My pardon if I wasn't clear, I was speaking of the troop and supply ships being annihilated.
I'm aware of that, but given the right conditions, such as, say, a freak bomb kills McAuliffe, throwing the command structure into disarray, a few more days of bad weather, a German spoiling attack against 3rd Army preventing Patton's relief operation, or any number of other factors, this could have turned into the biggest mass surrender of the war.
Not saying it's likely, just that given the right POD, it seems as if it would be possible.
