ion for private purposes. He asked to be
relieved from further duty in the capacity in which he was engaged and
his request was granted. When General Halleck took the field in April,
1862, Sheridan was assigned to duty on his staff. During the advance on
Corinth a vacancy occurred in the colonelcy of the 2d Michigan cavalry.
Governor Blair, of Michigan, telegraphed General Halleck asking him to
suggest the name of a professional soldier for the vacancy, saying he
would appoint a good man without reference to his State. Sheridan was
named; and was so conspicuously efficient that when Corinth was reached
he was assigned to command a cavalry brigade in the Army of the
Mississippi. He was in command at Booneville on the 1st of July with
two small regiments, when he was attacked by a force full three times
as numerous as his own. By very skilful manoeuvres and boldness of
attack he completely routed the enemy. For this he was made a
brigadier-general and became a conspicuous figure in the army about
Corinth. On this account I was sorry to see him leaving me. His
departure was probably fortunate, for he rendered distinguished services
in his new field.

Granger and Sheridan reached Louisville before Buell got there, and on
the night of their arrival Sheridan with his command threw up works
around the railroad station for the defence of troops as they came from
the front.

CHAPTER XXVIII.

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
