During the American Civil War, the Union Army referred to the United States Army, the land force that fought to preserve the Union of the collective states. Also known as the Federal Army, it proved essential to the preservation of the United States as a working, viable republic.
The Union Army was made up of the permanent regular army of the United States, but further fortified, augmented, and strengthened by the many temporary units of dedicated volunteers as well as including those who were drafted in to service as conscripts. To this end, the Union Army fought and ultimately triumphed over the efforts of the Confederate States Army in the American Civil War.
Over the course of the war, 2,128,948 men enlisted in the Union Army,including 178,895 colored troops; 25% of the white men who served were foreign-born. Of these soldiers, 596,670 were killed, wounded or went missing. The initial call-up was for just three months, after which many of these men chose to reenlist for an additional three years.
When the American Civil War began in April 1861, there were only 16,367 men in the U.S. Army, including 1,108 commissioned officers. Approximately 20% of these officers, most of them Southerners, resigned choosing to tie their lives and fortunes to the Army of the Confederacy.
In addition, almost 200 West Point graduates who had previously left the Army, including Ulysses S. Grant, William Tecumseh Sherman, and Braxton Bragg, returned to service at the outbreak of the war. This group's loyalties were far more sharply divided, with 92 donning Confederate gray and 102 putting on the blue of the Union Army. The U.S. Army consisted of ten regiments of infantry, four of artillery, two of cavalry, two of dragoons, and three of mounted infantry. The regiments were scattered widely. Of the 197 companies in the army, 179 occupied 79 isolated posts in the West, and the remaining 18 manned garrisons east of the Mississippi River, mostly along the Canada–United States border and on the Atlantic coast.
With the Southern slave states declaring secession from the Union, and with this drastic shortage of men in the army, President Abraham Lincoln called on the states to raise a force of 75,000 men for three months to put down this subversive insurrection. Lincoln's call forced the border states to choose sides, and four seceded, making the Confederacy eleven states strong. It turned out that the war itself proved to be much longer and far more extensive in scope and scale than anyone on either side, Union North or Confederate South, expected or even imagined at the outset on the date of July 22, 1861. That was the day that Congress initially approved and authorized subsidy to allow and support a volunteer army of up to 500,000 men to the cause.
The call for volunteers initially was easily met by patriotic Northerners, abolitionists, and even immigrants who enlisted for a steady income and meals. Over 10,000 Germans in New York and Pennsylvania immediately responded to Lincoln's call, and the French were also quick to volunteer. As more men were needed, however, the number of volunteers fell and both money bounties and forced conscription had to be turned to. Nevertheless, between April 1861 and April 1865, at least 2,128,948 men served in the Union Army, of whom the majority were volunteers.
It is a misconception that the South held an advantage because of the large percentage of professional officers who resigned to join the Confederate army. At the start of the war, there were 824 graduates of the U.S. Military Academy on the active list; of these, 296 resigned or were dismissed, and 184 of those became Confederate officers. Of the approximately 900 West Point graduates who were then civilians, 400 returned to the Union Army and 99 to the Confederate. Therefore, the ratio of Union to Confederate professional officers was 642 to 283.(One of the resigning officers was Robert E. Lee, who had initially been offered the assignment as commander of a field army to suppress the rebellion. Lee disapproved of secession, but refused to bear arms against his native state, Virginia, and resigned to accept the position as commander of Virginian C.S. forces. He eventually became the commander of the Confederate army.) The South did have the advantage of other military colleges, such as The Citadel and Virginia Military Institute, but they produced fewer officers. Though officers were able to resign, enlisted soldiers did not have this right; which meant that they usually had to either desert or wait until their enlistment term was over in order to join the Confederate States Army. While the total number of those is unknown, only 26 enlisted men and non-commissioned officers of the regular army are known to have legally left the army to join the Confederate army when the war began.
The Union Army was composed of numerous organizations, which were generally organized geographically.
Each of these armies was usually commanded by a major general. Typically, the Department or District commander also had field command of the army of the same name, but some conflicts within the ranks occurred when this was not true, particularly when an army crossed a geographic boundary.
The regular army, the permanent United States Army, was intermixed into various formations of the Union Army, forming a cadre of experienced and skilled troops. They were regarded by many as elite troops and often held in reserve during battles in case of emergencies. This force was quite small compared to the massive state-raised volunteer forces that comprised the bulk of the Union Army.
