The Sixth assembled at its armory at East Fayette and North Front Streets (by the old Phoenix Shot Tower) in the &lt;a href="Old%20Town%2C%20Baltimore"&gt;Old Town /Jonestown&lt;/a&gt; area and headed to Camden. It had to fight its way west through sympathetic Baltimore citizens, rioters and striking workers. The march erupted into bloodshed along Baltimore Street, the main downtown commercial thoroughfare, the way to get to Camden. It was a horrible scene reminiscent of the worst of the bloody "Pratt Street Riots" of the Civil War era in April 1861, over 15 years earlier. When the outnumbered troops of the 6th Regiment finally fired volleys on an attacking crowd, they killed 10 civilians and wounded 25. The rioters injured several members of the National Guard, damaged B. &amp; O. engines and train cars, and burned portions of the train station at South Howard and West Camden Streets. The National Guard was trapped in the Camden Yards, besieged by armed rioters until July 21–22, when President Rutherford B. Hayes sent federal troops and the U.S. Marines to Baltimore to restore order.
