Wall Street bombing

The Wall Street bombing happened on this day in 1920. A horse drawn cart loaded with 100 pounds of dynamite and 500 pounds of cast-iron slugs exploded on the corner of Wall and Broad, right across from the J.P. Morgan headquarters. Thirty-nine people died, most of whom worked in the financial institutions. The attackers were never found, but a note found after the act suggested anarchists:

Remember. We will not tolerate any longer. Free the political prisoners or it will be death for all of you. American Anarchist Fighters!

The political prisoners were two anarchists who had been arrested several days before for murder.
