Churchill's Exploding Rat

[TDH]

Regarding the film The Guns of Naverone, I believe that the idea of leaving the rat bomb and other explosives on the guns and carriage, in obvious positions that were easy to spot, was in order to give the Germans "something to find". The actual explosive device that did the damage was hidden on the elevator rails which led down to the magazines for the shells and charges if separate to the shells.

We used the same philosophy when I was building structural steel. When the inspector came in to go over the beams and columns we always left one or two small flaws that didn't matter they could find. That seemed to make them happy that we weren't polished to perfection. I asked about it one day when my foreman (Guadalcanal vet/ first wave) told me not to polish that small flaw and why. It worked.
