Thus, I stand by the only known genocidal use of a WMD as being Smallpox in U.S. vs. Native Americans in the Mid-1800's, and again am humble in this declaration, hoping that someone more informed than I can suggest a correction to this assertion.

Can you please reference this? If Wiki is right, you've got the wrong century, the wrong protagonist (the U.S.), and it's an unproven allegation, not fact.
wiki Biological warfare says:

There is, however, only one documented case of alleged germ warfare, involving British commander Lord Jeffrey Amherst and a Swiss officer, Henry Bouquet, whose correspondence included a reference to the idea of giving smallpox-infected blankets to Indians near Fort Pitt during the French and Indian War (1756-1763). Historians have been unable to establish whether or not this plan was implemented, particularly in light of the fact that smallpox was already present in the region. ... Despite the lack of historical evidence, the claim that British and American soldiers used germ warfare against North American tribes has remained fairly strong in certain oral traditions and in popular culture.

So, it is not known if the idea was implemented in the mid 1700s, and if it was, it is not known if it had it's intended effect since the disease was already in the region for quite a while. The story of the pilgrims suggest a plague (probably smallpox) preceded their arrival. There's nothing from the mid 1800s attributed to the U.S. as you suggest.
