How many German U-Boats were used in World War II?

Oh god there were about 1500 U boats made during world war 2 and guess what not even 25 remain from the war today,All of them were either,scuttled,sunk,mined,grounded,or captured. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
