RE VICKSBURG, March 16, 1863

Major-General W. T. SHERMAN, commanding Fifteenth Army Corps.

GENERAL: You will proceed as early as practicable up Steele's
Bayou, and through Black Bayou to Deer Creek, and thence with the
gunboats now there by any route they may take to get into the Yazoo
River, for the purpose of determining the feasibility of getting an
army through that route to the east bank of that river, and at a
point from which they can act advantageously against Vicksburg.

Make such details from your army corps as may be required to clear
out the channel of the various bayous through which transports
would have to ran, and to hold such points as in your judgment
should be occupied.

I place at your disposal to-day the steamers Diligent and Silver
Wave, the only two suitable for the present navigation of this
route. Others will be supplied you as fast as required, and they
can be got.

I have given directions (and you may repeat them) that the party
going on board the steamer Diligent push on until they reach Black
Bayou, only stopping sufficiently long at any point before reaching
there to remove such obstructions as prevent their own progress.
Captain Kossak, of the Engineers, will go with this party. The
other boat-load will commence their work in Steele's Bayou, and
make the navigation as free as possible all the way through.

There is but little work to be done in Steele's Bayou, except for
about five miles abort midway of the bayou. In this portion many
overhanging trees will have to be removed, and should be dragged
out of the channel.

Very respectfully,

U. S. GRANT, Major-General.

On returning to my camp at Young's Point, I started these two boats
up the Yazoo and Steele's Bayou, with the Eighth Missouri and some
pioneers, with axes, saws, and all the tools necessary. I gave
orders for a part of Stuart's division to proceed in the large
boats up the Mississippi River to a point at Gwin's plantation,
where a bend of Steele's Bayou neared the main river; and the next
day, with one or two stag-officers and orderlies, got a navy-tug,
and hurried up to overtake Admiral Porter. About sixty miles up
Steele's Bayou we came to the gunboat Price, Lieutenant Woodworth,
United States Navy; commanding, and then turned into Black Bayou, a
narrow, crooked channel, obstructed by overhanging oaks, and filled
with cypress and cotton-wood trees. The gunboats had forced their
way through, pushing asi