Rough unit sizes for Union combat units during the war:
Soldiers were organized by military specialty. The combat arms included infantry, cavalry, artillery, and other such smaller organizations such as the United States Marine Corps, which, at some times, was detached from its navy counterpart for land based operations. The Signal Corps was created and deployed for the first time, through the leadership of Albert J. Myer.
Below major units like armies, soldiers were organized mainly into regiments, the main fighting unit with which a soldier would march and be deployed, commanded by a colonel, lieutenant colonel, or possibly a major. According to William J. Hardee's "Rifle and Light Infantry Tactics" (1855), the primary tactics for riflemen and light infantry in use immediately prior and during the war, there would typically be, in each regiment, ten companies, each commanded by a captain, and deployed according to the ranks of captains. Some units only had between four and eight companies and were generally known as battalions.Regiments were almost always raised within a single state, and were generally referred by number and state, e.g. 54th Massachusetts, 20th Maine, etc.
Regiments were usually grouped into brigades under the command of a brigadier general. However, brigades were changed easily as the situation demanded; under the regimental system the regiment was the main permanent grouping. Brigades were usually formed once regiments reached the battlefield, according to where the regiment might be deployed, and alongside which other regiments.
Several men served as generals-in-chief of the Union Army throughout its existence:
The gap from March 11 to July 23, 1862, was filled with direct control of the army by President Lincoln and United States Secretary of War Edwin M. Stanton, with the help of an unofficial "War Board" that was established on March 17, 1862. The board consisted of Ethan A. Hitchcock, the chairman, with Department of War bureau chiefs Lorenzo Thomas, Montgomery C. Meigs, Joseph G. Totten, James W. Ripley, and Joseph P. Taylor.
Scott was an elderly veteran of the War of 1812 and the Mexican–American War and could not perform his duties effectively. His successor, Maj. Gen. McClellan, built and trained the massive Union Army of the Potomac, the primary fighting force in the Eastern Theater. Although he was popular among the soldiers, McClellan was relieved from his position as general-in-chief because of his overcautious strategy and his contentious relationship with his commander-in-chief, President Lincoln. (He remained commander of the Army of the Potomac through the Peninsula Campaign and the Battle of Antietam.) His replacement, Major General Henry W. Halleck, had a successful record in the Western Theater, but was more of an administrator than a strategic planner and commander.
Ulysses S. Grant was the final commander of the Union Army. He was famous for his victories in the West when he was appointed lieutenant general and general-in-chief of the Union Army in March 1864. Grant supervised the Army of the Potomac (which was formally led by his subordinate, Maj. Gen. George G. Meade) in delivering the final blows to the Confederacy by engaging Confederate forces in many fierce battles in Virginia, the Overland Campaign, conducting a war of attrition that the larger Union Army was able to survive better than its opponent. Grant laid siege to Lee's army at Petersburg, Virginia, and eventually captured Richmond, the capital of the Confederacy. He developed the strategy of coordinated simultaneous thrusts against wide portions of the Confederacy, most importantly the Georgia and Carolinas Campaigns of William Tecumseh Sherman and the Shenandoah Valley campaign of Philip Sheridan. These campaigns were characterized by another strategic notion of Grant's-better known as total war —denying the enemy access to resources needed to continue the war by widespread destruction of its factories and farms along the paths of the invading Union armies.
Grant had critics who complained about the high numbers of casualties that the Union Army suffered while he was in charge, but Lincoln would not replace Grant, because, in Lincoln's words: "I cannot spare this man. He fights."
Among memorable field leaders of the army were Nathaniel Lyon (first Union general to be killed in battle during the war), William Rosecrans, George Henry Thomas and William Tecumseh Sherman. Others, of lesser competence, included Benjamin F. Butler.
The decisive victories by Grant and Sherman resulted in the surrender of the major Confederate armies. The first and most significant was on April 9, 1865, when Robert E. Lee surrendered the Army of Northern Virginia to Grant at Appomattox Court House. Although there were other Confederate armies that surrendered in the following weeks, such as Joseph E. Johnston's in North Carolina, this date was nevertheless symbolic of the end of the bloodiest war in American history, the end of the Confederate States of America, and the beginning of the slow process of Reconstruction.
In his 1997 book examining the motivations of the American Civil War's soldiers, For Cause and Comrades, historian James M. McPherson states that Union soldiers fought to preserve the United States, as well as to end slavery, stating that:
While restoration of the Union was the main goal for which they fought, they became convinced that this goal was unattainable without striking against slavery.— James M. McPherson, For Cause and Comrades: Why Men Fought in the Civil War , (1997), p. 118, emphasis added.
