What happened to these 9 soldiers' graves?

I was researching the history of Newton Co and I came across somethng that grabbed my curiosity and I am hoping someone can help me out.
On the website
I read this passage:
Onward rushed the engineer. All passed over except the hindmost car. The bridge had swerved out of plumb, and into the raging waters with nearly one hundred soldiers the rear car was precipitated. "Help!" was the cry, but there was no help. The cry reached the camp. "Fly to the rescue!" was the command, and in less time that I can tell the story every Indian was at the scene. It was there that Jack Amos again displayed his courage and devotion to the Confederate soldiers. I must not omit to say, however, that with a like valor and zeal Elder Williams, another full-blood Indian soldier, proved equal to the emergency. Jack Amos and Elder Williams both reside now in Newton County. Williams is now an ordained Baptist minister, having been a gospel student under the venerable and beloved Rev. Dr. N.L. Clark, now living in Decatur, Newton County, and father of our Dr. Clark, of Meridian. Led by these two dauntless braves, every Indian present stripped and plunged into that raging river to the rescue of the drowning soldiers. Ninety-six bodies were brought out upon a prominent strip of land above the water line. Twenty-two were resuscitated and returned to their commands, and all the balance were crudely interred upon the railroad right of way, where they now lie in full view of the passing train, except nine, who were afterwards disinterred by kind friends and given a more honorable burial. Officiating at this terrible calamity were Lieut. TH Gresham, Lieut. Ben Duckworth, and Corporal John Blakeley, who was at that time at home on a furlough from Spann's Battalion of Cavalry at Mobile. This lonely burial spot so far seems unkept by the tender care of any friendly hand. At no time as yet have these unmarked graves been numbered among those who share the wreaths and bouquets of flowers by the hand of our kind and loving Daughters on Decoration Day, yet this sad neglect will, it is hoped, soon have its end. It is the purpose of Camp Dabney H. Maury to erect a twin shaft upon the spot where these dead martyrs repose, commemorating alike the memory of these Confederate heroes and perpetuate the testimonial of the patriotic devotion exhibited by the Choctaw Indian braves, whose prowess and fidelity to the Confederate cause entitle them to the respect of our Confederate soldiery everywhere and to all lovers of the true and the faithful wherever found.

My question is this: Does anyone know where the burial place is for those 9 soldiers?
