I went up to Milliken's Bend in the tug, and had a conference with the general, resulting in these orders: HEADQUARTERS DEPARTMENT OF THE TENNESSEE BEFORE 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.
