The sheriff of New York at the time of the Draft Riots had an Irish surname, but he was not assassinated by a gang leader AFAIK.
The Draft Riots were indeed much worse than the movie portrayal. Army troops and police were beaten back at several points. A police captain who tried to return home to check on his property was recognized, beaten and tortured to death. Horace Greeley was nearly lynched and the Tribune Offices attacked. It was a full-scale insuirrection by the Irish, a Civil War in the North, and lasted nearly a week. Two thousand dead, the worst riot in American history.
The Colored Orphan Asylum really was attacked, and a little girl who didn’t make it out in time was killed by the rioters. (I felt the movie downplayed the violence against blacks. Police would come and cut down lynched blacks, and then mobs would take over that corner and string them back up again.)
The Metropolitan Police and the Municipal Police really were at odds, as in the movie, even having their own blue-on-blue riot in 1857.
Battling volunteer fire crews really did send runners out to put a barrel over the fire plug, and sometimes the houses did burn down while they were fighting.
Chinese immigrants were almost all men. They would have run gambling houses and opium dens, but not bawdy houses with dancing girls.
The big gang confrontation between the nativists and the Irish was on July 4-5 of 1857, not during the Draft Riots. According to Asbury, it was the Bowery Boys (nativists) versus the Dead Rabbits and the Plug Uglies (Irish). If the D.R.'s really existed, they certainly had not been “outlawed” at that time.
IIRC, it was true, as implied in the movie, that the ranks of the “nativist” groups were themselves filled with people of Irish descent, including the famous Bowery Boys.
Bill “The Butcher” Poole (not Cutting) was a Bowery Boy. He was fatally shot in a gambling saloon in 1855 by Lew Baker, a gangster from Five Points. Legend holds that he took a week to die, and he really did say “I die a true American,” as the movie’s Big Bill says. The Bowery Boys themselves were not a criminal gang until the late Fifties, but they were definitely interested in elections.
I liked it that the movie portrayed street gangs as politically savvy. I wonder what would happen if today’s street gangs decided to get into electioneering!
I also liked it that some of the Irish in the movie spoke Irish Gaelic.
I was disappointed that Mose the Bowery B’hoy, the trolleycar-toting eight-foot giant with hands the size of Virginia hams who could swim the Hudson in two strokes, was left out of the movie.
