Federals and Confederates Maneuver in Mississippi

October 16, 1862 – Confederates reorganized their command structure in Mississippi, Major General Ulysses S. Grant was given new Federal responsibilities, and a secret mission to capture Vicksburg was concocted.

Following the Battle of Corinth, Major General Earl Van Dorn, commanding the Confederate Army of the West, was brought before a court of inquiry to answer charges that he had been responsible for the defeat. The charges were later dropped, but the Confederate high command no longer entrusted Van Dorn to lead an army.

Under Adjutant General Samuel Cooper’s Special Orders No. 73, “The State of Mississippi and that part of Louisiana east of the Mississippi River is constituted a separate military department.” This disbanded Van Dorn’s District of Mississippi under General Braxton Bragg and created a new department independent from Bragg’s.

The new commander was Lieutenant General John C. Pemberton, a Pennsylvanian who married a Virginian. Pemberton was to “consider the successful defense of those States as the first and chief object of your command.” This especially included Vicksburg and Port Hudson, the Confederacy’s last two major strongholds on the Mississippi River. Other points included New Orleans and Corinth (under Federal occupation), Baton Rouge, and all contested areas in Mississippi.

Pemberton set up headquarters at Jackson, Mississippi, where he divided the department into three districts:

  • Brigadier General Daniel Ruggles commanded District 1 from Jackson
  • Brigadier General Martin L. Smith commanded District 2 from Vicksburg
  • Brigadier General William N.R. Beall commanded District 3 from Port Hudson

On the Federal side, Adjutant General Lorenzo Thomas announced that Major General Ulysses S. Grant would command the new Department of the Tennessee. General Order No. 168 designated all Federal troops within this new department as Federal XIII Corps. This included not only the Armies of the Tennessee and the Mississippi already under his command, but the area from Cairo, Illinois, to northern Mississippi west of the Tennessee River.

Grant soon concentrated all Federal troops in his jurisdiction into a revised Army of the Tennessee. He then urged General-in-Chief Henry W. Halleck to allow him to go beyond just guarding railroads and supply depots by launching an offensive against Vicksburg.

The problem with moving on Vicksburg was that it required support from Federals on the west bank of the Mississippi, which was outside Grant’s jurisdiction. Grant would have to cooperate with Major General Samuel R. Curtis, who commanded the west side, but Grant cited instances in which Curtis had refused. Therefore, Grant wrote, “I would respectfully suggest that both banks of the river be under one command.”

Unbeknownst to Grant, a campaign to capture Vicksburg had already been clandestinely approved. Major General John A. McClernand, Grant’s former subordinate, had lobbied his friend President Abraham Lincoln for an independent command. McClernand had been an influential Democratic politician in Illinois before the war, and he assured Lincoln that he could persuade fellow Democrats to support a campaign against Vicksburg because it would open the Mississippi for Illinois shipping to reach the Gulf of Mexico.

Lincoln approved, with Secretary of War Edwin M. Stanton issuing secret orders for McClernand “to proceed to the States of Indiana, Illinois, and Iowa, and to organize the troops remaining in those States and to be raised by volunteering or draft… to the end that, when a sufficient force not required by the operations of General Grant’s command shall be raised, an expedition may be organized under General McClernand’s command against Vicksburg and to clear the Mississippi River and open navigation to New Orleans.”

The order also directed McClernand to show this document “to Governors, and even others, when in his discretion he believes so doing to be indispensable to the progress of the expedition.” Based on these orders, McClernand considered himself leading a command fully autonomous from Grant.

Thus, McClernand began recruiting a new “Army of the Mississippi” while Grant began assembling a force of 30,000 Federals at Grand Junction, Tennessee. Both forces had the same objective, which would seriously complicate upcoming Federal operations.
