On the afternoon of July 3rd, 1863, roughly 12,000 Confederate soldiers formed up in the woods west of Seminary Ridge in southern Pennsylvania and prepared to walk nearly a mile across open farmland into the face of one of the most defensible positions the Army of the Potomac had ever occupied. What followed has been analyzed, mythologized, and debated for 160 years. It has been called the high water mark of the Confederacy, a suicidal blunder, the moment the war turned. All of those descriptions carry partial truth.
But the question that gets lost inside the drama of the flags and smoke and the terrible arithmetic of the dead is not what happened during those 45 minutes of open field assault. The failure of Pickett’s Charge was not decided on Cemetery Ridge. It was decided in the hours and days before, in errors of intelligence, arrogance, and misread terrain, in the mechanical failures of artillery fuses, and in the slow hemorrhage of an army already fighting for two days. By the time the first Confederate soldier broke from the tree line, the outcome had already been shaped by forces that no amount of courage could undo.
Robert E. Lee arrived at Gettysburg carrying a burden few commanders in military history have ever managed: the weight of his own legend. He had just come off Chancellorsville, where he had divided his army against a numerically superior opponent, outmaneuvered Joseph Hooker at every turn, and delivered what many observers considered the most brilliant tactical performance of the entire war. His men believed in him with a religious intensity that went beyond professional confidence.
They believed, on some level, that he could not be beaten. And there is evidence that Lee himself had begun to absorb some version of that belief. Not in a vain or careless way, but in the deeper and more insidious manner of a commander who has come to trust his army’s ability to execute beyond what any army can sustain indefinitely. He arrived in Pennsylvania with an elevated sense of what his men could do and a corresponding underestimation of what George Gordon Meade’s Army of the Potomac could do in a strong defensive position.
That imbalance shaped every decision Lee made from July 1st through the morning of July 3rd. On the first day, his forces had driven the Union First and Eleventh Corps through the town and up onto Cemetery Hill in a rout that suggested the kind of collapse Lee had seen at Second Manassas and Fredericksburg. His instinct was to press the advantage. Richard Ewell, commanding the Confederate Second Corps in Stonewall Jackson’s place, a command he had held for barely six weeks, failed to push that afternoon, and the Union Army consolidated on high ground overnight.
On the second day, Lee attempted to hammer both flanks simultaneously, a plan that depended on precise coordination across difficult terrain between corps commanders receiving their orders late and moving through country none of them knew well. James Longstreet’s assault on the Union left did not go in until mid-afternoon. John Bell Hood’s men fought savagely around Little Round Top and the Devil’s Den. A.
P. Hill’s Corps pushed against the Union center. Ewell struck Culp’s Hill and Cemetery Hill on the right. The attacks were fierce and in several places nearly successful, but nearly is a word that gets men killed and changes nothing.
By nightfall on July 2nd, the Army of the Potomac still held the ridge. That brings the story to the morning of July 3rd and to the most consequential conversation Robert E. Lee had during the entire battle. James Longstreet had been Lee’s most trusted lieutenant for two years.
He was not a flamboyant commander, not a man who gave speeches before dawn. He was methodical, stubborn, slow to move, but hard to stop. His corps had carried the weight of some of the Confederacy’s most punishing fighting, and from that experience he had developed a tactical philosophy fundamentally at odds with what Lee was about to propose. Longstreet believed in the tactical defensive.
He believed the Confederate Army’s best chance in Pennsylvania, perhaps its only viable chance, was to maneuver between Meade and Washington, force Meade to attack on Confederate-chosen ground, and use the same advantages of terrain and rifle firepower that had made Fredericksburg a massacre for the Union. He had said as much before the campaign began and again when they arrived at Gettysburg. On the morning of July 3rd, Lee told Longstreet he intended to assault the Union center on Cemetery Ridge with Pickett’s fresh division as the spearhead, reinforced by portions of A. P.
Hill’s Corps under Johnston Pettigrew and Isaac Trimble. Longstreet’s response was unambiguous. He told Lee that no 15,000 men who ever lived could cross that ground under that fire and take that position. He said it plainly.
He had spent a career watching what rifled muskets and prepared positions did to attacking infantry. Lee listened, acknowledged the objection, and ordered the assault anyway. He believed the Union center had been weakened by the previous day’s fighting on the flanks. He believed a concentrated artillery bombardment could suppress the Union guns and break the infantry’s resolve before the attack went in.
He believed his men were capable of what no army should have been asked to do. He was wrong on every count. The ground itself was the first indictment. The distance from Seminary Ridge to Cemetery Ridge across the center runs to somewhere between three-quarters of a mile and a full mile of open farmland.
