Gettysburg’s Oldest General: How George Sears Greene’s Engineering Saved Culp’s Hill

[00:00:03]May 1863, the Virginia Wilderness. A Confederate army of 60,000 men executes one of the most audacious flank attacks in military history. Thomas Jonathan Stonewall Jackson, Lee's most trusted lieutenant, has marched his cores 12 miles through dense woodland, emerging on the unprotected right flank of the Union Army of the PTOIC. The attack that follows shatters the Union line. Joseph Hooker's army retreats in disorder.

[00:00:35]Chancellor'sville is a stunning Confederate victory. Two months later, July 1863, Pennsylvania farmland. Another flank, another desperate moment. But this time, the roles are reversed. It is the Union flank that is threatened. And the man who holds it is not a young, daring cavalryman. He is a 62-year-old engineer who has spent more of his life building bridges and aqueducts than commanding soldiers in battle. His name is George Sears Green.

[00:01:10]What he accomplishes on a densely wooded hill outside Gettysburg may be one of the most consequential and least celebrated defensive actions of the entire Civil War.

[00:01:21]At first glance, the comparison seems improbable. Stonewall Jackson at Chancellor'sville, the aggressive, tactically brilliant offensive maneuver that flanked an entire Union army.

[00:01:33]George Green at Gettysburg, a static, desperate defense against overwhelming odds. Different battles, different circumstances, different commanders.

[00:01:44]Yet, the tactical parallels are striking. Both men understood that a single vulnerable flank could determine the outcome of an entire battle. Both recognized that terrain was not merely a backdrop, but a weapon to be used. Both relied on rapid tactical judgment rather than overwhelming numbers. Jackson by moving his men with astonishing speed through difficult country. Green by understanding that prepared defensive positions could multiply effectiveness.

[00:02:15]Both men faced situations where the fate of their army hung on their decisions.

[00:02:20]Both acted with clarity of purpose that would define the battle. But the similarities end there. Jackson's flank march was offensive, a bold stroke to strike where least expected. Green's stand was defensive, a desperate attempt to hold ground that if lost would expose the entire Union Army.

[00:02:42]Jackson operated with a cores of nearly 30,000 men. Green commanded a single brigade of 1,400 New Yorkers. Jackson's attack achieved complete surprise and rolled up a Union Corps. Green's defense was a holding action against a Confederate division that outnumbered him more than 3 to one. The comparison is not meant to suggest the actions were identical. Understanding what they shared and how they differed illuminates something essential about Civil War combat. Both Jackson and Green demonstrated that it is not the size of the force that matters most. It is how that force is used. To understand what Green accomplished on Culps Hill, we must first understand how the Union Army came to be there. In the spring of 1863, the Confederacy found itself in a precarious position. The Army of Northern Virginia had won stunning victories at Fredericksburg and Chancellorsville. But these triumphs came at a terrible cost. Lee had lost Stonewall Jackson, his most capable subordinate, to friendly fire. His army was exhausted, undersupplied, and in desperate need of replenishment. Lee made a fateful decision. He would take the war north. An invasion of Pennsylvania would allow his army to live off rich farmland, relieve pressure on Virginia, threaten Washington, and potentially force the Union to recall troops from the Western Theater.

[00:04:12]Most ambitiously, a decisive victory on northern soil might bring foreign recognition to the Confederacy.

[00:04:19]Lee reorganized his army into three cores under Long Street, Ule, and Hill.

[00:04:25]In early June, they moved northward. The Union response was slow and uncertain.

[00:04:31]Major General Joseph Hooker, still smarting from Chancellor'sville, pursued cautiously.

[00:04:37]Lincoln grew frustrated with Hooker's inability to force a decisive engagement. On June 28th, Lincoln replaced Hooker with Major General George Gordon Meade. Me moved his army northward, seeking to place himself between Lee and Washington. Neither commander had anticipated fighting at Gettysburg. The battle began almost by accident on July 1st. Confederate forces advancing from the west and north encountered Union cavalry under John Buford, who had occupied the high ground outside Gettysburg. Both sides fed reinforcements into the fight. By day end, the Confederates had driven the Union troops through the town, but not before the Federals had seized the high ground to the south. The Union Army, battered and disorganized, retreated to a series of hills, Cemetery Hill, Cemetery Ridge, and anchoring the far right flank, a densely wooded elevation called Culps Hill. The line formed the shape of a fish hook. Culps Hill was at the barbed point. This was not a position the Union Army had chosen in advance. It had fallen back to it in desperation, but it was a strong one.

