I too have been trying to find out more about Border Cavalry Rgt. From the Texas State Archives I received the following concerning my g-grandfather:
Name & Rank: DuBose, J.K., 1st Sgt
Comm. Off: McKamy, William C., Capt.
Organ: Co. K, Border Cav Regt., Col Jas Bourland, Comdg., CSA
Enlist: May 9-64 at Camp Morton for the war
Disch:
Descript: R&F 86; en.off. Lt.Col.Cox; Co. sta. at Camp Lookout O. 31-64; scouting but no Indians seen;
Remarks: moved from Camp Twitty to Camp Lookout, Chickasaw Nation distance 15 miles O.27-64, all quiet at this time; 1 mus. roll (a photostat) dtd. S. 1-64 to O. 31-64.
1. My g-gf would have been in his 40s at that time, old for active campaigning. This makes me suspect it was a "home guard" type Regt., possibly raised after Banks Red River Campaign threatend NE Texas. One source told me the outfit was primarily used to hunt down deserters and/or Union sympathizers...who were apparently somewhat numerous along the eastern Red River.
2. Service in the Indian Territory suggests they were also active in "screening" operations. Removal of US Army outposts at beginning of WBTS (also known as Civil War!)opened the frontier to roving Indian bands whom I understand may have raided as far east as the Fort Worth - Dallas area.
3. Would like to know the locations (as related to current geographical landmarks) of
(a)Camp Morton, Camp Twitty and Camp Lookout
(b)If there is any information on this unit, especially Co. K May - Aug 1864 and Nov '64 through disbandment of unit.
4. My grandfather's "place" was along the Sabine River in SE Hunt Co. (Greenville). Old record obtained by family researcher shows he (Jesse Knighten DuBose) charged with murder, and brother (Dr) Amasa Hamilton DuBose charged with assault (1861) in Hunt Co. Record showed several continuances through 1865. J.K. was killed (according to family legend) from ambush in 1866 -- supposedly by "Yankee sympathizers." His brother, Dr. Amasa settled elsewhere. One brother-in-law (John Hawkins) allegedly "lynched," in a supposedly related matter (could refer to gunshot or hanging) and his death date is stated as 6-25-1866. Some of my reading of the time and place suggests that area of NE Texas was as bloody as the better known warfare along the Missouri/Kansas border. Whether these incidents were tied to pre-CW fighting between pro- and anti- slavery forces or whether they resulted from some of the activities of the Border Cavalry operations poses an interesting speculation.
