THE MARYLAND CAMPAIGN.
I.
SOUTH MOUNTAIN.
197
Lying in camp near Arlington, the
Bucktails, with the other regiments constituting the Pennsylvania Reserves, appreciated
deeply the rest vouchsafed to them. The men who had taken part in the Shenandoah Valley
campaign exchanged experiences with those who had lived through the terrible
experiences of the Seven Days' Retreat, and this relation of occurrences, combined
with the execution of camp duties, completely filled the all too short September days.
In the meantime, General McClellan
labored to restore order and effectiveness to the troops under his command.[1]
The army was reorganized, corps reconstituted, and discipline more firmly established.
Though much of this work was done while marching to meet the enemy, between. the 7th and
13th, much was accomplished while still in the vicinity of Washington. The camp was but a
short distance from the capital, yet permissions to visit the city were almost without
exception refused.
198
The elite
of Washington, in handsome equipages, carne driving about the camps in the cool
afternoons, returning to spend their evenings amidst various divertisements ; but the
soldiers, only partially recovered from their arduous services, remained in camp, being
whipped into shape for another campaign by their officers, who were glad to be again under
the orders of "Little Mac."[2]
As by the 3rd or 4th it was apparent
that Lee had withdrawn his forces from the immediate vicinity of Washington, it became
of vital importance to ascertain his future intentions. Gradually his plans became plain.
He intended to invade Maryland and' perhaps Pennsylvania. His object was twofold. First,
by crossing the Potomac into Maryland and advancing along its northern side, he would be
threatening both Washington and Baltimore in his rear; he would be approaching the
Cumberland Valley, which gives access to Pennsylvania; and he would also be able to
re-establish communications with Richmond via the Shenandoah Valley. Second, the
Southerners believed that Maryland was, so to speak, groaning under the Northern yoke; and
that nothing but lack of opportunity prevented thousands of the inhabitants of that
State from enlisting under the banners of the Confederacy. This opportunity the invasion
would afford.
Lee moved his troops on the Virginia
side of the river towards Leesburg, some thirty miles northwest from Washington.
Arriving at this place, he then crossed his army over the Potomac and advanced on
Frederick City almost due north. The passage of the river was made between the 4th and
7th, and on the 8th the Confederate General issued a proclamation "To the People of
Maryland" inviting them to assist his army
199
in regaining
for them the rights of which they had been despoiled.[3]
With Lee's invasion of soil regarded
as Northern, his designs had become obvious to McClellan, who put his army in motion.
The Union forces advanced, leisurely, towards Frederick by five parallel roads; the
columns being so disposed as to cover both Washington and Baltimore.[4]
The general direction of the Potomac River from about two miles south of the southern
boundary of Pennsylvania (some twenty-five miles west of Chambersburg) to Washington is
from the northwest to the southeast. Fifty miles northwest of Washington the Potomac is
increased by the waters of the Shenandoah River, which, flowing north, empty into it at a
place called Harpe0s Ferry. Harper's Ferry itself is situated in the crotch of the two
rivers, being west of the Shenandoah and south of the Potomac. The Blue Ridge, which forms
the eastern boundary of the Shenandoah Valley, running north close to the eastern bank
of the Shenandoah, continues to the southern bank of the Potomac, where it is known as
Loudon Heights. A continuation of the ridge, commencing at the north side of the river, is
known as the South Mountain. A short distance to the west of the South Mountain,
commencing at the north bank of the Potomac, is a ridge named Maryland Heights.
Harper's Ferry was held by a small
Union force[5]
under General Miles, and Lee expected that upon his arrival at Frederick it would be
evacuated. In fact, to insure the safety of the Confederate army, if it was not evacuated
it would have to be reduced. This necessity becomes apparent should we,
200
ignoring
minor facts, consider the Cumberland Valley merely as a natural continuation of the
Shenandoah Valley, the line of division being the Potomac River. For, if Harper's Ferry in
the Shenandoah Valley was held by the Union troops, while Lee proceeded north into the
Cumberland Valley, they would be in his rear, able both to cut his communications and also
to assume the offensive when strengthened. Lee, finding by the 9th that the Union troops
did not intend to abandon their position,[6] issued an order on that date[7]
separating his command in order to compass its fall. Jackson was to march to Martinsburg
to capture the small Union force stationed at that point, or to drive it south to the
Ferry; McLaws was to take possession of the Maryland Heights; and Walker was to seize
the Loudon Heights. The various movements were to be executed by the 12th, then the
reduction of the garrison was to follow, after which the commands were to rejoin the main
body. Hill was to remain at the western side of South Mountain, and a cavalry force under
Stuart at the eastern side, to observe and retard the Union advance.
The rate of advance of the Union army
in the meantime had been noted, and Lee was confident that his army would have ample time
to execute his orders before McClellan would be in a position to succor the endangered
garrison.
