The Irish Brigade at
the Battle of Antietam
By Ranger Mike Gamble
At the
base of the War Department Observation Tower on the Antietam National
Battlefield, the Irish Brigade Monument vividly depicts the courage and
audacity of four Union infantry regiments on the morning of September 17,
1862. This monument, dedicated on
October 25, 1997, not only describes the attack of the Sixty-ninth,
Sixty-third, Eighty-eighth New York and the Twenty-ninth Massachusetts, but also the story of its famed
commanding officer Brigadier General Thomas Francis Meagher. It was Meagher, leading his soldiers against
withering enemy fire in the Sunken Road that epitomized the reputation of the
brigade as one of the most experienced and fearless units in the Army of the
Potomac.
Born in
Waterford, Ireland on August 3, 1823, Thomas Francis Meagher came to New York
City in 1852 after escaping British imposed exile in Tasmania. Meagher had been a member of the “Young
Ireland” movement and was arrested by the British for advocating the violent
overthrow of British rule in Ireland. He
was popular with the large Irish Community in New York where he became active
in Irish political affairs. When the
Civil War began, Meagher used his influence to recruit soldiers for the New
York Militia and raised a company within the Sixty-ninth New York. The unit achieved a good reputation at the
First Battle of Manassas. Returning to
New York, he conceived the idea of forming a brigade of Irish regiments modeled
after the French Army’s Irish Brigade that achieved notoriety for fighting the
British in the Eighteenth century.
Meagher assumed command of the Irish Brigade and was commissioned a
Brigadier General on February 2, 1862.

The
Irish Brigade came to the farm fields outside of Sharpsburg, Maryland as part
of Major General Israel Richardson’s division of Major General Edwin Vose Sumner’s
Second Corps. Because of their battle
record during the Seven Days Battles, Major General George McClellan, commanding the Army of the Potomac, knew that Richardson’s men would insure the
safety of his command headquarters and placed this division near the Pry Farm
until relieved.
From his headquarters, McClellan received
reports of the First and Twelfth Corps attacks against the Confederate left flank
during the early morning hours of September 17, 1862. By 7:30 A.M., Sumner’s
Second Corps received orders to support these attacks that were at a
standstill. Sumner ordered Major General
John Sedgewick’s division to assault the Confederates who had taken a stand in
the woods west of the Hagerstown Pike. Brigadier
General William French followed with his division but veered south in order to
support Sedgwick’s left flank. This
movement took French’s three brigades towards a fallback position that the Confederates
had established in a sunken road south of the Roulette Farm.
Sedgwick’s
division assaulted the West Woods shortly after 9:00 AM.
Unbeknownst to Sedgwick, famed Confederate commander "Stonewall" Jackson, whose men held the West Woods, was just then receiving reinforcements
from Major General Lafayette McLaw’s division that had arrived early that
morning from Harpers Ferry. Jackson also
received assistance from Major General John Walker’s division and Colonel Tige
Anderson’s brigade. Outnumbered by the
Confederates, Sedgewick’s men were hit by a furious assault and driven back
from the West Woods having suffered fifty per cent losses.
Upon
the arrival of Major General Morell’s division at McClellan’s headquarters,
Major General Richardson followed French’s route to the battlefield. The lead brigade of Richardson’s division was
the 1340 officers and men of the Irish Brigade. Passing by the Henry Newkirk
house, they ascended the crest of a second ridge and down a second ravine,
which was an extension of the Roulette Farm Lane. Meager placed the Sixty-ninth New York in the
lead, followed by the Twenty-ninth Massachusetts, the Sixty-third New York and the
Eighty-eighth New York. Brigadier
General John Caldwell’s brigade formed on the left of Meagher and Colonel John
R. Brooke’s Brigade followed in reserve.
Seeing that soldiers from French’s division had taken cover on the uneven ground
north of the Sunken Road, Meagher prepared his brigade for the attack. Leaving unneeded equipment in the Roulette
Lane, the Irish brigade formed their battle line. Upon reaching the Sunken Road, Meagher’s plan directed
“that after the first and second volleys delivered in line of battle by
brigade, the brigade should charge with fixed bayonets on the enemy”.
In the Sunken Road, three of the five brigades
in Major General Daniel Harvey Hill’s division piled up the fence rails on the
lip of the road and placed their best marksmen in the front ranks. Brigadier General George B. Anderson’s
brigade occupied that part of the road directly in the path of the Irish Brigade. Brigadier General Robert Rhodes commanded the
other brigade from the Roulette lane intersection to the Mumma farm lane. At that point, survivors from Brigadier General Alfred Colquitt’s brigade extended the Confederate defense to the Hagerstown Pike.
At
approximately 10:30 AM, the Irish Brigade began its assault on the Sunken
Road. Their regiments were in battle
line formation with the Sixty-ninth New York on the right bordering the
Roulette Lane. To their left were the
Twenty-Ninth Massachusetts, Sixty-third New York, and then the Eighty-eighth
New York anchoring down the end of left flank.
Through the smoke of battle, the soldiers saw a familiar sight. It was Father William Corby, an Irish Brigade
Catholic chaplain, giving his blessing and absolution to the troops.

Clearing the first cornfield they encountered,
the troops tore down a wooden fence and pushed on to a second fence. Brigadier General Meagher ordered the second
fence torn down and eighty volunteers sprung to the task. One volunteer, Private Samuel Wright of the
29th Massachusetts, was shot in the back as he ran back to rejoin
his unit. For his heroic actions,
Private Wright will be awarded the Medal of Honor.
