succeeded in driving the enemy from
position to position back toward Port Gibson steadily all day.

Osterhaus did not, however, move the enemy from the position
occupied by him on our left until Logan's division of McPherson's
corps arrived.

McClernand, who was with the right in person, sent repeated
messages to me before the arrival of Logan to send Logan's and
Quinby's divisions of McPherson's corps to him.

I had been on that as well as all other parts of the field, and
could see how they could be used there to advantage. However, as
soon as the advance of McPherson's corps (Logan's division)
arrived, I sent one brigade to McClernand on the right, and sent
one brigade, Brigadier-General J. E. Smith commanding, to the
left to the assistance of Osterhaus.

By the judicious disposition made of this brigade, under the
immediate supervision of McPherson and Logan, a position was soon
obtained giving us an advantage which soon drove the enemy from
that part of the field, to make no further stand south of Bayou
Pierre.

The enemy was here repulsed with a heavy loss in killed, wounded,
and prisoners. The repulse of the enemy on our left took place
late in the afternoon. He was pursued toward Port Gibson, but
night closing in, and the enemy making the appearance of another
stand, the troops slept upon their arms until daylight.

In the morning it was found that the enemy had retreated across
Bayou Pierre, on the Grand Gulf road, and a brigade of Logan's
division was sent to divert his attention whilst a floating
bridge was being built across Bayou Pierre immediately at Port
Gibson. This bridge was completed, eight miles marched by
McPherson's corps to the north fork of Bayou Pierre, that stream
bridged, and the advance of this corps commenced passing over it
at 5 o'clock the following morning.

On the 3d the enemy was pursued to Hawkinson's Ferry, with (p. 381)
slight skirmishing all day, during which we took quite a
number of prisoners, mostly stragglers from the enemy.

Finding that Grand Gulf had been evacuated, and that the advance
of my forces was already fifteen miles out from there, and on the
road, too, they would have to take to reach either Vicksburg,
Jackson, or any intermediate point on the railroad between the
