CAIRO – 28 June 2022: On June 27, 1940, the Germans established two-way radio communications in their newly occupied French territory, using their most advanced encryption machine, the Enigma, to transmit information.
The Germans established radio stations in Brest and the port of Cherbourg. The signals would be sent to German bombers to direct them to targets in Britain.
The Enigma cipher machine, invented by Dutchman Hugo Koch in 1919, looked like a typewriter and was originally used for commercial purposes, according to the History website.
The German military adapted the machine for wartime use and deemed its encryption system unbreakable, but they were wrong because the British had cracked the code early in the German invasion of Poland and virtually intercepted every message sent through the system. Britain named the intercepted messages Urtla.
It is worth noting that explorers have found the deepest shipwreck ever identified, where a US Navy destroyer sank during World War II. According to the BBC, the USS Samuel B. Roberts was plunged into battle off the Philippine Sea in October 1944 and is located in 6,895 meters (22,621 feet) of water.
