Excerpt from a letter from U.S. Army major Sullivan Ballou to his wife, July 14, 1861:

The indications are very strong that we shall move in a few days — perhaps tomorrow. Lest I should not be able to write you again, I feel impelled to write lines that may fall under your eye when I shall be no more. …

Forgive my many faults, and the many pains I have caused you. How thoughtless and foolish I have often been! How gladly would I wash out with my tears every little spot upon your happiness, and struggle with all the misfortune of this world, to shield you and my children from harm. But I cannot. I must watch you from the spirit land and hover near you, while you buffet the storms with your precious little freight, and wait with sad patience till we meet to part no more.

But, O Sarah! If the dead can come back to this earth and flit unseen around those they loved, I shall always be near you; in the brightest day and in the darkest night — amidst your happiest scenes and gloomiest hours — always, always; and if there be a soft breeze upon your cheek, it shall be my breath; or the cool air fans your throbbing temple, it shall be my spirit passing by.

Sarah, do not mourn me dead; think I am gone and wait for me, for we shall meet again.

He never sent it. It was found in his trunk after he was killed in the First Battle of Bull Run.
