What exotic animal did the confederates bring to the Battle of Vicksburg?

During the Battle of Vicksburg, Confederates brought a war elephant named "Old Bet" to the battlefield. This unusual choice was intended to intimidate Union troops and bolster Confederate morale. The use of an elephant was a rare and exotic strategy, reflecting the desperation and creativity of the Confederate forces at that time. However, the elephant did not significantly influence the outcome of the battle.
