ETO - UK: Alan Turing's first "Bombe" decipher machine becomes operational at Bletchley Park.
The working rebuilt Bombe at Bletchley Park museum, 2008
The Bombe was an electromechanical device used by British cryptologists to help decipher German Enigma-machine-encrypted secret messages. The Bombe implemented a very ingenious algorithm for testing Enigma settings, rejecting all but a very few as inconsistent with the data.
The Bombe was the brainchild of mathematical genius Alan Turing and was designed to discover some of the daily settings of the Enigma machines on the various German military networks: specifically, the set of rotors in use and their positions in the machine; the rotor core start positions for the message (the message key) and one of the wiring of the plugboard.
To decipher German military Enigma messages required that two settings of the machine be discovered:
1) internal settings that required the lid of the Enigma machine to be opened and 2) external settings that could be changed without opening the machine.
Once these were known, all the messages for that network for that day (or pair of days in the case of the German navy) could be completely decrypted within two to five hours.
A subsequent US Navy version of the Bombe
The US Navy and US Army later produced their own Bombe machines to the same functional specification, although engineered differently to each other and to the British Bombe. The US Navy version contained 16 four-rotor Enigma-analogues and was much faster than the British three-rotor Bombes, even for a three-rotor task.
After WWII, some fifty Bombes were retained, while the rest were destroyed. The surviving Bombes were put to work, most likely on Eastern bloc ciphers. The official history of the Bombe states that "some of these machines were to be stored away but others were required to run new jobs and sixteen machines were kept comparatively busy on menus."
The bottom line is that the efforts of Poles (who first built a working version of the German Enigma machine), the innovations of Alan Turing and the codebreakers at Britain's Bletchley Park, the US Army SIS and the US Navy OP-20-G not only played an important role in the outcome of WWII, but led directly to today's modern computing.
It is said that the name "Bombe" was dubbed by the original Polish codebreakers after the frozen dessert.

Germany: The Kraków Ghetto in German-occupied Poland, created for the purpose of persecution, terror and exploitation of Polish Jews, is liquidated. Most are sent to Belzec and Plaszów and will be exterminated at Auschwitz.
A column of Jews march with bundles down a main street in Kraków during the liquidation of the ghetto. SS guards oversee the deportation action.
The Krakow Ghetto had crammed 15,000 Jews into an area previously inhabited by 3,000 people. As a result, one apartment had been allocated to every four Jewish families, and many less fortunate had been forced to live on the street. Even all the windows and doors that looked over the surrounding walls onto the "Aryan" side of Krakow had been ordered bricked up.
