I know of a source for hardtack and similar items. You can order online as well. The name of the company is G.H. Bent Co. Actually have a couple of boxes of their hardtack.
Quoting from the side of the box:
"We here at Bent & Co., makers of the original hardtack of the civil war, would very much like for you to try our hardtack. Just as your bullets are blanks so as to cause less pain in re-enacting the battles and skirmishes, so your Bent hardtack is packaged fresh in resealable plastic so as to cause you less pain when re-enacting the supper. Because of the freshness of the cracker it can be eaten as is or prepared in any number of ways according to your taste and ingenuity. We hear of a dish called "skillygalee" in which the cracker is soaked in water and fried brown in pork fat, salting to taste. Though Julia Child may not serve this dish, neither would she go through the considerable trouble of dressing up in 1860's clothing and fight in the hot sun for a hill top. The finer things in life must be gotten at some risk."
Quoting from another side of the box:
"If you hold the spirit of authenticity dear, no other cracker will do. You have gone to considerable trouble to outfit yourself with all the proper attire and equipment, why not complete the outfit with the original hardtack?
It is the dying wail of starving, Hard crackers, hard cracker, come again once more, You were old and very wormy, but we pass your failing o'er, O hard crackers, come again once more.
The Bent hardtack cracker is still baked today by the Bent Company in Milton, MA. Bent Company was an original purveyor of hardtack to the Union Army."
