On January 13, 1874, 7000 unemployed New York workers massed in the city’s Tomkins Square for a meeting that had been approved by the Department of Parks. The city’s police board, however, asked the Parks Department to cancel the permit the night before it was to be held. When the workers (who had not been informed nor were there signs in the park) arrived the next morning, they were greeted by 1600 policeman (many of whom were mounted) who brutally attacked them with clubs and drove them from the park. On January 31, 1874 Frank Leslie’s Illustrated Newspaper published a wood engraving with an incendiary (and false) headline: “The Red Flag in New York—Riotous communist workingmen driven from Tompkins Square by the mounted police, Tuesday, January 13th, 1874” by artist Matthew Sommerville Morgan.
