On the 26th, the expedition, under convoy of the gunboats, moved up the Yazoo, and the troops were landed at various points from the junction of Old River with the Yazoo to Johnson’s Farm, a distance of about three miles, without opposition. The distance from Vicksburg was about eight miles. A strong position, known as Haines’s Bluff, some distance above on the river, was held by the Confederate forces, and in the mean while attacked by the gunboats De Kalb, Cincinnati, Louisville, Benton and Lexington. It was the plan of General Sherman to attack Vicksburg in the rear. For this purpose he was engaged, on the 28th, in getting his forces in position. Vicksburg is situated upon a high bluff, rising nearly a hundred feet above the water. This bluff faces very nearly to the west. The Mississippi in front of Vicksburg runs in a southwesterly course. These bluffs are on its eastern bank, and run off from a point five miles below the city directly inland from the head of the bend in the Mississippi until they strike the Yazoo river, nine miles northeast of Vicksburg in a straight line, and twenty-three miles from the Mississippi by the course of the Yazoo river. The face of this bluff, throughout its length precipitous and high, furnishes a natural defence against any force attempting to get into the rear of the city from the north. Where the bluffs approach the Yazoo river the rebels had constructed formidable batteries, which prevented the passage of all manner of craft. Just above these batteries, and defended by them, they had placed a heavy raft of timber and iron in the stream, making a most effectual blockade. Thus it was impossible to flank this range of bluffs. They must be attacked, if attacked at all, full in front. Against this the enemy had guarded themselves by fortifying the entire range, from Vicksburg to Milldale, its upper extremity. These fortifications consisted of abatis in front of the bluffs to a width on the average of a mile. At the foot of the bluff they had rifle pits the entire way. Above the rifle pits, and in the face of the bluff, they had constructed batteries mounting one gun each, at short intervals all the way along. On the summit of the bluffs they had earthworks thrown up, ready to cover field artillery whenever it should be desirable to bring it into action from any of these points. Thus these entire ranges of hills were one complete, bristling fortification, dangerous to approach and difficult to capture. But, notwithstanding the dangers and difficulties in the way, our brave Western soldiers were not afraid to grapple with them, nor doubtful of their abilities to overcome them.
