Photograph of U.S. Army Headquarters at Wilmington. A stands in front of the drum barracks ready for loading for trip to Arizona fort. The building is of wood and has two large doors big enough for moving large size goods in and out. In front of the building is a camel with two humps, a man holding the reins of a horse, and a front yard. The building also has an covered porch for a porton of the way. Off to the side, a group of men stand, some of which may be in uniform. It appears that another building is pictured along side the warehouse. It has the same style porch.
