n the morning (16th) two men, who had been employed
on the Jackson and Vicksburg railroad, were brought to me. They
reported that they had passed through Pemberton's army in the night, and
that it was still marching east. They reported him to have eighty
regiments of infantry and ten batteries; in all, about twenty-five
thousand men.

I had expected to leave Sherman at Jackson another day in order to
complete his work; but getting the above information I sent him orders
to move with all dispatch to Bolton, and to put one division with an
ammunition train on the road at once, with directions to its commander
to march with all possible speed until he came up to our rear. Within
an hour after receiving this order Steele's division was on the road.
At the same time I dispatched to Blair, who was near Auburn, to move
with all speed to Edward's station. McClernand was directed to embrace
Blair in his command for the present. Blair's division was a part of
the 15th army corps (Sherman's); but as it was on its way to join its
corps, it naturally struck our left first, now that we had faced about
and were moving west. The 15th corps, when it got up, would be on our
extreme right. McPherson was directed to get his trains out of the way
of the troops, and to follow Hovey's division as closely as possible.
McClernand had two roads about three miles apart, converging at Edward's
station, over which to march his troops. Hovey's division of his corps
had the advance on a third road (the Clinton) still farther north.
McClernand was directed to move Blair's and A. J. Smith's divisions by
the southernmost of these roads, and Osterhaus and Carr by the middle
road. Orders were to move cautiously with skirmishers to the front to
feel for the enemy.

Smith's division on the most southern road was the first to encounter
the enemy's pickets, who were speedily driven in. Osterhaus, on the
middle road, hearing the firing, pushed his skirmishers forward, found
the enemy's pickets and forced them back to the main line. About the
same time Hovey encountered the enemy on the northern or direct wagon
road from Jackson to Vicksburg. McPherson was hastening up to join
Hovey, but was embarrassed by Hovey's trains occupying the roads. I was
still back at Clinton. McPherson sent me word of the situation, and
expressed the wish that I was up. By half-past seven I was on the road
and proceeded rapidly to the front, ordering all trains that were
