Well i think the title say's all but here some necessary details to make some focus:
I would like to know if there's a record of a Battle or a Siege (or War, but only optional) which have been decided due to an epidemic plague: most soldiers, warrior got at least a grave disease?
decided: Ended, either both sides "resigned" or one side could win because the other couldn't really fight!
Focus
- As Time Period i would like to take the middle-ages, more exactly 8th-15th Century!
- Also i would like to emphasize on battles in which the fighting parties had different ethnic groups!
This is just a Question that came to my mind and as i myself have no idea how many battles could have this special ending i'd say:
This is explicitly an list question, so feel free to provide list answers.
But i'm still open for helpful comments and further inquiries to make the Question more focused!
I only know about a malaria epidemic which weakened the Ottomans during the siege of Belgrade 1717.
