CHAPTER XVIII.
BATTLE OF SHARPSBURG, OR ANTIETAM.
Bloodiest Single Day of the War—Comparison of Casualties—Hooker opens the Fight against Jackson’s Centre—Many Officers among the Fallen early in the Day—McLaws and Walker in time to meet Sumner’s Advance under Sedgwick—Around Dunker Chapel—Richardson’s splendid Advance against the Confederate Centre the Signal of the bursting of another Storm—Longstreet’s and D. H. Hill’s Troops stood before it—Fall of General G. B. Anderson—General Richardson mortally wounded—Aggressive Spirit of his Command broken—Wonderful Cannon-shot—General D. H. Hill’s Third Horse killed under him.
The field that I have described—the field lying along the Antietam and including in its scope the little town of Sharpsburg—was destined to pass into history as the scene of the bloodiest single day of fighting of the war, and that 17th of September was to become memorable as the day of greatest carnage in the campaigns between the North and South.
Gettysburg was the greatest battle of the war, but it was for three days, and its total of casualties on either side, terrible as it was, should be one-third larger to make the average per diem equal to the losses at Sharpsburg. Viewed by the measure of losses, Antietam was the fourth battle of the war, Spottsylvania and the Wilderness, as well as Gettysburg, exceeding it in number of killed and wounded, but each of these dragged its tragedy through several days.
Taking Confederate losses in killed and wounded as the criterion of magnitude in battles, the Seven Days’ Battle (following McClellan’s retreat), Gettysburg, and Chickamauga exceeded Sharpsburg, but each of these occupied several days, and on no single day in any one of them was there such carnage as in this fierce struggle.
The Confederates lost in killed and wounded in the Seven Days’ Battle 19,739,—more, it will be observed, than at Gettysburg (15,298), though the total loss, including 5150 captured or missing, at the latter, brought the figures up to those of the former (20,614), in which the captured or missing were only 875. Our killed and wounded at Chickamauga were 16,986, but that was in two days’ battle, while at Chancellorsville in three days the killed and wounded were 10,746. It is impossible to make the comparison with absolute exactness for the Confederate side, for the reason that our losses are given for the entire campaign in Maryland, instead of separately for the single great battle and several minor engagements. Thus computed they were 12,187.[64] But nearly all of these are known to have been losses at Sharpsburg, and, making proper deductions for the casualties in other actions of the campaign, the Confederate loss in this single day’s fighting was still in excess of that at the three days’ fight at Chancellorsville (10,746), and for the single day far larger proportionally than in the two days at Chickamauga, three days at Gettysburg, or seven days on the bloody Chickahominy.
But the sanguinary character of this battle is most strikingly exhibited by a comparison of the accurate figures of the Federal losses, returned specifically for the day. These show a total killed and wounded of 11,657 (or, including the captured and missing, 12,410), as contrasted with 17,567 killed and wounded in three days at Gettysburg, 16,141 in eight days at Spottsylvania, and 14,283 in the three days at the Wilderness, while the three and two days’ fighting respectively at Chancellorsville and Chickamauga were actually productive of less loss than this battle of one day. The exceeding losses of this battle are further shown by the fact that of the 11,657 Federals stricken on the field, the great number of 2108 were actually slain,—more than two-thirds of the number killed in three days at Gettysburg (3070). And this tremendous tumult of carnage was entirely compassed in the brief hours from dawn to four o’clock in the afternoon.
At three o’clock in the morning of the 17th firing along the picket lines of the confronting and expectant armies became quite frequent, and before daylight the batteries began to plough the fields in front of them, feeling, as it were, for the ranks of men whose destruction was better suited to their ugly purpose.
As the dawn came, the fire spread along both lines from left to right, across the Antietam and back again, and the thunder of the big guns became continuous and increased to mighty volume. To this was presently added the sharper rattling of musketry, and the surge of mingling sound sweeping up and down the field was multiplied and confused by the reverberations from the rocks and hills. And in this great tumult of sound, which shook the air and seemed to shatter the cliffs and ledges above the Antietam, bodies of the facing foes were pushed forward to closer work, and soon added the clash of steel to the thunderous crash of cannon-shots.
