Composure under suspense is chiefly a matter of temperament; of the constitutional outfit with which Nature favors some, and does not others. It may be cultivated by its happy possessor; but when wanting, the sufferer can supply its place only by laborious self-control, the tension of which by itself expends the energies it seeks to maintain, and so imposes limitations of strength that are often insuperable obstacles to achievement, especially if prolonged. The strain of this endurance is prominent among those borne by commanders-in-chief, who can at no moment afford to be lax, nor yet precipitate; and it increases with time at compound interest.

By dint of it principally he reached the eminence which must be attributed to him as a general officer; for it underlay the full, continuous, and sustained play of the very marked faculties, personal and professional, natural and acquired, which he had.
