context_page_description: The siege of Vicksburg was the final major military action in the Vicksburg campaign of the American Civil War. In a series of maneuvers, Union Maj. Gen. Ulysses S. Grant and his Army of the Tennessee crossed the Mississippi River and drove the Confederate Army of Mississippi, led by Lt. Gen. John C. Pemberton, into the defensive lines surrounding the fortress city of Vicksburg, Mississippi.
  Vicksburg was the last major Confederate stronghold on the Mississippi River; therefore, capturing it completed the second part of the Northern strategy, the Anaconda Plan. When two major assaults against the Confederate fortifications, on May 19 and 22, were repulsed with heavy casualties, Grant decided to besiege the city beginning on May 25. After holding out for more than forty days, with their supplies nearly gone, the garrison surrendered on July 4. The successful ending of the Vicksburg campaign significantly degraded the ability of the Confederacy to maintain its war effort. This action, combined with the surrender of the down-river Port Hudson to Maj. Gen. Nathaniel P.
context_section_description: Grant wanted to overwhelm the Confederates before they could fully organize their defenses and ordered an assault against the Stockade Redan for May 19. Troops from Sherman's corps had a difficult time approaching the position under rifle and artillery fire from the 36th Mississippi Infantry, Brig. Gen. Louis Hébert's brigade. They had to negotiate a steep ravine protected by abatis and cross a 6-foot-deep (1.8 m), 8-foot-wide (2.4 m) ditch before attacking the 17-foot-high (5.2 m) walls of the redan. This first attempt was easily repulsed. Grant ordered an artillery bombardment to soften the defenses and at about 2 pm, Sherman's division under Maj. Gen. Francis P. Blair tried again, but only a small number of men were able to advance even as far as the ditch below the redan. The assault collapsed in an exchange of rifle fire and hand grenades lobbing back and forth.
  The failed Union assaults of May 19 damaged troop morale, deflating the confidence the soldiers had felt after their string of victories across Mississippi. They were also costly, with 157 killed, 777 wounded, and eight missing, versus Confederate casualties of eight killed and 62 wounded. The Confederates, assumed to be demoralized, had regained their fighting edge.
  Grant planned another assault for May 22, but this time with greater care; his troops would first reconnoiter thoroughly and soften up the defenses with artillery and naval gunfire. The lead units were supplied with ladders to ascend the fortification walls. Grant did not want a long siege, and this attack was to be by the entire army across a wide front.
  Despite their bloody repulse on May 19, Union troops were in high spirits, now well-fed with provisions they had foraged. On seeing Grant pass by, a soldier commented, "Hardtack". Soon all Union troops in the vicinity were yelling, "Hardtack! Hardtack!" The Union served hardtack, beans, and coffee the night of May 21. Everyone expected that Vicksburg would fall the next day.
  Union forces bombarded the city all night, from 220 artillery pieces and with naval gunfire from Rear Adm. David D. Porter's fleet in the river. While causing little property damage, they damaged Confederate civilian morale. On the morning of May 22, the defenders were bombarded again for four hours before the Union attacked once more along a 3-mile (5 km) front at 10 am.
  Sherman attacked once again down the Graveyard Road, with 150 volunteers (nicknamed the forlorn hope detachment) leading the way with ladders and planks, followed by the divisions of Blair and Brig. Gen. James M. Tuttle, arranged in a long column of regiments. They hoped to achieve a breakthrough by concentrating their mass on a narrow front. They were driven back in the face of heavy rifle fire. Blair's brigades under Cols. Giles A. Smith and T. Kilby Smith made it as far as a ridge 100 yards from Green's Redan, the southern edge of the Stockade Redan, from where they poured heavy fire into the Confederate position, but to no avail. Tuttle's division, waiting its turn to advance, did not have an opportunity to move forward. On Sherman's far right, the division of Brig. Gen. Frederick Steele spent the morning attempting to get into position through a ravine of the Mint Spring Bayou.
  McPherson's corps was assigned to attack the center along the Jackson Road. On their right flank, the brigade of Brig. Gen. Thomas E. G. Ransom advanced to within 100 yards of the Confederate line, but halted to avoid dangerous flanking fire from Green's Redan. On McPherson's left flank, the division of Maj. Gen. John A. Logan was assigned to assault the 3rd Louisiana Redan and the Great Redoubt. The brigade of Brig. Gen. John E. Smith made it as far as the slope of the redan, but huddled there, dodging grenades until dark, when they were recalled. Brig. Gen. John D. Stevenson's brigade advanced in two columns against the redoubt, but their attack also failed when they found their ladders were too short to scale the fortification. Brig. Gen. Isaac F. Quinby's division advanced a few hundred yards, but halted for hours while its
