The Research Arsenal is proud to be digitizing and adding historical records of Civil War regiments held at the National Archives to our online database so that researchers and historians can access material that previously required a trip to Washington D.C. The 37th Wisconsin Infantry is one of the many regiments that has been added to our database.

Organized late in the war, the 37th Wisconsin Infantry Regiment entered Federal service in 1864 and quickly found itself thrown into some of the most punishing campaigns of the conflict. Often remembered as part of the hard-fighting formations before Petersburg, the regiment’s story is best understood not through statistics alone, but through the voices of the men themselves—men who wrote home from hospitals, from muddy trenches, and from battle lines lit by “a glowing red and angry” sun.

Baptism of Fire Before Petersburg

According to the National Park Service summary of the regiment’s service, the 37th Wisconsin was mustered in during the spring of 1864 and soon assigned to the Army of the Potomac. The regiment joined the grinding Overland Campaign and the subsequent operations against Petersburg, where trench warfare and constant skirmishing became the norm.

The regimental history preserved on Project Gutenberg vividly recounts the regiment’s early encounters with combat. At Cold Harbor and in the initial assaults on Petersburg, the men learned quickly what modern warfare meant. One account describes the approach to battle in stark, almost poetic language—the “sun rose glowing red and angry,” as if presaging the carnage to come. The color of the sky blended with the smoke of artillery and the flash of musketry, until the field seemed wrapped in a haze of fire.

In those early actions, the regiment suffered heavily. Men who had scarcely grown accustomed to army routine found themselves under relentless fire. Letters and reminiscences from the regiment describe the terrifying shriek of shells, the crash of volleys, and the sight of comrades struck down. Yet alongside fear was resolve. One soldier reflected that the line held firm despite the storm, the men loading and firing with mechanical determination even as the ranks thinned.

The siege of Petersburg brought a different kind of suffering. Instead of brief, terrible clashes, the 37th endured weeks and months of exposure in trenches. Accounts in the regimental narrative speak of heat, mud, vermin, and the constant vigilance required in close proximity to Confederate lines. Sharpshooters made even the act of raising one’s head perilous. Nights were filled with fatigue duty, digging, and the hauling of supplies.

Still, the men found ways to adapt. The regimental history preserved on Project Gutenberg makes clear that survival before Petersburg required ingenuity as much as courage. After the first shock of assault, the 37th Wisconsin settled into the exhausting rhythm of siege warfare. The men quickly learned that their safety depended upon the depth of their rifle pits. As one account relates, they “improved their works whenever opportunity offered,” deepening trenches and strengthening parapets until the raw earthworks became something like a second skin. What began as shallow scrapes in the dirt evolved into elaborate lines of protection, with head-logs and traverses carefully arranged against enfilading fire.

The same source describes how the soldiers burrowed into the Virginia soil, fashioning crude but effective shelters. In language both practical and wry, the writer explains that the men constructed “little huts of logs and earth,” covering them with whatever material could be found. These makeshift quarters, half underground and half exposed, offered scant comfort, but they were preferable to open sky under sharpshooter fire. The transformation was striking: volunteers from Wisconsin farms and towns became, in effect, subterranean dwellers. The trench line was no temporary encampment—it was home.

Daily life required constant labor. The regimental narrative emphasizes that nights were seldom restful. Fatigue duty—digging, carrying gabions, strengthening fortifications—filled the dark hours. By day, vigilance was paramount. The opposing lines lay so close that even a careless movement might draw a bullet. One passage notes that a man who exposed himself above the parapet did so “at the peril of his life,” a reminder that routine tasks were never entirely safe.

And yet, humor persisted. The same regimental account, even while describing hardship, adopts a tone of dry resilience. The men learned to treat their earth-covered huts as legitimate residences, however unlikely that might seem. What had once been a “ditch” became, through repetition and necessity, a familiar address. The absurdity of domesticating a trench was not lost on them. In recounting their circumstances, the writer’s understated style suggests the soldiers’ own coping mechanism: if one must live underground, one might as well speak of it matter-of-factly.

Captain George A. Beck’s letter, though written from the relative comfort of Annapolis, underscores the same spirit of endurance. Having been “everywhere so well treated” during his convalescent journey, he affirmed that he could “go back and endure the privations of the camp with a will.” The phrase is revealing. The “privations of the camp” were not abstract—they meant poor rations, exposure, exhaustion, and danger. Yet Beck framed them as burdens willingly borne, sustained by affection for home and faith in the Union cause.

