Its a start. If I pursue this far enough the sources can be investigated. In the mean time I can make some checks of the gross numbers against Ellis 'Brute Force' or Hughes & Costello 'The Battle of the Atlantic'. Both have quarterly totals.

That is not made clear in the other books I've looked at. Was the mine laid by submarine. aircraft, or surface ship???

I also find the air attacks figures for late war strange: 7176 tons sunk by air attack in May 1945 ? This figure is corresponding to one Liberty Ship but it seems to me that by this date the Luftwaffe was no more active against Allied ships.

A a wild guess this may have been in the North Sea, perhaps on the approach to Antwerp. There were still a few aircraft operational in Norway & Denmark in May as well.

I notice that in April 1941 the losses to aircraft are larger than to submarine. If accurate this is interesting as the submarine losses are not trivial.
