By the end of the Civil War in 1865, the military bases at Point Lookout had grown into a small city. Besides the hospitals and prison camp, you could find dockyards, saw mills and warehouses - even a railroad, a post office and newspaper.
Point Lookout was also the Southern terminus for the Potomac River Flotilla, a U. S. Navy unit. Flotilla vessels brought supplies up Chesapeake Bay to Point Lookout, where they were transferred to river steamers. These steamers traveled the Potomac, bringing in wounded soldiers and prisoners, as well as supplies.
In time the flotilla outgrew its facilities and moved north to a secluded inlet, called St. Inigoes. The Navy still occupies the inlet today.