McPherson states that witnessing the slave system of the Confederacy first-hand also strengthened the anti-slavery views of Union soldiers,who were appalled by its brutality. He stated that "Experience in the South reinforced the antislavery sentiments of many soldiers." One Pennsylvanian Union soldier spoke to a slave woman whose husband was whipped, and was appalled by what she had to tell him of slavery. He stated that "I thought I had hated slavery as much as possible before I came here, but here, where I can see some of its workings, I am more than ever convinced of the cruelty and inhumanity of the system."
The Union Army was composed of many different ethnic groups, including large numbers of immigrants. About 25% of the white men who served in the Union Army were foreign-born. [ citation needed ]. About 200,000 soldiers and sailors were born in Ireland. Although some soldiers came from as far away as Malta, Italy, India, and Russia, most of the remaining foreign-born soldiers came from Great Britain and Canada.
|1,000,000||45.4||Native-born white Americans.|
|210,000||9.5||African-American. Half were freedmen who lived in the North, and half were ex-slaves from the South. They served under mainly white officers in more than 160 "colored" regiments and in Federal U.S. regiments organized as the United States Colored Troops (USCT).|

Many immigrant soldiers formed their own regiments, such as the Irish Brigade (69th New York, 63rd New York, 88th New York, 28th Massachusetts, 116th Pennsylvania); the Swiss Rifles (15th Missouri); the Gardes de Lafayette (55th New York); the Garibaldi Guard (39th New York); the Martinez Militia (1st New Mexico); the Polish Legion (58th New York); the German Rangers; Sigel Rifles (52nd New York, inheriting the 7th); the Cameron Highlanders (79th New York Volunteer Infantry); and the Scandinavian Regiment (15th Wisconsin). But for the most part, the foreign-born soldiers were scattered as individuals throughout units.
For comparison, the Confederate Army was not very diverse: 91% of Confederate soldiers were native born white men and only 9% were foreign-born white men, Irish being the largest group with others including Germans, French, Mexicans (though most of them simply happened to have been born when the Southwest was still part of Mexico), and British. Some Confederate propaganda condemned foreign-born soldiers in the Union Army, likening them to the hated Hessians of the American Revolution. Also, a relatively small number of Native Americans (Cherokee, Chickasaw, Choctaw, and Creek) fought for the Confederacy.
Various organizational and administrative issues arose during the war, which had a major effect on subsequent military procedures.
The inclusion of blacks as combat soldiers became a major issue. Eventually, it was realized, especially after the valiant effort of the 54th Massachusetts Volunteer Infantry in the Battle of Fort Wagner, that blacks were fully able to serve as competent and reliable soldiers. This was partly due to the efforts of Robert Smalls, who, while still a slave, won fame by defecting from the Confederacy, and bringing a Confederate transport ship which he was piloting. He later met with Edwin Stanton, Secretary of War, to argue for including blacks in combat units. This led to the formation of the first combat unit for black soldiers, the 1st South Carolina Volunteers. Regiments for black soldiers were eventually referred to as United States Colored Troops. Black Soldiers were paid less than white Soldiers until late in the war and were, in general, treated harshly.
Battlefield supplies were a major problem. They were greatly improved by new techniques in preserving food and other perishables, and in transport by railroad. General Montgomery C. Meigs was one of the most important Union Army leaders in this field.
The Civil War drove many innovations in military tactics.W. J. Hardee published the first revised infantry tactics for use with modern rifles in 1855. However, even these tactics proved ineffective in combat, as it involved massed volley fire, in which entire units (primarily regiments) would fire simultaneously. These tactics had not been tested before in actual combat, and the commanders of these units would post their soldiers at incredibly close range, compared to the range of the rifled musket, which led to very high mortality rates. In a sense, the weapons had evolved beyond the tactics, which would soon change as the war drew to a close. Military railways, occasionally used in earlier wars, provided mass movement of troops. The electric telegraph was used by both sides, which enabled political and senior military leaders to pass orders to and receive reports from commanders in the field.
