Hope you have had an opportunity to see the Martin oath of allegiance. I've seen post-war documents like this, but not often. It's the oath of allegiance required for a man to exercize civil rights, such as serving on a jury or voting in an election, whether or not he had served in the Confederate army. It's signed by a police board member, not a U.S. military officer, and makes no statement about Martin ever being "disloyal", serving in the Confederate army or being a civil officer of any kind, not a single word.

This man could have been a scalawag or a carpetbagger recently moved to Mississippi from some other state. Note that the man's residence is not stated, nor are we informed where this document was signed. It simply reads "State of Mississippi" across the top. He could have been a former Confederate; maybe a citizen too old to have been in the army.

Date beside the signature is October 2, 1865.
