Pioneers! O Pioneers!
"Pioneers! O Pioneers!" is a poem by American poet Walt Whitman. Published in Drum-Taps in 1865, the poem expresses Whitman's fervor for the Westward expansion occurring in the U.S. in the mid-19th century, as exemplified in the pioneers traveling the Oregon Trail, the miners of the California Gold Rush, and the workmen completing the first transcontinental railroad.
