The contributions of more than six hundred Catholic nuns to the care of Confederate and Union sick and wounded made a critical impact upon nineteenth-century America. Not only did thousands of soldiers directly benefit from the religious sisters' ministrations, but both professional nursing and Catholics' acceptance within mainstream society advanced significantly as a result. In To Bind Up the Wounds, Sister Mary Denis Maher writes this heretofore neglected Civil War chapter in rich detail, telling a riveting story shot with suspicion and prejudice, suffering and self-sacrifice, ingenuity, beneficence, and gratitude.
