Michael Corcoran, Irish American general in the Union Army during the American Civil War and a close confidant of President Abraham Lincoln, is born in Carrowkeel, near Ballymote, County Sligo, on September 21, 1827. As its colonel, he leads the 69th Infantry Regiment (New York) to Washington, D.C. and is one of the first to serve in the defense of Washington by building Fort Corcoran. He then leads the 69th into action at the First Battle of Bull Run. After promotion to brigadier general, he leaves the 69th and forms the Corcoran Legion, consisting of at least five other New York regiments.
Corcoran is the only child of Thomas Corcoran, an officer in the British Army, and Mary McDonagh. Through his mother, he claims descent from Patrick Sarsfield, hero of the Williamite War in Ireland and leader of the Wild Geese. In 1846 he takes an appointment to the Revenue Police, enforcing the laws and searching for illicit stills and distilling activities in Creeslough, County Donegal. He also joins a guerrilla group called the Ribbonmen.
On August 30, 1849, Corcoran emigrates from Sligo to the United States and settles in New York City where he finds work as a clerk in the tavern owned by John Heaney, whose niece, Elizabeth, he marries in 1854.
Corcoran enlists as a Private in the 69th New York Militia. By 1859 he is appointed colonel of the regiment. The regiment is a state militia unit at the time composed of citizens, not soldiers, and is involved in the maintenance of public order. On October 11, 1860, he refuses to march the regiment on parade for the 19-year-old Prince of Wales, who is visiting New York City at the time, protesting the British imposition of the Irish Famine. He is removed from command and a court martial is pending over that matter when the Civil War begins.
Corcoran also becomes involved in Democratic politics at Tammany Hall. He becomes district leader, a member of the judicial nominations committee, an elected school inspector for his ward, and a member of the Fourteenth Ward General Committee. He is one of the founders of the Fenian Brotherhood in America.
With the outbreak of war, the court martial is dropped and Corcoran is restored to his command because he had been instrumental in bringing other Irish immigrants to the Union cause. He leads the 69th to Washington, D.C. and serves for a while in the Washington defenses building, Fort Corcoran. In July 1861 he leads the regiment into action at the First Battle of Bull Run and is taken prisoner.
While Corcoran is imprisoned, the United States makes threats to execute captured Confederate privateers. Corcoran and several other Union prisoners are selected by lot for execution if the United States carries out its threats against the privateers. This event is known as the Enchantress Affair, but no executions are ever carried out by either side. Corcoran is then offered a parole under the conditions that he not take up arms against the Confederacy. Intending to resume his place in the Union army upon his release he refuses the offer of parole. He is appointed Brigadier General of volunteers in July and exchanged in August 1862. His role in the Enchantress Affair and his refusal for parole gains him some attention and upon his release he is invited to dinner with President Abraham Lincoln.
In April 1863 Corcoran is involved in an incident that ends with Corcoran shooting and killing Edgar A. Kimball, commander of the 9th New York Volunteer Infantry Regiment. Corcoran attempts to pass through the 9th New York’s area without giving the required password after receiving the challenge from a sentry. When Kimball intervenes on the side of the sentry, Corcoran shoots him. Corcoran is not charged with a crime or reprimanded, and continues to serve.
Corcoran returns to the army and sets about recruiting more Irish volunteers. He raises and takes command of what becomes known as the Corcoran Legion. Placed in command of the 1st Division, VII Corps he is engaged in the Battle of Deserted House and takes part in the Battle of Suffolk. In late 1863 he is placed in command of a division in the XXII Corps and returns to serve in the Washington defenses. While riding alone in Fairfax, Virginia he is thrown from a runaway horse and suffers a fractured skull. He dies at the age of 36 at the William Gunnell House on December 22, 1863.
New York City Mayor Michael Bloomberg unveils Ireland’s national monument to the Fighting 69th in Ballymote on August 22, 2006. The monument is sculpted by Philip Flanagan.
