Lincoln's Secret Weapon: The Telegraph

Today, we Washingtonians rely upon Twitter, smart phones, and 24-hour cable news channels to continually fill our craving for information. But a century and a half ago, during the Civil War, the only source of instantaneous news from far away was the telegraph, and in Washington, there was only one place to get it: The Department of War's headquarters building, which stood at the present site of the Eisenhower Executive Office Building, next door to the White House. 

Before the war, amazingly, the government hadn't even possessed its own telegraph operation, instead relying upon the same commercial telegraph offices that civilians used.
