Englandspiel, or “how not to conduct clandestine operations”

Wikipedia has a good summary

>**Englandspiel** (‘England Game’), or **Operation North Pole** ([German](https://en.wikipedia.org/wiki/German_language): *Unternehmen Nordpol*), was a successful [counterintelligence](https://en.wikipedia.org/wiki/Counterintelligence) operation of the [*Abwehr*](https://en.wikipedia.org/wiki/Abwehr) (German military intelligence) from 1942 to 1944 during [World War II](https://en.wikipedia.org/wiki/World_War_II). German counter-intelligence operatives, headed by [Hermann Giskes](https://en.wikipedia.org/wiki/Hermann_Giskes) of the [Abwehr](https://en.wikipedia.org/wiki/Abwehr) and Joseph Schreider of the [Sicherheitsdienst](https://en.wikipedia.org/wiki/Sicherheitsdienst) (SD), captured [Allied](https://en.wikipedia.org/wiki/Allies_of_World_War_II) resistance agents operating in the [Netherlands](https://en.wikipedia.org/wiki/Netherlands) and used the agents’ radios and codes to dupe the [United Kingdom](https://en.wikipedia.org/wiki/United_Kingdom)’s clandestine organization, the [Special Operations Executive](https://en.wikipedia.org/wiki/Special_Operations_Executive) (SOE), into continuing to infiltrate agents, weapons, and supplies into the Netherlands. The Germans captured nearly all the agents and weapons sent by the United Kingdom (Britain). Englandspiel was a “catastrophe” for SOE and the [Dutch resistance](https://en.wikipedia.org/wiki/Dutch_resistance), “a textbook illustration, the world over, in how not to conduct clandestine work.” Fifty-four SOE agents sent from England were captured by the Germans and only four survived.

Honestly thought the meme would be about the Venlo Incident but yea, Brits had a hell of a time in the Netherlands during the war
