The Fight at Cemetery Ridge

The charge was planned for three Confederate divisions, commanded by Maj. Gen. George Pickett, Brig. Gen. J. Johnston Pettigrew, and Maj. Gen. Isaac R. Trimble, consisting of troops from Lt. Gen. James Longstreet's First Corps and Lt. Gen. A.P. Hill's Third Corps. Pettigrew commanded brigades from Maj. Gen. Henry Heth's old division, under Col. Birkett D. Fry (Archer's Brigade), Col. James K. Marshall (Pettigrew's Brigade), Brig. Gen. Joseph R. Davis, and Col. John M. Brockenbrough. Trimble, commanding Maj. Gen. Dorsey Pender's division, had the brigades of Brig. Gens. Alfred M. Scales and James H. Lane. Two brigades from Maj. Gen. Richard H. Anderson's division (Hill's Corps) were to support the attack on the right flank: Brig. Gen. Cadmus M. Wilcox and Col. David Lang (Perry's brigade).

The target of the Confederate assault was the center of the Union Army of the Potomac's II Corps under Maj. Gen. Winfield S. Hancock. Directly in the center was the division of Maj. Gen. John Gibbon with the brigades of Brig. Gen. William Harrow, Col. Norman J. Hall, and Brig. Gen. Alexander S. Webb. To the north of this position were brigades from the division of Brig. Gen. Alexander Hays, and to the south was Maj. Gen. Abner Doubleday's division of the I Corps, including the 2nd Vermont Brigade of Brig. Gen. George J. Stannard. General Meade's headquarters were just behind the II Corps line, in the small house owned by the widow Lydia Leister.

From the beginning of the planning, things went awry for the Confederates. While Pickett's division had not been used yet at Gettysburg, A.P. Hill's health became an issue and he did not participate in selecting which troops of his were to be used for the charge. Some of Hill's corps had fought lightly on July 1 and not at all on July 2. However, troops that had done heavy fighting on July 1 ended up making the charge.

Although the assault is known to popular history as Pickett's Charge, overall command was given to James Longstreet, and Pickett was one of his divisional commanders. Lee did tell Longstreet that Pickett's fresh division should lead the assault, so the name is appropriate, although some recent historians have used the name Pickett-Pettigrew-Trimble Assault (or, less frequently, Longstreet's Assault) to more fairly distribute the credit (or blame). With Hill sidelined, Pettigrew's and Trimble's divisions were delegated to Longstreet's authority as well. Thus, General Pickett's name has been lent to a charge in which he commanded about one third of the men and was under the supervision of his corps commander throughout. Pickett's men were almost exclusively from Virginia, with the other divisions consisting of troops from North Carolina, Mississippi, Alabama, and Tennessee. The supporting troops under Wilcox and Lang were from Alabama and Florida.

In conjunction with the infantry assault, Lee planned a cavalry action in the Union rear. J.E.B. Stuart led his cavalry division to the east, prepared to exploit Lee's hoped-for breakthrough by attacking the Union rear and disrupting its line of communications (and retreat) along the Baltimore Pike.

Despite Lee's hope for an early start, it took all morning to arrange the infantry assault force. Meanwhile, on the far right end of the Union line, a seven-hour battle raged for the control of Culp's Hill. Lee's intent was to synchronize his offensives across the battlefield, keeping Meade from concentrating his numerically superior force, but the assaults were poorly coordinated and Edward "Allegheny" Johnson's attacks against Culp's Hill petered out just as Longstreet's cannonade began.

Artillery barrage

The infantry charge was preceded by what General Lee hoped would be a powerful and well-concentrated cannonade of the Union center, destroying the Union artillery batteries that could defeat the assault and demoralizing the Union infantry. But a combination of inept artillery leadership and defective equipment doomed the cannonade from the beginning. Longstreet's corps artillery chief, Colonel Edward Porter Alexander, was in effective command of the field; Lee's artillery chief, Maj. Gen. William N. Pendleton, played little role other than to obstruct the effective placement of artillery from the other two corps. Despite Alexander's efforts, then, there was insufficient concentration of Confederate fire on the objective.

