A Turning Point?
It is often said that the Battle of Gettysburg (July 1-3, 1863) was the turning point of the American Civil War. I agree; it was a turning point! But only from the perspective that it 'turned' General Robert E. Lee and the Army of Northern Virginia around, sending them back across the Potomac. But to suggest that it was the single 'strategic' event that spun the war favoring the North is a little ambitious! It is true that the Army of Northern Virginia never really recovered from the casualty losses it sustained over the three days in southern Pennsylvania, and those immense losses managed to tarnish Lee's reputation in some Southern circles. It is also true from a Northern perspective; Gettysburg quashed the fear of Lee's invincibility. However, Union Major General George G. Meade failed to pursue the retreating army, missing a critical opportunity to trap Lee and force a Confederate surrender. After the withdrawal from Pennsylvania, Lee's Army of Northern Virginia continued to fight for another 21 months; until the surrender at Appomattox Courthouse on April 9, 1865. That was a further 647 days of bloodletting at the Wilderness, Spotsylvania Court House, Cold Harbor, Petersburg, Fort Steadman, Five Forks, and the Battle of Appomattox Court House.
After a year of defensive victories in Virginia, Robert E. Lee's objective was to win a battle north of the Mason-Dixon line in the hopes of forcing a negotiated end to the fighting. After a great victory at Chancellorsville, Lee marched his Army of Northern Virginia into Pennsylvania in late June 1863. On July 1, advancing Confederates clashed with the Union Army of the Potomac, commanded by General George G. Meade, at the little crossroads town of Gettysburg. The next day saw even heavier fighting as the Confederates attacked the Federals on their left and right flanks. On July 3, Lee ordered an attack by fewer than 15,000 troops on the enemy's center at Cemetery Ridge. The assault, known as 'Pickett's Charge,' managed to pierce the Union lines but eventually failed at the cost of thousands of casualties. Forced to withdraw, Lee maneuvered his battered army toward Virginia on July 4. The Union victory stopped Lee's ambitious second quest to invade the North and bring the Civil War to a swift end. The loss destroyed the hopes of the Confederate States of ever becoming an independent nation.
What linked Gettysburg to a turning point in the war was the fall of Vicksburg on July 4, 1863. The loss of Vicksburg (often referred to as the Gibraltar of the Confederacy) sent reverberations through the walls of the Confederate Congress that sent the South into a losing spiral from which they would never recover. Vicksburg was their key to momentum, and the defeat here marked the turning point after which the South lost their ability to continue the war.
The Mississippi River provided an essential lifeline for the South during the war. Not as an obvious open watercourse that one would imagine. The loss of New Orleans and Baton Rouge to the south, and Memphis to the north, which included Fort Henry and Donaldson's capture, restricted any Confederate movement up and down the river. However, it did provide a significant geographical barrier that protected Vicksburg and its vital rail link between the armies to the east of the Mississippi River and the trans-Mississippi region, consisting of Missouri, Arkansas, Texas, the Indian Territories (now Oklahoma) and Louisiana, to the west. Both Abraham Lincoln and Jefferson Davis recognized the significance of Vicksburg; they also recognized that capturing Vicksburg would sever the Trans-Mississippi Confederacy. Such a loss would open the river along its entire length to traffic from the north; thus, preventing Texas beef, Louisiana sugar, salt, and molasses from passing east through Vicksburg and helping to sustain the war effort. According to the Civil War Trust (2014), in an article entitled: 'Unlocking the Door to Union Victory,' President Lincoln is quoted as saying:
"See what a lot of land these fellows hold, of which Vicksburg is the key! The war can never be brought to a close until that key is in our pocket. We can take all the northern ports of the Confederacy, and they can defy us from Vicksburg."
~ Abraham Lincoln (1862).
The two reasons that are most widely accepted as determining the outcome of the Battle of Gettysburg are the Union's tactical advantage (due to the occupation of the high ground) and the absence of J.E.B. Stuart's Confederate cavalry on the first day of fighting. Though the cautious Meade would be later criticized for not pursuing the enemy after Gettysburg, the battle was a crushing defeat for the Confederacy. Union casualties numbered 23,000, while the Confederates had lost some 28,000 men—more than a third of Lee's army. With more than 50,000 estimated casualties, the three-day engagement was the bloodiest single battle of the American Civil War.
