Arthur Peronneau Ford, Life in the Confederate Army
“ In the assaults of the Federals the cries were regular, like "Hurrah! Hurrah! Hurrah!" simply cheers, lacking stirring life. But the Confederate cries were yells of an intensely nervous description; every man for himself yelling "Yai, Yai, Yi, Yai, Yi!" They were simply fierce shrieks made from each man's throat individually, and which cannot be described, and cannot be reproduced except under the excitement of an assault in actual battle. I do not know any reason for this marked difference unless it was in the more pronounced individuality of the average Confederate soldier. ”
