The 1st Wisconsin Cavalry Regiment During the Civil War

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 1st Wisconsin Cavalry is one of the many regiments that has been added to our database.
The 1st Wisconsin Cavalry Regiment served throughout the Civil War, participating in campaigns across the Western Theater and eventually becoming part of the Union cavalry forces operating in the final months of the conflict. From its early days of organization in Wisconsin to its operations in Tennessee, Alabama, Georgia, and the pursuit of Confederate President Jefferson Davis, the regiment experienced a remarkable range of military service.
The experiences of its soldiers were not limited to battlefield engagements. Letters home reveal the frustrations, rivalries, uncertainties, and everyday complications of military life. One particularly entertaining account comes from Private Ira Adams, who wrote to his friend Lizzie Barnes in March 1862 while confined to the regimental guardhouse. His letter offers a glimpse into the personalities and internal disagreements that could make life in a Civil War regiment almost as complicated as life on the battlefield.
Organization and Early Service
The organization of the 1st Wisconsin Cavalry began in the summer of 1861, when Wisconsin received authorization to raise a cavalry regiment. Initially, the state was authorized to recruit four companies, but that number was increased first to six companies and eventually to a full regiment of twelve companies.
Recruiting and organization initially took place at Camp Fremont in Ripon, Wisconsin. On November 22, 1861, the rendezvous was moved to Camp Harvey in Kenosha, where the regiment completed its organization. The last company was mustered into Federal service on March 8, 1862, and the regiment departed Wisconsin on March 17, bound for St. Louis, Missouri, before proceeding to Cape Girardeau.
The regiment’s early service involved considerable movement and the separation of its companies into smaller detachments. From Missouri, companies were sent to various locations in Missouri and Arkansas, where they performed military duties until the spring of 1863.
An interesting glimpse into the regiment’s earliest days comes from a letter written by Ira Adams to his friend Lizzie Barnes on March 12, 1862, while the regiment was still at Camp Harvey. Adams’s letter reveals that the regiment was experiencing some internal disagreements even before leaving Wisconsin. He explained that Governor Harvey had declared the previous company officer elections void and ordered a new election. Adams, who had been seeking a majority position, lost the election, which he attributed to a “combined force of office seekers.”
His troubles did not end there. With the regiment preparing to leave, Adams wanted to travel to Mill to retrieve some belongings he had left behind. After failing to obtain the necessary pass from the major, he secured permission to go downtown and decided to take the train instead. Unfortunately, a guard had been stationed at the depot to prevent soldiers from deserting. When Adams was seen boarding the train, Captain Eggleston reported him as a deserter. The major immediately sent a telegraph message to the police in Mill, instructing them to arrest Adams, place him in irons, and return him to camp.
Adams, however, had anticipated trouble and was careful when he arrived in Mill. The police eventually reported that the supposed deserter was not on the train, creating considerable excitement back at camp. When Adams returned to camp, he was met by Sergeant Gould and two armed soldiers who had been sent to apprehend him. He surrendered without resistance and was placed under arrest. He described his reception by the major with considerable sarcasm:
“I had not been in the tent long before he came up to me with the dignity of Prince Napoleon and said that he did not meet any deserters in his tent and I will oblige him very much if I would leave.”
The situation deteriorated further when Adams was ordered to the guardhouse for an alleged attempt to escape and insubordination. Fortunately, Colonel Edward Daniels eventually arrived from Washington and issued an order for his release. Adams closed his account by telling Lizzie that he intended to leave the regiment within a few days, possibly enlisting in the regular army for five years to serve in the Colorado Territory. His letter provides a wonderfully personal account of the disagreements and disciplinary problems that could occur within a newly organized regiment, even before its soldiers had experienced combat.
Service in Tennessee and the Battle of Chickamauga
In late May 1863, the 1st Wisconsin Cavalry was transferred to Middle Tennessee, arriving in Nashville on June 14. It was assigned to the Cavalry Corps of the Army of the Cumberland, with which it would serve for the remainder of the war. During the summer of 1863, the regiment participated in the Union advance toward Chattanooga, Tennessee. This campaign culminated in the Battle of Chickamauga, fought September 19–20, 1863. At Chickamauga, the 1st Wisconsin Cavalry served on the extreme right of the Union line. The battle resulted in a Confederate victory and forced the Union Army of the Cumberland to withdraw to Chattanooga, where it was subsequently besieged.
