Not WWII I know, but…
My father was in the 7th Marines Division at Chosin Reservoir Noth Korea -the bloodiest battle in the history of modern warfare. 240,000 Chinese attacked 27,000 UN troops, mostly fighting the tiny force of 7,000 USMC that were at the front. The Chinese tossed bagfuls of hand grenades and used cheap sub machineguns. Most of the Marines used an M1 Carbine, some had Thompsons, a few had Garands. The kill ratio was 10-1 in favor of the US Marine Corps. The temperature was -40 F and medics were putting ampules of morphine in their mouths to thaw them for injection into the wounded. Dead Chinese soldiers were frozen stiff and pulled up to the edge of the foxholes by US marines to use their rock hard bodies as additional cover from the massive onslaught. The fighting was very close, mostly 200 yards or less as waves of Chinese soldiers ran over a hill at the small American force. If ever there was hell on earth, it was there and then.
Obviously, he survived, for I am here writing this. : )
