Shelby Foote, noted author of several War of Yankee aggression books, and a talking head on PBS's The Civil War, told a story about a Confederate Veteran who described it this way.
"The yell could not be done at anything less than a full run and it was a cross between a foxhunt yip and a squawling Banshee."
The old Vet, in his words, was too well fed and too comfortable to try and recreate it for the ladies at the gathering.