McClellan, on his part, was unwilling
to advance rapidly until he received more definite information as to his opponent's
designs. The Bucktails, late on the 6th, had marched into Washington over the Long Bridge,
some of the men there
201
receiving
much needed clothing.[8]
On the 7th they arrived at Leesboro; on the 9th they moved forward to Brookville; on the
loth they advanced four miles further; and on the iith they reached Lisbon on the
Frederick pike. While at this place General Reynolds left the division. Governor Curtin,
alive to the peril of the impending invasion of his State, issued a proclamation by
authority of the President, calling into immediate service 50,000 of the militia of the
State, and General Reynolds on the 12th, by order of the Secretary of War, proceeded to
Harrisburg to organize and command these forces.
A reorganization of the division of
Pennsylvania Reserves became necessary, and was accomplished as follows

The First army corps was commanded by
General Hooker and with the Ninth army corps, commanded by General Reno, formed the right
wing of the Army of the Potomac, General Burnside having command of the two corps.
On the 13th the Bucktails were again
in motion. They crossed the Monocacy, three miles below Frederick, bivouacking for the
night near that stream. On the same evening,[10] General McClellan was
favored by fortune. A copy of General Lee's order of the 9th, making the dispositions
above summarized for the reduction of Harper's Ferry, fell into his hands. The Union army
was not more than twenty miles[11] from the passes of the South
Mountain, beyond which the enemy was separated, while Franklin's corps was not more than
twelve miles from Crampton's Gap. McClellan, in an order dated 6.20 P. m, ordered Franklin
to move next morning.[12]
Burnside's command was to move "this evening and early "to-morrow morning."
Warned, however, by Stuart of McClellan's approach, Lee commenced early on the t4th to
strengthen
203
the defences
of the mountain passes through which the Federals must force their way, their right
headed for Crampton's Gap, and their left for Turner's Gap.
The Bucktails left camp on the
morning of the 14th. Seven miles from Frederick the regiment passed Middletown, and in a
nearby field made coffee and ate dinner. The South Mountain is plainly visible from this
point, rising some one thousand feet in the air, its base protected by a series of ridges.
Six miles north of Crampton's Gap, which Franklin carried in the afternoon after a rather
small though spirited action, is Turner's Gap, the pass through which Burnside was to
drive his force. The pike from Middletown to Hagerstown runs through the Gap, which is
formed by a depression of about four hundred feet. The mountain on the north side of the
pike is divided into two crests by a narrow valley, which runs at right angles to the
road, the crest of the mountain thus being formed of two ridges. The Gap itself is
unassailable; but by roads running parallel to and into the main road its evacuation ,can
be forced.
General Burnside had under his
command the Ninth corps under General Reno, and the First corps under General Hooker. At 6
A. m., the advance of the Ninth corps moved to assault the left, or south side, of the
pass. By brisk fighting they reached the crest at 9 A. M., and succeeded in establishing
their position despite the efforts of the Confederates. To open the Gap, it now became
necessary to take the right, or north side, of the turnpike. Reno's men were to move north
from the ground they had won in the morning, and Hooker's corps were to advance in a sort
of semi-circular movement and close in on the pike at the summit. To do this the
Pennsylvania Reserves, forming the extreme right of Hooker's corps, would have to be
thrown forward till Seymour's brigade
204
reached the
second ridge. Then while Seymour swept down the second ridge, Magilton's and Gallagher's
brigades would advance down the ravine.
The Bucktails in accordance with
their usual practice moved forward, with about 275 men and 13 officers in line,[13]
acting as skirmishers for the entire division. Between 3 and q. o'clock in the afternoon
the columns were well under way, and the Bucktails sighted by the Confederate batteries,
placed high up on the mountain, received a storm of shell. Sharpshooters, protected by
rocks and trees, also opened upon them and drove them to cover. All up the mountain side
rocks and boulders abound, and here and there, stone walls. When to these features are
added heavily wooded portions and frequent depressions in the ground itself, some idea may
be gathered of the difficulty of the task laid upon the division. By both armies guns were
planted wherever it was possible to bring them into play.
Quickly taking shelter behind trees
and rocks, the Bucktails brought into play their accuracy of marksmanship. Having in
their hands Sharps rifles, they were enabled to pick off many a Confederate, who,
attempting to reload his inferior weapon, was compelled to partially expose his person.
Then with a cheer, leaving cover for a moment, the regiment rushed forward, and charging
drove the enemy from his first line of defense back to his second and stronger position,
the rest of the division moving up at the same time. General Seymour, confident that his
men could take the first crest, and then by advancing through the valley seize the second,
gave the order to advance. Moving to the place where the fire was hottest he found Colonel
McNeil, and together the two officers encouraged the men. The task was enough to cause the
boldest
205
to hesitate.
