As we travel around the eastern United States, we stop at most Civil War sites. We hear of marches, battles, retreats, and on to the next battle. Little did I ever think of how the soldiers, equipment, supplies, etc get from here to there. This fortress, dirt walls is still surviving a hundred years later, 200 acres, holding up to 15,000 troops and having supplies for an army of 65,000 for several months. This, along with railroads, enabled the Union Army to move southeast during the rest of the war. Visiting it, and walking along the interpretative walkways, gave me many new ideas of how this war was fought.
