Breckinridge is at Jackson. Johnston has 40,000 at Canton. From all I can gather, Walker's command is all between Yazoo and Big Black, I leave to-day for Haynes' Bluff.

Very respectfully,

SATARTIA, MISS,

June 6, 1863.

COLONEL: There is in front of me a large force, of which I cannot ascertain the exact amount, but which is not less than 15,000 and in view of the fact that the river is falling rapidly, and gunboats will soon be unable to recross the bar below, I shall to-day move toward Haynes' Bluff STARTING AS soon as I can get ready.

I have the honor to be, very respectfully your obedient servant,

NATHAN KIMBALL,

Brigadier-General Commanding.
