The artillery fell silent at one o’clock in the afternoon, and for a moment the mile of open ground between Seminary Ridge and Cemetery Ridge seemed to hold its breath. Lieutenant General James Longstreet stood with his staff, watching the smoke drift off the guns. He had argued against this from the first moment Lee had proposed it. He had pleaded, reasoned, and warned.

He had told his commander that no 15,000 men ever arranged for battle could take that position. Lee had waved it off. Now the cannonade was over, and the order to advance was about to be given, and Longstreet knew he was about to watch thousands of men walk into a slaughter that he had seen coming for two days. He was a big man, broad-shouldered, with a stern face that rarely betrayed what he was thinking.

At forty-two, James Longstreet had spent two decades as a soldier. He had charged through enemy fire at Chapultepec in Mexico, fought through the Seven Days, hammered the Federals at Second Manassas, held the line at Antietam, and turned Marye’s Heights into a killing ground at Fredericksburg. Lee called him his old warhorse. He trusted Longstreet implicitly, consulted him on strategy, leaned on his judgment.

But on the morning of July 3, 1863, the two men stood on opposite sides of a divide that no amount of shared battlefields could bridge. Longstreet was born in 1821 in South Carolina and raised on a Georgia plantation. He graduated from West Point in 1842, scraping by academically but proving himself a natural leader. The Mexican-American War made him a brevet hero and left him with a limp that stayed with him for life.

When the war between the states broke out in 1861, he resigned his commission in the United States Army and joined the Confederacy, rising quickly through the ranks. He had built his reputation fighting beside Lee, but the two men thought about war differently. Longstreet believed in defensive tactics, in letting the enemy come to you and wearing him down on your own terms. Offensive strategy, but defensive tactics, he later wrote.

It was a philosophy that had served him well. At Gettysburg, it collided head-on with Lee’s aggressive instinct to attack. The road to Gettysburg began after the Confederate victory at Chancellorsville in May 1863. Lee, emboldened by that triumph despite the loss of Stonewall Jackson, proposed an invasion of the North.

The plan was bold: shift the war out of battered Virginia, gather supplies from Pennsylvania’s fertile farms, and perhaps force a peace by threatening Washington or Philadelphia. Longstreet had his doubts from the start. He had just returned from a detachment in Suffolk, Virginia, where he had been sent on a foraging operation that he considered a waste of his corps. He argued instead for reinforcing the Western Theater, sending troops to Braxton Bragg in Tennessee or relieving Vicksburg, which was under siege.

But Lee overruled him, insisting the main effort stay in the East. Longstreet agreed to the invasion, but with a caveat. He believed the campaign should be fought defensively, that they should force the enemy to attack them in a strong position. In his postwar memoirs, he claimed Lee had promised as much.

Lee later denied it, calling the claim absurd, but the disagreement pointed to the tension that would explode at Gettysburg. The Army of Northern Virginia marched north in June, crossing into Pennsylvania. Longstreet’s corps trailed behind, guarding the wagon trains. The Confederates were fighting blind: Jeb Stuart’s cavalry was off on a raid, and no one knew exactly where the Union Army was.

Longstreet hired a spy named Harrison, who brought word of Union movements, but the intelligence was incomplete. The campaign stumbled forward on guesswork. July 1 began as a skirmish. Confederate brigades under A.

P. Hill bumped into Union cavalry west of Gettysburg, and what should have been a minor clash ballooned into a full engagement. Union General John Reynolds rushed reinforcements forward, but he was killed early in the fighting. By afternoon, Richard Ewell’s corps arrived and pushed the Federals through the town of Gettysburg to the high ground to the south: Cemetery Hill and Culp’s Hill.

Lee reached the field that evening and ordered Ewell to take the hills if practicable. Ewell hesitated, and the moment passed. It was a hesitation that would haunt the Confederates for the rest of the battle. The Union Army, under George Meade, who had replaced Joe Hooker only days before, dug in along Cemetery Ridge, forming a fishhook-shaped line that ran from Culp’s Hill down to the Round Tops.

