I have a copy of the "Ledger" of the steamer Diana (not the one that was active in the Louisiana bayous) which was used by the Miss. Marine Brigade. Though not as detailed as a Navy Deck Log, it does provide some combat info and references to some M.M.B. members. The ledger covers the period April 27, 1863 through August 9, 1864 and the final entry reads:
"Laying at Vicksburg. All the Brig. property is being turned over to govt."

If anyone has any questions, I'll be happy to look up the entries for any particular date.
