The real 'Rebel Yell'

Found this awesome old Smithsonian footage of Civil War veterans in the 1930s showing off their 'Rebel yells' -- the famously eerie Confederate war cry. Listening to this, you get a good idea of why the sight of hundreds or thousands of young men charging at you, bayonets at the ready, and howling for your blood would've been so terrifying on the Civil War battlefields!
