I have written before about the charm of U.S. Grant's memoirs. [You can read his autobiography online.] It is easy to see why Grant and Mark Twain became friends. An excerpt:
On the evening of the first day out from Goliad we heard the most unearthly howling of wolves, directly in our front. The prairie grass was tall and we could not see the beasts, but the sound indicated that they were near. To my ear it appeared that there must have been enough of them to devour our party, horses and all, at a single meal. The part of Ohio that I hailed from was not thickly settled, but wolves had been driven out long before I left. Benjamin was from Indiana, still less populated, where the wolf yet roamed over the prairies. He understood the nature of the animal and the capacity of a few to make believe there was an unlimited number of them. He kept on towards the noise, unmoved. I followed in his trail, lacking moral courage to turn back and join our sick companion. I have no doubt that if Benjamin had proposed returning to Goliad, I would not only have “seconded the motion” but have suggested that it was very hard-hearted in us to leave Augur sick there in the first place; but Benjamin did not propose turning back. When he did speak it was to ask: “Grant, how many wolves do you think there are in that pack?” Knowing where he was from, and suspecting that he thought I would over-estimate the number, I determined to show my acquaintance with the animal by putting the estimate below what possibly could be correct, and answered: “Oh, about twenty,” very indifferently. He smiled and rode on. In a minute we were close upon them, and before they saw us. There were just TWO of them. Seated upon their haunches, with their mouths close together, they had made all the noise we had been hearing for the past ten minutes. I have often thought of this incident since when I have heard the noise of a few disappointed politicians who had deserted their associates. There are always more of them before they are counted.
