Hah, is that even physically possible? As in, is there enough surface area on the human body for 6584 arrows to hit?
A great many of them probably just split other arrows already hit.
Now, if we assume that each arrow weighs about 4 ounces, that's 1,646 pounds worth of arrow embedded into the body of this one person. That's not so much a hedgehog as a hedge with potentially a hog somewhere inside. I like to imagine that the peasant in question literally kept charging until the weight of accumulated arrows crushed him, because there was no other way, he kept on coming.