There were many other innovations brought by necessity. Generals were forced to reexamine the offensive minded tactics developed during the Mexican–American War where attackers could mass to within 100 yards of the defensive lines, the maximum effective range of smoothbore muskets. Attackers would have to endure one volley of inaccurate smoothbore musket fire before they could close with the defenders. But by the Civil War, the smoothbores had been replaced with rifled muskets, using the quick loadable minié ball, with accurate ranges up to 900 yards. Defense now dominated the battlefield. Now attackers, whether advancing in ordered lines or by rushes, were subjected to three or four aimed volleys before they could get among the defenders. This made offensive tactics that were successful only 20 years before nearly obsolete.
Desertion was a major problem for both sides. The daily hardships of war, forced marches, thirst, suffocating heat, disease, delay in pay, solicitude for family, impatience at the monotony and futility of inactive service, panic on the eve of battle, the sense of war-weariness, the lack of confidence in commanders, and the discouragement of defeat (especially early on for the Union Army), all tended to lower the morale of the Union Army and to increase desertion.
In 1861 and 1862, the war was going badly for the Union Army and there were, by some counts, 180,000 desertions. In 1863 and 1864, the bitterest two years of the war, the Union Army suffered over 200 desertions every day, for a total of 150,000 desertions during those two years. This puts the total number of desertions from the Union Army during the four years of the war at nearly 350,000. Using these numbers, 15% of Union soldiers deserted during the war. Official numbers put the number of deserters from the Union Army at 200,000 for the entire war, or about 8% of Union Army soldiers. Since desertion is defined as being AWOL for 30 or more days and some soldiers returned within that time period, as well as some deserters being labeled missing-in-action or vice versa, accurate counts are difficult to determine. Many historians estimate the "real" desertion rate in the Union Army as between 9–12%.About 1 out of 3 deserters returned to their regiments, either voluntarily or after being arrested and being sent back. Many of the desertions were by "professional" bounty men, men who would enlist to collect the often large cash bonuses and then desert at the earliest opportunity to do the same elsewhere. If not caught and executed, it could prove a very lucrative criminal enterprise.
The Irish were the main participants in the famous "New York Draft riots" of 1863.Stirred up by the instigating rhetoric of Democratic politicians, the Irish had shown the strongest support for Southern aims prior to the start of the war and had long opposed abolitionism and the free black population, regarding them as competition for jobs and blaming them for driving down wages. Alleging that the war was merely an upper class abolitionist war to free slaves who might move north and compete for jobs and housing, the poorer classes did not welcome a draft, especially one from which a richer man could buy an exemption. The poor formed clubs that would buy exemptions for their unlucky members. As a result of the Enrollment Act, rioting began in several Northern cities, the most heavily hit being New York City. A mob reported as consisting principally of Irish immigrants rioted in the summer of 1863, with the worst violence occurring in July during the Battle of Gettysburg. The mob set fire to everything from African American churches and an orphanage for "colored children" as well as the homes of certain prominent Protestant abolitionists. A mob was reportedly repulsed from the offices of the staunchly pro-Union New York Tribune by workers wielding and firing two Gatling guns. The principal victims of the rioting were African Americans and activists in the anti-slavery movement. Not until victory was achieved at Gettysburg could the Union Army be sent in; some units had to open fire to quell the violence and stop the rioters. By the time the rioting was over, perhaps up to 1,000 people had been killed or wounded. There were a few small scale draft riots in rural areas of the Midwest and in the coal regions of Pennsylvania.
While restoration of the Union was the main goal for which they fought, they became convinced that this goal was unattainable without striking against slavery.
About 180,000 black soldiers and an estimated 10,000 black sailors fought in the Union Army and Navy, all of them in late 1862 or later, except for some blacks who enrolled in the Navy earlier.
[V]ery few blacks serve in the Confederate armed forces, as compared to hundreds of thousands who serve for the Union.
Forty thousand Canadians alone, some of them black, came south to volunteer for the Union cause.
Rioters were mostly Irish Catholic immigrants and their children. They mainly attacked the members of New York's small black population. For a year, Democratic leaders had been telling their Irish-American constituents that the wicked 'Black Republicans' were waging the war to free the slaves who would come north and take away the jobs of Irish workers. The use of black stevedores as scabs in a recent strike by Irish dockworkers made this charge seem plausible. The prospect of being drafted to fight to free the slaves made the Irish even more receptive to demogogic rhetoric.
