They're in the National Archives, but unless you're interested in special orders like this one, I wouldn't lead anyone to expect a special revelation here. The substance of what's written in the order is represented in the card filed with the soldier's service file. The man was detailed - that's about it.

Going to Washington to find that record would be like climbing a mountain in Tibet to find someone who could tell you what do do with your life. Of course, once you travel across the world and climb the mountain, the Tibetan monk tells you, "Go home and find a job."
