I do not have any documents that I could send. The Union POW information about Lt. Legg that I cited is contained in his Compiled Service Record in the National Archives. That service record is available on a National Archives microfilm -- Compiled Service Records of Confederate Soldiers Who Served in Organizations from the State of Virginia, Microfilm No. M324, Roll 924. This microfilm can be found at several regional or university libraries, or at the National Archives in DC or at several regional centers run by the National Archives.
