Aye, a good thread and one that brings home realities of combat equipment and environment.
I used to take part in late C15th re-enactment some years ago. The largest annual UK medieval re-enactment was and I believe still is Tewksbury.
This was a great adventure to partake in and could also be a fair test of fitness and endurance given the conditions.
A couple of years saw it in sweltering heat, which saw many dropping like flies with heat exhaustion and/or blacking out. I threw up myself once in full kit, but to be fair, the combination of a hard battle under hard conditions after a hard night in the beer tent lead to my momentary tactical retreat.
One year, I remember one fellow in a pig face bascinet -
Conditions - Decidedly wet underfoot following rain during the night and morning.
Situation - He falls face down with one or two others on top of him.
Result - His pig face stuck firmly in the mud, water rapidly filled in through the vent holes and he nearly drowned in a few inches of muddy puddlewater.
These served as stark reminders that it wasn`t all just about going out there and having a jolly good time, but that all eventualities had to be accounted for given the effects of armour in various atmospheric conditions.
