On October 11, 1860, all the militia units of New York City are ordered to turned out to march in in a parade in honor of the visiting Prince of Wales, the 19-year-old Albert Edward, heir to the English throne, who is visiting New York City at the time. Colonel Michael Corcoran, a native of Carrowkeel, near Ballysadare, County Sligo, refuses to march his 69th Infantry Regiment in the parade to protest against British rule in Ireland. He is removed from command and a court martial is pending over the matter when the American Civil War begins.

Five days earlier, Corcoran refuses tickets to a ball in the prince’s honor, telling those who invited him that he is “not desirous of joining in the festivity.”

As for the order to march, Corcoran says he refuses to ask the sons of Erin to honor the son of “a sovereign under whose reign Ireland was made a desert and her sons forced to exile.” He is also heard to refer to the prince as “the bald-faced son of our oppressor.”

Corcoran’s actions cause a firestorm of outrage around the country and especially in New York. U.S. citizens, most completely ignorant of the conditions under which many of these men had lived in British-controlled Ireland, see the actions of the men of the 69th Infantry Regiment as an insult to American hospitality in welcoming these immigrants to their adopted country, though in truth, the welcome is much less than lukewarm.

Corcoran has written his name forever in the pantheon of Irish heroes in America. New York’s Irish present the regiment with a green flag commemorating the event.

Corcoran is arrested and stripped of his command by New York and a court martial is planned. But before he can be tried on the charge, Fort Sumter is fired upon, and the country is more worried about saving the Union than honoring visiting princes. 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.

Corcoran leads the 69th Infantry Regiment to Washington, D.C., and serves for a time in the Washington defenses building Fort Corcoran. On July 21, 1861, he leads the regiment into action at the First Battle of Bull Run with what is now called the “Prince of Wales Flag” flying proudly above his men.

After promotion to brigadier general, Corcoran leaves the 69th Infantry Regiment and forms the Corcoran Legion, consisting of at least five other New York regiments.

The Mayor of New York City, Michael Bloomberg, unveils Ireland’s national monument to the Fighting 69th in Ballymote, County Sligo, on August 22, 2006. The monument is sculpted by Philip Flanagan. The inscription around the top of the monument reads “Michael Corcoran 1827–1863” Around the base is inscribed “New York Ballymote Creeslough Bull Run.” Underneath the monument is a piece of steel from the World Trade Center, donated by the family of Michael Lynch, who died in the tower on September 11, 2001. Lynch’s family are from County Sligo.
