Yes, your information is more correct than what I was trying to summarize.
Sulphur Springs had both Commissary and Quartermaster operations and details of as many as 50 men were assigned to the officers of these duties to do everything from bookkeeping to repairing the roads in the area to handle in at least one case one shipment of 70,000 bushels of corn for just one of five brigades in the area in the late Winter and early Spring of 1863. In another case in the Fall of 1862 the Commissary Department at Sulphur Springs recieved a Texas cattle herd of 135 head shipped from little Rock to Pine Bluff by steamboat and then drove by herders the 10 miles to Sulphur Springs. That must have been a sight to see a cattle drive from Texas to Little Rock and then to Pine Bluff. Was Paula's Morgan Griffith one of those drovers?
As I said my explaination to Paula about the activities at Sulphur Springs was very broadly generalized. But I was, crudely perhaps, trying to make my point to her about what her ancestor Morgan Griffith was doing.
And that was that from the Summer of 1862 until August 1863 that Sulphur Springs was a major base of operation for Confederate forces for the recieving and distribution of ordinance and commissary supplies not only for the defence of the Lower Arkansas River Valley, But also operations to harrass enemy shipping on the Mississippi River. And even support Gen. John G. Walkers Texas division and the Arkansas troops that took part in the Northern Louisiana campaign of 1863 that lead to the Battle of Millikins Bend.
