By 1862 the Confederate depot system was beginning to get up and running. Especially towards the end of the year government produced clothing would have been very common place in the ANV. Regardless of whether a soldier was wearing government or private made/state furnished clothing every Confederate infantryman would, in theory, be equipped with the following:
Haversack - for carrying rations. CS produced varieties are typically made from a cotton drill material and are generally plain canvas. Tarred, or oil cloth examples were also issued. Given the ANV's numerous encounters with Federal forces in 1862 it is probable that a soldier may have carried a captured Federal haversack of the M1851 pattern, or a similar variant.
Canteen - for water. Confederate manufacturers produced tin and wooden canteens. Wooden canteens are generally described as Gardner or Nuckolls patterns. CS tin canteens may be "tin drum" type, or copies of the US M1858 "smoothside canteen". Patent filter canteens would have also been available, generally as a private purchase item.
Cartridge box - for carrying ammunition. 1862 is generally viewed as too early for large amounts of imported accouterments. Primarily soldiers were carrying CS copies of M1839 or M1857 cartridge boxes, or their captured Federal counterparts. CS manufactured cartridge boxes have many specific features that distinguish them from US varieties, but generally follow established pre-war Federal patterns, as with many CS equipments. The box may or may not be worn with a box sling.
Cap pouch - for carrying percussion caps. Provided the soldier was not carrying a flintlock arm, a percussion cap pouch was worn on the right front of the wearers belt. Again, CS manufactured pouches generally follow US patterns. The M1845 and M1850 patterns are common CS copies, as are "shield front" cap pouches. Again, captured Federal accouterments may be encountered.
Bayonet scabbard - for carrying the bayonet. Scabbard is worn on the left side of the wearers belt. CS bayonet scabbards are typically fully sewn versions of the M1859 scabbard. Sometimes encountered with brass, or tin tips, or as in the case with some scabbards issued through Richmond, with a fully sewn tip. Again, captured Federal accouterments could be encountered.
Waistbelt - for carrying the cap pouch and bayonet scabbard. As mentioned, the other accouterments are worn on this belt. Some cartridge boxes are designed for belt carry only as well. If a soldier did not have a box sling for his cartridge box, it would have been carried on the belt. Belts were simple leather affairs. Although some oil, or tarred cloth versions are encountered. Belts were secured with a variety of closures, the most common of which were: roller buckles, frame buckles and stamped CS "egg" plates. Some state belts were also worn, along with plain sheet brass and tin belt plates.
Knapsack - a backpack, for carrying a blanket, ground cloth, tentage, personal items. It is important to note that not all Confederate soldiers were issued knapsacks. However, CS domestic production are generally copies of the US M1825 "Mexian War" knapsack. Militia "hardpack" style knapsacks would also still be encountered at this time. There is a series of images taken of CS dead at Sharpsburg that show Confederate soldiers with French style hardpack knapsacks. There is also evidence that apart from some limited importation that there was some attempt to domestically produce French style knapsacks. Federal knapsacks are of the M1855 type, or contractor variants, and may have been used.
Inside the knapsack soldiers would carry a blanket and groundcloth. CS groundcloths are painted cloth, where as Federal versions are rubberized cloth (however, painted cloth Federal ground cloths were common; as there was a shortage of rubberized ground cloths). A Confederate soldier might also carry a civilian floor cloth. If he did not have a knapsack, the ground cloth, blanket and any personal items would be rolled into a bed roll and carried as a horse collar, or hobo roll.
Confederate tentage is an interesting subject. Generally CS troops, if they received anything, were issued rain flies that 6-8 men could sleep under. Recently, the subject of CS produced shelter halves has been approached, and good evidence to some large scale production of them has been uncovered. However, CS production of shelter halves was not nearly as prevalent as US production. Again, captured Federal stocks could make up deficiencies; however, most deliveries for US shelter halves don't start until 1862, so, depending on the time, they might not have been all too common in US ranks either.
Arms were a large mix during this time. Depending on the unit a soldier may have carried anything from percussion altered Swan contract Revolutionary war muskets and civilian rifles to brand new P1853 Enfields or captured M1861 Springfields. Each arm would, in theory, come equipped with a bayonet, sling, and appropriate cleaning tools including a cone wrench/screw driver, wiper and ball puller.
A soldier would have worn a shirt, drawers, socks, trousers, jacket, cap or hat, and shoes/boots. As mentioned previously depending on the exact unit the soldier may have received some or all of his clothing from a government depot. Some soldiers received State issued uniforms, North Carolina, Georgia, and Alabama, come to mind. Local clothing drives were also made for some out of state units, and depots were set up to store these goods, e.g. the Texas Depot for the Texas Brigade.
Imported accouterments, weapons, and clothing is a very interesting topic as well. Although I think that most would agree with me in that the majority of military goods received up through 1862 were arms deliveries.
Hope this answered some of your questions,
