Jim,
Thank you for that link. I like you don't think that there is any evidence of willful attempts to wipe out the Indians at that time or to make germ warfare on anyone during the War Between the States. As we know, medical science was ignorant in terms of germs of any sort at that time. We see that in the number of men on both sides who died from infection. Most of it from lack of sanitation in the field hospitals and aid stations of the time.