Longstreet’s corps was still marching, strung out along the roads. He arrived that night, and when he saw the Union position, he urged Lee to maneuver south around the Union left, to place the Confederate army between Meade and Washington. We could not call the enemy to a position better suited to our plans, he argued. All we have to do is file around his left and secure good ground.

Lee refused. If the enemy is there tomorrow, we must attack him. Longstreet pushed back. If he is there, it will be because he is anxious that we should attack him.

A good reason in my judgment for not doing so. It was the first crack in their unity, and it would only widen. By July 2, Longstreet’s divisions under McLaws and Hood arrived, exhausted from a grueling march. Lee planned a series of echelon attacks: Longstreet against the Union left, Ewell against the right at Culp’s Hill.

But the day was plagued by delays. Longstreet had to countermarch his troops to avoid detection, and the attack did not get underway until late afternoon. Again he suggested flanking around the Round Tops. Again Lee pointed to the map.

Attack up the Emmitsburg Road. Longstreet confided to Hood that morning: The general is a little nervous this morning. He wishes me to attack. I do not wish to do so without Pickett.

I never like to go into battle with one boot off. When the assault finally came, it was ferocious. Hood’s men charged into Devil’s Den and the Wheatfield, fighting hand to hand. McLaws hit the Peach Orchard, where Union General Dan Sickles had foolishly advanced his corps, creating a salient in the Union line.

The fighting was brutal, bayonets and clubbed muskets, rocks hurled in desperation. Hood was wounded early, his arm shattered. Longstreet rode among the troops, steadying the lines under fire. They pushed the Union back, but they could not take Little Round Top, where Colonel Joshua Chamberlain’s 20th Maine held the hill with a desperate bayonet charge.

On the Union right, Ewell’s attacks on Culp’s Hill and Cemetery Hill gained ground but faltered at dusk. Longstreet later called it the best three hours of fighting ever done by any troops on any battlefield. But it was not enough. Thousands were dead or wounded, and the Union line held.

That night, as surgeons worked by lantern light amid the groans of the dying, Longstreet met with Lee. He proposed withdrawing Hood and McLaws from their positions and swinging around the Union flank, forcing Meade to attack. Lee demurred, his eyes on the center of Cemetery Ridge. The enemy is there, he said.

I am going to strike him. Dawn on July 3 brought worse news. Ewell’s men had been driven off Culp’s Hill by a Union counterattack. Lee adjusted his plans.

Focus everything on the center. Longstreet would command the assault, using fresh troops: Pickett’s Virginia division, plus brigades from Hill’s corps under Pettigrew and Trimble. About 12,500 men in total. Wilcox and Lang would support the flanks.

Colonel E. P. Alexander’s artillery would soften the Union line with a massive bombardment before the infantry advanced. Longstreet was aghast.

He rode with Lee that morning, pleading his case. The terrain was a killer: an open field swept by Union guns, no cover for a mile. The Union position was too strong: entrenched infantry and massed artillery on high ground. There was no way to reach it without crossing a killing ground in full view of the enemy.

General, Longstreet said, I have been a soldier all my life. I have been with soldiers engaged in fights by couples, by squads, companies, regiments, divisions, and armies, and should know as well as anyone what soldiers can do. It is my opinion that no 15,000 men ever arranged for battle can take that position. He warned that pulling troops from the right would expose his flank.

Hood and McLaws were holding a mile along the right of his line against 20,000 men, he explained. Those men would follow a withdrawal, strike the flank of the assaulting column, and crush it. He suggested the attack would need at least 30,000 men to have any chance. Lee waved it off.

Overconfident from past victories, he believed his men were invincible. They will go through anywhere, he insisted. Longstreet’s depression deepened. Never was I so depressed as upon that day, he later confided to his staff.

