was vital preparation for the ?ungentlemanly warfare" waged by the Special Operations Executive (SOE) against Hitler's Germany and Tojo's Japan. In the early years of the war, the SOE set up top secret training schools to instruct prospective agents in the art of being a spy. Soon there was an international network of schools in operation in secluded locations ranging from the Scottish Highlands to Singapore and Canada. Reproduced here is one of the most comprehensive training syllabi used at SOE's Special Training Schools (STSs) instructing agents on how to wreak maximum havoc in occupied Europe and beyond. A staggering array of unconventional skills are covered-from burglary, close combat, and silent killing, to utilizing propaganda, surveillance, and disguise-giving an unprecedented insight into the workings of one of WWII's most intriguing organizations. These files, released from the British National Archive, put covert history in readers' hands. Uncover an exciting, little-known part of WWII history and delve into the inner workings of a real spy network. Skyhorse Publishing, as well as our Arcade imprint, are proud to publish a broad range of books for readers interested in history--books about World War II, the Third Reich, Hitler and his henchmen, the JFK assassination, conspiracies, the American Civil War, the American Revolution, gladiators, Vikings, ancient Rome, medieval times, the old West, and much more.

Shelters, Shacks, and Shanties: The Classic Guide to Building Wilderness Shelters. D.C. Beard

This excellent hands-on guide by one of the founders of the Boy Scouts of America contains a wealth of practical instruction and advice on how to build everything from a bark teepee and a tree-top house to a log cabin and a sod house. No professional architects are needed here; and knowing how to use an axe is more important than possessing carpentry skills. More than 300 of the author's own illustrations and a clear, easy-to-follow text enable campers to create such lodgings as half-cave shelters, beaver mat huts, birch bark shacks, over-water camps, a Navajo hogan, and a pole house. Additional chapters provide information on how to use an axe, split and notch logs, make a fireplace, and even build appropriate gateways to log houses, game preserves, ranches, and other open areas. An invaluable book for scouts, campers, hikers, and hunters of all ages, this guide and its fascinating collection of outdoor lore "still has intrinsic value," said Whole Earth Magazine, and will be of keen interest to any modern homesteader.
