The Belgian resistance during WWI was not a single organization but a collection of about 300 informal groups. These networks, often led by aristocrats like Prince Reginald de Croix, focused on intelligence, underground newspapers, and smuggling Allied soldiers rather than widespread sabotage.

Cavill openly confessed her role in helping almost 200 Allied soldiers and civilians escape. This unusual honesty, potentially stemming from her pious Christian faith or naivety, meant she effectively condemned herself, making no effort to deny the charges that led to her execution.

The resistance network's downfall came from Georges Gaston Quillon, a criminal who posed as a French fugitive officer. He successfully fooled the network's leaders, including Cavill, gathered intelligence for two weeks inside her clinic, and reported back to his German handlers, leading to mass arrests.

Intelligence agencies' biggest concern is "blowback"—the severe diplomatic, economic, and intelligence-sharing penalties from allies if a covert operation is exposed. The risk of alienating a critical ally, such as the U.S., far outweighs any potential gain from an operation like a political assassination on their soil.

The execution of a nurse, regardless of its legal justification, provided a powerful symbol for Allied propaganda. It was framed as an act of barbarism, galvanizing anti-German sentiment in Britain and neutral nations like the United States, far outweighing any military benefit of stopping her network.

Contrary to the propaganda narrative of a lawless murder, Cavill was tried under Section 58 of the German military code. Her actions, including helping able-bodied men join Allied armies, clearly constituted "war treason," for which death was the prescribed and explicit penalty for foreigners.

Far from being just a guerilla force, the Polish Home Army operated a sophisticated underground state under Nazi occupation. This parallel society included its own law courts, a clandestine university, and printing presses, demonstrating an unparalleled level of organized civil and military resistance.

Demonstrating the enduring power of her story, when Hitler visited occupied Paris in 1940, he specifically ordered the destruction of two monuments. One was for a French general, and the other was for Edith Cavill, revealing how deeply her martyrdom narrative resonated as an insult to German national pride.

The frustrating techniques common in modern customer service—creating needless complexity and slowing down processes—are nearly identical to the "simple sabotage" tactics promoted by the US government for citizens in Nazi-occupied Europe to disrupt enemy operations.
