for me it was the bravery these men had in them to go to combat in there
iron coffins.
i have been on 2 museum pieces here in my area where i live.
american ww2 boat uss ling ,and later dated cold war boat uss growler
am 6 foot 5, i was having a hard time venturing through the boats.
i said no way i could do this, fight and live on it.
also the upmost fear of being depth charged imagine the noise fear sweat
cold sea water pouring in.
no escape if the boat did not surface.
