IIN, the case of medieval bio warfare?

Bubanoic Plague, Small Pox, Malaria and TB are are four of the deadliest diseases that have caused some of the deadliest epidemics in the last millennium. Yes there are countless instances when small pox was used as a bio weapon. 90% Native American population are said to have been killed by the small pox when Europeans invaded them and used the disease as weapon against them, (in numerical figures thats over a 100 million people) another extreme example of medieval biowarfare. A confirmed incident is the s "Siege of Fort Pitt" in 1763 during the Pontiac's War. It is alleged that small pox virus was even used as a bio weapon in the two world wars , the death toll in the 20th century alone was 500 million from small pox. There are also report that armies would trap and shoot infected people during war times to prevent them from spreading the disease, as the small pox virus was very contagious and could easily spread. Thankfully the small pox vaccine was discovered and mass vaccination campaign started, and bio weapon had been banned after establishment of the UN. In 1979 the world was said to have totally eradicated one of the deadliest disease known to mankind, small pox. Ive seen some images of small pox infected people, very graphic and tragic a human body had to go through these before dying a painful death. Today the world is finally free of small pox with the rapid advancement in medicinal science. Let us hope that this continues and slowly we end all the deadly epidemics that still exists and totally eradicate the deadliest diseases there is, as we have done with small pox.

I think that was what I was trying to say.

Small pox and Bubanoic Plague were both used along with other diseases too. But the 14th Century Great Plague saw by far the deadliest use of biowarfare led mainly by the Mongols but later adapted by others, it wiped out 60% of the then European Population, sometimes it came along with invader migration and seeing the effectiveness the invaders catapulted and threw dead bodies of infected people into enemy territories and the highly infectious disease with no cure than wiped out entire populations there. The period 13th-14th Century is notoriously known as the Dark Age mainly because of the Great Bubanoic Plague epidemic also called the black death, arguably the worst disease epidemic in history which killed 200 million people in Europe, Asia and Africa out odf a total worl=d population of 450 million then, human population has never experienced such decline since the end of the epidemic. The disease was mainly caused by rat bites, but it was spread in such a a large scale when it was used as a weapon of war. Thankfully today bio warfare is banned, listed as a WMD, use of which is a war crime. And the bubanoic plague today has a vaccine and is easily curable, but it has yet to be totally eradicated like small pox has been (1979), but hopefully will soon...

Not really. Humans kill humans. What do you think Aztecs, Mayas and Incans did to their enemies? Do you know why I said it's speculation? Because they didn't know how could this be done. And at the end the English, Portuguese, French... ended up being worse for the native peoples of America.