The troops were expected to charge uphill, and drive from an eminently strong defensive
position an equal number of opponents[14] With the Bucktails deployed
in single line at intervals of from two to twenty feet the ascent was commenced. At the
rear of Company K, the Eleventh regiment fell into position. Not more than a hundred and
fifty yards separated the combatants. A well-aimed bullet struck the color bearer of the
Eleventh, and immediately a Color-Corporal dashed forward to raise it aloft. Realizing
the peculiar conditions of the battle, and unwilling to see lives uselessly sacrificed,
Lieutenant Welch, of Company K, of the Bucktails, ordered him to desist.
At this time, the condition of the
men was perilous. The Confederates were sheltered more adequately than the Bucktails,
and were doing terrible execution. Captain Irvin sprang to the front, crying,
"Forward Bucktails, drive them from their "position." With a cheer the men
rushed forward, closely followed by the Eleventh, but before he could turn Irvin fell,
wounded in the head. Infuriated by his loss the men charged boldly. The first ridge was
gained and forcing the enemy back, step by step, before dark Seymour's brigade rested in
206
possession
of the second. Magilton's and Gallagher's[15] brigades had performed the
work assigned to them, Reno[16] had moved north as ordered,
while Gibbon had pushed his demonstration up the main road well towards the summit.
If the contest was resumed in the
morning it could have but one result. The way for the army to interpose between the
fragments of the Confederate forces was open, nor as yet had Harper's Ferry been
surrendered. The price paid by the Union General for Turner's Gap was 1,813 men, of which
the Pennsylvania Reserves lost 392. The Bucktail loss was as follows

General Meade in his official report,
after extending praise to General Seymour and his brigade for the successful
accomplishment of the great object of the movement, viz.: the outflanking of the
enemy, says: "To Colonel McNeil, of the First "Pennsylvania Rifles, who with his
regiment has always been "in the advance, I am indebted for ascertaining the exact
position of the enemy."[18]
207
Captain
McGee, who, owing to Colonel McNeil's death at Antietam, made the official report of this
battle, says: "Among "those who particularly distinguished themselves for
gallantry
"on
this occasion I have to mention the following: Captain "Edward A. Irvin (severely
wounded), Captain A. E. Niles,
"Adjt.
William R. Hartshorne, Lieuts. James M. Welch, Lucius "Truman, S. A. Mack, Jr.
(wounded), N. B. Kinsey, David "G. McNaughton, and Sergt.-Maj. Roger Sherman."[19]
No attempt was made during the
evening to descend the mountain on its western side, and the battle of South Mountain
closed[20]
with the oncoming of night. The day's heavy fighting, made still more hard by the
difficult climb, had rendered the
men
thoroughly exhausted. The Bucktails, now reduced to but slightly over two hundred men,
with the adaptability of
seasoned
campaigners, turned in promptly. If the pass was in their possession, the objective of the
campaign was still to be secured, for Lee with his troops, scattered though they were,
lay in the plains below them. McClellan was certain to order an advance by the next morning at the latest.
[1] McClellan seems to have known that the Army of Virginia and Army of the Potomac would be merged into one, prior to the actual accomplishment of the union. General Pope's ideas, do not seem to have been so clear, as on September 4, r862, we find him suggesting corps compositions to General Halleck (O. R. I. XII. iii., p. 8io), and on September 5th, asking "What is my command and where is it?" (O. R I. XII. iii., p. 812.) On the latter date Pope received the following from General Halleck: "The Armies of the Potomac and Virginia being "consolidated you will report for orders to the Secretary of War." (O. R I. XII. iii., p. 8:3.)

'Many greatly exaggerated
statements have been made by both sides as to the relative strength of the contending
forces. BrigadierGeneral Palfrey, after a careful study of the case, credits the
Confederates with having 15 brigades, and the Federals with having x8 brigades, in
action; though of the 18 Federal brigades, 3 were hardly engaged at all. Though he admits
that the Federal forces probably outnumbered the Confederates, he says, ° There is no
reason for supposing that these Federal brigades went into action very much stronger
"than their opponents." (Antietam and Fredericksburg, p. 38, etc.)
Lieutenant-Colonel Allan, however, maintains that the Confederates had only 13,000 to
14,000 men, while McClellan had 30,000. (" Army of "Northern Virginia in
1862," p. 360.) The truth is probably between the two, but had the odds been three to
one instead of three to two, it would have been no mean achievement to have dislodged a
force from such a strong position.

[20] To quote Brigadier-General Palfrey again: "So much of the "battle of South Mountain as was fought at Turner's Gap hardly admits "of precise description. It lasted a long time, from about seven in the "morning till well into the evening, and a good many troops were used "first and last but the ground was so peculiar and so little known to "our commanders, that much precious time and many gallant efforts "were almost wasted, and it was not till the day was near its end that "the Federal advance was conducted with ensemble. There was plenty "of hard fighting, but much of it was sharp skirmishing, and the whole "affair, till near the end, was rather many little battles than one connected battle." ("Antietam and Fredericksburg," p. 33.)
