what I had been called
to Corinth for.

When General Halleck left to assume the duties of general-in-chief I
remained in command of the district of West Tennessee. Practically I
became a department commander, because no one was assigned to that
position over me and I made my reports direct to the general-in-chief;
but I was not assigned to the position of department commander until the
25th of October. General Halleck while commanding the Department of the
Mississippi had had control as far east as a line drawn from Chattanooga
north. My district only embraced West Tennessee and Kentucky west of
the Cumberland River. Buell, with the Army of the Ohio, had, as
previously stated, been ordered east towards Chattanooga, with
instructions to repair the Memphis and Charleston railroad as he
advanced. Troops had been sent north by Halleck along the line of the
Mobile and Ohio railroad to put it in repair as far as Columbus. Other
troops were stationed on the railroad from Jackson, Tennessee, to Grand
Junction, and still others on the road west to Memphis.

The remainder of the magnificent army of 120,000 men which entered
Corinth on the 30th of May had now become so scattered that I was put
entirely on the defensive in a territory whose population was hostile to
the Union. One of the first things I had to do was to construct
fortifications at Corinth better suited to the garrison that could be
spared to man them. The structures that had been built during the
months of May and June were left as monuments to the skill of the
engineer, and others were constructed in a few days, plainer in design
but suited to the command available to defend them.

I disposed the troops belonging to the district in conformity with the
situation as rapidly as possible. The forces at Donelson, Clarksville
and Nashville, with those at Corinth and along the railroad eastward, I
regarded as sufficient for protection against any attack from the west.
The Mobile and Ohio railroad was guarded from Rienzi, south of Corinth,
to Columbus; and the Mississippi Central railroad from Jackson,
Tennessee, to Bolivar. Grand Junction and La Grange on the Memphis
railroad were abandoned.

South of the Army of the Tennessee, and confronting it, was Van Dorn,
with a sufficient force to organize a movable army of thirty-five to
forty thousand men, after being reinforced by Price from Missouri. This
movable force could be thrown against either Corinth, Boli
