In
person he had his headquarters at Corinth, with the three divisions
of Hamilton, Davies, and McKean, under the immediate orders of
General Rosecrans. General Ord had succeeded to the division of
McClernand (who had also gone to Washington), and held Bolivar and
Grand Junction. I had in Memphis my own and Hurlbut's divisions,
and other smaller detachments were strung along the Memphis &
Charleston road. But the enemy's detachments could strike this
road at so many points, that no use could be made of it, and
General Grant had to employ the railroads, from Columbus, Kentucky,
to Corinth and Grand Junction, by way of Jackson, Tennessee, a
point common to both roads, and held in some force.

In the early part of September the enemy in our front manifested
great activity, feeling with cavalry at all points, and on the 13th
General Van Dorn threatened Corinth, while General Price seized the
town of Iuka, which was promptly abandoned by a small garrison
under Colonel Murphy. Price's force was about eight thousand men,
and the general impression was that he was en route for Eastport,
with the purpose to cross the Tennessee River in the direction of
Nashville, in aid of General Bragg, then in full career for
Kentucky. General Grant determined to attack him in force,
prepared to regain Corinth before Van Dorn could reach it. He had
drawn Ord to Corinth, and moved him, by Burnsville, on Iuka, by the
main road, twenty-six miles. General Grant accompanied this column
as far as Burnsville. At the same time he had dispatched Rosecrans
by roads to the south, via Jacinto, with orders to approach Iuka by
the two main roads, coming into Iuka from the south, viz., they
Jacinto and Fulton roads.

On the 18th General Ord encountered the enemy about four miles out
of Iuka. His orders contemplated that he should not make a serious
attack, until Rosecrans had gained his position on the south; but,
as usual, Rosecrans had encountered difficulties in the confusion
of roads, his head of column did not reach the vicinity of Iuka
till 4 p.m. of the 19th, and then his troops were long drawn out
on the single Jacinto road, leaving the Fulton road clear for
Price's use. Price perceived his advantage, and attacked with
vehemence the head of Rosecrans's column, Hamilton's division,
beating it back, capturing a battery, and killing and disabling
seven hundred and thirty-six men, so that when night closed in
Rosecrans was driven to the
