Frank Leslie’s Illustrated Newspaper reported on a ‘riot’ which occurred on Saint Patrick’s Day 1867 at the intersections of East Broadway, Grand and Pitt Streets, one block below Delancey Street and the Williamsburg Bridge (which was decades from being built by that date).
The parade began on East Broadway, with regiments assembling here (“slush and snowdrifts … disregarded”) to march throughout the city.
A bit after noon, a wagon driver, hemmed in by mounds of snow, got caught at Grand and Pitt street, blocking the parade route. He was immediately set upon by angry marchers. When a police officer interceded to protect the driver, he, too, was assaulted, “knocked down and severely injured by being trampled upon.”
Other officers arrived, and soon Grand and Pitt was the scene of senseless violence. “The Hibernians broke their staves of office and used the fragments as shillelaghs and clubs, with such effect, that the officers were the recipients of several ugly scalp wounds and bruises.” Another report lists the unique weaponry as “sword canes, society emblems and other missiles.” One officer was wounded with a sabre. Soon the street corner filled with policemen, and the violence subsided. [source]
The whole event seemed to last no more than thirty minutes. But the New York Times, a fairly anti-Democrat, anti-Irish paper in the mid 19th century, was truly outraged: “We trust there is no Irishman or Irish American, outside of a small lawless minority, that does not feel keenly the disgrace brought upon such celebrations as that of yesterday, by the wanton and brutal assaults upon the Police.”
