Short of an infrared satellite view, I am not committing myself. I did see a reference, once, to some woman, possibly a refugee, living in the uncompleted barracks during the war. Storage was probably at a premium, so, the rest of the barracks might very well have been devoted to that topic. You have seen the Fort Blunt map? It shows the barracks, commissary and magazine (why do people keep calling it, "the powder magazine"? It held more than barrels of powder-musket cartridges, etc., were located there). The WPA, under Grant Foreman's flawed research (this makes me a heretic), reconstructed the hilltop bakehouse and oven (since destroyed and very badly reconstructed in the 1980's) and put a sign up that it was the oven and bakery used during the Civil War. It actually dates to 1867-1868. The recent Osprey book shows the 1868 era chapel as the CW blacksmith shop, when that building was actually not a blacksmith shop until c. 1882.
