We were surprised to find that they had also been able to decode messages sent by Japan. We quote from the material posted on the war describing just one thing that the de-coders found out about Japan: "The code-breakers in Bletchley Park broke the Japanese Military AttacheCode between Berlin and Tokyo and knew from 1943 on, the Japanese were buying uranium and strontium from the Germans. We have the cardin our archives. This shows the cargo carried by submarine blockade-runners from Germany to Japan and visa-versa. U-234 was carrying a jet fighter….

In May 1945, U-234 surrendered at Portsmouth, New Hampshire and inside six lead cylinders were 570 kilograms (1232 pounds) of uranium on its wayto Japan. If you were Harry Truman, President of the U.S., what would you have done?"

In spite of the large number of people who worked there, the secret of the existence of the unit was kept until 1969. No one talked about it for years. The funniest story was that one of the guides was making just this point to a group of tourists recently, and one of the older women in the tour group said, "I used to work here". At this point, her husband said, "So did I." Neither one had told the other all these years! If that isn’t amazing, we don’t know what is.

Bletchley Park was one of the most interesting places we’ve been in. We’re so glad that Harry et alia was willing to make the trip – and even happier to find that they liked it so much that they arranged to re-visit it in the future!
