My Time Traveller’s Guide to Medieval England says “…you would be crazy to think you could engage a 14th century man in combat and have a chance of surviving. Most of them are much stronger than you.”
So let’s say you have to square off against a medieval peasant - or villein, more correctly. He’s from 1305 - before the Great Mortality and Great Famine, but poor diet combined with health and hygiene mean he stands at about 5ft 7, weighting in at around 136lbs. He’s 21 - the median age of the population. He’ll probably die between the age of 40 to 50, if he’s lucky.
He wears a calf-length tunic over undertunic, hood and rough leather boots. Mostly he toils on the fields on his lord’s estate, a hard and physically demanding life but his leisure activities include cock-fighting, watching bull-baiting, beating the crap out his wife and the odd bit of wrestling. Unlike a knight he has no formal combat training or weaponry. His lord has ordered that you must die (say you’ve travelled back in time and annoyed him with your ideas of egalitarianism or something) and our serf is charged with the task. It will win him his freedom and a hefty stipend from his lord, so you won’t talk him out of it.
Based on your height, weight, unarmed combat experience, martial arts knowledge how fucked are you (you can dress how you want, but don’t have any weapons either)?
How do you go about defending yourself when this rustic-smelling villein sets about your person?
