American Civil War

Brig. Gen. Thomas Francis Meagher

The Irish Brigade was an infantry brigade, consisting predominantly of Irish Americans, that served in the Union Army in the American Civil War. The designation of the first regiment in the brigade, the 69th New York Infantry, or the "Fighting 69th", continued in later wars. The Irish Brigade was known in part for its famous war cry, the "faugh a ballagh", which is an anglicization of the Irish phrase, fág an bealach, meaning "clear the way". According to Fox's Regimental Losses, of all Union army brigades, only the 1st Vermont Brigade and Iron Brigade suffered more combat dead than the Irish Brigade during America's Civil War.

Formation and subordinate regiments

The formation of an Irish Brigade was authorized by the Secretary of War Simon Cameron in September 1861. The brigade originally consisted of the 63rd New York Infantry, the 69th New York Infantry, and the 88th New York Infantry. The three New York regiments were soon joined by a predominately "Yankee" regiment from Massachusetts, the 29th Massachusetts. The 29th was never fond of being brigaded with three Irish "Fenian" regiments from New York and soon after the Battle of Antietam the 29th was replaced by the 28th Massachusetts Infantry regiment, made up mostly of Irish Immigrants. Soon after that, the City of Philadelphia offered a regiment to the brigade and soon after the 116th Pennsylvania Infantry was added to the brigade, bringing the total number of regiments in the Irish Brigade to five.

There were three core regiments of the Irish Brigade, the 69th, 88th, and the 63rd. The 69th New York Volunteers, was largely made up of the pre-war 69th New York Militia, a unit which first gained notoriety prior to the Civil War, when Colonel Lt Col Patrick Daniel Kelly and later commanded by Major then Colonel Richard C. Enright.[4] The 88th was numbered out of sequence after the British 88th Connaught Rangers, and was the 2nd Regiment Irish Brigade. After Chancellorsville, the new Brigade Commander, Col Patrick Kelly of the 88th, formed these "core" NY regiments, now together only numbering 220 effectives, into a single battalion under the flag of the 88th.

After Bull Run, brigadier general and designated the brigade's commander. Before the war, he was a leading agitator for Irish independence from Britain. A visible participant in the failed Rebellion of 1848, he was afterward tried and sentenced to death (commuted to life imprisonment in Australia, but he escaped to San Francisco CA). Gen. Meagher's battle sword, made by Tiffany & Co, is now on permanent exhibit at the Fredericksburg and Spotsylvania National Military Park.

Leaders of the Federal Government were reluctant to form ethnically based brigades, which would undermine the notion of a Union. However, by mid-1861 the formation of an ethnically based, Irish brigade served two purposes for the North. First of all, it warned Britain (which appeared to be favoring the Confederacy, or at least openly deliberating its entry into the conflict on their behalf) that there could be Union-supported consequences in Ireland if Britain intervened (most of the brigade's leadership were known Irish revolutionaries). Secondly, it served to solidify Irish support for the Union. Many Irish were divided between supporting the Confederate States in their struggles for independence or to preserve the Union, which gave the Irish a set of rights and freedoms under the Constitution but which they had to struggle to obtain. There were also concerns by some Irish about a flood of freed slaves migrating north and competing for the lowly jobs for which they already had to scrabble. An ethnically based brigade would thus solidify the support of the largest Catholic minority for the Union cause. Several officers were permitted to purchase and carry non-regulation model 1850 Staff and Field officer's swords bearing a large four-leaf clover pierced into the hand guard. Having their own paid Catholic chaplains within the brigade implied a social acceptance for Irish Catholics which had eluded them in the antebellum period. Their head chaplain was Fr. William Corby, CSC, a Holy Cross priest and future president of the University of Notre Dame. He became famous for his giving conditional absolution to the troops of the Irish Brigade before the Battle of Gettysburg.

The Irish Brigade distinguished itself from the rest of the Army of the Potomac by Meagher's insistence on arming the 8 line companies of each NY regiment with Model 1842 smoothbore muskets, an obsolete weapon that was largely phased out during 1862, because he wanted his men to be able to fire buck-and-ball shot (a .69 caliber musket ball with four smaller balls), which produced a shotgun effect in close-range combat and could not be used with rifles. The three original New York regiments carried Model 1842 muskets all through the AoP's campaigns and battles in 1862-63, using buck-and-ball shot with deadly effect in the Wheatfield on July 2 at Gettysburg. The 2 Light companies of each NY regiment were issued with either Springfield or Enfield rifles and with these sniped at Pettigrew's command during Pickett's Charge. The 28th Massachusetts (which joined in October 1862) had Enfield rifles and were with the 6 company NY "light Battalion" often detailed for skirmishing duty.

