the Ninth Corps was delayed in crossing at Birdsong's. Johnston
had received timely notice of Pemberton's surrender, and was in
full retreat for Jackson. On the 8th all our troops reached the
neighborhood of Clinton, the weather fearfully hot, and water
scarce. Johnston had marched rapidly, and in retreating had caused
cattle, hogs, and sheep, to be driven into the ponds of water, and
there shot down; so that we had to haul their dead and stinking
carcasses out to use the water. On the 10th of July we had driven
the rebel army into Jackson, where it turned at bay behind the
intrenchments, which had been enlarged and strengthened since our
former visit in May. We closed our lines about Jackson; my corps
(Fifteenth) held the centre, extending from the Clinton to the
Raymond road; Ord's (Thirteenth) on the right, reaching Pearl River
below the town; and Parker's (Ninth) the left, above the town.

On the 11th we pressed close in, and shelled the town from every
direction. One of Ords brigades (Lauman's) got too close, and was
very roughly handled and driven back in disorder. General Ord
accused the commander (General Lauman) of having disregarded his
orders, and attributed to him personally the disaster and heavy
loss of men. He requested his relief, which I granted, and General
Lauman went to the rear, and never regained his division. He died
after the war, in Iowa, much respected, as before that time he had
been universally esteemed a most gallant and excellent officer.
The weather was fearfully hot, but we continued to press the siege
day and night, using our artillery pretty freely; and on the
morning of July 17th the place was found evacuated. General
Steele's division was sent in pursuit as far as Brandon (fourteen
miles), but General Johnston had carried his army safely off, and
pursuit in that hot weather would have been fatal to my command.

Reporting the fact to General Grant, he ordered me to return, to
send General Parkes's corps to Haines's Bluff, General Ord's back
to Vicksburg, and he consented that I should encamp my whole corps
near the Big Black, pretty much on the same ground we had occupied
before the movement, and with the prospect of a period of rest for
the remainder of the summer. We reached our camps on the 27th of
July.

Meantime, a division of troops, commanded by Brigadier-General W.
Sooy Smith, had been added to my corps. General Smith applied for
and received a sick-leave on the
