I think I found at least one message in the O.R. that mentions Frank James, of the notorious post war James Gang.

"MAY 19, 1863.—Skirmish near Richfield, Clay County, No.

Report of Capt. Joseph Schmitz, Twenty-fifth Missouri Infantry.

U.S. ARSENAL, CLAY COUNTY, Mo., May 22, 1863...

...From the best information that I can obtain, there were but 16 or 18 men of the bushwhackers, and were under command of one Ferdinand Scott, who was recognized by persons who know him well; so also were the following-named: Frank Turner, L. Easton, Frank James, Louis Vandever, Louis Gregg, and Churchill, and Moses McCoy, the husband of Mrs. McCoy, now on parole at your place. Joe Hart was not with the gang at Richfield on Tuesday evening, but was reported to have met them at the place before mentioned, 12 miles north of Liberty, on Wednesday (by the men at the house they stopped). Hart said then that he came from Saint Joe (direct) and visited Mrs. McCoy.

I have all the old arms of the militia boxed up, and will send them to Saint Joe by the first boat. I wish the arms, also tents for which requisitions are sent in, would be forwarded to this post; also stationery and blank reports.

I am, very respectfully, your obedient servant,

JOSEPH SCHMITZ,
Captain Twenty-fifth Missouri Infantry.

Col. CHESTER HARDING, Jr."
