WHY IT SEEMED IMPOSSIBLE

Rotor motion changed the substitution at every press. Rotor order, positions, rings, reflector and up to ten plugboard pairs multiplied the possible settings.

WHY IT WAS BROKEN

It was not simply brute-forced. Foundational Polish cryptanalysis, Allied work including Bletchley Park, procedural weaknesses, captured material, intelligence, mathematical analysis and Bombe-assisted searches all mattered.

NO SELF-MAPS

With its reflector path, this model never lights the typed letter. That useful property was one clue among many—not a complete explanation for Enigma’s defeat.