[00:05:48]The hills provided elevation, visibility, and defensive cover. Kulps Hill with its steep boulder strewn slopes and dense woods was especially formidable. It anchored the entire Union right flank and protected the army's vital supply line, the Baltimore Pike, which ran behind the hill. The irony was not lost on the soldiers who occupied it. Henry Culp, the farmer who owned the hill, had a nephew named Wesley Culp, who now served in the Confederate Army.

[00:06:19]Wesley had played on these slopes as a boy. Now he would return as a soldier.

[00:06:25]Culp's Hill rises approximately 140 to 200 ft above the surrounding landscape.

[00:06:32]Its slopes are covered with trees and large boulders, natural obstacles that would slow any attacking force. To the east flows Rock Creek, a substantial water course that would have to be crossed. To the west, the hill overlooks the Baltimore Pike and the rear areas of the Union Army. The hill's strategic importance was immediately apparent. It was not merely a defensive position. It was the defensive position. The entire Union line curved around it like a fish hook. If the Confederates could seize it, they would be in the rear of the Union Army. They could cut the Baltimore pike, severing the army's supply line and line of retreat. They could roll up the Union line. Major General Henry Sloum, commander of the Union 12th Corps, was given responsibility for holding Kulps Hill. His cores had seen hard fighting at Chancellor'sville, where it had suffered heavy casualties.

[00:07:28]Now it would be called upon to defend one of the most critical positions on the battlefield. But Sloukum's core was about to be stripped of most of its strength. The man left to hold the line was a 62-year-old engineer whose best years, by any conventional measure, were behind him. George Sears Green was born in Apenog, Rhode Island on May 6th, 1801.

[00:07:53]He came from a distinguished military family. His cousin was Nathaniel Green, one of George Washington's most trusted generals. But George Green's path to glory was anything but straightforward.

[00:08:06]Green's father, Caleb, lost much of his shipping fortune as a result of the Embargo Act of 1807.

[00:08:13]The family could no longer afford to send George to Brown University, his preferred institution.

[00:08:20]Instead, at age 18, Green entered the United States Military Academy at West Point. He excelled.

[00:08:28]In 1823, Green graduated second in his class of 35 cadetses. Such an achievement would normally have led to a commission in the Elite Corps of Engineers, the branch that drew the academyy's top graduates. But Green chose instead to join the artillery, accepting a commission as a second lieutenant in the third US artillery regiment. His brilliance was recognized immediately. He was appointed acting assistant professor of mathematics during his final year at West Point.

[00:09:01]After graduation, he remained at the academy for three years as a professor of mathematics and one year as an assistant professor of engineering.

[00:09:11]Green served in the army for 13 years, but his career was not especially distinguished. He was stationed in various garrisons, performed routine duties, and watched as younger officers advanced past him.

[00:09:25]In 1836, with the nation at peace, Green resigned his commission. He might have faded into obscurity, remembered only as a middling artillery officer from an old Rhode Island family. Instead, Green embarked on a second career, one that would prove unexpectedly relevant to his later military service. For the next 25 years, Green worked as a civil engineer, and he was extraordinarily successful.

[00:09:53]He designed and built railroads across the northeastern United States. He was chief engineer of the Croin Aqueduct Department, overseeing the construction of the system that brought fresh water to New York City. He designed and constructed the Great Reservoir in Central Park. He worked on water and sewer systems in several major American cities. In 1875, he was elected president of the American Society of Civil Engineers.

[00:10:21]When the Civil War broke out in 1861, Green was 60 years old, well past the age at which most men would consider returning to military service. But Green had not lost his sense of duty. In January 1862, he was appointed Colonel of the 60th New York Volunteer Infantry.

