O Captain! My Captain!
"O Captain! My Captain!" became one of Whitman's most famous poems, one that he would read at the end of his famous lecture about the Lincoln assassination. Whitman became so identified with the poem that late in life he remarked, "Damn My Captain...I'm almost sorry I ever wrote the poem."
