On 4-22-1865, MG Price's chief engineer (Capt. J.T. Mackey) testified at Price's Court of Inquiry (OR 41-1-705):
"On the 22nd (we) marched 16 miles, crossing Red River at Kemp's Ferry into Texas. Gen. Marmaduke's Division there took the river route 85 miles to Clarksville, Texas, (while the) main body marched through Bonham, the commands rejoining (at Clarksville) on the 28th or 29th (of November 1864)."
Joel Kemp (1810-1874) owned and operated this "first" Kemp Ferry from 1855 to 1874 that connected Indian Territory (and Fort Washita) across Red River (at GPS: 96d, 21m, 55s W; 33d, 42m, 16s N) past old Fort Warren (and nearby Warren) to Bonham, Fannin County, Texas, 12 miles away. Kemp announced (7-18-1855) the opening of his ferry in the (Clarksville National Standard) as being near Fort Warren. (See http://mulberrytx.com/MulberryTX.com/Kemp.html ) The small community of Ambrose, Texas is located closest to (and just south of) Joel Kemp's Ferry site (with Warren and old Ft. Warren between them), but Ambrose (a small town that lost its railroad and post office) is threatened on three sides by a very large sand & gravel excavation of Red River deposits.
The above cited "river road" (that Marmaduke's Division took) connected Warren east, passing below Mulberry, to Honey Grove, Texas, bypassing Bonham.
After Joel Kemp died in 1874 a "second" Kemp Ferry across Red River was started and operated from about 1876-1898 by two of Joel's sons, Simon Burney (1842-1900) and Joel Carr (1855-1938) Kemp. This ferry crossing was located about 5 miles east (and downriver) of their father's ferry site. Joel's sons' ferry was about 2.5 miles north of Mulberry, Texas. This second Kemp Ferry site subsequently became known as "Hall's Ferry." Fannin County Court records called its county maintained road from the ferry crossing to Bonham (from about 1878-1920), the Kemp Ferry Road, the Old Kemp Ferry Road, and the Hall's Ferry Road. All three referred to the same ferry road (to the Second Kemp Ferry crossing north of Mulberry).
The 1871 U.S. Land Survey of the Chickasaw Nation showed only one road passing Bloomfield Academy (the Kemp area) going south to Bonham, and this road connected to Red River near Warren (Ambrose), the presumed location of Joel Kemp's Ferry crossing. The above GPS coordinates reflect this documented fact.
