"The arsenal at Mount Vernon, now furnished with steam power and having a good deal of machinery, was considered out of position after the fall of New Orleans, and was moved to Selma, Ala., where it grew into a large, well-ordered arsenal of the best class, under the charge of Lieutenant-Colonel White. It was relied on to a great extent for the equipment of the troops and fortifications in the southern part of the Confederacy."
