"I presume this army might advance on Manassas and ...drive them out and gratify some dissatisfied people at home and in Congress. I set the loss of life high...the rebel fortifications are no better than ours, but I have every reason to believe that they are much superior, owing to the fact that we do not anticipate an attack and they do." Capt. Wm. Medill 8th Illinois Cavalry [The estimated casualties are 21,800 killed, missing, and wounded for both sides]
