LOL. Well there was no arsenal before the Civil War and doubt there was one during. The Dog River at that time was in the boonies, not easy to get to. The cotton factory had to use a toll road to travel its wares to and from Mobile. Now, it is possible that the Confederate Army, after acquiring the factory grounds, stored arms there. The main building of the factory was a brick, three storied building, 182 feet long by 54 feet wide. It had a square tower at the front four stories high- seventy feet to the top of the belfry. It had 195 windows and it took 750,000 bricks to build. A structure that size could have housed at least 800 or maybe over 1000 men. There were also about 40 houses for the workers and their families to live in, these were used by the enlisted soldiers. The superintendant's home was used by the officers. The only reason the army was there was to build and man the fortifacations there protecting Mobile. Also, it had a waterway that could handle shallow draft steamboats to transfer troops to Fort Gaines. That area was too exposed to invading troops, I doubt they would have risks putting an operational arsenal in that area. It is said Brig. General William E. Baldwin was killed at the Dog River Factory in a riding accident that broke his neck.
