ADVANCE OF VAN DORN AND PRICE--PRICE ENTERS IUKA--BATTLE OF IUKA.

At this time, September 4th, I had two divisions of the Army of the
Mississippi stationed at Corinth, Rienzi, Jacinto and Danville. There
were at Corinth also Davies' division and two brigades of McArthur's,
besides cavalry and artillery. This force constituted my left wing, of
which Rosecrans was in command. General Ord commanded the centre, from
Bethel to Humboldt on the Mobile and Ohio railroad and from Jackson to
Bolivar where the Mississippi Central is crossed by the Hatchie River.
General Sherman commanded on the right at Memphis with two of his
brigades back at Brownsville, at the crossing of the Hatchie River by
the Memphis and Ohio railroad. This made the most convenient
arrangement I could devise for concentrating all my spare forces upon
any threatened point. All the troops of the command were within
telegraphic communication of each other, except those under Sherman. By
bringing a portion of his command to Brownsville, from which point there
was a railroad and telegraph back to Memphis, communication could be had
with that part of my command within a few hours by the use of couriers.
In case it became necessary to reinforce Corinth, by this arrangement
all the troops at Bolivar, except a small guard, could be sent by rail
by the way of Jackson in less than twenty-four hours; while the troops
from Brownsville could march up to Bolivar to take their place.

enemy. I was much concerned because my first duty, after holding the
territory acquired within my command, was to prevent further reinforcing
of Bragg in Middle Tennessee. Already the Army of Northern Virginia had
defeated the army under General Pope and was invading Maryland. In the
