It was the largest built during the war, but was not intended for defense as much as it was a supply depot.
The Nov. 22nd Murfreesboro (Tn) Post had an article about Fort Rosecrans which was built shortly after the battle of Stones River, Tennessee. The supply base contained inside the walls covered 200 acres and was the scene of much activity throughout the war.
After the war. most of its land reverted to agricultural use, but the west wall and one redoubt survived and acquired by the city. It was transferred to the National Park Service in 1993 and became a part of the Stones River National Battlefield.
