Post Band (Hart's Island, New York Harbor) (Union)

Brief History
During the American Civil War, Hart Island was used for training of the United States colored troops, and as a Union prisoner of war camp. New York City bought the island from Edward Hunter in 1868, and a 45-acre public cemetery was established on the island. The cemetery expanded through the years, and is known as the "City Cemetery" and a "Potter's Field." Over the next century, the island was home to prisons, reformatories, sanatoriums, drug reforms, homeless shelter, and psychiatric institutions.
