Hospital Sketches (1863) is a semi-autobiographical novella by Louisa May Alcott, based on letters she wrote while serving as a volunteer nurse during the American Civil War. The story follows "Nurse Periwinkle," Alcott's witty alter ego, as she journeys to Washington, D.C., to care for wounded Union soldiers in a makeshift army hospital. Blending humor with poignant realism, the narrative depicts the harsh conditions, the suffering and courage of the soldiers, and the emotional toll on caregivers. Alcott's vivid sketches challenged romanticized views of war and brought her widespread recognition, foreshadowing the success of Little Women five years later.
