7175. Your 9399. Department does not deem it advisable to begin the operation of Q boats on this side of the Atlantic.
(First) In the operations this far conducted by U151 considerable precaution has been taken to safeguard life, the result has been very few casualties. The military value with ships sunk has been very small.
(Second) The success of Q boats would be entirely in the initial stages, later their value as taken from your own report would be very small and their use would be met by reprisal in some form. The great danger of reprisal lies in its effect on the public mind and the pressure it might bring to bear to hold force here which should be dispatched abroad.
(Third) Department feels that in a short time through its routing and arming of ships and with the proper distribution of its available forces it will have the situation well in hand without materially decreasing its out put across Atlantic. 19012 7175.
