A casualty is someone injured, killed, captured, or missing in a military engagement. The Civil War had plenty of all these. The casualty totals in the Civil War can only be treated as estimates. The exact numbers cannot be exactly known.

Dead at Spotsylvania, 1864.

Due to exhaustive research by many credible and earnest Civil War scholars, the casualty numbers presented here can be considered to be as accurate as possible. I have relied on trustworthy sources for the numbers and statistics I share in this post. The exact number of Civil War casualties will forever be a topic for debate.

One fact we can be certain of regarding Civil War casualty counts, the carnage of the Civil War was immense. War and disease provided the Grim Reaper with all he desired.

Let us not neglect to know that the cold numbers and statistics shown in this post are facts that represent real people. People who fought in a vicious war, who bled red blood whether they were clothed in blue or gray. People who lost limbs or were severely disfigured, people who died miserable, slow deaths of disease or injury, people who perished instantaneously in groups during battle, or slowly had life ebb away as they sprawled alone and incapacitated in the aftermath of a major battle or minor skirmish. Many died agonizing and feverish deaths of disease. These numbers are human beings.

How Many Died in the Civil War? The quick and simple answer is that no one knows for sure exactly how many died in the Civil War, neither for the North or the South. An estimate of the deaths in the Civil War is 623,026. This means that of men of service age, one out of eleven men died during the Civil War years between 1861 and 1865.

Below is a chart showing how the Civil War compares in total deaths to other wars:

How Many Casualties in the Civil War? For both sides in the Civil War, 471,427 can be considered as a minimum number of those wounded. When added to the estimate of 623,026 deaths, the total estimate of Civil War casualties is 1,094,453.

DEATHS IN CONFEDERATE ARMIES
James B. Fry, United States Provost Marshal-General, provides a report in 1865-1866 that includes a tabulation of Confederate losses. Fry’s report is compiled from the muster-rolls which are on file in the Bureau of Confederate Archives. This report is incomplete, as Confederate records can be, and often are, spotty. For example, in these records the Alabama rolls are mostly missing. Nonetheless, the numbers are worth noting. From General Fry’s report, the following table was created by William E. Fox in his Regimental Losses in the American Civil War, 1861-1865:

During the Civil War, soldiers would speak about "Seeing the elephant." The "elephant" was battle, combat, being under enemy fire.

Both the Confederacy and the Union had armies made up mostly of volunteers, with much fewer soldiers actually belonging to the Regular Army. Whether volunteer or Regular Army, the vast majority of these young men had never faced enemy fire. Many were away from home for the first time in their young lives. They had lived quietly and peacefully in small towns, farms, or cities. Now, they were learning to kill, and facing the great possibility of being killed. As these men trained and marched, preparing for battle, the thought of "Seeing the elephant" for the first time weighed on their minds.

“Bang, bang, bang, a rattle, de bang, bang, bang, a boom, de bang…whirr-siz-siz-siz–a ripping, roaring, boom, bang!” – Confederate Sam R. Watkins describing a "fire fight." Sam Watkins was twenty-one years old and from Columbia, Tennessee when he joined up to fight in the Civil War. He kept a journal and recorded his experiences and thoughts during the war. His words give us great insight into the Civil War.   “It was eyes right, guide center! Close-up, guide right, halt, forward, right oblique, left oblique, halt, forward, guide center, eyes right, dress up promptly in the rear, steady, double quick, charge bayonets, fire at will, is about all that a private soldier knows of a battle.” – Confederate Sam R. Watkins.

I was a ploughboy in the field,
A gawky, lazy, dodger,
When came the conscript officer
And took me for a sodger.
He put a musket in my hand,
And showed me how to fire it;
I marched and counter-marched all day;
Lord, how I did admire it!
– This tune is "The Valiant Conscript" and it is sung to the music of "Yankee Doodle."

“Our men are not sufficiently impressed with a sense of honor that it is better to die by fire than to run.”
– General William Hardee of the Confederacy.

“War is at best barbarism…Its glory is all moonshine. It is only those who have neither fired a shot, nor heard the shrieks and groans of the wounded who cry aloud for blood, more vengeance, more desolation. War is hell.”
– William Tecumseh Sherman. These words are from his June 19, 1879 address to the Michigan Military Academy.

“We made a bargain with them that we would not fire on them if they would not fire on us, and they were as good as their word. It seems too bad that we have to fight men that we like.”
– Words of a Union soldier.

