Introduction
Although over one hundred fifty years have passed since the
start of the American Civil War, that titanic conflict continues to
matter. The forces unleashed by that war were immensely destruc-
tive because of the significant issues involved: the existence of the
Union, the end of slavery, and the very future of the nation. The
war remains our most contentious, and our bloodiest, with over
six hundred thousand killed in the course of the four-year struggle.
Most civil wars do not spring up overnight, and the American
Civil War was no exception. The seeds of the conflict were sown
in the earliest days of the republic’s founding, primarily over the
existence of slavery and the slave trade. Although no conflict can
begin without the conscious decisions of those engaged in the
debates at that moment, in the end, there was simply no way to
paper over the division of the country into two camps: one that
was dominated by slavery and the other that sought first to limit
its spread and then to abolish it. Our nation was indeed “half slave
and half free,” and that could not stand.
Regardless of the factors tearing the nation asunder, the
soldiers on each side of the struggle went to war for personal
reasons: looking for adventure, being caught up in the passions
and emotions of their peers, believing in the Union, favoring
states’ rights, or even justifying the simple schoolyard dynamic
of being convinced that they were “worth” three of the soldiers
on the other side. Nor can we overlook the factor that some went
to war to prove their manhood. This has been, and continues
to be, a key dynamic in understanding combat and the profes-
sion of arms. Soldiers join for many reasons but often stay in the
fight because of their comrades and because they do not want to
seem like cowards. Sometimes issues of national impact shrink
to nothing in the intensely personal world of cannon shell and
minié ball.
Whatever the reasons, the struggle was long and costly and
only culminated with the conquest of the rebellious Confederacy,
5
the preservation of the Union, and the end of slavery. These
campaign pamphlets on the American Civil War, prepared in
commemoration of our national sacrifices, seek to remember
that war and honor those in the United States Army who died to
preserve the Union and free the slaves as well as to tell the story of
those American soldiers who fought for the Confederacy despite
the inherently flawed nature of their cause. The Civil War was our
greatest struggle and continues to deserve our deep study and
contemplation.

The Maryland and
Fredericksburg Campaigns
1862–1863
Strategic Setting
By the late summer of 1862, the American Civil War had
dragged on longer than anyone on either side had expected
when the first volunteers marched to war in April 1861. After
losing the opening battles at First Bull Run and Wilson’s
Creek, U.S. forces enjoyed a measure of success. Union armies
and navies had advanced along the Tennessee and Mississippi
Rivers and won significant victories at Forts Henry and
Donelson, and at Shiloh, Pea Ridge, and Glorieta Pass. They
had captured the important cities of Memphis and Nashville,
Tennessee; New Orleans, Louisiana; and Corinth, Mississippi.
Most importantly, for the Union they had secured Maryland,
Missouri, Kentucky, and the New Mexico Territory, as well
as areas of Tennessee, Arkansas, Virginia, North and South
Carolina, Georgia, and Florida.
Although 1862 began with promise elsewhere, Federal
armies failed to make substantial gains in Virginia. Between
March and June, Confederate forces defeated troops of Maj.
Gen. Nathaniel P. Banks’ Department of the Shenandoah
and Maj. Gen. John C. Fremont’s Mountain Department for
control of the Shenandoah Valley. From March to May, Maj.

Gen. George B. McClellan sluggishly advanced the Army of the
Potomac, the principal U.S. land force in the Eastern Theater, to
the outskirts of the Confederate capital at Richmond, Virginia,
but faltered on the verge of success. After General Robert E.
Lee assumed command of the Confederate Army of Northern
Virginia from the wounded General Joseph E. Johnston on 1
June, he took advantage of McClellan’s hesitation. In the Seven
Days’ Battles from 25 June to 1 July, Lee launched a series
of fierce attacks that forced McClellan to retreat down the
Virginia Peninsula to his bases on the James River. Although
the Army of the Potomac halted the rebel onslaught at Malvern
Hill, President Abraham Lincoln ordered a withdrawal to safe-
guard Washington in August, thereby bringing the Peninsula
Campaign to an inglorious end. Having secured the Confederate
capital, Lee continued his offensive and defeated Maj. Gen. John
Pope’s Union Army of Virginia—reinforced with elements from
the Army of the Potomac—at the Second Battle of Bull Run,
twenty-five miles southwest of Washington, D.C., on 28–30
August. The Union battle cry “On to Richmond!” had thus far
proved hollow as Confederate forces wrested the initiative in
the East.
On 3 September, Lee
sought Confederate President General McClellan
(Library of Congress)
Jefferson Davis’ approval to
cross the Potomac River and
invade the North. The general
believed that the weakened and
demoralized state of Union
forces following their recent
defeats provided his army an
ideal opportunity for offen-
sive action. Operationally, Lee
sought to destroy the Baltimore
and Ohio Railroad, a vital east-
west Union supply line; impose
the burden of sustaining his
army on Northern farmlands,
possibly into Pennsylvania;
and encourage Maryland to
secede. Davis recognized the
merits of Lee’s proposal, and
8 9
considering that an immediate invasion might enhance the
chances for gaining French and British recognition of an inde-
pendent Confederacy, Davis quickly gave his assent (see Map 1).
On 4 September, as bands played “Maryland, My Maryland,”
an anthem written by Marylander James Ryder Randall, whose
lyrics implored his native state to secede, the first units of Maj.
Gen. Daniel H. Hill’s Confederate division crossed the Potomac
River into Maryland at Point of Rocks. They cut the Baltimore
and Ohio Railroad’s line, disrupted communications between
Washington, D.C., and Harpers Ferry, Virginia, and advanced
toward Frederick, Maryland. The next day, Maj. Gen. Thomas J.
“Stonewall” Jackson’s Left Wing command crossed the river at
White’s Ford, while Maj. Gen. James E. B. “Jeb” Stuart’s cavalry,
screening the army’s right flank, crossed on 5 September. By 6
September, Jackson occupied Frederick, where he was joined
by Lee and Maj. Gen. James Longstreet’s Right Wing one day
later. When darkness fell on 7 September, most of the Army
of Northern Virginia was camped near Frederick. The force
numbered about 50,000 men.
From his position at
Frederick, Lee could move to
break up the Baltimore and General Jackson
Ohio Railroad just south of (Library of Congress)
town at Monocacy Junction;
disrupt the Chesapeake and
Ohio Canal, whose course ran
parallel to the Potomac; advance
into Pennsylvania, feint toward
Baltimore or Philadelphia; and
threaten Washington. Despite
his proclamation to the people
of Maryland, however, the
largely pro-Union popula-
tion gave the invaders a cool
reception. A small number of
Southern sympathizers turned
out with muted enthusiasm, but
the Confederate army attracted
few recruits and the expected
popular uprising never mate-
rialized. Local farmers and
