n became necessary.

McPherson reached Clinton with the advance early on the 13th and
immediately set to work destroying the railroad. Sherman's advance
reached Raymond before the last of McPherson's command had got out of
the town. McClernand withdrew from the front of the enemy, at Edward's
station, with much skill and without loss, and reached his position for
the night in good order. On the night of the 13th, McPherson was
ordered to march at early dawn upon Jackson, only fifteen miles away.
Sherman was given the same order; but he was to move by the direct road
from Raymond to Jackson, which is south of the road McPherson was on and
does not approach within two miles of it at the point where it crossed
the line of intrenchments which, at that time, defended the city.
McClernand was ordered to move one division of his command to Clinton,
one division a few miles beyond Mississippi Springs following Sherman's
line, and a third to Raymond. He was also directed to send his siege
guns, four in number with the troops going by Mississippi Springs.
McClernand's position was an advantageous one in any event. With one
division at Clinton he was in position to reinforce McPherson, at
Jackson, rapidly if it became necessary; the division beyond Mississippi
Springs was equally available to reinforce Sherman; the one at Raymond
could take either road. He still had two other divisions farther back
now that Blair had come up, available within a day at Jackson. If this
last command should not be wanted at Jackson, they were already one
day's march from there on their way to Vicksburg and on three different
roads leading to the latter city. But the most important consideration
in my mind was to have a force confronting Pemberton if he should come
out to attack my rear. This I expected him to do; as shown further on,
he was directed by Johnston to make this very move.

I notified General Halleck that I should attack the State capital on the
14th. A courier carried the dispatch to Grand Gulf through an
unprotected country.

Sherman and McPherson communicated with each other during the night and
arranged to reach Jackson at about the same hour. It rained in torrents
during the night of the 13th and the fore part of the day of the 14th.
The roads were intolerable, and in some places on Sherman's line, where
the land was low, they were covered more than a foot deep with water.
But the troops never murmured. By nine o'clock Cro
