As a result of French representations (Dominions Office D.37) [1]
action against Narvik shipments further examined by War Cabinet
today and proposal for laying mine fields in Norwegian territorial
waters considered.

In my view there is an absence of clear thinking as to objectives
and consequences of contemplated action.

I have accordingly urged United Kingdom Government that it is
unreasonable to ask for concurrence of Dominions in action which
might have the most far-reaching consequences unless they have
been fully informed of grounds which led to decision, of possible
consequences that may result, and of steps that could be taken to
meet them.

Endeavouring to arrange meeting tomorrow with Prime Minister [2]
and Halifax. [3] I am hopeful that as a result of such meeting
full information down the lines indicated above will be cabled for
your comment before final decision taken by War Cabinet. [4]
