To this day, there is no exact count of how many men died on D-Day. It was such a chaotic bloodbath that it was impossible to even attempt to make accurate records until days later, when more men had died and gone missing and been wounded in further combat actions.
Not to denigrate the men but it is pretty hard to run to the rear in an LST...
I talked to a WWII vet who said he was told the same thing, and in the innocence of indestructible youth, he and the others looked at each other and said "You poor bastard".
[sidebar] I'm reading "D-Day" by Stephen Ambrose (again) this week and decided to fly the flag today.
