First Manassas/Bull Run:
http://www.historyanimated.com/BullRunAnimation.html
Birth of the Rebel Yell:
One of the first accounts of the yell was given at the battle of First Battle of Manasses (Bull Run) during then Brig. General Thomas Jonathan Stonewall Jackson's assault at Henry House Hill where the order was given during a bayonet charge to "yell like furies", and was instrumental in routing the Federal forces under General Irvin McDowell back to Washington D.C.
“Then arose that do-or-die expression, that maniacal maelstrom of sound; that penetrating, rasping, shrieking, blood-curdling noise that could be heard for miles and whose volume reached the heavens–such an expression as never yet came from the throats of sane men, but from men whom the seething blast of an imaginary hell would not check while the sound lasted.” -Colonel Keller Anderson of Kentucky's Orphan Brigade
