While visiting the National Archive in Washington for the 2019 FGS conference, we spent time at the National Archive scanning various Civil War pension and Compiled Military Service Records. William D Harper was one of the veterans whose records I scanned.

When you use the scanning room at the National Archive, you can keep copies of the scanned images. I have uploaded them here for convenience and plan to transcribe and abstract them at a future date. For reference purposes, the images at the National Archive are preferred.
