In downtown St. Louis, Missouri, nervous Union troops, thinking they were shot at, fire on civilians, killing six
The tense atmosphere in St. Louis, Missouri helped cause tragedy when a contingent of Union troops marching on Seventh Street, between Olive and Locust Streets in the city, thinking they had been fired upon, loosed a volley of musket fire. Much of this struck the building housing the Recorder's Court, which was in session. Six civilians were reported killed. (By John Osborne)
