I found two D. F. Rogers in Kentucky units. It's possible that D. F. of the 3rd Mounted Infantry may have reupped with the 3rd Cavalry after recovering from his illness. These are two separate outfits serving in different areas.

The only records on Drury are Federal POW records, there are no company muster reports in his file.

Hope this may help.
