The Woman Suffrage Parade held on March 3rd, 1913. It started off alright but ended in widespread attacks leading to many injuries due to mostly male crowds jeering and harassing marchers toward the end of the parade.
After charges that physical attacks were allowed by the DC police on the Suffragists, the US Senate's Sub-Committee of the Committee of the District of Columbia held hearings and found the police negligent of protecting the paraders. The DC Superintendent of Police was replaced following the hearings.
According to the New York Times March 1913, anti-vote women golfers prepared tar and feathers in preparation for punishing Suffragettes if they attepmted to plant "Votes for Women or No Golf" signs on the course. After the vigilance was relaxed, the Suffragettes were able to sneak on the golf course and plant their sign with no tar/feather punishment.
