Minute by WSC [First Lord of the Admiralty] stating that it was much harder for the Royal Navy to stop raids or invasion from Germany than it was 15 years earlier from France, due to the superior defences and number of naval bases on the south coast; WSC stresses the inadequacy of the east coast defences, particularly compared with the natural defensive and military strength of the German North Sea and Baltic coasts; also the difficulty of keeping a close watch on the German naval exits and the possibilities of invasion.