As the
Irish Brigade neared the Sunken Road, Confederate Major General Richard
Anderson’s division surged through the Piper Farm south of the Sunken
Road. Making their way through Mr.
Piper’s apple orchard, Anderson was wounded and replaced with the next officer
in rank, Brigadier General Roger Pryor.
Unable to organize the brigades coming through the Piper apple orchard
and the Piper cornfield, Pryor failed to coordinate troop movements as soldiers
attempted to reach the relative safety of the Sunken Road. The Confederate reinforcements were wading into the fire of Union troops who were now
shooting over the heads of the Confederate men hunkered down in the road. Confederate troops were also taking
casualties from federal artillery batteries located two miles from them on the
east side of the Antietam creek. Four
batteries of twenty pound Parrott rifled cannons were targeting the Confederates
located south of the Sunken Road.
The
Irish Brigade slowly came in sight of the Sunken Road and as planned came to a
halt. Meagher reported “Seated on my
horse, close to the Sixty-ninth regiment, I permitted them to deliver their
five or six volleys, and personally ordered them to charge upon the rebel
columns, while the very same moment I ordered Captain Miller, assistant
adjutant general of the Brigade, and Lieutenant Gosson, first aide on my staff,
to bring up the Eighty-eighth and Sixty-third immediately to the charge. It was my design, under the general orders I
received, to push the enemy on both their fronts as they displayed themselves
to us, and relying on the impetuosity and recklessness of Irish soldiers in a
charge, felt confident that before such a charge the column would give way and
be dispersed”.
Captain
Edward Field of the Sixty-third New York described the action: “The rebels
seemed to have a special spite against the green flag, and five color bearers
were shot down successively in a short time.
As the last man fell even these Irishmen hesitated a moment to assume a
task synonymous with death. Big John
Gleason, Captain of the Sixty-third, six feet seven, sprang forward and
snatched it up. In a few minutes a
bullet struck the staff, shattering it to pieces; Gleason tore the flag from
the broken staff, wrapped it around his body, putting his sword belt over it
and went through the rest of the fight untouched”.
Staying
with the Sixty-ninth, Meagher ordered the soldiers to fix bayonets. In front of the Sixty-ninth, a rebel soldier
screamed “bring them colors in here”.
Two color bearers advanced a few steps, shook their colors in the face
of the enemy and replied ‘come and take them you damned rebels’.
Captain
Patrick Clooney of the Eighty-eighth New York shouted to his men to form their
line when a bullet slammed into his knee.
Struggling to stand up, he ignored pleas from his men to go to the
rear. Two more bullets hit the brave
officer, one in the head and other in his chest. He died instantly.
The Twenty-ninth
Massachusetts took cover behind the rise directly in front of the line. As Colonel Joseph Barnes did not receive
orders from Meagher, his men stayed in position and returned fire.
Failing to coordinate an attack with
all of his regiments, the situation for the Irish Brigade became
desperate. Galloping down the rise to
the Sixty-first New York forming on his left flank, Meagher pleaded for
assistance from Brigadier General Caldwell’s Brigade. Colonel Francis Barlow, commanding the
Sixty-first and Sixty-fourth New York, had orders to remain in position and
regretfully could not support Meagher’s cry for help. Also, Brigadier General Caldwell was not
present in the immediate area to approve such a move. Suddenly, Meagher’s horse
was killed by a bullet and fell, trapping the General under the weight of the
dead animal. Two regimental musicians
acted as stretcher bearers and carried Meagher to the rear.
As
Major General Richardson observed the worsening condition of the Irish Brigade,
he also searched for Brigadier General Caldwell. After hearing that Caldwell was not in direct
command, he angrily shouted “God damn the field officers!” and ordered Caldwell’s
brigade to cease their flanking movement and support the Irish Brigade. With
this order, Barlow led his New Yorkers to a position behind Meagher’s men and
began moving through their ranks. Other regiments of Caldwell’s brigade were
able to obtain a position above the road that enabled them to fire into the
lane.
The
Confederates were caught in a crossfire with Union infantry shooting at them from
their front and from their right.
Colonel John B. Gordon, commanding the 6th Alabama was
carried from his regiment, the victim of five wounds. His replacement, Lieutenant Colonel James
Lightfoot misunderstood an order from Brigadier General Robert Rhodes and led
his men back to the Hagerstown Pike south of the Sunken Road. The other Alabama regiments followed.
With no
support on their left, the Confederates still in position in the Sunken Road retreated
towards the Piper Farm. Soldiers from
Caldwell’s brigade surged forward and were met with furious counter-attacks
from the south as well as from the west.
In the process of directing artillery fire, Richardson was mortally
wounded. He succumbed to his wounds that November.
Action
around the Sunken Road was stabilized when Major General Winfield
S. Hancock took over command of Richardson’s division. The Confederate line had
been pushed to its limits but still held the ground around the Piper farm.
The
Irish Brigade had been in action for less than two hours. It began its attack with 1340 men and had
been reduced to 688. Of the four
regiments, the 29th Massachusetts suffered the lowest loss with 10.2% casualties; the 69th New York suffered the highest casualties, losing 62% of its strength. A
total of 113 men were killed, and 539 wounded. With the action now centering on other parts of the battlefield, the brigade was soon ordered back to the Antietam Creek.
The
assault by the Irish Brigade's assault on the Sunken Road displayed
how costly frontal attacks had become by September 1862.
Within three months, the Brigade was called upon to repeat this same
maneuver. Ironically, many of these
survivors will meet their death near another country road. This one, however, was located in Fredericksburg, Virginia.
