Could the closed Greek helmet kill a warrior?

Lets say you had 50’000 men out fighting a the enemy another army of 50’000 men – how many would lay on the battlefield with a heat stroke if the temperature was from 35 to 45 C within the first six hours?[/QUOTE]

Hi Guys

The history channel has a show called battlefield detectives and on one episode the talked about the battle of monmouth in my home town during the American revolution. I seems large numbers of British troops died from heat stroke due to their heavy wool uniforms and carrying heavy gear and lack of water. The Greeks wore very little clothes a tunic light body armor such as a breast plate shin guards and arm bands along with the helmet. I'm sure their were some number of warriors who died of heat stroke but that type of armor was worn by many armies over hundreds of years so if there was a big problem with men dying of heat stroke then why was that type of armor so popular and used for so long a time? I have read that celtic warriors fought completely nude with no armor that must have kept them cool but it is not a good idea to be running into battle with certain extremeties exposed when there are sharp swords being waved around you could end up singing a few octaves higher at the end of the day
