There is a plan on foot for the British to charter these Norwegian ships and to arm them, taking the risk of German war against Norway.

If war comes (as it is expected) England must then defend Norway the best she can.

All this is yet in the future, but possibly not far in the future.
For the present the only anti-submarine help is the help we may be able to give to patrol the wide area off Ireland.
