How do you find out the undisclosed recipient?

You can not actually get them - the information is not sent with the email You can try replying all and ask for a "confirm on receipt" reply. You may be lucky and get the receipts but it depends on how the mailing list has been set up.

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.
