Hello Alex,
I have looked at quite a few Web sources, their problem is that they are incomplete and contradictory. Furthermore, nothing on the Web addresses the subject of Luftwaffe ship sinkings directly. For example, the page on uboat.net -
http://www.uboat.net/allies/warships/war_losses.html - simply lists all losses known to the authors and makes an attempt to note the cause of each loss in the broadest outline. Therefore, it's not very good for the specific subject in question. Having said that, I concede that it has some good material on Allied submarines, as reflected in the list of updates -
http://www.uboat.net/allies/warships...t_updates.html
I understand that my query is broad and therefore finding the relevant infromation is difficult. Do you know of a source or sources for specific campaigns, for example the Mediterranean in 1941?
Regards,
Paul