Even the hospital setting, with its “neat cot,” gas lighting, and “clouded Egyptian marble mantle piece,” stood in quiet contrast to the earthworks of Petersburg. Beck’s appreciation for these comforts only highlights what the men at the front lacked. His readiness to return speaks to a shared understanding within the regiment: hardship was temporary; duty was paramount.

“The Sun Rose Glowing Red and Angry”

One particularly evocative description—preserved in later commentary drawing from regimental accounts—captures a morning before battle: “The sun rose glowing red and angry.” The phrase suggests both beauty and menace. For the 37th Wisconsin, dawn often meant renewed danger. As daylight revealed opposing lines, skirmish fire would resume. Artillery, silent in darkness, began again its thunder.

Such imagery reminds us that these were citizen-soldiers trying to comprehend extraordinary violence. Nature itself seemed enlisted in the drama. Red skies, drifting smoke, and the trembling earth became part of their vocabulary of war.

Yet even amid such scenes, the soldiers’ writings return repeatedly to thoughts of home. Captain Beck’s longing for “those… hills, bordering the limpid waters of Mahoning” echoes through other accounts. Streams of boyhood held “precedence” over any historic river encountered in the East. The contrast between peaceful Wisconsin landscapes and Virginia battlefields sharpened both memory and purpose.

Sacrifice and Endurance

The 37th Wisconsin’s losses were severe. The National Park Service notes the regiment’s participation in major operations around Petersburg and its continued service until the war’s closing campaigns. Disease and battle claimed many. Officers and enlisted men alike were wounded or killed.

The Battle of the Crater was a major Civil War engagement on July 30, 1864, during the Siege of Petersburg, where Union forces detonated 8,000 pounds of gunpowder under Confederate lines. The explosion created a 130-foot long, 30-foot deep crater, but the subsequent Union assault failed, resulting in a disastrous Confederate victory with over 5,000 combined casualties.

The explosion created a 130-foot long, 30-foot deep crater, but the subsequent Union assault failed, resulting in a disastrous Confederate victory with over 5,000 combined casualties.

The 37th Wisconsin Infantry Regiment was heavily engaged in the operations surrounding the Battle of the Crater, one of the most desperate and chaotic episodes of the Petersburg campaign. On July 30, 1864, after Union forces detonated a massive mine beneath the Confederate lines, the explosion tore a gaping chasm in the earth and briefly stunned the defenders. The 37th Wisconsin, already hardened by weeks in the trenches, advanced as part of the supporting assaults that followed the blast. Instead of the swift breakthrough many had hoped for, the scene devolved into confusion. The crater itself became a deadly trap—men crowding into its steep sides, struggling to climb out under withering musketry and artillery fire from Confederates who quickly recovered and poured fire into the pit. Of the 250 men of the 37th Wisconsin Infantry who charged into the crater, only 95 walked back out. Over 150 of them had been killed or wounded.

Accounts from the regiment’s history emphasize the intensity and disorder of the fighting. The men faced not only the enemy’s fire but the physical obstacles of broken ground, loose earth, and the suffocating heat of late July. Units became intermingled, commands were difficult to hear, and forward movement stalled. The 37th suffered significant casualties in the effort, a grim testament to the futility of the assault once momentum was lost. The failed attack at the Crater deepened the grim reality of siege warfare for the regiment: bold plans could dissolve in moments, leaving soldiers to endure the grim arithmetic of loss while the lines settled back into the grim persistence of trench fighting before Petersburg.

And yet, as Beck’s letter demonstrates, the men of the 37th often framed their suffering in moral terms. To “endure the privations of the camp” was not merely necessity but duty. The Union, in their eyes, was “a good kindly country,” worth hardship and, if required, life itself.

Firsthand accounts from the regiment do not romanticize war. They speak plainly of exhaustion, fear, and grief. But they also reveal steadfastness. Whether writing from a gas-lit hospital room in Annapolis or from trenches before Petersburg, the soldiers of the 37th Wisconsin bore witness to a conflict that tested body and spirit alike.

In their own words, we see not just a regiment’s movements on a map, but the interior world of men who balanced affection for family with fierce loyalty to country. The red dawns of Virginia, the marble mantels of Annapolis, the muddy lines before Petersburg—all formed chapters in the lived experience of the 37th Wisconsin Infantry.

The Research Arsenal is proud to be digitizing and adding historical records of Civil War regiments held at the National Archives to our online database so that researchers and historians can access material that previously required a trip to Washington D.C. The 5th Minnesota Infantry is one of the many regiments that has been added to our database.

