ENIAC and Bombe
I knew ENIAC in an electronics handy book at first. It said, 'the first programmed electronic computing machine in the world'. Several years later, I knew Turing Machine in a programming book, written in English originally. Alan Turing(1912-1954) worked at Bletchley Park to break enemy cipher and suceeded. The machine was called Bombe.
Signal intelligence of powers and MOFA of Japan
Germany broke cipher of MOFA completely at first which was called Purple in US. Germany warnmed Ambassador Oshima that allied nations read codes of MOFA in a polite way on Apr 1941. Pherhaps Germany was afraid that her military information leaked via MOFA. US used a lot of punch card machines to sort codes. Germany and Japan had imported the machines from US. How Germany and Russia could break Purple without machines?
IJN code was broken, so the battle of Midway and kill of Yamamo occurred. Once Genda said, 'There is no way to win with the kill of Yamamoto because of cracking IJN cipher'. MOFA and IJN had not made effort to improve how to handle cipher machines because they did not mind securities of Japan. They were much busier in their domestic ministris' rights to confront IJA. Japanese embassy of Spain got a faint information of US nucler delopment, but cracking of ciphers occurred deaths of agent in the US.
I count up books on my shelves about intelligence and cipher. Japan fought only information. Leaders of IJA and IJN often ignored opinion of intelligence section. Only operation section of IJA and IJN planned the war. How united organization did not always work well?
