The Civil War pension file for Alfred Butler is not at the National Archives (two requests for it came back with the same result--not there). Apparently it is at the Veteran's Administration and I will need to make a Freedom of Information Act request to obtain it. Butler died in 1895, his children later received a pension (but only until they were sixteen), and his widow may have received some sort of pension as well. Her marriage to another veteran after Butler may have muddied the waters just a bit.
Here's Butler's card which was discussed in an earlier post.
I have already sent a request. Stay tuned! I know I am.
