the fleet and army passed up the
Yazoo (which, in a great bend, sweeps: round within a few miles of
Vicksburg1) twelve miles, to Johnston's Landing, the troops debarking
at points in that vicinity along the space of three miles, without opposition.
to understand the difficulties in
Sherman's way, we must consider, for a moment, the topography of his field of intended operations.
The bluffs or hills on which
Vicksburg stands rise a little below the city, and extend northeast twelve or fifteen miles to the
Yazoo River, where they terminate in Haines's Bluff.
In the passing rear of the city the ground is high and broken, falling off gradually toward the
Big Black River, twelve
miles distant.
This, range of hills, fronting the
Mississippi and the
Yazoo, was fortified along its, entire length, and the only approach to
Vicksburg by land was up their steep faces, through which roads were cut in a manner indicated by the, engraving.
At the base of these bluffs.
Were rifle-pits.
To render the, approach still more difficult, there is a deep natural ditch, called
Chickasaw Bayou, extending from the
Yazoo, below Haines's Bluff, passing along near the base of the bluffs for some distance, and emptying into the
Mississippi.
Added to this is a deep slough, whose bottom is quicksand, and supposed to have once been a lake which stretched along the foot of the bluffs, and entered the
Bayou where the latter approached them.
These formed a natural moat in front of the fortifications, while on the plain over which
Sherman had to approach the bluffs the cypress forests were felled in places, and formed a difficult
abatis.
Sherman's army was organized in four divisions, commanded respectively by
Brigadier-Generals G. W. Morgan,
Morgan L. Smith,
A. J. Smith, and
Frederick Steele.
The first three divisions had three brigades each, and the fourth one (
Steele's), four.
In the plan of attack
