H. W. Halleck,
Elements of Military Art and Science
“ To watch the approach of an enemy, to see him move up and display his massive columns, his long array of military equipments, his fascines and scaling-ladders, his instruments of attack, and the professional skill with which he wields them, to hear the thunder of his batteries, spreading death all around, and to repel, hand to hand, those tremendous assaults, which stand out in all their horrible relief upon the canvass of modern warfare, requires a heart at least as brave as the professional warrior exhibits in the pitched battle. ”
