It is by no means enough that an officer should be capable. . . . He should be as well a gentleman of liberal education, refined manners, punctilious courtesy, and the nicest sense of personal honor. . . . No meritorious act of a subordinate should escape his attention, even if the reward be only one word of approval. Conversely, he should not be blind to a single fault in any subordinate.
