Meade’s troops had occupied a line along Cemetery Hill, Culp’s Hill, and Cemetery Ridge by dawn. Meade’s position would be undermined if the Confederates succeeded on the Federal right, as their line of communications along the Baltimore Pike would be threatened. Although Lee wanted to exploit this strategic weakness, Ewell argued that Longstreet should concentrate his attack on the opposite flank.
Lee, on the other hand, argued that Meade should attack. Due to the opposition of his corps commanders, Lee did not issue his orders until 11:00 AM. Longstreet was to encircle the Federal south flank and attack along the Emmitsburg Pike, where Lee mistakenly believed Meade’s line lay. Hills and Ewell would make secondary attacks. Longstreet’s artillery started firing at 3:00 PM, so Meade rushed to the south flank that had been overlooked and found that Sickles had not positioned his III Corps along Cemetery Ridge as directed,
but had moved forward to higher ground. The attack weakened the south flank and created a dangerous salient, but it was too late to pull him back. Longstreet’s corps attacked the Union left at 4:00 PM with Gen. John Bell Hood’s division.
July 3rd and Pickett’s Charge.
The third day, Lee attacked again despite Longstreet’s objections. Meanwhile, Meade was less confident, and it was only after a formal council of war that he decided to continue fighting. With Ewell making a secondary attack on Culp’s Hill, Lee planned to attack the Federal center with 10 brigades, three of which belonged to Pickett’s division. While Pickett’s Charge has been immortalized as the most famous attack of the Civil War, this general’s only responsibility was to organize the divisions of Brig.
Gen. James Johnston Pettigrew (who had assumed command of Heth’s division after Heth was wounded on July 1) and Gen. Isaac Trimble (who had assumed control of Pender’s division after Pender was mortally wounded on July 2) as they approached their attack positions on his left. The operation was led by Longstreet, not Pickett. Approximately 1:00 PM, the Confederate artillery began a tremendous bombardment, which was immediately countered by Federal artillery. At 3:00 PM, the infantry started across the 1,400 yards (1,280 metres) of open fields toward Cemetery Ridge. The Federals watched in awe as about 15,000 Confederate troops advanced toward them. After having ceased fire an hour earlier to save ammunition, the Federal artillery returned to action with devastating effect at a range of about 700 yards (640 metres).
Even though most of the Confederate artillery preparations went over their heads, the roughly 10,000 Federal infantry against whom the attack was directed waited coolly behind stone walls and held their fire until the Confederates were within effective range. After breaking through and entering Cemetery Ridge, the spearhead could not further advance. Having been severely weakened by artillery during their approach, their formations hopelessly tangled, lacking reinforcement, and under severe attack from three sides, they left behind the bodies of their dead and wounded as they marked “the high tide of the Confederacy.”
19 battle flags and hundreds of prisoners were left behind as the Confederates retreated, demoralized but not panicking. Several Union brigades advanced to hasten the retreat, but they were too roughly handled by the Army of the Potomac to mount a counterattack. gettysburg trading post
