3. Persistence Grant’s Failed Attempts from Dec 1862 to Apr 1863

4. Grant’s Failed Attempts • Terrain • Chickasaw Bayou • Grant’s Canal • Lake Providence • Yazoo Pass • Steele’s Bayou • Results

5. Vicksburg and the Mississippi • The last Confederate post on the river • Key to New Orleans • Control of the Mississippi River would provide a safe route for the transportation of troops and supplies. • Impassable batteries • Vicksburg was situated on high bluffs overlooking the Mississippi River. A five mile stretch of artillery batteries protected the city from invaders.

6. Vicksburg and the Mississippi • Surrounding terrain • The Delta to the north and the Louisiana lowlands to the east • Swampy land covered with thick forests and dense undergrowth containing numerous rivers, lakes and bayous subject to constant floods. • Swamps south of Vicksburg • Flooded swamplands prevented ground movement.

7. Vicksburg and the Mississippi • As Union forces moved south towards Vicksburg, the winter and the wet season began. • This ended all possibilities of moving forces by land. • Grant was forced to find an alternative route to reach Vicksburg. • Made several failed attempts from Dec 1862 to April 1863 • Serve as a lesson about perseverance

8. Grant’s First Attempt:Chickasaw Bayou Dec 1862 • A frontal attack by William Sherman against Chickasaw Bluffs, just a few miles north of Vicksburg • Severely repulsed • Confederate cavalry raids by Van Dorn and Forrest show Grant the vulnerability of his logistics

9. Grant’s CanalJan-Mar 1863 • After the repulse at Chickasaw Bayou, Sherman briefly considered an attack against Snyder’s Bluff, but cancelled it due to fog • In Jan, Grant moved his army into camps at Milliken’s Bend and Young’s Point on the Mississippi • His objective was to reach the high ground east of the Mississippi floodplain Milliken’s Bend

10. Grant’s CanalJan-Mar 1863 • An effort to dig a canal across the De Soto Peninsula and bypass the Vicksburg defenses • Confederates built batteries commanding the length of the canal • Work on the canal essentially stopped on Mar 24 • When the river receded in Apr, the canal drained out • By April 4, it was dry

11. Grant’s CanalJan-Mar 1863 Grant’s Canal as it appears today in Delta, LA

12. Lake Providence Feb-Mar 1863 • On Feb 3, while work on Grant’s Canal was still in progress, Federal troops cut a short canal from the Mississippi to Lake Providence, hoping to tie into a maze of bayous to gain access to the Red River • In early March, Grant personally examined the route and reported that “there was scarcely a chance of this ever becoming a practicable route for moving troops through an enemy’s country” Red River

13. Yazoo Pass Feb-Apr 1863 • Federal engineers blasted a hole in the levee that separated the Mississippi River from the Yazoo River, about ten miles below Helena, Arkansas and 325 miles north of Vicksburg • This would allow troop transports to enter the Tallahatchie River • Confederate defenses at Fort Pemberton halted the transports

14. Steele’s Bayou • Admiral Porter tried to force 11 through a heavily obstructed 200 mile route up Steele’s Bayou with Sherman following on foot • The Confederates blocked the boats at Rolling Fork and Sherman arrived just in the nick of time to save Porter from destruction

15. Summary of Failed Attempts • While Grant was prepared to capitalize on success, he claimed he never really had any hopes for these preliminary attempts • His main purposes were to • Keep the offensive spirit alive • Satisfy the public demand for action • Keep the enemy guessing • Buy time until the weather permitted a wide envelopment of Vicksburg from the south

16. Public Criticism • To the northern public such purposes were not as readily apparent • “The people of the East, knowing about as much of the geography of the region of Grant’s meanderings as they did of Japan, were utterly bewildered by the fragmentary and mixed-up newspaper telegrams about Lake Providence, Moon Lake, Steele’s Bayou, Williams’ Cut-Off, the Yazoo, the Yallabusha, the Tallahatchie…. They only knew that months dragged wearily by… that the soldiers were reported dying from disease… The country was heartsick for victory.” • Albert Richardson, New York Tribune

17. Discussion Question • How do leaders handle repeated failures in their units? • A company commander wants to raise his unit’s APFT average. • He centralizes the PT program. • He decentralizes the PT program. • He incorporates rewards. • He incorporates punishments. • He focuses on running. • He focuses on strength. • Every month the APFT scores stay the same. What does he do?