The American Civil War was a civil war in the United States from 1861 to 1865, fought between the northern United States and the southern United States. The civil war began primarily as a result of the long-standing controversy over the enslavement of black people. War broke out in April 1861 when secessionist forces attacked Fort Sumter in South Carolina shortly after Abraham Lincoln had been inaugurated as the President of the United States. The loyalists of the Union in the North, which also included some geographically western and southern states, proclaimed support for the Constitution. They faced secessionists of the Confederate States in the South, who advocated for states' rights in order to uphold slavery.
The Confederate States Army was the military land force of the Confederate States of America during the American Civil War (1861–1865), fighting against the United States forces. On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the newly chosen Confederate president, Jefferson Davis. Davis was a graduate of the U.S. Military Academy, and colonel of a volunteer regiment during the Mexican–American War. He had also been a United States Senator from Mississippi and U.S. Secretary of War under President Franklin Pierce. On March 1, 1861, on behalf of the Confederate government, Davis assumed control of the military situation at Charleston, South Carolina, where South Carolina state militia besieged Fort Sumter in Charleston harbor, held by a small U.S. Army garrison. By March 1861, the Provisional Confederate Congress expanded the provisional forces and established a more permanent Confederate States Army.
The United States Colored Troops (USCT) were regiments in the United States Army composed primarily of African-American (colored) soldiers, although members of other minority groups also served with the units. They were first recruited during the American Civil War, and by the end of that war in April 1865, the 175 USCT regiments constituted about one-tenth of the manpower of the Union Army. About 20% of USCT soldiers died, a rate about 35% higher than that for white Union troops. Despite heavy casualties, many fought with distinction, 15 USCT soldiers receiving the Medal of Honor and numerous others receiving other honors.
In the context of the American Civil War (1861–65), the border states were slave states that did not declare a secession from the Union and did not join the Confederacy. To their north they bordered free states of the Union and to their south they bordered Confederate slave states. Of the 34 U.S. states in 1861, nineteen were free states and fifteen were slave states. Two slave states never declared a secession or adopted an ordinance: Delaware and Maryland. Four others did not declare secession until after the Battle of Fort Sumter and were briefly considered to be border states: Arkansas, North Carolina, Tennessee and Virginia—after this, they were less frequently called "border states". Also included as a border state during the war is West Virginia, which was formed from 50 counties of Virginia and became a new state in the Union in 1863.
During the American Civil War (1861–1865), the Union, also known as the North, referred to the United States of America, specifically to the national government of President Abraham Lincoln and the 20 free states and 5 border states that supported it. The Union was dedicated to the defeat and termination of the Confederate States of America, informally called "the Confederacy" or "the South".
The American Civil War saw cavalry tactics move largely away from the offensive towards the defensive, with the emphasis on screening, reconnaissance, raiding and harassment. Development of the rifled musket had also rendered the cavalry charge impractical.
The 1st Regiment, Ohio Volunteer Infantry was an infantry regiment in the Union Army during the American Civil War. It served in the Western Theater in a number of campaigns and battles.
During the American Civil War, the State of Ohio played a key role in providing troops, military officers, and supplies to the Union army. Due to its central location in the Northern United States and burgeoning population, Ohio was both politically and logistically important to the war effort. Despite the state's boasting a number of very powerful Republican politicians, it was divided politically. Portions of Southern Ohio followed the Peace Democrats and openly opposed President Abraham Lincoln's policies. Ohio played an important part in the Underground Railroad prior to the war, and remained a haven for escaped and runaway slaves during the war years.
The Southern bread riots were events of civil unrest in the Confederacy during the American Civil War, perpetrated mostly by women in March and April 1863. During these riots, which occurred in cities throughout the South, women and men violently invaded and looted various shops and stores.
The Commonwealth of Massachusetts played a significant role in national events prior to and during the American Civil War (1861-1865). Massachusetts dominated the early antislavery movement during the 1830s, motivating activists across the nation. This, in turn, increased sectionalism in the North and South, one of the factors that led to the war. Politicians from Massachusetts, echoing the views of social activists, further increased national tensions. The state was dominated by the Republican Party and was also home to many Radical Republican leaders who promoted harsh treatment of slave owners and, later, the former civilian leaders of the Confederate States of America and the military officers in the Confederate States Army.
During the American Civil War, North Carolina joined the Confederacy with some reluctance, mainly because neighboring Virginia had done so, and it remained a divided state throughout the war, with much of the population of the Appalachian Mountains in the western part of the state retaining Union sentiment. Even so, North Carolina contributed more troops to the Confederacy than any other state, and channeled many vital supplies through the major port of Wilmington, in defiance of the Union blockade.
