Vicksburg: Grant Changes Strategy

April 1, 1863 – Major General Ulysses S. Grant finally conceded the impossibility of capturing Vicksburg from the north and began devising another, more daring, plan.

By this time, Grant had failed or was on the verge of failing in five efforts to reach Vicksburg:

  • Overland via the Mississippi Central Railroad
  • On water via Chickasaw Bayou
  • On water via various canal projects
  • On water via Steele’s Bayou
  • On water via Yazoo Pass

Rear Admiral David D. Porter brought Grant and Major General William T. Sherman, Grant’s most trusted subordinate, on a reconnaissance mission. They boarded the U.S.S. Tuscumbia and steamed up the Yazoo River to Haynes’s Bluff, where Confederates had placed batteries north of Vicksburg. Grant went on this mission figuring he would have “to collect all my strength and attack Haynes’ Bluff.” Understanding that such an effort would involve heavy loss, Grant nonetheless stated, “I think it can be done.”

As the Tuscumbia approached, Grant observed the enemy batteries in the heights above. He also noted the natural obstacles and enemy torpedoes that could sink naval vessels. Grant wrote Porter the next day, “After the reconnaissance of yesterday, I am satisfied that an attack upon Haynes’ Bluff would be attended with immense sacrifice of life, if not with defeat. This, then, closes out the last hope of turning the enemy by the right (north).”

Grant had been working on another plan to operate on the other side of the Mississippi River from Vicksburg. This involved moving Federal troops from Milliken’s Bend, above Vicksburg, to New Carthage below. But Grant meant for this operation to support Major General Nathaniel P. Banks’s advance on Port Hudson, not to take Vicksburg. Grant feared that this operation could take months or until the Lincoln administration lost patience and called it off.

After seeing that attacking Haynes’s Bluff would be futile, Grant started reworking the Milliken’s Bend plan to take Vicksburg rather than support Banks. Grant wrote, “I have sent troops through from Milliken’s Bend to New Carthage, to garrison and hold the whole route and make the wagon road good.”

From New Carthage, Federals could cross the Mississippi and attack either Grand Gulf or Warrenton, which guarded the back door to Vicksburg from the south. Grant wrote, “It is important to prevent the enemy from further fortifying either of these places. I am satisfied that one army corps, with the aid of two gunboats, can take and hold Grand Gulf until such time as I might be able to get my whole army there and make provision for supplying them.”

The troops currently at Milliken’s Bend belonged to XIII Corps under Major General John A. McClernand. They were in the process of clearing the path for men and supplies to move to New Carthage. McClernand reported to Grant, “I am now repairing the roads and bridges between here and Richmond, a distance of 12 miles, including a floating bridge of 200 feet in length, and will soon commence repairing the road from that place to (New) Carthage, and constructing barges to ply between the same places, unless stopped by unknown obstacles.”

Grant and McClernand had never gotten along; Grant was a West Pointer and McClernand was a former politician with connections going all the way up to President Abraham Lincoln. When Grant asked McClernand to detach some of his troops to dig a levee, McClernand replied:

“I think it probable that you would not have ordered it with a fuller knowledge of my operations… the prospect so far is quite encouraging… and I hope you will find it consistent with your general views to leave me to prosecute my present undertaking with all the resources at my disposal.”

Porter disagreed with Grant’s plan to march the army down the west bank of the Mississippi. He believed Grant should pull his army back to Memphis and march overland along the Mississippi Central Railroad to Vicksburg as he had tried in December. But the northern public and the administration would view this as yet another defeat, which could be detrimental to the careers of all involved.

Grant met with Porter on the 2nd and described the plan in greater detail:

  • Sherman’s corps would feign an attack on Haynes’s Bluff as a diversion
  • Grant’s remaining two corps would move from Milliken’s Bend to New Carthage, building roads during the march
  • Porter’s fleet would pass the Vicksburg batteries with gunboats, transports, and supply vessels, and meet Grant’s troops at Hard Times, 30 miles south of the city
  • The ships would ferry the troops to the east bank of the Mississippi, where Grant would advance on Vicksburg from the south

Porter still expressed reluctance, warning Grant that “when these gunboats once go below we give up all hopes of ever getting them up again.” But Navy Secretary Gideon Welles urged Porter to cooperate, writing that if the operation succeeded, it would be “the severest blow that can be struck upon the enemy,” and thus “worth all the risk.”

On the Confederate side, Lieutenant General John C. Pemberton, commanding the Department of Mississippi and East Louisiana, endured not only mounting Federal threats to Vicksburg, but mounting criticism of his abilities as well. President Jefferson Davis defended Pemberton, writing that “by his judicious imposition of his forces and skillful selection of the best points of defence he has repulsed the enemy at Vicksburg, Port Hudson, on the Tallahatchie and at Deer Creek, and has thus far foiled his every attempt to get possession of the Mississippi river and the vast section of country which it controls.”

Pemberton had requested reinforcements from General Joseph E. Johnston, commanding the Confederate Western Department. Pemberton specifically wanted Major General Earl Van Dorn’s cavalry operating in western Tennessee. But Johnston replied:

“In the present aspect of affairs, General Van Dorn’s cavalry is much more needed in this department than in that of Mississippi and East Louisiana, and can not be sent back as long as this state of things exists. You have now in your department five brigades of the troops you most require, viz., infantry, belonging to the Army of Tennessee. This is more than a compensation for the absence of General Van Dorn’s cavalry command.”
