I believe (from recollections of reading perhaps dodgy books a very long time ago) that when the state of Cuba was under the pre-Castro regime, the US Govt paid a normal mutually agreed annual fee for the use of the American base on Cuba. However, post-1959, Castro refused to accept the fee, which was fine by the Americans. Is this more or less true?
Also, and not really connected with this, were USAAF B-29s squadrons located on Cuba in 1944, working up to operational status prior to deployment to the North Pacific? I presume this would have been same airfield, or was it another?
