The Confederate States Army issued those items necessary for the needs of the troops the field and in battle. These items consisted of uniforms, weapons, accouterments, shoes (most of the time), tentage (some of the time), ammunition, and rations. It did not, however, include camp furniture as a necessary issue item.
What, then, would a soldier have used for camp furniture ? When on active campaign, the answer would probably be either "nothing" or whatever happened to be immediately available (such as a tree stump, log, or rock).
When the soldier was in camp, this might change slightly, but how so?
If a military camp was set up near a town, the soldier might have an opportunity to "forage" for some type of furniture, but that is an "iffy" speculation.
A soldier might be able to purchase furniture in town or from a sutler, but unless he planned on being in that camp for some time, that would not necessarily be a wise purchase.
In period photographs we sometimes see officers' camps with nice folding chairs and tables, but how often do we see enlisted soldiers with these same items? Officers were often allowed to have personal and camp items transported in the regimental supply wagons (depending on their rank and other circumstances), but the same was not true for the private soldier.
If you read the book "Hardtack and Coffee" by John Billings, he devotes at least one whole chapter to the topic of "camp furniture". He relates how on occasion, the troops were able to "liberate" certain items of furniture from the local civilian population to augment their meager camp comforts.
But what I found to be most interesting, was his lengthy commentary on the "most" common item of camp furniture to be found around their camps: the humble hardtack box.
Billings goes on to describe how these boxes were one of the few plentiful sources of wood planks available to them. They would take them apart and use the wood to construct all manner of items.
They would make crude chairs. They would turn the boxes upside down and affix wood legs to make them into tables. Often they would just leave them as is and use them for a chair to sit on.
Since they contained rations, the Army was issuing them and they were always plentiful.
Another item to consider is the small wooden musket ammunition boxes. These likewise would have been issued frequently, and once they were emptied, the army had no further use for them.
Billings does not mention the ammunition boxes in his writing, but he was in the artillery, so they would not have normally been issued to his unit, as they would have been to an infantry company.
Therefore, if you are looking for an appropriate piece of camp furniture, let me recommend either a hardtack box or an ammo box. Both of these items would have been plentiful in the Confederate camps, and once they were emptied of their contents, they were considered expendable by the army.
John Norman currently makes a reasonable copy of the .58 caliber ammo box, nicely painted and stenciled for about $20. I have also talked to him about making a copy of the hardtack box. He has said that he could make them for about $30, as soon as he gets the proper stencil copied (Capt. Brooks has one that he is looking to copy).
