The Dead Rabbits riot was a two-day civil disturbance in New York City resulting from what was originally a small-scale street fight between members of the Dead Rabbits and the Bowery Boys into a citywide gang war which lasted from July 4–5, 1857.
 Taking advantage of the disorganized state of the city's police force, brought about by the conflict between the Municipal and Metropolitan police, the fighting would spiral into widespread looting and damage of property by gangsters and other criminals from all parts of the city.
 It is estimated that between 800 and 1,000 gang members took part in the riots, along with several hundred others who used the disturbance to loot the Bowery area.
 It was the largest disturbance since the Astor Place Riot in 1849, and the biggest scene of gang violence, unsurpassed until the New York Draft Riots of 1863.
 Order was restored only by the New York State Militia, supported by detachments of city police, under Major-General Charles W. Sandford.
The Dead Rabbits also known as the Black Birds was the media-bestowed name of an Irish American criminal militia gang in New York City, in the 1850s.
 Historian Tyler Anbinder says, "The name so captured the imagination of New Yorkers that the press continued to use it despite the abundant evidence that no such club or militia existed."
 Anbinder notes that, "for more than a decade, 'Dead Rabbit' became the standard phrase by which city residents described any scandalously riotous individual or group."
Leo Bernard Gorcey (June 3, 1917– June 2, 1969) was an American stage and movie actor who became famous for portraying the leader of the group of young hooligans known variously as the Dead End Kids, The East Side Kids, and as an adult, The Bowery Boys.
 Always the most pugnacious member of the gangs in which he participated, young Leo was the filmic prototype of the young punk.
 He was the shortest member of the original gang.
Syksey (fl.
 1840-1849) was the pseudonym of an American criminal and member of the Bowery Boys.
 He was supposedly the lieutenant and longtime companion to Mose the Fireboy during the 1840s, often the storyteller of his feats, and is credited for coining the phrase ""hold 'de but"", a common expression used during the mid-to late 19th century meaning to borrow a dead cigar or to ""bum a smoke"".
 He was later portrayed in Benjamin Baker's play "Mose, the Bowery B'hoy" which performed at the old Olympic Theater in 1849 and later toured throughout the United States during the late 1840s and 50s.
 His pseudonym may have been derived from Bill Sikes, the sidekick of gang leader Fagin from Oliver Twist.
The Hudson Dusters was a New York City street gang during the early twentieth century.
 Formed in the late 1890s by "Circular Jack", "Kid Yorke", and "Goo Goo Knox", the gang began operating from an apartment house on Hudson Street.
 Knox, a former member of the Gopher Gang, had fled after a failed attempt to gain leadership of the gang from then leader, Marty Brennan.
 However the two gangs later became allies during the gang wars against "Gay Nineties" gangs, the Potashes and Boodle Gangs, soon controlling most of Manhattan's West Side as far as 13th Street and eastern Broadway, bordering Paul Kelly's Five Points Gang to the north.
 While the gang dominated the West Side, it constantly battled smaller rival gangs including the Fashion Plates, the Pearl Buttons, and the Marginals for control of the Hudson River docks throughout the 1900s.
 Eventually, it drove the rival gangs out through sheer force of numbers, with over 200 members, not including the Gophers, who numbered several hundred more, controlling the waterfront by 1910.
Reverend Louis or Lewis Morris Pease (August 25, 1818 – May 30, 1897) was an American Methodist clergyman, educator and prominent reformer during the mid-to late 19th century.
 He founded the Five Points Mission and later the Five Points House of Industry, established in New York City's infamous Five Points district, which provided religious teaching and work for the area's predominantly working-class Irish Catholics.
The Chichesters also known as the Chichester Gang along with the Forty Thieves, Shirt Tails, and Kerryonians, were one of the oldest early 19th century Irish Five Points street gang during the mid 19th century in New York City.
 The Chichester Gang was organized by its founder John Chichester.
 The gang got their start by stealing from stores and warehouses and selling the stolen goods to local fences in the 1820s and later became involved in illegal gambling and robbery.
 Notable Chichester gang members were Thomas Reeves, Frederick McKinney, Felix Hayden, George Rice, and George Thomas.
 An ally of the Dead Rabbits against the Bowery Boys, the Chichesters maintained between 50-100 gang members lasting for more than 50 years before being absorbed by the Whyos, much like many of the early gangs, following the American Civil War in 1865.
Hell-Cat Maggie (fl.
 1840–1845) was the pseudonym of an American criminal and early member of the Dead Rabbits.
 She was a well-known personality in Manhattan's Five Points district and a noted fighter, her teeth reportedly filed into points and who wore long claw-like brass fingernails, who fought alongside the Dead Rabbits and other Five Pointers against rival nativist gangs from the Bowery, most especially the Bowery Boys, during the early 1840s.
 Although there is little information on her life, she is one of the earliest female criminals of the "Gangs of New York" era and has been compared to later criminals such as Sadie the Goat, Gallus Mag and Battle Annie, the latter leading the female auxiliary of the Gopher Gang during the 1870s.
William "Billy" McGlory, born McGrory, (1851 – ?)
 was an American saloon keeper and underworld figure in New York City during the mid-to late 19th century.
 He was well known in The Bowery and Five Points districts, owning a number of popular establishments throughout the city, most notably McGlory's Armory Hall, a popular Bowery hangout for members of the underworld in the old Fourth and Sixth Wards.
The Bowery Boys were a Nativist, anti-Catholic, and anti-Irish gang based out of the Bowery neighborhood of Manhattan, New York City in the early-mid-19th century.
 In contrast with the Irish immigrant tenement of the Five Points, one of the worst city slums in America, the Bowery was a much more well-off working class community.
 Despite its reputation as one of the most notorious street gangs of New York City at the time, the majority of the Bowery Boys led law-abiding lifestyles for most of the week.
 The gang was made up exclusively of volunteer firemen—though some also worked as tradesmen, mechanics, and butchers (the primary trade of prominent leader William "Bill the Butcher" Poole)—and would fight rival fire companies over who would extinguish a fire.
 While acting in capacity as a gang (and aided by other Bowery gangs), the Bowery Boys often battled multiple outfits of the infamous Five Points, most notably the Dead Rabbits, with whom they would feud for decades.
 The uniform of a Bowery Boy generally consisted of a stovepipe hat in variable condition, a red shirt, and dark trousers tucked into boots, this style paying homage to their roots as volunteer firemen.

Question:  While acting in capacity as a gang, the Bowery Boys often battled multiple outfits of the infamous Five Points, most notably the Dead Rabbits,  also known by what name?
