I would respectfully advise the following programs to be followed, as near as practicable, by the expedition through Yazoo Pass.
They necessarily go through the pass into Coldwater river thence down that stream into the Tallahatchie which with its junction with the Yalobusha forms the the Yazoo which it is the great object of the enterprise to enter.
At the town of Marion on the Yazoo river the enemy were said at one time to have had a battery. 1 But it has since been removed and unless a mistrust of our present design has induced the enemy to reoccupy that point no guns will be found there. It would be well to approach it carefully.
Below Marion the river divides forming a very large island, the right hand branch, descending, being known as the Big Sun Flower, or at least connecting with it, and the left hand branch retains the name of Yazoo. On this is Yazoo City where in all probability steamers will be found, and if any Gunboats are being constructed it is likely at this place.
According to the information I receive most of the transports are up the Sun Flower river. I would therefore advise that both of these streams, and in fact all navigable bayous, be well reconnoitered before the expedition returns.
The Yalobusha is a navigable stream to Grenada. At this place the rail-road branches one going to Memphis, the other to Columbus Ky. These roads cross the river on different bridges.
The enemy are now repairing boath these roads and on the upper one, the one leading through the middle of West Tennessee, have made considerable progress. I am liable at all times to
