I worked with an old guy who had been a medic at the battle of the bulge. He told me several of the wounded survived because their wounds froze and stopped the bleeding. That image has stuck with me for fifty years. Imagine the cold and the suffering.
One of my old Sunday school teachers got wounded pretty badly during the Bulge, was aboard an evac ship on the way to England, minding its own business, but the Germans sank it (not sure how, maybe it was a passive sinking via a mine). He survived this, I think all or most of the crew and patients managed to get rescued, but WTH man. I’ll try to get the details straightened out.
