Immediately after the reduction of Arkansas Post and the capture of the garrison, McClernand returned with his entire force to Napoleon, at the mouth of the Arkansas River. From here I received messages from both Sherman and Admiral Porter, urging me to come and take command in person, and expressing their distrust of McClernand’s ability and fitness for so important and intricate an expedition.
On the 17th I visited McClernand and his command at Napoleon. It was here made evident to me that both the army and navy were so distrustful of McClernand’s fitness to command that, while they would do all they could to insure success, this distrust was an element of weakness. It would have been criminal to send troops under these circumstances into such danger. By this time I had received authority to relieve McClernand, or to assign any person else to the command of the river expedition, or to assume command in person. I felt great embarrassment about McClernand. He was the senior major-general after myself within the department. It would not do, with his rank and ambition, to assign a junior over him. Nothing was left, therefore, but to assume the command myself. I would have been glad to put Sherman in command, to give him an opportunity to accomplish what he had failed in the December before; but there seemed no other way out of the difficulty, for he was junior to McClernand. Sherman’s failure needs no apology.
On the 20th I ordered General McClernand with the entire command, to Young’s Point and Milliken’s Bend, while I returned to Memphis to make all the necessary preparation for leaving the territory behind me secure. General Hurlbut with the 16th corps was left in command. The Memphis and Charleston railroad was held, while the Mississippi Central was given up. Columbus was the only point between Cairo and Memphis, on the river, left with a garrison. All the troops and guns from the posts on the abandoned railroad and river were sent to the front.
