Final answer:
Various benevolent societies, church organizations, ladies' aid societies, and the Freedmen's Bureau sent bandages, medicine, and food to the Union Army camps during the Civil War, supporting both soldiers and freed African Americans.
Step-by-step explanation:
The individuals who sent bandages, medicine, and food to the Union Army camps during the Civil War were primarily members of benevolent societies, church organizations, and groups like the United States Sanitary Commission. North Home Missionary Society, Freedmen's Aid Society, and General Conference of the Methodist Episcopal Church are examples of organizations that provided supplies. Women also organized into ladies' aid societies and volunteered for the U.S. Sanitary Commission to support Union soldiers through fundraising, sewing uniforms, and nursing the injured. Additionally, the government created the Freedmen's Bureau which, along with philanthropy and benevolence from Northern cities, helped in providing education and care to freed African Americans. Consequently, throughout the war and especially following the Emancipation Proclamation, there was a significant collaborative effort to support the Union army and newly freed slaves.
