As always, translations are full of dangers, but they seem to imply that stockings (stockings at this time in history) have been worn to the knees.
Many oil paintings depict men engaged in manual labor. Underwear is usually tied to tights, but in hot weather or hard work, it can be untied and pushed to the knees to form a sock-like shape. Needless to say, this helps the blood circulation around the thighs.
Please note that in the first photo, the man also took off his shirt and put his coat around his waist. In the background, you can see people wearing the same stockings, but they are tied to tights, not worn out. Also note that they are all wearing linen underwear.
As you can imagine, this device can let some air cool the private parts, unlike you wearing real underwear on your knees, you can run and beat like this. As can be seen from the above, people who do heavy work adopt this kind of clothing. Frankly speaking, it seems to cool you more than modern shorts. In a hurry, it also allows real underwear to be easily obtained.
Now there is some debate about how many people in Yinxing Town suffer from dysentery.
But what is certain is that Haverle's seafood feast makes many people sick. After the fall of the city, some patients returned to England because of illness, while others crossed the land to Calais.
This is where historians differ on this issue. Some people think that almost all the people who are too sick are left behind, only those who are healthy enough to continue, while others think that only those who are seriously ill and injured are brought back. A British chronicler who didn't attend simply said that many people were influenced by Dynsentry. Modern historian Anne? Anne Curry studied some evidence, such as the patient list, and came to the conclusion that almost all the people who fell ill in Haverle were sent back to England.
Maybe most of Ginkul's troops got dysentery, maybe only a few people got it. We can never be sure.
I think it is more interesting to think about whether the struggle of sewer pipe is really related to dysentery. As you can see from the above picture, it is simply "farmer's clothes" for lack of a better word.
If Americans in Europe have food poisoning, some people will notice that many Americans in Europe are wearing ugly work clothes, but this does not mean that Americans wear work clothes, because they are always taking a shit.
Sources mentioned that Ginkul's archers wore knee-length stockings, and in the same sentence, they were considered to have no armor or only axes and mallets. In other words, they are wearing workers' clothes.
I don't see any connection between the clothes of archers described as typical working men and their dysentery. This is established by modern historians, who may not know the typical clothes of 15 th century.
I hope someone can prove me wrong, and they can establish a better connection, because it seems to be a good story, but from what I have read, I have not seen a good case.
