Letter to Samuel "Sam" Chapman (June 1907)
Context: Mason and Hunter not only voted against the admission of California (1850) as a free state but offered a protest against it which the Senate refused to record on its Journal, nor in the Convention which General Taylor had called to from a Constitution for California, there were 52 northern and 50 southern men, but it was unanimous against slavery. But, the Virginia senator, with Ron Tucker & Co. were opposed to giving local self-government to California. Ask Sam Yost to give Christian a skinning. I am not ashamed of having fought on the side of slavery, a soldier fights for his country, right or wrong, he is not responsible for the political merits of the course he fights in. The South was my country.

The Art of Poetry on a New Plan (1761), vol. ii. p. 147.
The saying "he who fights and runs away may live to fight another day" dates at least as far back as Menander (ca. 341–290 B.C.), Gnomai Monostichoi, aphorism #45: ἀνήρ ὁ ϕɛύγων καὶ ράλίν μαχήɛṯαί (a man who flees will fight again). The Attic Nights (book 17, ch. 21) of Aulus Gellius (ca. 125–180 A.D.) indicates it was already widespread in the second century: "...the orator Demosthenes sought safety in flight from the battlefield, and when he was bitterly taunted with his flight, he jestingly replied in the well-known verse: The man who runs away will fight again".

Jean-Christophe (1904 - 1912), Journey's End: The Burning Bush (1911)
Context: Christophe returned to the Divine conflict.... How his own fight, how all the conflicts of men were lost in that gigantic battle, wherein the suns rain down like flakes of snow tossing on the wind!... He had laid bare his soul. And, just as in those dreams in which one hovers in space, he felt that he was soaring above himself, he saw himself from above, in the general plan of the world; and the meaning of his efforts — the price of his suffering, were revealed to him at a glance. His struggles were a part of the great fight of the worlds. His overthrow was a momentary episode, immediately repaired. Just as he fought for all, so all fought for him. They shared his trials, he shared their glory.
"Companions, enemies, walk over me, crush me, let me feel the cannons which shall win victory pass over my body! I do not think of the iron which cuts deep into my flesh, I do not think of the foot that tramples down my head, I think of my Avenger, the Master, the Leader of the countless army. My blood shall cement the victory of the future...."
