Although I can't give you an exact number, there are several (identified) Confederate burials sprinkled throughout the various older cemeteries in and around Iuka. From my own research, I've found a handful of men so buried who were wounded in the fight at Iuka, and yet survived long enough to escape the mass grave, but were later buried by those area families who'd cared for them in the battle's aftermath. My guess would be that similar individual acts happened to and for those wounded men sent to Iuka (then in Union hands) from the battlefield at Corinth (Oct 3-5, 1862). [By the way, the "DeWoody" list that's been quoted for Iuka casualties is more accurately a list of "known Confederate burials at Iuka," many of which predate the Sep 1862 battle by several months, but fortunately for us, Mr. DeWoody DID record those names as his list is a definitive source for several dozen period burials of men who died in hospital or private homes there that are now unmarked.]

I'd recommend contacting the Tishomingo County (Miss.) Historical Society at Iuka <http://www.rootsweb.ancestry.com/~mstchgs/> for any potential lists or insight they may have as to where any hospital-functioning structures may have been. I believe there are a couple of local area historians from there who've documented these marked graves in one way or another. It'd take some cross-referencing work to figure if they were Corinth casualties. It also appears that there are a good many unmarked, yet individual, Confederate graves throughout that county which are also tied to the Corinth battle(s).

Wish I could be of more help. Good luck!
