Been there - done that. I'm new here, but not new to research, so I feel your pain. For my off line tree, I download copies of most documents, and print the interesting ones, so I don't have to worry about where it went.
In this case, the only way I know of to get a US Civil War pension application, is to request it from the national archives, which takes many months, if not years, to get to the top of the queue. A cousin requested this copy years ago, and we want to make it available to as many cousins as possible without them having to request it again from the national archives. It's an especially awesome document, as many of the forms are filled out long hand by the applicant, so we get to see their handwriting and signature.
