This multi-layered biography examines five remarkable women who made important contributions to the Union cause at various stages before, during, and following the defining years of the American Civil War. Harriet Tubman, Harriet Beecher Stowe, Clara Barton, Julia Ward Howe, and Sarah Josepha Hale came from backgrounds that ranged from abject enslavement to New York City's elite. Surmounting social and political obstacles, they emerged before and during the worst crisis in American history, the Civil War. Their actions became strands in a tapestry of courage, truth, and patriotism that influenced the lives of millions--and illuminated a new way forward for the nation. In this collective biography, Robert C. Plumb traces these five remarkable women's awakenings to analyze how their experiences shaped their responses to the challenges, disappointments, and joys they encountered on their missions. Here is Tubman, fearless conductor on the Underground Railroad, alongside Stowe, the author who awakened the nation to the evils of slavery. Barton led an effort to provide medical supplies for field hospitals, and Union soldiers sang Howe's "Battle Hymn of the Republic" on the march. And, amid national catastrophe, Hale's campaign to make Thanksgiving a national holiday moved North and South toward reconciliation.