18. Cooperation Grant, Porter, and Joint Operations

19. New Plan • On March 29, with the failure of the winter attempts and the promise of better spring weather, Grant decided to march his army down the west side of the Mississippi to a point below Vicksburg where river transports could ferry the men across • To make this work, the transports would have to run past the gauntlet of the Vicksburg batteries

20. The Federal Army • Ulysses Grant’s Army of the Tennessee • Hurlbut- XVI Corps (headquartered in Memphis, largely performing rear area missions) • Sherman- XV Corps • McPherson- XVII Corps • McClernand- XIII Corps • Maneuver force of ten divisions (44,000 effectives)

21. The Federal Navy • Mississippi River Squadron commanded by Flag Officer David Porter • About 60 combat vessels of which 20 to 25 could support the Vicksburg operation at any one time • 13 ironclads

22. Joint Operations • Operations carried on by two or more of the armed forces • At Vicksburg, this was the Army and the Navy

23. Grant and Porter’s Relationship • Porter reported to the Navy Department in Washington rather than to Grant • Neither Grant nor Porter had the authority to act as a joint commander and direct the combined efforts of the Army and the Navy • Instead Grant and Porter would have to cooperate with each other in order to achieve unity of effort

24. Unity of Command All forces operate under one responsible commander who possesses requisite authority to direct forces in pursuit of a common unified purpose Unity of Effort Coordination and cooperation among all forces, not necessarily part of the same command structure toward a commonly recognized objective Unity of Command vs. Unity of Effort

25. Grant’s Approach to Unity of Effort • Grant worked hard to ensure the good relations, constant communication, and division of labor necessary to achieve unity of effort • “I had had in contemplation the whole winter the movement by land to a point below Vicksburg from which to operate– my recollection was that Admiral Porter was the first one to whom I mentioned it. The cooperation of the Navy was absolutely essential to the success (even to the contemplation) of such an enterprise.” • Ulysses Grant

26. Joint Operations in the Vicksburg Campaign • Running the Gauntlet • Grand Gulf • Bruinsburg • Siege • Logistics “Running the Gauntlet At Vicksburg” by Don Stivers.Admiral Porter's fleet steams past the Confederate batteries at Vicksburg.

27. Running the Gauntlet • Grant decided to shift Porter’s fleet to the south of Vicksburg • Once in place they could protect and transport any troops Grant moved there • First however, Porter would have to make it past the Vicksburg batteries

28. Running the Gauntlet • On the night of April 16, Porter led seven gunboats followed by three transports loaded with thousands of men • The transports towed ten barges loaded with coal and ammunition to be used in future operations down river • The Confederate batteries observed the flotilla, lit up the river with flares, and opened up with their cannon • Only one ship was lost • On the 26th Grant ran the gauntlet again with six more transports laden with coal and rations

29. Grand Gulf • While Porter was moving by river, the army was moving south by land down the west side of the Mississippi • Across the river from Hard Times was the Confederate defensive position at Grand Gulf • Grant had a truly joint plan for Grand Gulf • Porter and the navy would silence the Confederate batteries followed by rapid landings by McClernand’s Corps to seize the fortifications and secure a foothold for the rest of the army

30. Grand Gulf: April 29, 1863 • Porter’s ironclads opened fire on Grand Gulf but could not defeat it • Porter declared, “Grand Gulf is the strongest place on the Mississippi.” • Grant stopped the operation and decided to try a different landing site View from Fort Cobun

31. Bruinsburg • After consulting Porter, Grant decided to run the fleet past Grand Gulf while McClernand marched his force past along a concealed route • By dawn the army and navy were at Bruinsburg where Porter ferried the army across the river without opposition • By May 6, more than 33,000 troops had made the crossing • Grant now was on the east side of the Mississippi River, south of Vicksburg • His cooperation with Porter is what made this possible

32. Discussion Question • How do we train soldiers to build unity of effort in Iraq? • A platoon leader has to deal with • Local government officials • Religious and community leaders • Other US military units • Iraqi security forces • NGOs • State Department officials • What does he do?

