Fashion-Censorship-2-bar

In a British censorship manual from WW2 two pictures containing hidden messages are displayed. Many have tried to find these messages, but up until now with no success.

Last Friday I gave a presentation about steganography at the annual meeting of the high IQ society Mensa. For 90 minutes I talked about null ciphers, acrostics, semagrams, and other kinds of hidden messages. Most of the material was taken from my the second edition of my book Versteckte Borschaften, which will be published in a few weeks.

In my talk I mentioned the two most important unsolved steganographic mysteries I know. Both are contained in a British censorship manual from World War II. A scan of this manual, which is kept by the British National Archives (KV-2-2424), is available here for download. It’s a fascinating read. I have blogged about it a few times before. Comments from my readers helped me to better understand the examples given in the manual and to learn more about the background.

 

Mystery 1: A message hidden in a fashion drawing

The first unsolved mystery is displayed on page 14 of the censorship manual. In the following fashion drawing a message is hidden:

Modezeichnung-1

As can be read below the picture, the hidden message has two parts. The first one is (in English): “Heavy reinforcements for the enemy expected hourly”. The German original reads as follows: “Massive Feindverstärkungen werden stündlich erwartet”. This message is encoded in morse code. The dots and lines are somehow hidden in the three ladies on the top.

Fashion-Signature

The second part of the message is (in English): “Before Arras.” According to the manual, it is contained in the signature – written in a French shorthand. The German original is not mentioned, but only “Vor Arras” makes sense to me. Arras is a town in Northern France.

So far, I could neither find the morse message nor the shorthand message. I even went to the British Archive in London to look at the original document and to take high resolution photographs (like the following one). It didn’t help.

Mystery 2: A message hidden in a map

The following map is displayed on page 17 of the censorship manual:

Modezeichnung-3

This map represents the second mystery.

As can be read below the map, the following message is hidden in it (translated to English): “Oil has arrived, everything is ready. Gustav available for the appointed day.” The German original is not given in the manual. It might be something like: “Öl ist angekommen, alles ist fertig. Gustav hält sich am vereinbarten Tag bereit.”

Again, the message is coded in the morse alphabet (plus a transposition of 11 positions forward), which means that some elements on the map stand for dots and some others for lines. So far, nobody has identified these elements.

Here’s a high resolution picture I took in the National Archive:

Can a reader help?

As mentioned, I have blogged about these two hidden messages several times. I wrote about them in the first edition of my book Versteckte Botschaften. I reported on them in several peresentations. Many tried to find the solution, but to no avail.

If you have an idea how these messages are coded, I would be very interested to learn.

    Hey,
    some Idea to the Map-Puzzle,
    what about finding old Maps of Amsterdam(When im Right) from the same Year, erase all Points, Names Rivers, etc what match in both maps and check what is left. If u cant find the Needle, make the Haystack smaller!
    I trieded to find old Maps, but all are behind a Paywall.

    I have an idea on the fashion puzzle:

    We are assuming that the intent of the censorship publication would be to accurately display the characters used, so that the reader could then see exactly HOW they are used. But that may not be the case… the only intent might be to demonstrate where and in a very basic way how they might be. If this is so, then:

    The publisher might not have considered, nor cared, that the original cipher drawing be adequately represented in the manual. The publishers technical method of photographing, copying, printing might have lost the necessary detail, I mean, to read it… and the publisher might not have cared, as being able for the reader to see it properly may have not been their intent.

    Continuing with that thought… as others have surmised, I would suggest that the form of Morse code is in the borders which are “ladder-like”. Perhaps, as one possible, on the original the little ladder “rungs” don’t meet the border for dot represenation; or perhaps some are thicker, or thinner, to make the distinction.

    Perhaps, even, the original cipher drawing is in color, with different colors denoting “dots” and “dashes”.

    It was great you managed to see and photograph the original manual… but if my guess is correct, it would be the original German cipher illustration which must be seen, to adequately descern the code’s subtleties, in order to know how it was used.

    Regarding the shorthand: If you look at the surname “Shaw” you can recognize (in german shorthand) the words “von aras” if you remove the first line of the “h”. In shorthand there are no double consonants. See the symbol translation at http://steno.tu-clausthal.de/DEK.php?DIR=DEK&Input=von+aras&Proof=0&Scherung=15

    Regarding the map, a solution has already been posted here. I could reproduce the reading of “llesfertig” and a few more fragments, at that time.

    @Norbert:
    Thanks for the hint. The comment says: “… below the dashed line running along raadhuisstraat, there are little pen marks, single strokes for dots, small filled boxes for dashes. Starting near keizersgracht eastwards (or should this be hubward in this particular city) i can make out ‘aathut’, which, when rotated 11 positions forward, gives ‘llesfe’, which could well be part of ‘alles fertig’ for ‘everything is ready’.
    There also seems to be morse code between kalverstraat and rokin. But as i have to look up every single character i don’t try to read more :o)”

    All this makes sense. However, it is difficult to read the whole message.

    @Gerry:
    Thank you very much. This makes sense.

    The fashion drawings are interesting.
    I dont think that the code is hidden in the dots, but the lines in the bordure. Every Model, except for #4 has these bordures in one or another form. Unfortunately they are very small, I think it may be something like two lines representing a dot and three a line.
