As the panic deepened, ordinary Americans suffered terribly. A cigar maker named Samuel Gompers who was young in 1873 later recalled that with the panic, "economic organization crumbled with some primeval upheaval." Between 1873 and 1877, as many smaller factories and workshops shuttered their doors, tens of thousands of workers — many former Civil War soldiers — became transients. The terms "tramp" and "bum," both indirect references to former soldiers, became commonplace American terms. Relief rolls exploded in major cities, with 25-percent unemployment (100,000 workers) in New York City alone. Unemployed workers demonstrated in Boston, Chicago, and New York in the winter of 1873-74 demanding public work. In New York's Tompkins Square in 1874, police entered the crowd with clubs and beat up thousands of men and women. The most violent strikes in American history followed the panic, including by the secret labor group known as the Molly Maguires in Pennsylvania's coal fields in 1875, when masked workmen exchanged gunfire with the "Coal and Iron Police," a private force commissioned by the state. A nationwide railroad strike followed in 1877, in which mobs destroyed railway hubs in Pittsburgh, Chicago, and Cumberland, Md.