The 5th Minnesota Volunteer Infantry Regiment was organized at Fort Snelling, Minnesota, in spring 1862 in response to President Lincoln’s call for more troops during the American Civil War. It was the last of Minnesota’s early volunteer regiments to be assembled, and its men served with distinction in both frontier conflicts and major campaigns of the Western Theater.

Early Service and the Dakota Conflict

While seven of the regiment’s companies were sent south in May 1862 to join the Union war effort, three companies remained in Minnesota during the U.S.–Dakota War of 1862. These detachments saw action on the frontier — including the ambush at Redwood Ferry, the defense of Fort Ridgely, and the protection of Fort Abercrombie — engaging Dakota forces during the outbreak of hostilities.

Joining the Western Campaigns

Once reunited in Mississippi by early 1863, the 5th Minnesota became part of the Army of the Mississippi (later the Army of the Tennessee). Their first significant combat was at the Battle of Farmington shortly after arriving at Corinth, Mississippi, followed by involvement in the Siege of Corinth and other actions like the Battle of Iuka. At Corinth, they played a key role in closing a breach in Union lines and recapturing artillery.

The regiment participated in General Ulysses S. Grant’s Vicksburg Campaign, fighting at Jackson and contributing to operations that culminated in the surrender of Vicksburg on July 4, 1863, a major strategic victory for the Union. Soon after, the men who re-enlisted earned the designation “Veteran Volunteers,” reflecting their experience and commitment.

1864–1865: Continued Fighting

In March through May of 1864 the regiment took part in the Red River Campaign in Louisiana — an ultimately unsuccessful Union effort — before rejoining Union forces in the pursuit of Confederate General John Bell Hood through Tennessee.

From August 29 – December 2, 1864, the 5th Minnesota marched hundreds of miles pursuing Confederate General Sterling Price’s army through Arkansas, Missouri, Kansas, and the Indian Territory. Conditions during the expedition were severe for the Union army, as Col. Hubbard described in the regiment’s narrative:

“This was, all things considered, the hardest campaign it [the regiment] made during the war. The route lay through almost impenetrable cypress swamps and over unused mountain roads, washed by continuous rains down to their rocky beds. Severe storms prevailed much of the time, and the men often lay down at night, drenched, sore, weary and hungry, feeling that they would never be able to rise to their feet again. It was developed after the command had been out several days that its supply train was loaded with moldy and decayed hard bread, refuse stores issued by the commissary at Little Rock. In consequence of this the army was early put upon half-rations, then one-third, and much of that unfit to eat. The men became nearly starved, and driven to that extreme that they sought for nourishment in the bark of sassafras boughs and beech leaves, which the forest trees afforded. The country was largely uninhabited, and hence afforded nothing upon which an army could subsist.”

At the Battle of Nashville in December 1864, the 5th Minnesota helped break Confederate lines, though they suffered significant casualties. “On the second day of the battle the men advanced across an open field towards the Confederate forces. They suffered a withering fire, and 106 men were killed or wounded. The battle, however, was a resounding Union success. During the battle, the Fifth’s Lieutenant Thomas P. Gere captured the flag of the Fourth Mississippi Regiment.”

In early 1865, the regiment was involved in the campaign against Mobile, Alabama, helping secure positions around the city. With the war winding down, the 5th Minnesota was mustered out of service on September 6, 1865, at Demopolis, Alabama, and returned to Minnesota later that month.

Legacy

Over nearly four years of service, the 5th Minnesota fought in numerous battles and campaigns, from frontier duty in Minnesota to some of the most consequential operations in the Western Theater. Their service exemplified the significant contributions of Midwestern volunteer regiments in achieving Union victory.

Saddles, Carbines, and First Shots: The Story of the 8th Illinois Cavalry

When the Civil War erupted in 1861, men across Illinois answered President Lincoln’s call. Among them, those who enlisted in the 8th Illinois Cavalry would go on to carve out a remarkable history, full of daring raids, brushes with famous Confederate commanders, and even a claim to one of the most significant “firsts” of the war. Though not always in the spotlight, their story is one worth remembering—both for its heroism and for the human moments that shine through.

Early Days: A Regiment with an Edge

The 8th Illinois Cavalry was mustered into service in September 1861, pulling in farmers, merchants, clerks, and adventurous young men from across northern Illinois. They were unusual from the start, being issued breech-loading carbines, which gave them a faster rate of fire than many of their Confederate foes.

One soldier later recalled:

“Our breech-loaders gave us the power to strike quick and fall back before the enemy’s slow rifles could answer.”

That technological edge made the regiment a thorn in the Confederacy’s side from their first campaigns.