[00:10:42]The regiment had been dissatisfied with its previous colonel. The company commanders had petitioned for his removal. Green with his West Point training and decades of leadership experience was an obvious replacement.

[00:10:56]His age made him an anomaly. At 61, he was one of the oldest field commanders in the Union Army. His men called him old man or pap green, nicknames that were affectionate but also pointed to his advanced years. Yet Green proved to be an effective commander. His engineering background gave him a natural understanding of terrain and defensive positions. His West Point training gave him a disciplined approach to tactics and logistics. and his age, far from being a liability, gave him a perspective that younger, more impetuous officers sometimes lacked. One soldier who served under Green described him as an excellent officer with a kind heart beneath a rough exterior. The men learned to love and respect him as much as they initially feared him. He knew how to drill, how to command, and in the hour of peril, how to care for his command. Green's first significant combat experience came at Antidum in September 1862, where he directed an assault that penetrated Stonewall Jackson's defensive line near the Dunker Church. He fought at Chancellor'sville in May 1863, where his brigade saw its first major action as a unit. Then in the summer of 1863, his brigade was ordered to march north toward Pennsylvania toward Gettysburg toward the fight that would define his legacy. He was promoted to brigadier general on April 28th, 1862.

[00:12:33]His brigade consisted of five New York regiments, the 60th, 78th, 102nd, 137th, and 149th. They were part of the second division of the 12th corps commanded by Major General John W. Giri.

[00:12:50]By the time Green reached Gettysburg on the evening of July 1st, 1863, he was 62 years old, the oldest Union general on the field. He had spent more of his life building bridges and aqueducts than commanding soldiers. But his engineering experience was about to become the Union Army's most valuable asset.

[00:13:13]To understand why Culps Hill mattered and why Green's defense of it was so critical, we must understand the geography of the battlefield. The Union Army's position on July 1st to 3rd, formed a fish hook. The curve ran along Cemetery Ridge, a low open elevation stretching south from Gettysburg. The barb was Culps Hill. Cemetery Hill connected the two positions. This was not a line the Union Army had chosen. It was a line it had retreated to, but it was strong. The interior lines allowed me to shift troops quickly from one threatened sector to another. The Confederates, by contrast, occupied exterior lines, a longer perimeter that made it harder for Lee to coordinate attacks on different parts of the Union position.

[00:14:03]The Confederate army occupied a parallel fish hook along Seminary Ridge. The two armies faced each other across a mile of open fields with the town between them.

[00:14:14]Culps Hill was the key to the entire Union position. If the Confederates could seize it, they would be in the rear of the Union Army. They could cut the Baltimore Pike, the army's main supply line and line of retreat. They could roll up the Union line from flank to flank, potentially destroying the army of the PTOAC peace meal. On the morning of July 2nd, elements of the 12th Corps arrived to reinforce Kulps Hill. Among them was Green's brigade, approximately 1,400 men. Green surveyed the position with an engineer's eye. He saw a densely wooded slope with excellent fields of fire. He saw natural obstacles, boulders, ravines, thick undergrowth that would slow an attacking force. He saw that the position could be made even stronger with field fortifications.

[00:15:07]He immediately ordered his men to begin constructing breast works. His soldiers, most of whom had been farmers and laborers before the war, felled trees on the densely wooded slopes and stacked them into barricades. They used cordwood they found conveniently piled nearby.

[00:15:25]They gathered loose stones and piled them on top of the logs. By the time they were finished, the breast works were as high as 5 ft.

[00:15:35]Captain Jesse H. Jones of the 60th New York recalled that the men fell to work constructing log breast works with unaccustomed hardiness, instinctively feeling that a life and death struggle was impending.

[00:15:49]Green's decision to build breast works was controversial. Many officers on both sides opposed field fortifications.

[00:15:58]Confederate General John Bell Hood believed they would imperil the spirit of self-reliance that made Confederate soldiers effective. Union artillery man Charles Wright believed their use did not speak well for the morale of the men. Even Green's own division commander, General John Giri, was opposed. Giri believed that breast works unfitted men for fighting without them.

[00:16:21]But he left the decision to his brigade commanders.

