I wish I had my set with me, but this is an interesting bit from one of the appendices of Churchill’s illuminating History. Note Churchill’s attitude with regards to invasion possibilities is not only heavily sarcastic, but completely focused on the logistics:
My favourite example appears in Appendix C to Volume III, The Grand Alliance, where Churchill responds to General Brooke’s report on an invasion exercise called VICTOR, which presupposed that the Germans landed five divisions on the Norfolk coast and established a beachhead within forty-eight hours. Churchill writes:“I presume the details of this remarkable feat have been worked out by the Staff concerned. Let me see them. For instance, how many ships and transports carried these five Divisions? How many Armoured vehicles did they comprise? How many motor lorries, how many guns, how much ammunition, how many men, how many tons of stores, how far did they advance in the first forty-eight hours, how many men and vehicles were assumed to have landed in the first twelve hours, what percentage of loss were they debited with? What happened to the transports and store-ships while the first forty-eight hours of fighting were going on? Had they completed emptying their cargoes, or were they still lying in shore off the point protected by superior enemy daylight Fighter formations? How many Fighter airplanes did the enemy have to employ, if so, to cover the landing places?…I should be very glad if the same officers would work out a scheme for our landing an exactly similar force on the French coast at the same extreme range of our Fighter protection and assuming that the Germans have naval superiority in the Channel….”