The Colorado Territory was formally created in 1861 shortly before the bombardment of Fort Sumter sparked the American Civil War. Although sentiments were somewhat divided in the early days of the war, Colorado was only marginally a pro-Union territory. Colorado was strategically important to both the Union and Confederacy because of the gold and silver mines there as both sides wanted to use the mineral wealth to help finance the war. The New Mexico Campaign was a military operation conducted by Confederate Brigadier General Henry Sibley to gain control of the Southwest, including the gold fields of Colorado, the mineral-rich territory of Nevada and the ports of California. The campaign was intended as a prelude to an invasion of the Colorado Territory and an attempt to cut the supply lines between California and the rest of the Union. However, the Confederates were defeated at the Battle of Glorieta Pass in New Mexico and were forced to retreat back to Texas, effectively ending the New Mexico Campaign.
New York City during the American Civil War (1861–1865) was a bustling American city that provided a major source of troops, supplies, equipment and financing for the Union Army. Powerful New York politicians and newspaper editors helped shape public opinion toward the war effort and the policies of President Abraham Lincoln. The port of New York, a major entry point for immigrants, served as recruiting grounds for the Army. Irish and Germans participated in the war at a high rate.
The 1st Arkansas Infantry (1861–1865) was a Confederate Army infantry regiment during the American Civil War. The regiment was raised in April 1861 by Colonel Thompson B. Flournoy. It moved first to Virginia, but transferred back to Tennessee and served the rest of the war in the western theater, seeing action in the Kentucky, Tennessee and Georgia campaigns. Following its depletion in numbers, the regiment was consolidated several times with other Arkansas regiments, finally merging in 1865 into the 1st Arkansas Consolidated Infantry Regiment. There were three regiments known as "1st Arkansas" during the war. The second unit with the designation of "1st Arkansas" was the 1st Infantry, Arkansas State Troops, which was mustered into Confederate service at Pitman's Ferry, Arkansas, on 23 July 1861, under the command of Colonel Patrick Cleburne; this unit was eventually redesignated as the 15th Arkansas Volunteer Infantry. The third unit bearing the title "1st Arkansas" was the 1st Arkansas Volunteer Infantry, which served with the Union Army.
A large contingent of African Americans served in the American Civil War. 186,097 black men joined the Union Army: 7,122 officers, and 178,975 enlisted soldiers. Approximately 20,000 black sailors served in the Union Navy and formed a large percentage of many ships' crews. Later in the War, many regiments were recruited and organized as the United States Colored Troops, which reinforced the Northern side substantially in the last two years. Both Northern free blacks and Southern runaway slaves joined the fight. Throughout the course of the war, black soldiers served in forty major battles and hundreds of more minor skirmishes; sixteen African Americans received the Medal of Honor.
The general officers of the Confederate States Army (CSA) were the senior military leaders of the Confederacy during the American Civil War of 1861–1865. They were often former officers from the United States Army prior to the Civil War, while others were given the rank based on merit or when necessity demanded. Most Confederate generals needed confirmation from the Confederate Congress, much like prospective generals in the modern U.S. armed forces.
The Military forces of the Confederate States, also known as Confederate forces, were the military services responsible for the defense of the Confederate States during its brief existence (1861-1865).
The state of medical knowledge at the time of the Civil War was extremely primitive. Doctors did not understand infection, and did little to prevent it. It was a time before antiseptics, and a time when there was no attempt to maintain sterility during surgery. No antibiotics were available, and minor wounds could easily become infected, and hence fatal. While the typical soldier was at very high risk of being shot and killed in combat, he faced an even greater risk of dying from disease.
Irish-American Catholics served on both sides of the American Civil War (1861–1865) as officers, volunteers and draftees. Immigration due to the Irish Great Famine (1845–1852) had provided many thousands of men as potential recruits although issues of race, religion, pacifism and personal allegiance created some resistance to service. A significant body of these Irishmen later used the military experience gained in the American Civil War to fight against British forces with the goal of establishing an Irish Republic as members of the Irish Republican Brotherhood, the Fenian Brotherhood and Clan na Gael. In addition very large numbers of Scots-Irish Protestants were involved in the American Civil War, especially the Confederacy.
The 61st New York Volunteer Infantry Regiment, also known as the "Astor Regiment", was an infantry regiment of the Union Army during the American Civil War.