[00:16:26]Green understood that his small force would need every advantage. He decided that the saving of lives was more important than such theories and that his men would build them if they had time. Thanks to Confederate inactivity, Green had time.

[00:16:43]The Confederates had frittered away most of the day, failing to coordinate their attacks. While they waited, Green's men worked. By late morning, the breast works were essentially complete, and the Federals had all day to improve their position. It was a decision that would save the Union Army. The second day, July 2nd, would prove one of the most consequential days of the entire war.

[00:17:08]Robert E. Lee's plan was ambitious. He intended to attack both ends of the Union line simultaneously.

[00:17:15]Long Street against the left, Ule against the right. The coordinated assault would stretch the Union Army to its breaking point, but the plan fell apart almost immediately. Long Street was slow to move, and his attacks did not begin until late afternoon. Ule waited for Long Street's attack to begin before launching his own diversion. The result was a series of peacemeal assaults rather than the coordinated hammer blow Lee had envisioned. The Union left was the first to be struck.

[00:17:48]Long Street's core slammed into the Third Corps, commanded by the impetuous Daniel Sickls, who had advanced his troops to an exposed position. The fighting was ferocious. As the crisis on the Union left deepened, me made a fateful decision. He ordered reinforcements from the right flank to be rushed to the left. The 12th Corps, the troops holding Culps Hill, would be the primary source. Major General Henry Sloum received orders to send most of his division to the left. General Alfus S. Williams began moving his troops out of their positions on Culps Hill. But one brigade was left behind. Green's brigade, the 1,400 New Yorkers of the Third Brigade was ordered to remain on Kulps Hill. Green was to hold the position with whatever forces he had.

[00:18:36]What Green had was not much. Most of the 12th Corps had been stripped away. His thin line was stretched to cover the entire front. He extended it as far as it would go. Me was confident that the thinly defended Kulps Hill would not be attacked. It was already past 6 in the evening. The day was waning. The Confederates me believed would not attack in the dark. He was mistaken. On the Confederate side, General Richard Ule had finally decided to act. He ordered three brigades of Major General Edward Alagany Johnson's division to assault Culps Hill. Johnson's division consisted of approximately 4,700 men.

[00:19:18]They were opposed by Green's 1,400 New Yorkers. The contrast could not have been starker. On one side, nearly 5,000 Confederate veterans eager to strike a blow that could win the battle. On the other, 1,400 New Yorkers, most of them farmers and laborers just months before, huddled behind hastily constructed breast works.

[00:19:41]Green's men were outnumbered more than 3 to one. They were defending the most critical position on the battlefield, the anchor of the Union right flank, the protector of the Baltimore Pike, the key to the entire Union position. They were about to face one of the most desperate assaults of the entire war. Before we follow the assault, we need to understand what Green had built. The breast works on Culps Hill were not simple log piles. They were carefully engineered defensive positions designed to maximize the effectiveness of a small force.

[00:20:14]Green's men constructed them using logs, cordwood, stones, and earth. They felled trees and stacked them into barricades.

[00:20:22]They added layer upon layer of wood and stone. And by the time they finished, the breast works were as high as 5 ft.

[00:20:30]The position also included a crucial feature, a traverse or extension leading from a sharp angle in the original works. This traverse allowed Green to extend his line and prevent the Confederates from outflanking him. Green positioned his regiments carefully. The 60th New York was placed on the upper crest. The 102nd and 149th New York were posted in the saddle.

[00:20:56]The 137th New York held the lower crest.

[00:21:00]Each regiment was positioned to maximize its fields of fire with overlapping fields that would make it difficult for attackers to find cover. The breast works also provided protection against artillery fire.

[00:21:13]Confederate batteries on Benner's Hill and Seminary Ridge opened fire on the Union positions. Green, whose original commission had been in the artillery, oversaw a federal canonade that silenced the rebel guns. The infantry behind the breast works were largely protected from the artillery fire that rained down around them. Green's engineering background had given him an understanding of defensive works that many of his contemporaries lacked. He knew that well- constructed breast works could multiply the effectiveness of a small force many times over. He knew that prepared positions could compensate for numerical inferiority.

