What made the American Civil War so unprecedented was that it was the first great war of the industrial era. This allowed not only greatly increased production of the materiel of war but a revolution in command and control as well. Railroads and steamboats made possible the rapid movement of large number of troops, and the telegraph enabled the entire war to be directed from Washington to Richmond in real time. When President Lincoln, on April 15, 1861, called for 75,000 volunteers after Confederate forces attacked Fort Sumter in Charleston harbor, the call reached the most distant parts of the Union states almost immediately.

Communications are even more important today, when weapons are required to be a lot smarter than the cannons of the Civil War. Remote control drones in Afghanistan and Pakistan, operated by soldiers on the ground thousands miles away from the field of action, guided by NSA intelligence collected through eavesdropping on internet and phone messages throughout the world, can deliver precision ground strikes only if they have the right information at the right time. Otherwise, they turn into expensive dumb pieces of hardware, indistinguishable in their impact from their 150-year old Civil War cousins.
