Greg, if indeed you locate a history .I would be interested in anything on Capt. D.A.Briggs 2nd Ind.Cav..Captured at Hartsville,TN..Not sure you might look for a history of the 104th IL.Inf. for a mention of the flag as Col.A.B.Moore 104IL.Inf.was also captured there.I would have to look up as to particulars but, I remeber a CSA flag of truce was ignored during this action that might tie into the captured flag.Jeff Davis mentions in O.R..