[00:21:52]He knew that the Confederates attacking uphill through dense woods would be at a severe disadvantage. What he may not have known was just how desperate the fight would become. As twilight settled over the battlefield on July 2nd, Johnson's division began its advance.

[00:22:09]The Confederates forted Rock Creek and moved up the steep boulder strewn slopes of Culps Hill. The woods were dense. The light was fading. It was exactly the kind of attack that Green's breast works were designed to defeat. Johnson's three brigades struck Green's thin line. Two brigades hit the main hill. The third, Brigadier General George Marilyn Stewart's brigade, attempted to outflank the federal right. The Confederates ran headlong into Green's formidable breast works. The New Yorkers poured a devastating fire into the attacking ranks. The Confederates attacking uphill through dense woods had only the shelter afforded by trees and rocks. The Union troops fought from the cover of breast works. The effect was devastating.

[00:22:56]One soldier described the scene. The whole hillside seemed enveloped in a blaze. The Confederate charges were beaten off with relative ease by the 60th New York, which suffered very few casualties. Confederate casualties were high. General Jones was wounded and left the field. But the Confederates were not finished. Stuart's brigade managed to outflank the Federal right flank. The Union troops fell back to a hastily built extension of their works.

[00:23:25]Increasing darkness led to great confusion on both sides. Green's line was stretched to the breaking point. His men were exhausted, running low on ammunition. The Confederates had successfully occupied a portion of the 12th core trenches on lower Culps Hill.

[00:23:41]Trenches built by brigades that had earlier departed to reinforce the Union left, but Upper Culps Hill remained firmly in federal hands. Green's men held. Desperate for reinforcements, the Union command rushed whatever troops could be spared to Culps Hill. These included regiments from the first corps that had been badly mauled on July 1st, the 6th Wisconsin, 84th New York, and 147th New York. They also included regiments from the 11th Corps, the 61st Ohio, 82nd Illinois, and the 45th and 157th New York. These reinforcements arrived during the night, filing into the Union lines and preparing for the next day's fighting. Both sides reinforced their positions during the night. The Confederates consolidated their hold on the lower slopes while the Union troops strengthened their defenses on the upper slopes. The night was filled with the sounds of construction, axes felling trees, shovels digging earth, the murmur of men preparing for what they knew would be a brutal fight at dawn.

[00:24:47]Before sunrise on July 3rd, the battle for Culps Hill resumed. Five Union batteries opened a deadly fire on the Confederate penetration.

[00:24:57]The artillery fire ceased after half an hour and the Confederates renewed their assault.

[00:25:03]The fighting that followed was the most sustained of the entire battle, lasting nearly 7 hours on July 3rd alone.

[00:25:12]One Union soldier said, "The whole hillside seemed enveloped in a blaze." A Maryland Confederate wrote the same.

[00:25:20]Johnson's men attacked three times. Each attack failed. The 12th core units had been reinforced by troops from the First and Sixth Corps, and their position was too strong for the Confederates to take.

[00:25:32]In the last Confederate attacks at perhaps 10:00 a.m., the Stonewall Brigade and Daniels North Carolina Brigade assaulted Green's position from the east. Stewart's brigade advanced over Party Field toward the main hill.

[00:25:46]Both attacks failed dismally. A feudal attack by two Union regiments across the meadow by Spangler Spring against Johnson's left symbolized the end of the fighting. By noon, it was over. Ule's assaults against the Union right had failed. The fighting on Culps Hill was the longest sustained combat of the entire battle. No Union brigade fought longer under direct assault than Green's brigade, and no brigade contributed more to the ultimate Union victory.

[00:26:16]The Confederates were driven from their last tow hold on Culps Hill during the morning of July 3rd. The Union line had held. Why did Green's defense succeed where so many others failed?

[00:26:29]The answer rests on four interconnected pillars. First, the terrain. Culps Hill was ideally suited for defense. Its steep boulder strewn slopes slowed the Confederate advance and provided natural cover for the defenders. The dense woods made it difficult for the Confederates to maintain formation or coordinate their attacks. Rock Creek to the east was a substantial obstacle that had to be crossed by any attacking force.

[00:26:57]Second, engineering.

