11th May, 1940
Dear Sir Walter,
Thank you very much for your letter WMC/WJB/DT/892 of the 2nd May about the cases of Largo Caballero's son and Rafael Henche, ex-Mayor of Madrid.
Our attention had already been drawn to the case of Senor Henche and we recently instructed our Ambassador at Madrid to take any action that may be open to him on Senor Henche's behalf.
We have now sent similar instructions to Sir Maurice Peterson to do what he can in the case of Senor Caballero' son.
Sir Walter Citrine, K.B.E.
