For the Chief of the Naval Staff  from Naval Attache. 
Tropic  3.
Report of conversations book 2, appendix 7, paragraph I I and B.U.S. (J) (41) fourth meeting , paragraph (2). Admiral Danckwerts  has now returned from his visit to Commander-in- Chief of the United States Pacific Fleet. 
(2) He reports that in the opinion of the Commander-in-Chief and his staff, direct operations against Japan by Naval or Naval Air Forces are not a practical proposition partly because the risk to forces engaged, both from enemy attack and from difficulties of refuelling, are not the ones they are prepared to accept, and partly because they hold theoretically that unless continuously repeated such raids are not of value.
(3) They are considering operations against Japanese bases in Marshall and Caroline Islands as a kind of step by step offensive South West but no definite plans to this end appear to be in existence nor do they appear to be in possession of detailed knowledge of Japanese defences and preparations there nor necessary means of overcoming Japanese shore resistance.
(4) They are not in favour of operations conducted in Aleutian Islands on account of bad weather in that neighbourhood and distance from Pearl Harbour but they are shortly sending a force to cruise in that neighbourhood as a supplementary gesture to recent cruise of their ships to Australia and New Zealand.
(5) In general they hold to a hope that mere existence of United States Pacific fleet based at Hawaii will produce a containing effect on Japanese naval forces but Admiral Danckwerts does not consider we can count upon any active demonstrations in Japanese waters.
(6) Admiral Danckwerts emphasised the need for diverting Japanese strength to northward and he is confident that Commander-in-Chief of United States Pacific Fleet will reinvestigate every possibility that can be suggested for more active operations calculated to have greater containing effect on Japanese naval forces.
(7) Admiral Danckwerts' telegraphed report to United Kingdom of which foregoing is a summary has been repeated to Commander-in- Chief, Far East.