Following Chickamauga, the regiment continued operating throughout the region, performing the varied duties expected of cavalry. Its soldiers guarded wagon trains, protected lines of communication, conducted reconnaissance, and frequently encountered Confederate forces. These assignments required constant movement and kept the regiment actively engaged even when it was not participating in a major battle.
The Atlanta Campaign and Operations in Tennessee
When General William T. Sherman began his Atlanta Campaign in May 1864, the 1st Wisconsin Cavalry was assigned to the Cavalry Corps accompanying his army. The campaign lasted from May through September 1864, as Union forces pushed southward through Georgia toward Atlanta. Cavalry regiments played an important role in these operations, scouting enemy positions, protecting supply lines, screening the movements of infantry, and disrupting Confederate communications.
The 1st Wisconsin participated in the campaign and was almost constantly on the move. Its service included operations associated with Rocky Face Ridge, Resaca, and New Hope Church. The campaign came at considerable cost to the regiment’s leadership. Lieutenant Colonel William H. Torrey, who had served as an acting commander, was killed while commanding the brigade near Atlanta on July 30, 1864. Major Nathan Paine, who had also served as acting commander, had been killed just two days earlier, on July 28.
Colonel Oscar H. La Grange commanded the regiment for much of this period, although he spent considerable time commanding the brigade. Lieutenant Colonel Henry Harnden eventually assumed acting command of the regiment in October 1864. Following the surrender of Atlanta, the 1st Wisconsin accompanied Union forces sent in pursuit of Confederate General John Bell Hood, whose army had moved into Middle Tennessee.
The regiment participated in operations against Hood’s forces, which culminated in the Confederate defeats at Franklin on November 30 and Nashville on December 15–16, 1864. Following the Battle of Nashville, the remnants of Hood’s army retreated southward, pursued by Union cavalry under Major General James H. Wilson. The 1st Wisconsin continued its operations in pursuit of the retreating Confederates, pushing into Alabama.
Wilson’s Raid and the Capture of Jefferson Davis
The final months of the war brought the 1st Wisconsin Cavalry into one of the most famous episodes in its history: the capture of Confederate President Jefferson Davis. In the spring of 1865, Major General James H. Wilson organized a massive cavalry raid through Alabama and Georgia. Beginning on March 11, Wilson’s forces crossed the Tennessee River and advanced into the Deep South. The campaign resulted in the defeat of Confederate cavalry under Nathan Bedford Forrest and the capture of several important Southern cities, including Selma, Montgomery, Columbus, West Point, and Macon.
According to Colonel Henry Harnden’s 1898 account, The Capture of Jefferson Davis; A Narrative of the Part Taken by Wisconsin Troops, the 1st Wisconsin Cavalry played a prominent role in these operations. After Wilson’s forces reached Macon, Georgia, on April 20, 1865, the regiment remained in the area. On the evening of May 6, Harnden received orders to report to headquarters. General J. G. Croxton informed him that Jefferson Davis was believed to be moving through South Carolina toward Georgia, accompanied by members of his cabinet and an escort of several hundred men.
Harnden was selected to lead a detachment of 150 men from the 1st Wisconsin Cavalry in pursuit of Davis. He was instructed to leave immediately without waiting for additional rations. Before departing, Harnden questioned whether 150 men would be sufficient for the mission. He was assured that General Wilson believed the number adequate, particularly because Davis’s escort was reportedly demoralized and poorly equipped.
The detachment left Macon around sunset and began moving toward Savannah. Harnden initially kept the purpose of the expedition secret from his men. After they had marched through the night and reached the vicinity of Dublin, Georgia, he explained their mission and warned them that they might encounter a much larger Confederate force. He later recalled that his men responded with cheers. At Dublin, Harnden began gathering information about Davis’s movements. He initially received little assistance from the local population, but a Black man who approached him during the night provided the crucial information. The man reported that Davis and his party had passed through Dublin earlier that day, crossing the river and traveling south.
Harnden later credited this information with keeping the Wisconsin detachment on the correct trail. Without it, he believed his men might have continued toward Savannah, allowing Davis to escape. The pursuit continued through difficult terrain, dense pine forests, heavy rain, and flooded swamps. Harnden’s men were frequently short of food, and their horses were pushed through exhausting conditions. At one point, they crossed miles of swamp water that rose as high as their saddles.
