“There is no such thing as a soldier. I see death as a private event, the destruction of the universe in the brain and in the senses of one man, and I cannot see any man's death as a contributing factor in the success or failure of a military campaign.”

To a British military officer (August 1780), as quoted in Washington and the Generals of the American Revolution (1856), by Rufus Wilmot Griswold, William Gilmore Simms, and Edward Duncan Ingraham. J.B. Lippincott, p. 271.

Up Front (1945)
Context: Many celebrities and self-appointed authorities have returned from quick tours of war zones (some of them getting within hearing distance of the shooting) and have put out their personal theories to batteries of photographers and reporters. Some say the American soldier is the same clean-cut young man who left his home; others say morale is sky-high at the front because everybody's face is shining for the great Cause.
They are wrong. The combat man isn't the same clean-cut lad because you don't fight a kraut by Marquess of Queensberry rules. You shoot him in the back, you blow him apart with mines, you kill or maim him the quickest and most effective way you can with the least danger to yourself. He does the same to you.
He tricks you and cheats you, and if you don't beat him at his own game you don't live to appreciate your own nobleness.
But you don't become a killer. No normal man who has smelled and associated with death ever wants to see any more of it. In fact, the only men who are even going to want to bloody noses in a fist fight after this war will be those who want people to think they were tough combat men, when they weren't. The surest way to become a pacifist is to join the infantry. <!-- p. 12 - 14

Source: Calculated Risk (1950), p. 1
Context: A soldier's life in combat is an endless series of decisions that mean success or failure, and perhaps life or death for himself or his comrades. The rifleman crawling through the rubble of a bombed-out street must decide on the best moment to escape enemy fire as he dodges from one doorway to the next. He must take a chance. The general seeking to break an enemy defense line and destroy his forces must decide just when and how to strike and precisely to what extent he dare weaken one sector of his front in order to mass overpowering strength at the main point of attack. He, too, must take a chance, although, in the stilted phraseology of military communiqués, he calls it a "calculated risk".

Light (1919), Ch. XXIII - Face To Face
Context: When you look straight on, you end by seeing the immense event — death. There is only one thing which really gives the meaning of our whole life, and that is our death. In that terrible light may they judge their hearts who will one day die. Well I know that Marie's death would be the same thing in my heart as my own, and it seems to me also that only within her of all the world does my own likeness wholly live. We are not afraid of the too great sincerity which goes the length of these things; and we talk about them, beside the bed which awaits the inevitable hour when we shall not awake in it again. We say: —
"There'll be a day when I shall begin something that I shan't finish — a walk, or a letter, or a sentence, or a dream.".
