As the American Civil War was beginning, Whitman published his poem "" as a patriotic rally call for the North. Whitman's brother George had joined the Union army and began sending Whitman several vividly detailed letters of the battle front. On December 16, 1862, a listing of fallen and wounded soldiers in the "New-York Tribune" included "First Lieutenant G. W. Whitmore", which Whitman worried was a reference to his brother George. He made his way south immediately to find him, though his wallet was stolen on the way. "Walking all day and night, unable to ride, trying to get information, trying to get access to big people", Whitman later wrote, he eventually found George alive, with only a superficial wound on his cheek. Whitman, profoundly affected by seeing the wounded soldiers and the heaps of their amputated limbs, left for Washington on December 28, 1862, with the intention of never returning to New York.