Perhaps some of you reading the LearnCivilWarHistory.com blog are veterans or soldiers who know full well what it is like to under fire. However, for most us, we can only wonder and imagine what it is like to be "Seeing the elephant," just as the young men of the Civil War wondered and imagined so many years ago.

Below are the experiences of being under Civil War fire as described by Captain Frank Holsinger. Try to imagine yourself in Captain Frank Holsinger’s shoes (or rather, brogans) as you read this stirring account of what it was like to be "Seeing the elephant” in the Civil War:

Excerpts from: How Does One Feel Under Fire?
by Captain Frank Holsinger, 19th United States Colored Infantry.

Barnes&Noble: Ambrose Bierce: Civil War Stories Ambrose Bierce: Civil War Stories

"When the nerves are thus unstrung, I have known relief by a silly remark. Thus at Antietam, when in line of battle in front of the wood and exposed to a galling fire from the cornfield, standing waiting expectant with “What next?” the minies zipping by occasionally, one making the awful thud as it struck some unfortunate. As we thus stood listlessly, breathing a silent prayer, our hearts having ceased to pulsate or our minds on home and loved ones, expecting soon to be mangled or perhaps killed, some one makes an idiotic remark; thus at this time it is Mangle, in a high nasal twang, with “D—–d sharp skirmishing in front.” There is a laugh, it is infectious, and we are once more called back to life.

At the completion of Captain Frank Holsinger’s military service, he was given a brevet rank of major. Holsinger settled in Kansas.

Walt Whitman’s brother George Washington Whitman, fought for the Union during the Civil War and was injured at Fredericksburg in 1862. Walt went to Virginia in search of his hospitalized brother and was relieved to discover that George’s wounds were not serious. The wounded, the conditions, and the plentiful misery of a Civil War hospital, led Walt Whitman to volunteer at age forty-two to be a nursing aid, he served for over three years in this capacity.

Whitman wrote two volumes of poetry about the Civil War: Drum Taps (1865) and Sequel to Drum Taps (1866), after witnessing first-hand the suffering, bravery, wastefulness, heroism, and tragedy of war while working in hospitals during the Civil War.

Barnes&Noble: Walt Whitman’s Civil War

Observations of poet Walt Whitman, in 1865: ’’Unnamed, unknown, remain and still remain the bravest soldiers. Our manliest, our boys, our hardy darlings: no picture gives them. Likely, the typical one of them (standing, no doubt, for hundreds, thousands) crawls aside to some bush-clump or ferny tuft on receiving his death-shot; there, sheltering a little while, soaking roots, grass, and soil with red blood; the battle advances, retreats, flits from the scene, sweeps by; and there, haply with pain and suffering…the last lethargy winds like a serpent round him; the eyes glaze in death;…and there, at last the Bravest Soldier, crumbles in Mother Earth, unburied and unknown.’’ Walt Whitman is famous for two poem elegies he wrote about President Abraham Lincoln after Lincoln was assassinated, these poems are: ’’O Captain! My Captain!’’ and ’’When Lilacs Last in Dooryard Bloom’d.’’ Not even the most casual student of the Civil War should ignore these two Walt Whitman poems. Below you will find the first of these two poems.

O Captain! My Captain!

by Walt Whitman

My Captain does not answer, his lips are pale and still;

My father does not feel my arm, he has no pulse nor will;

The ship is anchor’d safe and sound, its voyage closed and done;

From fearful trip the victor ship comes in with object won!

Exult, O shores, and ring, O bells!

But I with mournful tread,

Walk the deck my Captain lies,

Fallen cold and dead.

Stonewall Jackson, shot by friendly fire the night of May 2, has his mangled left arm amputated early in the morning of May 3 at a field hospital. General Robert E. Lee says of Jackson’s importance to him and the Army of Northern Virginia; "He has lost his left arm, but I have lost my right. Any victory would be dear at such a cost."

The best artillery officer of the Confederacy, Colonel Edward Porter Alexander, reports to General James Ewell Brown "Jeb" Stuart early the morning of May 3 that a high piece of ground called Hazel Grove would be the perfect point to stage an artillery attack. Stuart sends a brigade made up of Tennessee and Alabama regiments to Hazel Grove. At dawn, the Confederates attack, just in time to capture four cannon and one hundred men of a Union rear guard.

