Aftermath and Significance
For the people of Sharpsburg, the
battle and presence of thousands
of soldiers caused sickness and
death from disease, and great
property damage. Antietam made
feasible the Emancipation Proclamation and reshaped the logistics
of field medicine, ft also influenced
how the nation would memorialize battlefields in the future.
Comrades with wounds of
all conceivable shapes
were brought in and
placed side by side as
thick as they could lay,
and the bloody work of

food Clara Barton (above) brought —Union Soldier George Allen
to his Antietam hospital, Surgeon
Charles Dunn christened her
"The Angel of the Battlefield." In
1881 Barton founded the American Red Cross. She not only provided neutral assistance to soldiers
in war but conceived and put into
practice the provision of aid to
civilians after natural disasters.
Immediately after the battle over 3,500 dead
were buried in farm fields surrounding Sharpsburg (backgroundphoto at right). Eventually
Confederate soldiers were moved to three
local cemeteries. Union men were re-interred
in Antietam National Cemetery, their names
(if known) recorded in the book at right.
The Emancipation Proclamation (right), released
January 1,1863, reshaped the war, freeing slaves in
states in rebellion and giving the Union war effort,
two goals: preserve the Union and end slavery.
Slaves could flee to Union camps and freedom
or even join U.S. fighting forces. Lee's repulse at
Antietam enabled the proclamation, and the two
events kept Great Britain from intervening for the
Confederacy.

Hospitals were set up in barns,
churches, homes, and make-shift
tents (below) to care for over
17,000 wounded soldiers. The

the area "one vast hospital."

care was put in place just weeks
before this battle. Dr. Jonathan
Letterman, chief medical officer,

also adopted triage—a system
of prioritizing casualties by the
severity of their wounds.

TOURING ANTIETAM BATTLEFIELD
Cornfield and West Woods
Sunken Road (Bloody Lane)
Lower Bridge (Burnside Bridge)
O Dunker Church Built in 1852, this modest house of worship for pacifist German
Baptist Brethren became a focal point for
Union attacks the morning of the battle.
© Union Advance During mid-morning
nearly 10,000 Union soldiers moved across
the Mumma and Roulette farms toward
the Confederate center at Sunken Road.
Two Union soldiers were awarded Medals
of Honor for bravery in these attacks.
0
Lower Bridge (Burnside Bridge) About
500 Confederate soldiers held the area
overlooking the Lower Bridge for three
hours. Burnside's command finally captured the bridge and crossed Antietam
Creek, which forced the Confederates
back toward Sharpsburg.
© North Woods Union Gen. Joseph Hooker's men spent the night before the battle
on the Poffenberger farm. At first light the
Union attack advanced south from here toward Jackson's lines. "The stars were still
shining when [Hooker's] skirmishers became
engaged," a soldier would later recall.
© East Woods A small engagement took
place in this area the night before the battle. The fighting also opened here early on
September 17 as Union and Confederate
soldiers exchanged deadly musket volleys,
vying to control these woods.
© Cornfield This 24-acre cornfield saw
some of U.S. history's most horrific fighting. For nearly three hours Hooker and
Mansfield's Union forces battled Jackson's
Confederates. Many regiments on both
sides were cut to pieces. Hays' Louisiana
Brigade suffered over 60-percent casualties in 30 minutes.
0 West Woods Around 9:30 am Gen.
Edwin Sumner's Union soldiers advanced
into the West Woods. The combined firepower of Confederate artillery and attacking infantry drove them back. In 20 minutes
over 2,200 Union soldiers were killed or
wounded.
0 Mumma Farm and Cemetery The only
deliberate destruction of property during the battle was the burning of this
farm. Confederate soldiers were ordered to burn these structures to prevent their use by Union sharpshooters.
Fortunately, Samuel Mumma and his
family had fled to safety before the battle. The Mumma family rebuilt the home
in 1863.
© Sunken Road (Bloody Lane) This farm
lane served as a breastwork for the Confederate center. For about three hours
2,200 Confederates, later reinforced by additional troops, held off the attacks of a
combined Union force numbering nearly
10,000. Finally, just after noon, this thin
gray line collapsed and fell back several
hundred yards to the Piper Farm. The Union
attackers had suffered too many casualties
to pursue their advantage. Seeing the
dead in the road an observer wrote, "They
were lying in rows like the ties of a railroad, in heaps like cordwood mingled
with the splintered and shattered fence
rails. Words are inadequate to portray the
scene."

Final Attack After taking the Lower
Bridge, Burnside moved across these fields
from east to west, pushing back the Confederate right flank. Just as it appeared
that Lee's line was breaking, Confederate
Gen. A.P. Hill's Light Division arrived from
Harpers Ferry to drive Burnside back to
Antietam Creek.

Antietam National Cemetery This hill
was occupied by Confederate artillery—
neither this nor the town cemetery across
the road were here in 1862. At first the
dead were buried where they fell on the
battlefield. Later they were reinterred
here, along with Union soldiers who died
in combat or in hospitals throughout the
region. A total of 4,776 Union soldiers rest
here along with dead from four other
wars. Separate even in death, Confederate
soldiers were buried in Hagerstown and
Frederick, Md. and Shepherdstown, Va.,
now West Virginia.
Visiting Antietam Battlefield
Antietam Battlefield lies north and east of Sharpsburg,
Md., along Md. 34 and 65. The visitor center, north of
Sharpsburg on Md. 65, is open daily except Thanksgiving,
December 25, and January 1. Before starting your tour,
stop at the visitor center to see the exhibits and AV programs that introduce the battle and the Maryland Campaign. Visitor center facilities and most tour route exhibits
are wheelchair-accessible. The park closes 20 minutes after
sunset.
There are interpretive markers at Turners, Fox, and Crampton gaps on South Mountain and at the ford near Shepherdstown, W. Va., where much of Lee's army recrossed
the Potomac River.
Safety and Regulations While touring the park stay
alert to traffic. Bicyclists should use caution descending
hills. Please use trails to minimize contact with stinging
nettles, ticks, and snakes. Do not climb on cannon, monuments, fences, or trees. Relic hunting is prohibited.
