Who faced the challenge of those angry about being drafted riot in New York ?

The New York Draft Riots occurred in July 1863, when the anger of working-class New Yorkers over a new federal draft law during the Civil War sparked five days of some of the bloodiest and most destructive rioting in U.S. history. Hundreds of people were killed, many more seriously injured, and African-Americans were often the target of the rioters’ violence.