33. Calculated Risk Grant and Logistics

34. The Challenge • Once Grant was across the Mississippi, he had a decision to make • The principal difficulty in any campaign against Vicksburg remained logistical • This point had been driven home to Grant in Dec 1862 when Van Dorn’s cavalry destroyed Grant’s advanced depot at Holly Springs and Forrest conducted a raid on the important railroad junction in Jackson, TN

35. Logistics Vulnerabilities • The twin raids wrecked Grant’s plan for an overland, railroad-centered attack to support Sherman’s Chickasaw Bayou expedition • It also forced Grant to rely on foraging and requisition in the surrounding countryside to feed his army in the weeks surrounding the raid • This showed Grant that the Mississippi Valley, though relatively underpopulated, was agriculturally rich in beef, hogs, and grain • He now decided to change his plan

36. The Solution • “Up to this time my intention had been to secure Grand Gulf, as a base of supplies, detach McClernand’s corps to Banks and cooperate with him in the reduction of Port Hudson.” • Now Grant “determined to move independently of Banks, cut loose from my base, destroy the rebel force in rear of Vicksburg or invest or capture the city.” • Grant, Memoirs Crossing at Bruinsburg placed Grant between Vicksburg and Port Hudson, LA which was being threatened by Federal General Banks

37. Grant “Cuts Loose” • When Grant says he “cut loose” from his line of supply he somewhat exaggerates • He still had a strong system that brought wagons from Young’s Point to Bower’s Landing where the supplies were loaded on steamboats and carried to Grand Gulf • From Grand Gulf huge wagons escorted by brigades brought the supplies forward to the main force Winslow Homer print of Civil War wagon train

38. “Convoy Operations” • So really what Grant meant by “cutting loose” was that he did not occupy and garrison the supply route • Instead he conducted something similar to today’s convoy resupply system

39. Grant “Cuts Loose” • Grant continued to use wagon trains for war materiel (weapons, ammunition, medical supplies, etc) and some limited food items like coffee and bread • The countryside however would sustain his army with bulky animal forage, meat, and other provisions The “forage cap,” as the name suggests, was used not only as a hat but also as a “bag” to put vegetables, eggs, etc. in while foraging during a campaign.

40. Grant “Cuts Loose” • “We started from Bruinsburg with an average of about two days’ rations, and received no more from our supplies for some days; abundance was found in the meantime.” • Grant, Memoirs • To survive in a foraging environment, speed would be essential • Had to keep moving to avoid exhausting local supplies • Grant wrote Sherman, “I believe we can be in Vicksburg in seven days.”

41. Effect on Pemberton • Grant’s efforts to move south had left him with two well-stocked advance depots • One below Vicksburg and several just above it • As Grant moved away from his new base at Grand Gulf, Pemberton expected him to stay close to the river to take advantage of these depots • Grant’s move inland caught Pemberton by surprise

42. Discussion Question • What’s the difference between a risk and a gamble? • The most likely population course of action is to comply with US directives. The most dangerous COA is for them to resist using guerrilla type tactics. • How do you mitigate the risk?

43. The Peter Principle and Frame of Reference John Pemberton

44. John Pemberton • John Pemberton was a northerner (born in Pennsylvania) whose association with the South was by marriage • When he resigned from the US Army on Apr 24, 1861 he was only a captain • In the Confederate Army he experienced a meteoric and seemingly unwarranted rise to brigadier general on June 17, 1861.

45. John Pemberton • In February, 1862, he was appointed major general and placed in command of South Carolina, Georgia and Florida. • In this capacity he demonstrated an unsuitability for the pressures of high command and a thoroughly bureaucratic approach to his duties • He also learned the importance of defending a fixed location, Charleston, and developed a defensive strategic approach Fort Pemberton was built to deny Union gunboats access to the Stono River as it approached Charleston

46. John Pemberton • In spite of mixed results in Charleston and not gaining any useful experience in field or combat command, six months later Pemberton was made lieutenant general and given command over the Department of Mississippi and East Louisiana • Commanded five divisions totaling 43,000 effectives

47. John Pemberton • Honest and dedicated, but ill-suited for the leadership demands of Vicksburg • Served under William Worth, an inflexible and irascible commander, in Mexico • Previous Civil War service had focused on fortifications and batteries to defend against naval attack • Virtually no experience in leading an army in the field • An example of the “Peter Principle”

48. The Peter Principle • The theory that employees within an organization will advance to their highest level of competence and then be promoted to and remain at a level at which they are incompetent.

49. Grant’s Move Inland • As Grant moved away from his new base at Grand Gulf, Pemberton expected him to stay close to the river to take advantage of his supply depots • Grant’s move inland caught Pemberton by surprise

50. Sherman and Grierson’s Diversions • Grant helped confuse Pemberton even more by having Sherman send a strong force back up the Yazoo to create a diversion around Hayne’s Bluff that convinced Pemberton the main attack was coming from that direction • Grant also sent Benjamin Grierson on a cavalry raid from Tennessee into Mississippi that led Pemberton to inefficiently divert units from his strategic reserve to chase after Grierson
