David E. Twiggs was known as the "Bengal Tiger" as well as the "Horse" to his men:
"In the midst of scenery like this, 'Old Davy' Twiggs appeared like a perfectly natural feature. His robust and capacious body, powerful shoulders, bull-neck, heavy, cherry-red face, and nearly six feet of erect stature represented physical energy at its maximum. With bristling white hair and, when the regulations did not interfere, a thick white beard, he seemed like a kind of snow-clad volcano, a human Etna, pouring forth a red-hot flood of orders and objurgations from his crater of a mouth ; and he was vastly enjoyed by the rough soldiers even when, as they said, he 'cursed them right out of their boots.'
"In a more strictly human aspect he made an excellent disciplinarian, and he could get more work out of the men than anybody else in the army; but as a warrior, while he always looked thirsty for a fight, he was thought over-anxious to fight another day to be, in short, a hero of the future instead of the past ; and as a general, Scott had already said that he was not qualified 'to command an army either in the presence, or in the absence of an enemy.' His brains were, in fact, merely what happened to be left over from the making of his spinal cord, and
the soldiers' names for him the 'Horse' and the 'Bengal Tiger' classed him fairly as regarded intellect."