[00:26:59]Green's breast works were among the most important field fortifications of the Gettysburg campaign. They provided cover from enemy fire, allowed the defenders to conserve ammunition, and multiplied the effectiveness of a small force many times over.

[00:27:15]The Confederates attacking uphill without the benefit of similar works were at a severe disadvantage.

[00:27:21]Third, leadership.

[00:27:24]Green's calm, disciplined command held his brigade together during the most desperate moments of the fighting. He understood the value of prepared positions and was willing to disregard the objections of his superiors to ensure that his men had every possible advantage. Fourth, discipline. Green's men were well- drilled and well- led.

[00:27:45]They had fought at Chancellor'sville and knew what to expect in battle. When the Confederates attacked, they held their fire until the enemy was close, then delivered devastating volleys that broke the Confederate attacks.

[00:27:59]Modern battlefield archaeology has confirmed the importance of Green's position. Recent rehabilitation work on Culps Hill has improved visibility and allowed historians to better understand the tactical situation. The earthworks still survive, a testament to the engineering skill of Green and his men.

[00:28:18]Historians continue to debate how decisive Green's defense was. Some argue that it was the crucial lynchpin of July 2nd that if Culps Hill had fallen, the Union army would have been destroyed.

[00:28:31]Others argue that while Green's stand was important, it was one of many factors that contributed to the Union victory. What is not in dispute is that Green's defense prevented the Confederates from achieving a breakthrough on the Union right flank.

[00:28:45]It preserved the Union Army's position on the high ground. It protected the Baltimore Pike and the Army's line of retreat, and it forced Lee to reconsider his strategy, ultimately leading to the disastrous assault on the Union Center that we know as Pickicket's charge.

[00:29:03]Green's defense had consequences that rippled across the entire battlefield.

[00:29:09]By holding the right flank, Green ensured that the Confederates could not turn the Union position. If Culps Hill had fallen, the Confederates would have been in the rear of the Union Army. They could have cut the Baltimore Pike, severing the supply line and line of retreat. They could have rolled up the Union line. Instead, the Union Army remained in control of the high ground.

[00:29:32]Me's headquarters was never threatened.

[00:29:34]The army's communications and logistics remained intact. Lee's options narrowed.

[00:29:40]The attacks on both flanks had failed.

[00:29:43]Lee concluded that the only remaining option was to attack the Union center.

[00:29:48]The assault that followed, Pickicket's charge, has become the most famous episode of the battle. But it would not have happened if Green had not held Culps Hill. The charge was a gamble, a desperate attempt to break the Union line after the flank attacks had failed.

[00:30:04]It was a gamble that failed. It is important not to overstate the case.

[00:30:09]Green's defense did not win the battle by itself. The Union victory was the result of many factors. The courage of the soldiers, the leadership of officers at all levels, the tactical decisions made by me and his subordinates, and the mistakes made by Lee and his commanders.

[00:30:27]But Green's stand was essential. Without it, the Union Army might have been outflanked and destroyed. Without it, the Battle of Gettysburg might have been a Confederate victory. As historian Charles Fennel wrote, the turning point of the battle occurred on Culps Hill as Confederate forces were stopped. Over the years, several misconceptions have clung to the battle. Perhaps the most persistent myth is that Pickicket's charge decided the battle by itself. The charge was dramatic and visually striking, but it was only one part of a three-day battle. The fighting on July 2nd, including Green's defense of Culps Hill, was at least as important in determining the outcome. Another common misconception is that the fighting on Culps Hill was secondary. In reality, it was the anchor of the Union right flank, the protector of the Baltimore Pike and the key to the entire Union position.

[00:31:22]The fighting there was the longest sustained combat of the entire battle.

[00:31:28]It is also a mistake to assume that Green won the battle alone. His brigade was outnumbered more than 3 to one and his men fought with extraordinary courage. But they were reinforced during the night and other Union units played important roles. Green's stand was essential, but it was not the only factor. The notion that field fortifications played only a minor role is another distortion. Field fortifications were crucial to the Union victory. Culps Hill was the only location where true field works were constructed. Green's breast works allowed his small force to hold off a much larger Confederate force. Finally, the belief that age made Green ineffective belies the very source of his advantage. At 62, Green was the oldest Union general on the field. But his age was not a liability. It was an asset. His decades of experience as a civil engineer gave him an understanding of defensive works that younger officers lacked. His years of leadership had taught him how to command men in the most difficult circumstances.

