I can find the total sunk over the whole war in the Atlantic (around 14M), and wikipedia/other sites show total sunk for example off the US East coast as around 3M but I cannot find information on the other areas such as the mid/south Atlantic or the 'Cape Farewell' route past Iceland.

Not sure where I would look, as none of the books I own about the Battle of the Atlantic have this information in easily accecable table format so any help would be appreciated!
