The Texas Brigade which included the 3rd, 6th, 9th and 27th Texas Cavalry Regiments crossed the Chattahoochie River Sept 21, 1864, the entire Jackson's Division made the crossing. They were to be attached to Forrest's Corps of Cavalry. This attachment may have been made Sept 23. On the 30th they were near Powder Springs and Gholson's Mississippi Brigade were attached to the Division. 6 Oct they were on the Dallas Road moving west. By the 13th they were in Rome. In 6 days they rode what it took Sherman 110 days

The Brigade may have been passing through the area and had a few skirmishes. Each regiment of the Brigade had between 200 and 300 soldiers at this point of the war. Total Brigade strength was less than 1200. Effectives would be about 500. I find nothing that that they were near Cumming, though the crossing of the Chattahoochie is not that far.

Nothing was impossible for a unit that could do 60 miles in one day when ask. Would concentrate on Colonel Hill. Off the top of my head the 6th did not have a Colonel Hill. John Walter Hill was the Surgeon and B. F. Hill was the Chaplain of the 6th.

The brigade could range as far north as Cumming and as far south as Atlanta in a given day. First to gather intelligence and second to gather forage for the horses. George Griscom the Adjutant of the 9th kept a diary and notes that they kept doing picket, so the ranging was limited. Will Keep looking.
