From the WGBH Forum Network: "Eighty-five years after Paul Revere made his ride, Henry Wadsworth Longfellow set pen to paper and turned the midnight rider into an instant legend. New research has uncovered some fascinating discoveries about Longfellow's poem. Charles Bahne, independent historian, discusses how the poet came to write about Revere, the poem's publication history, changes made to the text over time, and why the poem isn't historically accurate."
