How did the disease trench foot have impact on the war effort?

Answer 1

Some say that an Army marches on its stomach. Some say that your

most important tool in combat is your rifle or that wars are won by the

threat of the bayonet. All true, but trench foot and frostbite have had

a debilitating effect on troops since they began marching into combat.

Modern warfare may not be as dependent on boots on the ground as

it once was, but, the health of the troop's feet can be costly. They once

said something about "for want of the nail, the shoe was lost, for want

of the shoe the horse was lost, for want of the horse the battle was lost

and for want of the battle the war was lost". We don't use horses much

in today's warfare, but the concept is the same.