In 1863, that ground was cultivated fields and low grasses, broken only by the Emmitsburg Road with its post and rail fences, a few scattered farm structures, and almost no natural cover of any meaningful kind. An attacking force would be visible and exposed for virtually the entire approach. Every Union soldier on that ridge with a rifle could see them. Every artillery piece could track them.
The geometry of the attack meant that as the Confederate column moved east toward the ridge, it would pass through a crossfire from Union guns on Little Round Top to the south and Cemetery Hill to the north, flanking fire the attacking men could do nothing about. They could not turn to face it, could not charge and suppress it. They could only absorb it and keep moving. There had been successful infantry assaults over open ground before 1863, but they almost universally shared a characteristic Pickett’s Charge conspicuously lacked.
The attacking force was able to close the distance quickly enough, and the defending force was using weapons inaccurate enough for the assault to succeed before firepower annihilated the formation. The smoothbore musket of the Napoleonic era had limited range and accuracy. A trained infantryman could reliably hit a man-sized target at perhaps 50 to 80 yards. Massed frontal assault was built around those limitations.
By 1863, that calculus had been overturned. The Springfield Model 1861 and the Enfield Pattern 1853, the two most common rifles at Gettysburg, were rifled weapons with a practical effective range of 300 to 400 yards, extending beyond 500 in skilled hands. These were not exceptional shots. These were ordinary infantry engagements.
A defender with a rifled musket could begin killing men at ranges where a smoothbore could not even guarantee a hit. An attacking force crossing open ground could expect damaging fire across most of the approach, not just in the final 100 yards. The Confederate high command understood this problem, at least abstractly. It was why the artillery preparation was so central to Lee’s plan.
If the Union guns could be suppressed, if the defenders on the ridge could be shaken and their ammunition exhausted, the infantry might cross the killing ground with something approaching manageable casualties. The entire assault depended on that bombardment doing what Lee needed it to do. The Confederate artillery on Seminary Ridge opened at approximately 1:00 in the afternoon. Somewhere between 150 and 170 guns began one of the most intense artillery preparations of the entire war.
The sound carried for 30 miles. It shook the ground beneath the men waiting in the woods. For an hour and 45 minutes, the Confederate guns pounded the Union position. From the Confederate side, the bombardment looked and sounded devastating.
The smoke was enormous, visibility poor, and it seemed inconceivable that anyone could survive on that ridge under that weight of iron. But there were critical problems. The Confederate guns had a tendency to overshoot. The exact reason has been debated: smoke obscuring accurate observation, the slight uphill angle of the ridge, the mechanics of gun carriages recoiling on soft ground and gradually elevating their barrels.
Whatever the combination, a significant portion of the fire was landing behind Cemetery Ridge rather than on it. It was killing horses and destroying ammunition wagons in the rear areas, disrupting the Union support echelon, but it was not suppressing the infantry and artillery on the forward face of the ridge, the exact men and guns Pickett’s division would have to walk into. The Union artillery commander, Brigadier General Henry Hunt, understood what was happening from the Union side. He also understood something the Confederate commanders did not fully appreciate.
His guns were running low on ammunition, and if he kept them firing through the full Confederate bombardment, they would be nearly empty when the infantry stepped off. Hunt made a decision that was tactically counterintuitive and exactly correct. He ordered the Union guns to slow and then cease their fire, conserving ammunition for the infantry assault he knew was coming. When the Confederate gunners saw the Union fire slacken and then stop, the conclusion drawn on Seminary Ridge was predictably wrong.
They believed they had suppressed the Union artillery. They believed the position had been softened. Colonel Edward Porter Alexander, commanding the Confederate artillery, sent a message to Pickett. The effect had been good, the time was right, and if the infantry was going to advance, it needed to go now before the Confederate guns ran out of ammunition themselves.
This is the moment that deserves to be held still and examined. The Confederate bombardment, despite its staggering volume, had largely missed its intended targets. The Union infantry was still intact on the ridge. Hunt’s guns had gone quiet, not because they were destroyed, but because they were conserving rounds for what was coming.
The signal for the Confederate infantry to advance, the silence of the Union artillery, was not evidence that the position had been prepared for assault. It was the opposite. Every condition Lee had counted on to make the charge possible had already failed before the first rank stepped into the open field.
The courage of the men who made that walk has been rightfully honored ever since, but the decision that sent them into it had already been condemned, not on Cemetery Ridge, but in the command tents and artillery lines of the morning.