Because of its very advantageous position for artillery, Hazel Grove is the key to the battlefield. If "Fighting Joe" Hooker controls Hazel Grove, he could keep the two wings of the Army of Northern Virginia separated. Hooker, with his superior number of troops, could then destroy Lee’s parted army.

Despite the great advantage of holding Hazel Grove, Hooker decides to abandon the position. Hooker chooses instead to have his troops fall back from Hazel Grove to an elevated clearing called Fairview.

Barnes&Noble: Lee’s Lieutenants: A Study in Command by Douglas Freeman, Abridged by Stephen W. Sears

Colonel Alexander quickly moves about 36 cannon into the open space of Hazel Grove and begins firing at Yankee artillery located about 1200 yards away at Fairview, and at the crossroads of Chancellorsville itself. The Confederate artillery is triumphant. It was recently reorganized into a battalion system, allowing it to have an ample amount of guns in large, mobile groups. This organization of the Confederate artillery made it much more efficient and effective. The advantageous high ground of Hazel Grove and the battalion system of artillery management led Douglas Southall Freeman (the Army of Northern Virginia’s leading historian) to comment; "At Hazel Grove the finest artillerists of the Army of Northern Virginia were having their greatest day." With the artillery support, the Confederate infantry stages a full attack on the Federal lines.

General "Fighting Joe" Hooker experiences personally some of the Confederate artillery. Hooker is at his Chancellorsville house headquarters leaning against a white porch column on the second-story veranda. A Confederate shell hits the porch column but does not explode. Hooker is knocked unconscious and suffers a concussion, but the dazed and groggy "Fighting Joe" continues in command.

Some of Hooker’s officers wish Hooker would start a counterattack in response to the Confederate offensive. These officers are disappointed when Hooker instead chooses to retreat one or two miles towards the north into a defensive line.

The two wings of Lee’s army reunite and Lee’s great gamble at Chancellorsville pays off. The Confederates push the Yankees back to the Chancellorsville crossroads intersection. General Lee rides his horse Traveller onto the battle scene, the sight of Lee with Traveller charges the enthusiasm of the Confederates and they cheer their general. Lee is in triumph and his men are celebrating, but a crisis soon comes.

Word comes from Fredericksburg that Lee’s rear guard is in trouble. General Jubal Early leads the rear guard and his 11,000 men are up against twice as many Union soldiers led by General John Sedgwick. On the morning of May 3, Confederate Colonel Thomas M. Griffen accepts (against regulations) a flag of truce. During the truce, the Federals see that they outnumber their enemy. The Federals advance upon the Confederates, moving over ground where so much loss and grief had occurred for them the previous December during the Battle of Fredericksburg. They cross the plain below Marye’s Heights, and move over the stone wall and Sunken Road, giving Sedgwick’s troops a path to the rear of General Lee’s position.

Sedgwick’s advance ends at Salem Church, about four miles west of Marye’s Heights. Five brigades of Alabama troops (all tough and veteran fighters) led by Marcellus Wilcox, use Salem Church for protection as they make a stand. Lee sends General Lafayette McLaws and his troops to Salem Church for reinforcement of Wilcox and his Alabamians. Later, Lee himself arrives. The fighting tapers off late in the day on May 3. On May 4, the Confederates push Sedgwick back to the Rappahannock River. The Union soldiers retreat across the Rappahannock on the night of May 4-5.

With Sedgwick now across the Rappahannock River, Lee returns to Chancellorsville on May 5 and begins planning a new offensive against Hooker’s men. Nevertheless, a new Confederate offensive proves unnecessary. On the morning of May 6, Lee learns from scouts that under the cover of night, the Yankees have retreated north of the Rappahannock River.

Barnes&Noble: Chancellorsville

President Lincoln has been monitoring the Chancellorsville battle from the telegraph office in the War Department. During the battle, Lincoln hears reports that are often contradictory or incomplete. On May 6 however, Lincoln learns the certain results of Chancellorsville. He is not pleased. A newspaperman wrote Lincoln’s face turned "ashen" upon hearing the bad news of Chancellorsville. The president exclaims, "My God! My God! What will the country say?" The country’s reaction to the Union defeat at Chancellorsville is not good. With the Union’s defeat at Fredericksburg, and now a loss at Chancellorsville, the country has been hearing too much bad news too often. Things are looking bad for the Union.

For General Robert E. Lee and the Confederacy, things are looking good. Lee has won a great battle at Chancellorsville, it his masterpiece.

