troubling claims
There are rather a lot of errors in some recent edits. I have corrected some of these, but am merely suspicious about others (such as the tunnel claims). Someone with direct knowledge of Bletchley should review some of the statements made. As of this date, this is an unsatisfactory article due to the (possibly) erronious content which remains.

- ww -- could you point out the statements about which you have suspicions (perhaps copying them to this talk page)? Even if they turn out to be completely accurate, it would be good to have sources... — Matt 09:55, 2 May 2004 (UTC)
- Matt, Wilco. As below, noted with **xyz** -- from article.
- Bletchley Park has been credited variously with shortening the war by two years (possible due its contributions during the Battle of the Atlantic, but distinctly controversial), with **ending the bombing of Pearl Harbour** (impossible) by sending information of the **location of Yamamoto the head of the Japanese Combined Fleet ** (quite a dubious claim as the information which led to his death came from breaks into JN-25 largely by USN cryptanalysts). **Montgomery would often talk of how the code-breaking efforts of Bletchley Park enabled him to 'know what the Jerries [Germans] are having for breakfast'.**
- The Government Code and Cypher School (GC & CS), the intelligence bureau responsible for interception and decryption of foreign transmissions amongst other things, moved into the Park in 1939. The radio station that was constructed in the park for its use was given the codename "Station X", a term often erroneously applied to the code-breaking efforts at Bletchley as a whole. Station X was soon moved south to Whaddon Hall, to divert attention from the Bletchley site itself. **To further the disguise of Bletchley Park, it was built to appear as a hospital from above to deter bombing by German planes. However, a bomb was dropped next to the despatch riders' entrance, shifting the whole of Hut 4 (the Naval Intelligence hut) two metres on its base.** The bomb was thought to have been intended for Bletchley railway station.
- **The codebreakers would enter the park by coach or train, and it is rumoured that there was a series of inter-connecting tunnels and chambers below Bletchley Park that allowed workers to get in secretly. It is also rumoured that one tunnel, which started in the Park grounds and emerged in the local pub, was for the use of Winston Churchill. It is also said that Eisenhower and Churchill had a meeting in one of the rumoured chambers.**
- I know, and have learned, absolutely nothing about the history of the place prior to Leon. All of this in the article may be spot on, but ???

status of Colossus as first xxx computer, esp in re Zuse
Because of the importance of Betchley Park for the field of Computer Science someone should correct the statement where it sais the Collossos was the world's first programmable computer. That information is incorrect - the earlier success of Konrad Zuse in building a fully electronic computer (Z1, Z2, Z3) were largeley ignored in Nazi Germany. I think that information is especially interesting in relation to Batchley Park, because Germany apparently had access to superior technology for cryptography at the time - luckily didn't realize it!
- I am not so sure about this. Wikipedia says that Colossus was the first programmable electronic computer, whereas the Zuse machines were based on telephone relays and were therefore electrical, not electronic. -- Heron 16:21, 21 Jul 2004 (UTC)
- Heron, You are correct. The article claims (or at least claimed when I last reviewed carefully) that Colossus was the first 1) electronic, 2) programmable 3) digital computer. Vannevar Bush's analog computers were neither electronic nor digital, but pre-dated Colossus. The ABC machine was electronic but not programmable, and pre-dated Colossus. The Zuse and Stibitz (Bell Labs) relay machines were not electronic and were (variably) programmable, but pre-dated Colossus. Babbage's Analytical Engine design was digital and programmable but not electronic, and well pre-dated Colossus. It is the combination of points that is the unique priority for Colossus. ww 20:44, 21 Jul 2004 (UTC)
- Thank you, ww. Our article "History_of_computing_hardware" has more details, for anyone who wants to follow this up. -- Heron 08:03, 22 Jul 2004 (UTC)
- A later note. After reviewing Colossus material in great detail (to far more depth than we have in our article), I would not describe Colossus as "programmable", at least in anything like the sense we now think of the word.
- For one, there was no program, in the sense of an algorithm, with transfers of control, especially conditional transfers. The commonly-reported line about Colossus having some conditional testing is true only in a very limited sense; at the end of each pass of the tape loop, it could compare the contents of counters with pre-set values (in switches), and would print or not print the totals in the counters if they exceeded the preset values.
- All Colossus could do, really, was read paper tape, perform certain plug-selected binary operations on one or more of the bits of each frame read from the tape (usually only 2 channels out of 5 were looked at), and depending on the output of that binary function, increment counters. That's all. It was really incredibly specialized to the job of doing statistical analyses on the key/cipher stream of the Tunny cipher.
- The novelty of Colossus lies in the technology, more than the architecture: it was certainly the first large-scale electronic digital device, and thereby had a great influence on post-WWII computer development in the UK (since many of the leading lights in that field, such as Newman and Turing, were intimately associated with Colossus).

hut, hut, hike
Matt, I can't pretend to remember the Hut numbering, but the one I seem to remember is Hut Six. It's the title of Welchman's book, after all. That implies that Six was responsible for Naval Engima, not as the list is now Army and AirForce variants. Since you've clearly gotten this from a list, could there have been a list - brain - fingers obscuration. Appropriate for the crypto corner, eh?, but confusing to the non-cryptiac.
So, Six or not Six, that is ... never mind... ww 14:57, 3 Aug 2004 (UTC)
- The list was amalgamated from a couple of online sources (one was http://www.codesandciphers.org.uk/bletchleypark/tour4.htm). It seems that huts 6 and 3 were paired and dealt with army and air force traffic; 6 did the codebreaking while 3 housed the intelligence analysts. Similarly Huts 8 and 4 were paired for Naval Enigma. — Matt 22:57, 3 Aug 2004 (UTC)
Rumours
I've moved the following rumours here for now:
The code breakers would enter the park by coach or train, and it is rumoured that there was a series of inter-connecting tunnels and chambers below Bletchley Park that allowed workers to get in secretly. It is also rumoured that one tunnel, which started in the Park grounds and emerged in the local pub, was for the use of Winston Churchill. It is also said that Eisenhower and Churchill had a meeting in one of the rumoured chambers.
Does anyone have a source for these rumours? I haven't come across them after reading a number of BP books, so I'm not even sure these are notable enough to include, but I'm willing to be proved wrong! — Matt 20:23, 6 Dec 2004 (UTC)
