On July 20, 1919, a White man and an African American man were arguing about World War I. The fight got heated and the black man pulled a gun and shot wildly down the street. Some of the bullets hit civilians, with one striking George Doles of 231 East 127th St while he was in his ground floor apartment. Another hit Henrietta Taylor, who was sitting on a stoop on 228 East 127th Street. While the two were rushed to a Harlem hospital, word spread that a riot was about to start, and when police arrived on the scene about a thousand black people were present on the block between 2nd and 3rd Ave. As police attempted to clear the streets they were fired upon from surrounding buildings.