Meanwhile, twenty-five miles southeast of Chancellorsville in a house at Guinea Station, General Thomas Jonathan "Stonewall" Jackson is healing from his wounds and amputation. The news from there is good too for General Lee and the South, as Stonewall seemed to be recovering…

The night of May 1, Generals Robert E. Lee and Thomas Jonathan "Stonewall" Jackson are sitting on Union hardtack boxes by campfire. Lee and Jackson are working on their battle plans. Outnumbered more than two to one, Lee still wants to take the offensive against Hooker. Lee knows the Federals hold a good defensive position on the high ground around Chancellorsville and the situation is too risky for a direct attack. Moreover, the Rappahannock River protects the Federal left, so turning it is impossible. Lee needs a way to go on the offensive. General Jeb Stuart soon provides the way.

Stuart’s cavalry scouts have found that Hooker’s right flank has no natural or artificial obstacle to protect it, Hooker’s right flank is "in the air" and vulnerable. To move without detection around to the Federal right flank, Lee and Jackson need a route through the Wilderness. One of Stonewall Jackson’s staff officers finds a man who lives in the area, and this local knows of a road used to haul charcoal to an iron-smelting furnace. Jackson can move his troops to the Federal right flank by using the charcoal-hauling road and a few other roads.

At Chancellorsville, Robert E. Lee gambles with his battle plans. Lee stays with only 15,000 men to face Hooker’s main force, while Jackson takes his corps of about 30,000 men through a way of roads and paths to the Federal right. Stuart’s cavalry will screen Jackson’s movement from the Federals and Lee will divert Hooker’s attention as Jackson’s men make their way. Meanwhile, General Jubal Early has his men at Fredericksburg. Splitting the Army of Northern Virginia into three separate groups is a big risk. If Hooker chooses to take the offensive, his superior number of troops can destroy any of Lee’s separated groups. Lee counts on "Fighting Joe" Hooker to do nothing while Stonewall Jackson makes his march to the Federal right flank.

Early the morning of May 2, Stonewall Jackson begins his march. As Lee remains behind with his relatively meager amount of troops, Jackson takes his 30,000 men on a twelve-mile march around Hooker’s army. Jackson has Stuart’s cavalry to screen his march, but Union infantry still detects the Rebel movements and troops under General Dan Sickles attack the tail of Jackson’s column. General "Fighting Joe" Hooker knows of Stonewall Jackson’s flanking movement, but Hooker thinks the Rebels are retreating instead of making offensive movements. Hooker does nothing to prepare for an attack on his right flank. By late in the afternoon of May 2, Stonewall has 30,000 men behind the unaware Federal troops.

Stonewall Jackson tells Major Eugene Blackford, "You can go forward then," and with their bone-chilling Rebel Yell battle cry, the Confederates advance out of the cover of the Wilderness. The 11th Corps, under command of General Oliver O. Howard, have the Federal right. Mostly made up of German-Americans, the 11th Corps is about 12,000 strong. The 11th Corps, known as the "Dutch Corps" (a mangling of the word "Deutsche" for "German"), has a poor reputation based on previous battle action. Today would not improve the "Dutch Corps" reputation. The Confederate attack took place near suppertime and most of Howard’s troops are preparing food or relaxing. The oncoming wall of attacking rebels surprises the Federals. By nightfall, Jackson’s men have backed the Federals up two miles. It was a moonlit night, and even after dark some fighting continues in the woods and thickets of the Wilderness. Night fighting was very rare in the Civil War, but this is an example of it. Finally, darkness ends the Confederate attack.

General Thomas Jonathan "Stonewall" Jackson and several other officers are looking for a way to renew the attack. They are out ahead of their lines in the darkness and confusion of the Wilderness, scouting for the best way to begin a new attack. As they are returning to their lines at a trot, they come upon a regiment from North Carolina. In the dark, the Tarheels hear the horses approaching and mistake their riders as Federals, the North Carolinians begin firing and Stonewall Jackson is shot. One bullet hits Jackson in his right hand, a second in his left wrist, and the third strikes him in his left arm between the shoulder and elbow. Stonewall’s frightened horse bolts and runs toward the Federal lines, bashing Jackson’s face into a low tree branch before Jackson regains control of the horse. The most damaging third bullet shatters bone and cuts an artery. Stonewall Jackson is severely injured. He is in great pain and moved to the rear on a stretcher, but not before urging his men to continue the fight and finish the victory. General Jeb Stuart assumes command of General Jackson’s 11th Corps.
