Cablegram E95 WASHINGTON, 18 May 1943, 12.30 a.m.
Reference Bruce's telegram S.57 repeated to Washington. 
I think Bruce's contact with the Polish Ambassador quite
unnecessary. Bruce was informed by me of the matter and the
procedure to be adopted; namely a clear indication that no action
was necessary in London.  He knew that the Prime Minister has
authorized me to deal with Churchill.  The United Kingdom was
acting for the Commonwealth in duly obtaining the Polish
Government's consent. There the matter ended in London. Bruce's
intervention increases the risk of premature disclosure and
consequent embarrassment. Bruce is not our Minister to the Polish
Government. For instance, it would be inappropriate for formal
letter referred to in S.99 to go through Bruce when United Kingdom
acting for us.
You will agree to this point of view. Please watch Bruce's cables
closely in order to keep me informed of any others of similar
nature. This, coming on top of his asking for Officer be appointed
Minister , confirms the suspicion that the two have been in
communication on the matter without reference to you or me. Having
reference to the previous conduct of Officer , wish you to be
on your guard throughout all these negotiations.
