unremitting vigilance of the Division of Military Intelligence, which, I might add, frequently carried on its work under the most disheartening condition. Military intelligence is the term applied to all such information as may be of value to the successful prosecution of a war. The Military Intelligence Division is that branch of the General Staff which is organized to secure this information. Its field of inquiry includes the investigation of active and potential enemies, allies, and neutrals; their military, political, and economic condition; their state of mind, their secret activities at home and abroad, and their strategic and tactical plans for present or future campaigns. A well-organized intelligence service provides, moreover, for estimating and safeguarding the resources of its own country; for protecting war industries and means of transportation; for stimulating the morale of its troops and of the civil population; for frustrating enemy agents and preventing the dissemination of enemy propaganda. Thus arises the distinction between the positive and the negative aspects of the service. The former, known as Positive Intelligence, concerns itself with the collection and distribution of information. It publishes estimates of the military, economic, political, and psychological status of various countries; prints maps of enemy districts, with particular reference to fortifications, harbors, and routes of travel; deciphers intercepted messages, and translates foreign documents. The Negative Branch of the service concerns itself with the frustration of all agents, military or civil, who are consciously or unconsciously of value to the enemy. This is known as Counter-Espionage, or Negative Intelligence. It establishes a system of propaganda designed to neutralize the propaganda of the enemy; it detects and causes the arrest of spies among the troops as well as in the civil population; it censors news and information given to the public; it prevents enemy agents from entering or leaving the country, and it investigates the causes of economic disturbances and unrest.
