As you stand here, near the middle of Fort Mulligan, its sheer sizebecomes apparent. It is approximately 700 feet east to west and400 feet north to south at its widest point. Surrounding you arethe Fort's intricate inner works called bombproofs, which likelyhoused men, ammunition and some foodstuffs. You are standingbetween two bombproofs and directly in front of you is a third,much larger. The remains of a fourth exists to the left. Thesestructures were covered with logs and a layer of earth that would have stopped opposing artillery fire. These are the structures that were destroyed by Confederate General Jubal Early's forces in January of 1864, after Federal troops had abandoned the post.General Early stated that his men "demolished the works, which contained several bombproof shelters for men, and magazines for ammunition and other stores."
Fort Mulligan was used as a forward post and auxiliary depot tosupply Union troops on their expeditions against Confederateforces. Almost all supplies came 38 miles by wagon train fromthe railroad at New Creek Station (Keyser). These trains, the mail, couriers and scouting patrols were all subject to attack by the McNeill Rangers or other Confederate groups. Only forage for horses was gathered locally, with garrison troops forced to go as far as 15 miles to gather it.
