Whoa! Was that Colonel Marcellus Pointer of the 12th Alabama Cavalry?
It's not the same person.
Believe it's Edward Henry Pointer, of Williamson County, TN, who joined Holman's Battalion, Partisan Rangers, which became Co. B of the 11th. TN Cavalry (CSA).
In the '
Military Annals of Tennessee: Confederate' (1886), it lists (at page 708) Private Edward Henry Pointer of the 11th. TN Cavalry being killed on Lick Creek, Hickman County, TN, after he had surrendered on May 7, 1864.
The more detailed description reads (at page 709):
..."Private Edward H. Pointer, a young man of intelligence and promise, was murdered by the Federal troops after he had surrendered. They took his own pistol and shot him. Pointer was on detached service as a scout, and was captured at or near the house of Mr. Bradford, on Lick Creek, in Hickman county, Tenn., on the 7th of May, 1864. The company who murdered him is said to have been commanded at the time by one Captain or Lieut. Creeey."...
This reference is contrary to the contents of the OR previously cited, which referred to Pointer being of the rank of Colonel and being killed in different circumstances of capture.
One can choose which version of events to accept.
