Already the gunboats have secured the Yazoo up for twenty-three miles, to a fort on the Yazoo at Haines's Bluff, giving us a choice for a landing-place at some point up the Yazoo below this fort, or on the island which lies between Vicksburg and the present mouth of the Yazoo. (See map [b, c, d], Johnson's plantation.) But, before any actual collision with the enemy, I purpose, after our whole land force is rendezvoused at Gaines's Landing, Arkansas, to proceed in order to Milliken's Bend (a), and there dispatch a brigade, without wagons or any incumbrances whatever, to the Vicksburg & Shreveport Railroad (at h and k), to destroy that effectually, and to cut off that fruitful avenue of supply; then to proceed to the mouth of the Yazoo, and, after possessing ourselves of the latest and most authentic information from naval officers now there, to land our whole force on the Mississippi side, and then to reach the point where the Vicksburg & Jackson Railroad crosses the Big Black (f); after which to attack Vicksburg by land, while the gun-boats assail it by water.