[00:32:36]Modern scholarship has reshaped our understanding of Culps Hill's importance. Historians like Harry fans have provided detailed tactical accounts that illuminate the decisions made by generals on both sides. The National Park Service has conducted extensive research, including recent rehabilitation work that has improved visibility and understanding.

[00:32:58]What emerges is a picture of a battle far more complex than the popular narrative suggests.

[00:33:05]The fighting on Culps Hill was not a sideshow. It was central to the outcome.

[00:33:10]Green's defense was one of the most consequential actions of the entire war.

[00:33:15]The fighting on Kulps Hill came at a terrible cost. Exact casualty figures vary among historians in part because the battle was so prolonged and confused.

[00:33:27]What is clear is that the Confederates suffered heavily in their attacks on Green's position. Johnson's division lost hundreds of men in the assaults on July 2nd and 3rd. Union casualties were also significant. Green's brigade, though protected by breast works, took heavy losses from Confederate fire. The 60th New York, which bore the brunt of the attacks on July 2nd, suffered relatively few casualties compared to the Confederates, but every loss was keenly felt. In the broader context, the casualties were staggering. The Union Army suffered approximately 23,000 casualties. The Confederates suffered approximately 28,000.

[00:34:09]Only five Union and Confederate brigades sustained 1,000 or more casualties at Gettysburg.

[00:34:16]Cutler's brigade, which assisted Green on Culps Hill, was one of them. The human cost was immense. Thousands laid dead or wounded on the fields around Gettysburg. The dead were buried in makeshift graves, many unmarked. It would take years for the battlefield to recover, but the sacrifice was not in vain. The Union victory, secured in no small part by Green's defense, turned the tide of the war. Lee's army of Northern Virginia would never again mount a major offensive into northern territory. The Confederacy's hopes of foreign recognition were dashed. The war would continue for nearly two more years, but the strategic initiative had passed to the Union. On the evening of July 3rd, the battle was effectively over. Lee had lost. His army was battered, exhausted, and low on ammunition. He had no choice but to retreat.

[00:35:14]The retreat began on July 4th, the same day that Vixsburg surrendered to Ulissiz Srant. The Confederate cause had suffered two devastating blows in a single week. Me pursued cautiously, but the Confederates managed to escape across the PTOAC. The campaign was over.

[00:35:32]Green and his brigade had survived. They had lost many comrades, but they had held the line. Their stand had prevented a Confederate breakthrough that could have changed the outcome of the battle and perhaps the war. Green's contribution was recognized by his contemporaries. He was praised for his engineering skill, his tactical judgment, and his personal courage. But as the years passed, his role was overshadowed. Why did Green's contribution become overshadowed?

[00:36:04]Part of the answer lies in the nature of the fighting. It was not a dramatic open field assault like Pickicket's charge.

[00:36:11]It was a desperate, confused nighttime struggle in dense woods. It lacked the visual drama that captured the public imagination.

[00:36:20]Part of the answer lies in Green's personality. He was not a self-promoter.

[00:36:26]He did not write memoirs or lobby for recognition. He returned to civilian life after the war and resumed his career as a civil engineer. And part of the answer lies in the broader historical narrative.

[00:36:39]The story of Gettysburg became in popular memory the story of Joshua Chamberlain and Little Roundtop of Pickicket's charge of the high tide of the Confederacy.

[00:36:50]Culps Hill was relegated to a footnote.

[00:36:54]In recent decades, historians have begun to reassess Green's contribution.

[00:36:58]Scholars like Harry Fans have provided detailed accounts. Charles Fennel's dissertation makes the case that Green's brigade was primarily responsible for holding the hill and that no Union brigade contributed more to the ultimate victory. The National Park Service has worked to preserve the battlefield and improve visitor understanding.

