The poet Walt Whitman, feeling the profound shock many Americans felt at hearing the news about Custer and the 7th Cavalry, wrote a poem which was quickly published in the pages of the New York Tribune, appearing in the edition of July 10, 1876.
The poem was headlined, "A Death-Sonnet for Custer." It was included in subsequent editions of Whitman's masterpiece, Leaves of Grass, as "From Far Dakota's Cañon."
This copy of the poem in Whitman's handwriting is in the collection of the New York Public Library.