Gettysburg: The Shot That Sparked the Battle

The regiment’s most enduring claim to fame came on the morning of July 1, 1863, at Gettysburg. Lieutenant Marcellus E. Jones, borrowing a carbine from Sergeant Levi Shafer, fired the first shot of the battle.

Jones later reflected:

“I did not think of making history, only of doing my duty.”

That single shot helped set in motion the Union Army’s defense of the Pennsylvania crossroads town, and the regiment continued to screen, scout, and skirmish throughout the bloody three-day battle.

Soldiers’ Stories: Faces of the Regiment

Col. John Farnsworth – The Politician-Turned-Cavalryman

John Farnsworth, the regiment’s first commander, was a lawyer and politician before the war. Known for his fiery speeches in Congress, he traded words for weapons when he helped raise the 8th Illinois. Though not always a tactician of genius, Farnsworth’s charisma and drive helped mold the regiment in its early days.

Lt. Marcellus E. Jones – The Man of the First Shot

Jones’ name is forever tied to Gettysburg. What’s less known is that after the war, he returned to Illinois and became a judge. He attended veterans’ reunions faithfully, always modest about his place in history.

Capt. William Medill – A Fallen Leader

One of the regiment’s most poignant stories is that of Capt. William Medill, who was killed at the Battle of Malvern Hill in 1862. Medill was the brother of Chicago Tribune editor Joseph Medill, and his loss struck both the regiment and his influential family deeply. His death was a reminder that the war’s reach extended from battlefields to newsrooms and parlors back home.

Pvt. William F. Lyons – The Camp Humorist

Not every legacy was written in blood. Private William Lyons became known in the regiment for his jokes and antics. One comrade remembered:

“Lyons could turn the gloomiest camp into laughter. Even after a twenty-mile march, he’d find some jest to make us forget our sore feet.”
His humor was more than entertainment—it was survival for men who faced constant fatigue and danger.

Sgt. Levi Shafer – The Lender of the Carbine

Often overlooked, Sergeant Shafer deserves credit as the man whose carbine fired the first shot at Gettysburg—though in another’s hands. Accounts suggest he joked about it later, saying Jones “borrowed the honor along with my gun.”

Facing Stonewall Jackson and J.E.B. Stuart

The 8th Illinois crossed paths with some of the Confederacy’s greatest commanders. They tangled with Stonewall Jackson’s forces in the Shenandoah Valley, and often sparred with J.E.B. Stuart’s cavalry.

One trooper wrote of the nerves these encounters demanded:

“To fight Stuart was to fight the wind. One moment we thought him far off, the next he was upon our flank.”

Against such opponents, the Illinois men learned to be cautious, quick, and clever.

Camp Life: Humor Amid Hardship

Cavalry life was grueling. Horses needed care before the men themselves, food was often short, and disease lurked everywhere. Yet soldiers made the best of it.

One diary notes:

“We staged a mock parade, strutting like peacocks until even the colonel laughed.”

Moments like these carried the men through endless nights in fields and barns, when war felt far from glorious.

Raids, Risks, and Narrow Escapes

The regiment became adept at raiding behind enemy lines—cutting telegraph wires, seizing supplies, and spreading confusion. But raids were perilous.

As one officer admitted:

“It was a game of hours. Delay meant capture, haste meant ruin of our mounts. Raiding was not grand, but desperate work.”

The 8th Illinois survived many close calls, often escaping capture by sheer grit.

The Toll of War

The price was high. Disease, exhaustion, and combat steadily thinned their ranks. Soldiers mourned not just their comrades but also their horses, with whom they shared a unique bond.

One letter home captures this attachment:

“I pray my horse may live to see Illinois pasture. He has borne me as true as any friend.”

These words show how intertwined man and mount were in the cavalry experience.

After the War: Guardians of Memory

When the war ended at Appomattox, the 8th Illinois Cavalry returned home with honor. But they did not let their story fade. Veterans became active in preserving battlefields, attending reunions, and sharing their history.

At one gathering, a veteran declared:

“We fired the first shot, aye, but we also bore the long burden. Let no man forget that Illinois riders held fast from first to last.”

The 8th Illinois Cavalry’s history is more than a string of dates and battles—it’s the lived experience of men like Jones, Medill, Lyons, and Shafer. Some made history in famous moments, others in laughter or sacrifice, but together they formed a regiment that left its mark on the Civil War.

Their story reminds us that behind every regiment number are names, faces, and lives—ordinary men who carried themselves with extraordinary courage. And sometimes, history itself can turn on the squeeze of a trigger, on a borrowed carbine, on a quiet Pennsylvania morning.
