Cablegram 280 LONDON, 4 June 1941, 12.35 a.m.
MOST SECRET
My telegram No. 237 of 17th May. [1] Please inform the Prime
Minister [2] that, in accordance with the recommendations of the
Washington Staff Conversations, we have now established a nucleus
military mission in Washington and that a nucleus United States
military mission is being established in London.
2. The object of establishing these missions now is to ensure that
the necessary machinery of collaboration is ready whenever the
United States may come into the war and that all details are
completed in respect of the broad plans agreed in Washington.
3. Admiral Sir Charles Little, Lt.-General H. B. C. Wemyss and Air
Marshal A. T. Harris will take up their appointments as heads of
the mission representing the chiefs of staff of the United Kingdom
about the middle of this month. Meanwhile other officers are
representing them and the mission is in operation.
4. It is assumed that in accordance with annex 1 para. 5 (f) of
the report on the conversations (A.B.C.1) [3] the Commonwealth
Government will wish to be represented on the mission in
Washington by their service attaches and that they will issue
instructions accordingly. [4]
5. Neither our mission in Washington nor the United States mission
in London can be recognized openly as staff missions until the
United States come into the war. Both missions therefore are
operating under cover, the former as 'necessary advisers of the
British Supply Council in North America' and the latter as 'the
United States Special Observer Group'.
