And he gave during those three years not only his youth but also his health of body. He was weakened at length with malaria and infected with blood poisoning from a wound that he had dressed. Moreover, the experience drained him on the side of his emotions and his nervous vitality until he went home to become at last paralytic and neurotic. The strain upon him he has described with a realism that unnerves one:

I dress the perforated shoulder, the foot with the bullet-wound,
Cleanse the one with a gnawing and putrid gangrene, so sickening, so offensive,
While the attendant stands beside me holding the tray and pail.
I am faithful, I do not give out,
The fractur'd thigh, the knee, the wound in the abdomen,
These and more I dress with impassive hand (yet deep in my breast a fire, a burning flame).

The war allowed Whitman to put into practice all his young manhood's dream of saviorship. It turned him from a preacher into a prophet and a man of action, one who took his earlier message and illustrated it at every point with works. It awakened within him a new ideal of life. He had been dealing heretofore with words:

Words! book-words! What are you?
Words no more, for harken and see,
My song is there in the open air, and I must sing,
With the banner and pennant a-flapping.

No longer does he exult in his mere physical body. Lines like these he now edits from his early editions:

How dare a sick man, or an obedient man, write poems for these States?

Also lines like these:

O to be relieved of distinctions! to make as much of vices as virtues!
O to level occupations and the sexes! O to bring all to common ground! O adhesiveness!
O the pensive aching to be together,—you know not why, and I know not why.

He omits everywhere freely now from the early editions, not from the "Children of Adam," however, though Emerson advised it with earnestness. The Whitmans were an obstinate race. "As obstinate as a Whitman," had been a degree of comparison; and here was one of them who had taken a position before the world and had maintained it in the face of persecution. Retreat would be impossible; but it is noteworthy that he wrote no more poems of sex and that he put forth no more of his tall talk and braggadocio. Swiftly he had become the poet of the larger life: the immaterial in man, the soul.
