Sir, I think I have communicated with you before about Camp Nelson. However, my great grandfather was there in 1862 in December when everyone including himself was sick. I have an original letter that he wrote to his parents and sister describing all the illnesses and also the death of his sister's husband Joseph Pendergrass.He lists all the ones from his home town that have died. He describes the weather and conditions of camp and some of the plans of the unit.His name was Corp. John Harmon Carter and I would be glad to share it with you. He was in the 22nd.Texas Infantry (Hubbards Regiment). There is a site on Face Book called " The 22nd. Infantry" and I have a copy of the letter published there. Mary Braneff
