the disapproval of the Joint Committee of Congress on the War, and the newspaper Press had not long before announced, with affected regret, the news that he had become insane. McClernand, arriving just after Sherman's defeat near Vicksburg, fell in at once with a suggestion of his to attack the Post of Arkansas, a Confederate stronghold in the State of Arkansas and upon the river of that name, from the shelter of which Confederate gunboats had some chance of raiding the Mississippi above Vicksburg. The expedition succeeded in this early in January, 1863, and was then recalled to join Grant. This was a mortification to McClernand, who had hoped for a command independent of Grant. In his subsequent conduct he seems to have shown incapacity; he was certainly insubordinate to Grant, and he busied himself in intrigues against him, with such result as will soon be seen. As soon as Grant told the Administration that he was dissatisfied with McClernand, he was assured that he was at liberty to remove him from command. This he eventually did after some months of trial. In the first three months of 1863, while the army of the Potomac, shattered at Fredericksburg, was being prepared for the fresh attack upon Lee which ended at Chancellorsville, and while Bragg and Rosecrans lay confronting each other in Middle Tennessee, each content that the other was afraid to weaken himself by sending troops to the Mississippi, Grant was occupied in a series of enterprises apparently more cautious than that in which he eventually succeeded, but each in its turn futile. An attempt was made to render Vicksburg useless by a canal cutting across the bend of the Mississippi to the west of that fortress. Then Grant endeavoured with the able co-operation of Admiral Porter and his flotilla to secure a safe landing on the Yazoo, which enters the Mississippi a little above Vicksburg, so that he could move his army to the rear of Vicksburg by this route. Next Grant and Porter tried to establish a sure line of water communication from a point far up the Mississippi through an old canal, then somehow obstructed, into the upper waters of the Yazoo and so to a point on that river 30 or 40 miles to the north-east of Vicksburg, by which they would have turned the right of the main Confederate force; but this was frustrated by the Confederates, who succeeded in establishing a strong fort further up the Yazoo. Yet a further effort was made to establish a waterway by a canal quitting the Mississippi about 40 miles north of Vicksburg and communicating, through lakes, bayous, and smaller rivers, with its great tributary the Red River far to the south. This, like the first canal attempted, would have rendered Vicksburg useless.
