The annual Civil War Weekend on Governors Island took place this past Saturday and Sunday, with visitors getting a chance to "meet" the men and women of the Governors Island Garrison during the summer of 1863. Here's a look back at the role Governors Island played during that time, noting: "Governors Island in the New York City litany of isles that served the Union during the Civil War as prison camps for captured Confederates. Its Castle Williams and Fort Jay (aka Fort Columbus) housed rebel POWs—troops and commissioned officers, respectively.
Also held there were Union deserters and political prisoners. The island's other Civil War roles included: a base for recruiters and a rendezvous point for recruits, a garrison, a court for military trials, a place of execution, and a School of Practice for U.S.A. Field Musicians."
