I see these illustrations of massive armies fighting on sunlight days in arid or humid Mediterranean climates. Anybody who has been through the rigors of summer football practices, been in a physical fight with adrenaline pumping, etc. knows you can’t keep a sustained fight or flight response going for long.

My question: What did these soldiers do for water, the only thing that would sustain them for long? I recall Bloody Pond at Shiloh where the wounded crawled to drink from the pond and turned it the color of blood.