He felt as if he were sending his men to slaughter. Weeks later, in a letter to his uncle, he wrote: General Lee chose the plan adopted. I consider it a part of my duty to express my views to the commanding general. If he approves and adopts them, it is well.

If he does not, it is my duty to adopt his views and to execute his orders as faithfully as if they were my own. Still, he tried to mitigate the damage. Around noon, he sent a note to Alexander. If the artillery fire does not have the effect to drive off the enemy or greatly demoralize him so as to make our effort pretty certain, I would prefer that you should not advise General Pickett to make the charge.

Alexander, young and eager, replied that the barrage would demoralize them enough. Longstreet organized the assault meticulously. Pickett’s men formed in two lines, Kemper and Garnett in front, Armistead supporting. Pettigrew and Trimble formed behind them.

The target was a copse of trees near a stone wall bend, a point on the Union line called the angle. Around one o’clock in the afternoon, the cannonade erupted. It was the largest bombardment of the war: 150 to 170 Confederate guns thundering for nearly two hours. Smoke blanketed the field, but the Union batteries replied fiercely.

Alexander’s ammunition began to run low. He urged Pickett forward. Longstreet rode forward to check the situation. When Pickett asked if he should advance, Longstreet nodded silently.

Words failed him, choked by emotion. At three o’clock, the charge began. Thirteen thousand gray-clad soldiers stepped out of the treeline and formed their ranks. Flags waved.

The bands played. They advanced steadily across the open fields toward Cemetery Ridge. Union artillery tore gaps in their lines, canister shot working like giant shotguns, shells exploding overhead. Men fell in heaps, but the survivors closed ranks and kept walking, yelling the rebel cry.

Halfway across, the fences slowed them. At the Emmitsburg Road, the crossfire intensified. Pettigrew’s left crumpled under enfilade fire from the Union flank. Pickett’s Virginians angled toward the right, focusing on the angle.

Lewis Armistead led the final rush, his hat on the tip of his sword, over the stone wall and into a hand-to-hand frenzy. For a moment, they breached the Union line. It was the high-water mark of the Confederacy. But Union reinforcements poured in, fresh regiments from Hancock’s Second Corps.

Bayonets clashed, muskets were clubbed down on skulls. Armistead fell, mortally wounded, his hand on a Union cannon. It was over in thirty minutes. The survivors staggered back across the field, leaving it carpeted with dead and wounded.

Pickett’s division lost two-thirds of its men. All three of his brigadiers were down. Total Confederate casualties that day exceeded 6,000. When Lee met the remnants of the assault, he said, All this has been my fault.

It is I that have lost this fight. Longstreet, watching from the ridge, felt vindicated, but heartbroken. The retreat began on July 4, amid rain and mud. Wagons loaded with wounded groaned southward.

Meade pursued cautiously, missing his chance to destroy Lee’s army. The combined casualties at Gettysburg were 51,000: 23,000 Union, 28,000 Confederate. It was the bloodiest battle of the war. Lee’s invasion was shattered.

Vicksburg fell the same day, splitting the Confederacy in two. In the aftermath, blame swirled. Lee took responsibility in his official report, but after the war the Lost Cause mythmakers, Jubal Early and Fitzhugh Lee among them, scapegoated Longstreet. They accused him of sulking, of delaying on July 2, of disobeying sunrise attack orders that never existed.

Longstreet’s real sins were political: he became a Republican, supported Reconstruction, and criticized Lee in his memoirs. He defended himself. I had offered my objections to Pickett’s battle and had been overruled, he wrote. Historians now side with him.

His cautions were sound. Lee’s hubris was costly. What if they had listened? A flank maneuver might have drawn Meade out, prolonged the war, or forced negotiations.

Instead, Gettysburg marked the turning point. Union morale soared. Foreign recognition for the South faded. Longstreet lived until 1904, serving as a diplomat and a railroad commissioner, but he was always shadowed by Gettysburg.

His legacy is that of a brilliant tactician who saw the price of folly before it was paid, and was ignored.
