My dear General,
I do not believe you appreciate the magnitude of the misfortune involved in Lee's escape. He was within our easy grasp, and to have closed upon him would, in connection with our other late successes, have ended the war. As it is, the war will be prolonged indefinitely. If you could not safely attack Lee last Monday, how can you possibly do so south of the river, when you can take with you very few -- no more than two-thirds of the force you then had in hand? It would be unreasonable to expect and I do not expect that you can now effect much. Your golden opportunity is gone, and I am distressed immeasurably because of it.
