Looking for information on Caddo Parish Militia, Capt. Bickman Co. My greatgrandfather was a member of this group for about 2-3 months. He was absent without leave after June. He enlisted April 12,1863. Nothing more has been found . What happened to this group ? It was listed in the National Archives. Surely someone has heard what happened to it. Any thing anyone knows will be greatly appreciated.My greatgrandfather 's name is listed as Caswell Meeks. his son also in this militia was listed as P.Meek He was discharged on the Surgeons certificate Service well done.
