The Enigma Machine allowed the Nazis to transmit encoded messages during World War 2. (https://brilliant.org/wiki/enigma-machine/)It seemed messages encoded from the Enigma Machine were impossible to decode or figure out what they meant. It seemed as if Scherbius made it perfectly, and impossible to figure out unless you were a Nazi. Until one summer night in 1941, when the impossible became possible.

The first decoding of the Enigma Machine starts when the Nazis invaded Poland in 1939. The Englishmen intercepted almost every message that were sent through the occupation of Holland and France. Then in 1941 the Nazis invaded Russia, and the Allies intercepted more coded messages. The first breakthrough happened on July 9, regarding the Nazi ground-air operations, but then they decoded various valuable messages over the next year, each containing information of higher value. The messages were then passed to the Soviet High Command so they could plan attacks and ambushes, and then back to London regarding the mass murder of Russian prisoners and Jewish concentration camps survivors.(https://www.history.com/this-day-in-history/enigma-keybroken#:~:text=On%20July%209%2C%201941%2C%20crackerjack,codes%20for%20the%20Western%20front.)
