Read the story here: “The combination of moderate temperatures, a pleasant breeze and
overcast skies made for the perfect environment for a battle, at least
from the re-enactors viewpoint, since it minimized the chances of
succumbing during the battle to heat-related problems. Excessive heat and humidity can drain the energy level and exuberance of the re-enactors and affect the animals as well.”
Yes, I’ve heard that this can be an issue for reenactors who strive for authenticity.
