1. Political Prisoners Marker

Inscription. Among the notable political prisoners confined in these rooms were James Murray Mason and John Slidell, two Confederate envoys to Great Britain. Their arrest on board the British steamer Trent provoked an international incident and nearly brought Great Britain into the Civil War. The envoys were released after two months imprisonment on order from President Lincoln in January, 1862. Alexander H. Stephens, Vice-President of the Confederacy, was imprisoned for six months after the end of the War. He was at first held in solitary confinement, but later enjoyed more comfortable quarters, special meals and access to the fort library.

Welcome to Fort Warren-It was built more than 150 years ago-a fort on an island, a key to the coastal defense of a new nation. It was transformed into a prison during the Civil War, housing hundreds of Confederates within its granite walls, ordinary soldiers and high level politicians alike. It served our nation for more than 85 year as a vigilant sentinel in the harbor. It made over into a park is an extraordinary island setting. Welcome to Fort Warren, on Georges Island. Welcome to the Boston Harbor Islands National Recreation Area
