A strident effort has been made by German propaganda to persuade the world that we have laid these magnetic mines ourselves in the fairways of our own harbours in order, apparently, to starve ourselves out. When this inanity expired amid general derision, the alternative claim was made that the sinking of the neutrals by mine was another triumph of German science and seamanship, and should convince all nations that the German mastery of the seas was complete.
1939, 6 December.
The magnetic mine, and all the other mines with which the narrow waters, the approaches to this Island, are strewn, do not present us with any problem which we deem insoluble. It must be remembered that in the last war we suffered very grievous losses from mines, and that at the climax more than six hundred British vessels were engaged solely upon the task of minesweeping. We must remember that. We must always be expecting some bad things from Germany, but I will venture to say that it is with growing confidence that we await the further developments or variants of their attack.

(Blood, 250.)
I feel entitled to say that we see our way to mastering this magnetic mine and other variants of the same idea. How this has been achieved is a detective story written in a language of its own. Magnetism is a very exact science, and its complications and refinements can all be explored and measured. To be modest, we do not feel at all outdone in science in this country by the Nazis.