The July 3 bombardment was likely the largest of the war, with hundreds of cannons from both sides firing along the lines for almost two hours, starting around 1 p.m. Confederate guns numbered between 150 and 170 and fired from a line over two miles (3 km) long, starting in the south at the Peach Orchard and running roughly parallel to the Emmitsburg Road. Confederate Brig. Gen. Evander M. Law wrote, "The cannonade in the center ... presented one of the most magnificent battle-scenes witnessed during the war. Looking up the valley towards Gettysburg, the hills on either side were capped with crowns of flame and smoke, as 300 guns, about equally divided between the two ridges, vomited their iron hail upon each other."

Despite its ferocity, the fire was mostly ineffectual. Confederate shells often overshot the infantry front lines, and the smoke covering the battlefield concealed that fact from them. Union artillery chief Brig. Gen. Henry J. Hunt had only about 80 guns available to conduct counter-battery fire; the geographic features of the Union line had limited areas for effective gun emplacement. He also ordered that firing cease to conserve ammunition, and Alexander interpreted this to mean that many of the batteries had been destroyed. (Hunt had to resist the strong arguments of General Hancock, who demanded Union fire to lift the spirits of the infantrymen pinned down under Alexander's bombardment. Even Meade was affected by the artillery—the Leister house was a victim of frequent overshots, and he had to evacuate with his staff to Powers Hill.)

The day was hot, 87 °F (31 °C) by one account and humid, and the Confederates suffered under the hot sun awaiting the order to advance. But they suffered from the Union counter-battery fire as well. When Union cannoneers overshot their targets, they often hit the massed infantry waiting in the woods of Seminary Ridge or in the shallow depressions just behind Alexander's guns, causing significant casualties before the charge began.

From the beginning, Longstreet opposed the charge, preferring his own plan for a strategic movement around the Union left flank. He told Lee that he did not think there were "15,000 men on earth capable of taking that [the Union] position." Longstreet looked for ways to avoid ordering the charge by attempting to pass responsibility to young Col. Alexander, but he eventually did pass the order himself non-verbally; when Alexander notified Pickett that he was running dangerously short of ammunition, Longstreet nodded reluctantly to Pickett's request to step off. For Pickett, there was virtually no Confederate artillery with ammunition available to support his assault directly.

Infantry assault

The entire force that charged against the Union positions consisted of about 12,500 men, marching deliberately in line with Pettigrew and Trimble on the left, and Pickett to the right. The nine brigades of men stretched over a mile-long (1,600 m) front. The Confederates encountered heavy artillery fire while advancing across open fields nearly a mile to reach the Union line. The ground between Seminary Ridge and Cemetery Ridge is slightly undulating, and the advancing troops periodically disappeared from the view of the Union cannoneers. As the three Confederate divisions advanced, awaiting Union soldiers began shouting "Fredericksburg! Fredericksburg! Fredericksburg!" in reference to the disastrous Union advance on the Confederate line during the 1862 Battle of Fredericksburg. Murderous fire from Lt. Col. Freeman McGilvery's concealed artillery positions north of Little Round Top raked the Confederate right flank; fire from Cemetery Hill hit the left. Shell and solid shot in the beginning turned to canister and musket fire as the Confederates came within 400 yards of the Union line. The mile-long front shrank to less than half a mile (800 m) as the men filled in gaps that appeared throughout the line and they followed their natural tendency to move away from the flanking fire.

On the left flank of the attack, Brockenbrough's brigade virtually evaporated, decimated by artillery fire from Cemetery Hill. Davis's brigade, on the left flank of the charge, was subjected to the direct attention of the artillery and to a surprise musket fusillade from the 8th Ohio Infantry regiment, which had moved out from its position on the Emmitsburg Road to envelop Davis's left.

Pickett's Virginians had been subjected to the least fire in the beginning of the charge and wheeled to their left toward a minor salient in the Union center. This position of the lines was marked by a low stone wall taking a short right-angle turn known afterwards as "The Angle." They marched in two lines, led by the brigades of James L. Kemper on the right and Richard B. Garnett on the left; Lewis A. Armistead's brigade followed closely behind. As the division wheeled to the left, its right flank was exposed to the front of Doubleday's Union division on Cemetery Ridge. Stannard's Vermont Brigade marched forward, faced north, and delivered withering fire into the rear of Kemper's brigade.

The Confederates partially breached the Union's first line of defense but were forced back soon after as Union troops gathered on their right flank and stabilized the center of the line. The charge lasted less than an hour. The supporting attack by Wilcox and Lang on Pickett's right was never a factor; they did not approach the Union line until after Pickett was defeated, and their advance was quickly broken up by McGilvery's guns and by the Vermont Brigade.
