German intelligence issues assesment of Fighter Command's control system

German intelligence circulates its appreciation of Fighter Command's control system to operational commands.

As the British fighters are controlled on the ground by R/T, the forces are tied to their respective ground stations and thereby restricted in ability, even taking into concideration the probability that the Crown stations are partly mobile. Consequently, the assembley of strong fighter forces at seven points and at short notice is not to be expected. A mass German attack on a target area can therefore count on the same conditions of light figher opposition as in attacks on widely scattered targets. It can, indeed, be assumed that considerable confusion in the defensive networks will be unavoidable during mass attacks, and that the effectiveness of the defences can thereby be reduced.

Not sure what "Crown stations" are.
