1913's march was quite different from 2013's. In 1913 a woman on a white horse led the women who were "jeered, tripped, grabbed, [and] shoved" and pelted with vulgar language by men along the route who were seemingly encouraged by police, one of whom, according to a report, said "women should stay at home where they belong."
Upon request from the chief of police who sought assistance in 1913 to help control the crowds, the U.S. Secretary of War authorized troop reinforcements. The women were forced by the crowd size to march single file in some parts of the route, and 100 were taken to hospitals. (Read more of the details here in a Library of Congress document.)
