There is an account of Lincoln reading Whitman's Leaves of Grass poetry collection in his office, and another of the president saying "Well, he looks like a man!" upon seeing Whitman in Washington, D.C., but these accounts may be fictitious. Lincoln's assassination in mid-April 1865 greatly moved Whitman, who wrote several poems in tribute to the fallen president. "O Captain! My Captain!", "When Lilacs Last in the Dooryard Bloom'd", "Hush'd Be the Camps To-Day", and "This Dust Was Once the Man" were all written as sequels to Whitman's collection of poetry Drum-Taps. The poems do not specifically mention Lincoln, although they turn the assassination of the president into a sort of martyrdom.
