Great difficulty was found during the operations before Corinth in distinguishing the two Shermans. The soldiers solved the problem by giving each Sherman a nickname. T. W. Sherman was called "Port Royal Sherman," in allusion to his services in South Carolina, while W. T. Sherman was known by the somewhat inappropriate title of "Steady-old-nerves," in contradistinction to the other, who, as before stated, was more timidly nervous. Mr. Lincoln, with some recollection of this coincidence of names on his mind, asked General Grant, on being introduced to General Sherman, if he was W. T. or T. W., and laughed with boyish glee at the "joke on Sherman." As another natural result of Sherman's nervous energy, he has acquired the habit of decision in the most perfect degree, and his peculiar organization has tended to make him practical as well as petulant. He never seems to reason, but decides by intuition, and, in this respect, has something of the mental as well as bodily peculiarities of the gentler sex, who are said to decide intuitively. But Sherman is by no means a woman--he would have been a shrew had he been--and possesses not one particle of the sex's beauty or gentleness. Sherman jumps at conclusions with tremendous logical springs; and, though his decisions are not always final, they are in effect so, for, if he is forced to retire an inch, his next jump will probably carry him forward an ell. Facts are the only argument which prevail with him, and the best arguments of wise men are wasted in endeavoring to convince him without undeniable facts at hand. Obstinate, and vain, and opinionated as he is, and indisposed as he may be to listen to or heed the arguments of equals or inferiors, he never hesitates to sink all opposition before the orders of his superiors, and pay the strictest deference to their views when expressed authoritatively. I have before said this nervousness of mental and bodily organization was the main-spring of Sherman's character. From it result not only his virtues, but his faults, and as man and commander he has many. He is as petulant as a dyspeptic; excessively gruff, and unreasonably passionate. His petulance does not, however, prevent his being pleasant when he is disposed; his gruffness does not destroy all his generosity, and his passionate moods are usually followed by penitence. His fits of passion are frequent but not persistent, and, though violent, are soon appeased. His gruffness often amounts to positive rudeness. While in command at Louisville in 1861, the wife of the rebel commander Ingraham passed through the city _en route_ to the South. The lady, who was rebelliously inclined, pleaded consumption as her excuse for wishing to inhale the Southern air. Sherman gruffly advised her to "shut herself up in a room and keep up a good fire--it would do her just as much good." He often replies in this petulant tone to both sexes, particularly if the person addressed has no business of importance.