On May 9, the Wisconsin detachment reached Abbeville, Georgia, where Harnden encountered Lieutenant Colonel Pritchard of the 4th Michigan Cavalry. Pritchard was also searching for Davis, although the two officers were unaware of how close they were to the Confederate party. Harnden shared the information he had gathered, explaining that Davis had crossed the Ocmulgee River and was believed to be heading toward Irwinsville. The two commands then continued their separate movements in pursuit.
Early on the morning of May 10, 1865, Harnden’s advance guard encountered Confederate pickets near Irwinsville. Gunfire erupted, and the Wisconsin soldiers engaged what they believed to be an enemy force. The situation became even more confusing when a second group of mounted men approached. Harnden ordered his men to fire their repeating Spencer carbines, and the opposing force began to fall into confusion.
Just as Harnden was preparing to order a saber charge, Sergeant Horr reported that the soldiers they were fighting were actually members of the 4th Michigan Cavalry. The two Union detachments had mistaken one another for Confederates in the darkness. The unfortunate encounter resulted in the deaths of two Michigan soldiers, along with several wounded men. Three Wisconsin soldiers were wounded, but none were killed.
After the firing stopped, Harnden and Pritchard rode together into the Confederate camp, which was located only a short distance away. There they encountered John H. Reagan, the former Confederate Postmaster General, who informed them that Jefferson Davis had finally been captured. Harnden asked Reagan to identify Davis. Pointing toward a tall, elderly gentleman nearby, Reagan indicated that he was the former Confederate president. Harnden approached and asked whether the man was Mr. Davis. The response was direct: “Yes,” he replied, “I am President Davis.” The capture had been accomplished.
The capture, however, was not without controversy. Harnden’s account describes the confusion surrounding the competing claims of the Wisconsin and Michigan cavalrymen. Initially, the $100,000 reward offered for Davis’s capture was awarded to the 4th Michigan Cavalry. This decision was challenged because most of that regiment had been approximately twenty-five miles away when the capture occurred.
Congress eventually appointed a committee to investigate the matter. The committee reversed the original award, deciding that the men actually present from both regiments should share the reward according to their respective rank and pay. Harnden emphasized that the Wisconsin soldiers had played an essential role in locating and pursuing Davis, while the Michigan soldiers had also participated in the final encounter.
Harnden’s narrative provides a particularly interesting firsthand perspective on the expedition, including the difficult conditions endured by the men. He praised their conduct throughout the seven-day pursuit, noting that they marched through heat and blinding rain, often with almost nothing to eat and very little rest. Despite their exhaustion and the possibility of encountering a much larger enemy force, he recalled that the men never complained.
He concluded his tribute by writing:
“Their only thought was, it is duty.”
The capture of Jefferson Davis was one of the final notable episodes of the Civil War, and the 1st Wisconsin Cavalry’s participation ensured that the regiment would have a place in the story of the Confederacy’s collapse.
The End of the War and Muster Out
Following the capture of Davis, the 1st Wisconsin Cavalry was transferred to Nashville, Tennessee, where it remained until being mustered out of Federal service on July 19, 1865. The regiment subsequently returned to Madison, Wisconsin, where it was disbanded. During its service, the regiment had recruited an initial 1,124 officers and enlisted men. An additional 1,417 men were recruited as replacements, bringing the total number of men who served in the regiment to 2,541. The cost of that service was considerable. Six officers and 67 enlisted men were killed or mortally wounded, while another seven officers and 321 enlisted men died from disease. In total, the regiment lost 401 men during the war.
The regiment also left behind a notable piece of its history in the form of its guidon. According to the Wisconsin Veterans Museum, the 1st Wisconsin Cavalry’s guidon was the first flag raised over the Confederate Capitol building in Montgomery, Alabama, on April 12, 1865. The museum attributes the raising of the guidon to Captain Stephen V. Shipman, based on information preserved by a descendant who had access to his diary.

From its organization at Camp Harvey to its service in the major campaigns of the Western Theater and its participation in the pursuit of Jefferson Davis, the 1st Wisconsin Cavalry experienced nearly every aspect of the Union Army’s war in the West. Its soldiers endured long marches, difficult campaigns, disease, and the loss of comrades, ultimately serving until the final months of the conflict. The regiment’s history is also preserved through the individual experiences of its soldiers. Ira Adams’s amusing but revealing letter from the guardhouse in 1862 and Henry Harnden’s account of the pursuit of Jefferson Davis in 1865 illustrate just how much could change over the course of four years of military service.
