I doubt his getting farther this summer, if so far....
The campaign will not be pushed with any vigour during the summer.

It may be begun again in the Autumn.

Thus, so far as Trade and Cotton are concerned, we may be next Autumn, just in the situation we are now.

If the South really defeated either or both the Armies opposed to them I think it would disgust the North with the war, rather than excite them to fresh efforts.

If the armies suffer much from disease, recruiting will become difficult.