Meagher assumed his brigade would perform most fighting at close range where smoothbores were effective, and his officers generally agreed. The majority of the soldiers continued to use their Model 1842s through the Overland Campaign until the depleted outfit was temporarily broken up in June 1864. The 116th Pennsylvania was separated from its fellow regiments and finally got Model 1861 Springfield rifles. Ordnance records also indicate that the New York regiments received the newer weapons as well. In any case, by 1864, officers had at last realized the power of rifles and firing was now typically being done from distances of up to 200 yards. There are relatively few complaints on record from the enlisted men about their outdated muskets, although one veteran of the 88th New York recalled that "we were sometimes at a disadvantage because of the short range", and that he had to pick up a discarded rifle from the field at Antietam to deal with Confederate skirmishers.[5]

Before the full five regiments of a typical brigade could be raised, the unit was called to combat. In March 1862 the brigade, composed of the 63rd, 69th, and 88th New York regiments, was assigned to Major General Edwin V. Sumner's division in the Army of the Potomac as the 2nd Brigade and shipped to the Virginia Peninsula. While the Army of the Potomac crept slowly toward Richmond, a fourth regiment joined the brigade: the 29th Massachusetts, a regiment formed mainly of Puritan descendants. Massachusetts had pledged to provide an Irish regiment, intending to send the 28th Massachusetts, but that Irish regiment was not complete when the Army of the Potomac went into action. Instead, the next available unit, the 29th, was sent.

Despite their divergent backgrounds, the 29th Massachusetts and the rest of the brigade fought well together, earning plaudits for hard campaigning during the George B. McClellan.

After Pope's defeat at Second Battle of Bull Run (Second Manassas), Gen. Robert E. Lee took the offensive, moving into Maryland. McClellan and the remainder of Army of the Potomac were rushed north. The brigade's new recruits, approximately a tenth the number that Meagher had hoped to raise, joined the unit at Tennallytown, Maryland, in time to march in pursuit of the Confederates.

On September 17, 1862, the Union and Confederate armies met at Sharpsburg, Maryland, in the Battle of Antietam. Command confusion led to the disjointed use of the II Corps, and instead of supporting renewed assaults on the Confederate left at the West Woods, the Irish Brigade found itself facing the center of the Confederate line, entrenched in an old sunken farm road. The brigade again acted conspicuously, assaulting the road, referred to after the battle as "Bloody Lane". Although unsuccessful, the brigade's attack gave supporting troops enough time to flank and break the Confederate position, at the cost of 60% casualties for the Irish Brigade.

The brigade suffered its most severe casualties in December at the

After the Battle of Fredericksburg, Gen. Meagher again requested to recruit the brigade back to strength. This time the request was denied. In May 1863, the brigade sustained further casualties at the Battle of Chancellorsville, Meagher repeated his request to recruit replacements, was denied, and resigned his commission in protest. Meagher was replaced by Colonel Patrick Kelly.

Leading up to the Battle of Gettysburg, the brigade recovered several hundred of its injured from Fredericksburg and was able to field nearly 600 men - in reality, barely at regimental size. At Gettysburg, the brigade distinguished itself in the Wheatfield under the command of Col. Kelly as the 2nd Brigade of the 1st Division (Brigadier General John C. Caldwell) of the II Corps (Major General Winfield S. Hancock). The brigade has a monument on the Loop on the Gettysburg Battlefield.

While continuing to serve with distinction, casualties continued to increase and by June 1864 the Irish Brigade had been reduced to regimental size, and its commander Richard Byrne killed. The US Army disbanded it and incorporated the remaining elements of the brigade into the 3rd and 4th Brigades of the 1st Division, II Corps.

A Second Irish Brigade was reformed from the old Irish Brigade of the 63rd, 69th, and 88th New York, 116th Pennsylvania, and 28th Massachusetts Regiments as well as the addition of the 7th New York Heavy Artillery (later replaced by the 4th New York Heavy Artillery in early 1865).

Modern history

The lineage of the Irish Brigade has been officially assigned to "Fighting 69th" of the New York National Guard, which is the only currently active military unit that formed part of it.

The "Fighting 69th" fought in World War I as part of the Rainbow Division. For bravery displayed in Lorraine, Champagne-Marne, and Meuse-Argonne, the Medal of Honor was awarded to regiment members, including William Joseph Donovan and Richard O'Neill. By World War II, the Irish influence in the regiment had diminished somewhat, but the regiment served with distinction in the Pacific Theater as part of the 27th "New York" Infantry Division.

Since 1907, the Fighting 69th has been a unit of the New York National Guard.

1st Battalion, 69th Infantry served with distinction in Iraq from 2004-2005. The unit fought in and around Baghdad, most notably securing Route Irish and the surrounding area of Baghdad suburbs, and companies from it have since served in Afghanistan.
