"During the last 30 years, the Army has placed renewed emphasis on the use of staff rides to battlefields as a means to acquaint military personnel with the lessons learned of the past. It is easy to forget what one reads; one never forgets what one sees. Those of us who live and serve in the Washington, DC area have the privilege of visiting many of these national parks such as Gettysburg and Yorktown. As members of the US Army Intelligence and Security Command (INSCOM), we are particularly interested in the role played by intelligence; how the presence or lack of military intelligence made the difference between victory and defeat on the battlefield. However, one does not have to travel to a battlefield to be reminded of the history of military intelligence. It surrounds us during our daily comings and goings. This booklet has been prepared to serve as a reminder of some of these locations. The sites selected span two centuries of military intelligence in support of the Nation and its Anny, starting with George Washington in the Revolutionary War and ending with William F. Friedman in World War 11. History is not words in a dusty book; it is alive. Next time you find yourself on the corner of Constitution and 17th North West, imagine the date 5 December 1941. If you look carefully, you can see the courier exiting the War Department Munitions Building across the street and making his way, past you, to the White House."