[00:37:19]Green himself is commemorated at Gettysburg National Military Park. A statue of him stands at the summit of Kulps Hill next to the observation tower. His grave site in Warick, Rhode Island, is marked by a boulder from Culps Hill. A fitting tribute to the man who made that hill his most famous battlefield.

[00:37:40]Green lived long after the war ended. He died on January 28th, 1899 at the age of 97.

[00:37:48]At the time of his death, he was the oldest surviving Union general and the oldest living graduate of West Point. He had lived to see the nation reunited. He had lived to see the Civil War become history. And he had lived to see his own contribution, his defense of Culps Hill, become recognized as one of the most consequential actions of the entire war.

[00:38:10]But Green's legacy extends beyond Gettysburg. His career as a civil engineer helped shape modern America. He built railroads, designed aqueducts, created water systems that made cities habitable. He was one of the founders of the American Society of Civil Engineers.

[00:38:29]His work improved the lives of millions of Americans. In that sense, Green's life was a bridge between two worlds.

[00:38:37]The world of the early American republic, where he was born, and the world of modern industrial America, which he helped to build. He was a man of the 19th century and a man of the future. We began with a comparison.

[00:38:51]Stonewall Jackson at Chancellor'sville, George Green at Gettysburg.

[00:38:57]Jackson's flank march was one of the most daring offensive maneuvers in American military history. It demonstrated the power of audacity, speed, and surprise. It showed that a commander with vision and courage could defeat a larger force by striking where the enemy least expected it.

[00:39:16]Green's stand on Culps Hill was something different. It was not audacious. It was steadfast. It was not offensive. It was defensive.

[00:39:27]It did not rely on surprise. It relied on preparation. But in its own way, Green's defense was just as remarkable.

[00:39:35]Jackson understood that a single vulnerable flank could determine the outcome of an entire battle. Green understood the same thing. But while Jackson exploited a vulnerable flank to achieve victory, Green defended a vulnerable flank to prevent defeat.

[00:39:52]Jackson demonstrated the power of maneuver. Green demonstrated the power of preparation, engineering, and discipline. Jackson showed that a bold offensive could win a battle. Green showed that a determined defense could save an army. Green's stand on Culps Hill remains one of the least celebrated yet most consequential defensive actions of the American Civil War. His brigade, 1400 New Yorkers, held off more than 4,700 Confederates on the evening of July 2nd, 1863.

[00:40:25]They held the line through the night and into the next day, fighting for nearly 7 hours on July 3rd alone. They preserved the Union Army's right flank, protected its supply line, and prevented a Confederate breakthrough that could have changed the outcome of the battle and perhaps the war.

[00:40:45]Green's engineering background gave him an understanding of defensive works that many of his contemporaries lacked. His decision to build breast works despite objections was essential to holding the position. His calm, disciplined leadership held his brigade together.

[00:41:02]At the age of 62, the oldest Union general on the field, Green proved that experience, intelligence, and preparation could be as valuable as youth, audacity, and courage. He was not a flawless hero. He was not an overlooked genius. He was a competent, dedicated officer who did his duty when it mattered most. In doing so, he helped save the Union Army and perhaps the Union itself.

[00:41:32]Today, visitors to Gettysburg National Military Park can walk the slopes of Culps Hill, trace the lines of Green's breast works, and stand at the summit where the 60th New York made its stand.

[00:41:46]They can see the terrain that Green defended and understand why it mattered so much. But too few visitors know Green's story. Too few understand that the fighting on Kulps Hill was the longest sustained combat. Too few realize that without Green's stand, the Union Army might have been destroyed.

[00:42:06]This documentary has attempted to tell that story. It has attempted to restore Green to his proper place in the history of the Battle of Gettysburg.

[00:42:16]It has attempted to show that the engineer who built bridges and aqueducts was also the general who saved an army.

[00:42:24]He was buried in the Green family cemetery in Warwick, Rhode Island, his grave marked by a boulder from Culps Hill. The boulder is a fitting tribute.

[00:42:33]It came from the hill where Green made his stand. It represents the steadfastness, the durability, the unyielding determination that defined his character. It is a reminder that sometimes the most important victories are won not by brilliant maneuvers, but by holding the line.
