eve him from duty that very day.

At the close of the operations just described my force, in round
numbers, was 48,500. Of these 4,800 were in Kentucky and Illinois,
7,000 in Memphis, 19,200 from Mound City south, and 17,500 at Corinth.
General McClernand had been authorized from Washington to go north and
organize troops to be used in opening the Mississippi. These new levies
with other reinforcements now began to come in.

On the 25th of October I was placed in command of the Department of the
Tennessee. Reinforcements continued to come from the north and by the
2d of November I was prepared to take the initiative. This was a great
relief after the two and a half months of continued defence over a large
district of country, and where nearly every citizen was an enemy ready
to give information of our every move. I have described very
imperfectly a few of the battles and skirmishes that took place during
this time. To describe all would take more space than I can allot to
the purpose; to make special mention of all the officers and troops who
distinguished themselves, would take a volume. (*9)

CHAPTER XXX.

THE CAMPAIGN AGAINST VICKSBURG--EMPLOYING THE FREEDMEN--OCCUPATION OF
HOLLY SPRINGS--SHERMAN ORDERED TO MEMPHIS--SHERMAN'S MOVEMENTS DOWN THE
MISSISSIPPI--VAN DORN CAPTURES HOLLY SPRINGS--COLLECTING FORAGE AND
FOOD.

Vicksburg was important to the enemy because it occupied the first high
ground coming close to the river below Memphis. From there a railroad
runs east, connecting with other roads leading to all points of the
Southern States. A railroad also starts from the opposite side of the
river, extending west as far as Shreveport, Louisiana. Vicksburg was
the only channel, at the time of the events of which this chapter
treats, connecting the parts of the Confederacy divided by the
Mississippi. So long as it was held by the enemy, the free navigation
of the river was prevented. Hence its importance. Points on the river
between Vicksburg and Port Hudson were held as dependencies; but their
fall was sure to follow the capture of the former place.

The campaign against Vicksburg commenced on the 2d of November as
indicated in a dispatch to the general-in-chief in the following words:
"I have commenced a movement on Grand Junction, with three divisions
from Corinth and two from Bolivar. Will leave here [Jackson, Tennessee]
to-morrow, and take command in person. If found practicable, I will go
