Hi John!

We have just recently, a week ago,discussed losses in the Battle of Atlantic
on this Forum,in the GENERAL Discussion Forum!

If You please go there,and do a SEARCH on the thread:
"UK strangle:Facts or Fiction",than You will find in my first 2 postings
some statistics over human losses of lives in that battle.
Start the Search by simply printing " UK " in the search window.

I do not know where one can find compiled statistics of
Allied lives lost on Allied Merchant ships sunk by UBOATS specefically;
but I hope some of the general statistics in that thread,will be of some help for You!

Best regards/Anders.
