It was in January the troops took their position opposite Vicksburg. The water was very high and the rains were incessant. There seemed no possibility of a land movement before the end of March or later, and it would not do to lie idle all this time. The effect would be demoralizing to the troops and injurious to their health. Friends in the North would have grown more and more discouraged, and enemies in the same section more and more insolent in their gibes and denunciation of the cause and those engaged in it.
I always admired the South, as bad as I thought their cause, for the boldness with which they silenced all opposition and all croaking, by press or by individuals, within their control. War at all times, whether a civil war between sections of a common country or between nations, ought to be avoided, if possible with honor. But, once entered into, it is too much for human nature to tolerate an enemy within their ranks to give aid and comfort to the armies of the opposing section or nation.
Vicksburg, as stated before, is on the first high land coming to the river's edge, below that on which Memphis stands. The bluff, or high land, follows the left bank of the Yazoo for some distance and continues in a southerly direction to the Mississippi River, thence it runs along the Mississippi to Warrenton, six miles below. The Yazoo River leaves the high land a short distance below Haines' Bluff and empties into the Mississippi nine miles above Vicksburg. Vicksburg is built on this high land where the Mississippi washes the base of the hill. Haines' Bluff, eleven miles from Vicksburg, on the Yazoo River, was strongly fortified. The whole distance from there to Vicksburg and thence to Warrenton was also intrenched, with batteries at suitable distances and rifle-pits connecting them.
From Young's Point the Mississippi turns in a north-easterly direction to a point just above the city, when it again turns and runs south-westerly, leaving vessels, which might attempt to run the blockade, exposed to the fire of batteries six miles below the city before they were in range of the upper batteries. Since then the river has made a cut-off, leaving what was the peninsula in front of the city, an island. North of the Yazoo was all a marsh, heavily timbered, cut up with bayous, and much overflowed. A front attack was therefore impossible, and was never contemplated; certainly not by me. The problem then became, how to secure a landing on high ground east of the Mississippi without an apparent retreat. Then commenced a series of experiments to consume time, and to divert the attention of the enemy, of my troops and of the public generally. I, myself, never felt great confidence that any of the experiments resorted to would prove successful. Nevertheless I was always prepared to take advantage of them in case they did.
In 1862 General Thomas Williams had come up from New Orleans and cut a ditch ten or twelve feet wide and about as deep, straight across from Young's Point to the river below. The distance across was a little over a mile. It was Williams' expectation that when the river rose it would cut a navigable channel through; but the canal started in an eddy from both ends, and, of course, it only filled up with water on the rise without doing any execution in the way of cutting. Mr. Lincoln had navigated the Mississippi in his younger days and understood well its tendency to change its channel, in places, from time to time. He set much store accordingly by this canal. General McClernand had been, therefore, directed before I went to Young's Point to push the work of widening and deepening this canal. After my arrival the work was diligently pushed with about 4,000 men—as many as could be used to advantage—until interrupted by a sudden rise in the river that broke a dam at the upper end, which had been put there to keep the water out until the excavation was completed. This was on the 8th of March.
Even if the canal had proven a success, so far as to be navigable for steamers, it could not have been of much advantage to us. It runs in a direction almost perpendicular to the line of bluffs on the opposite side, or east bank, of the river. As soon as the enemy discovered what we were doing he established a battery commanding the canal throughout its length. This battery soon drove out our dredges, two in number, which were doing the work of thousands of men. Had the canal been completed it might have proven of some use in running transports through, under the cover of night, to use below; but they would yet have to run batteries, though for a much shorter distance.
While this work was progressing we were busy in other directions, trying to find an available landing on high ground on the east bank of the river, or to make water-ways to get below the city, avoiding the batteries.
On the 30th of January, the day after my arrival at the front, I ordered General McPherson, stationed with his corps at Lake Providence, to cut the levee at that point. If successful in opening a channel for navigation by this route, it would carry us to the Mississippi River through the mouth of the Red River, just above Port Hudson and four hundred miles below Vicksburg by the river.
Lake Providence is a part of the old bed of the Mississippi, about a mile from the present channel. It is six miles long and has its outlet through Bayou Baxter, Bayou Macon, and the Tensas, Washita and Red Rivers. The last three are navigable streams at all seasons. Bayous Baxter and Macon are narrow and tortuous, and the banks are covered with dense forests overhanging the channel. They were also filled with fallen timber, the accumulation of years. The land along the Mississippi River, from Memphis down, is in all instances highest next to the river, except where the river washes the bluffs which form the boundary of the valley through which it winds. Bayou Baxter, as it reaches lower land, begins to spread out and disappears entirely in a cypress swamp before it reaches the Macon. There was about two feet of water in this swamp at the time. To get through it, even with vessels of the lightest draft, it was necessary to clear off a belt of heavy timber wide enough to make a passage way. As the trees would have to be cut close to the bottom—under water—it was an undertaking of great magnitude.
On the 4th of February I visited General McPherson, and remained with him several days. The work had not progressed so far as to admit the water from the river into the lake, but the troops had succeeded in drawing a small steamer, of probably not over thirty tons' capacity, from the river into the lake. With this we were able to explore the lake and bayou as far as cleared. I saw then that there was scarcely a chance of this ever becoming a practicable route for moving troops through an enemy's country. The distance from Lake Providence to the point where vessels going by that route would enter the Mississippi again, is about four hundred and seventy miles by the main river. The distance would probably be greater by the tortuous bayous through which this new route would carry us. The enemy held Port Hudson, below where the Red River debouches, and all the Mississippi above to Vicksburg. The Red River, Washita and Tensas were, as has been said, all navigable streams, on which the enemy could throw small bodies of men to obstruct our passage and pick off our troops with their sharpshooters. I let the work go on, believing employment was better than idleness for the men. Then, too, it served as a cover for other efforts which gave a better prospect of success. This work was abandoned after the canal proved a failure.
