Geocache Description:

A puzzle multi-cache with a historic theme. A cryptic and cryptological challenge.

NOTE: COORDINATES ARE NOT FINAL CACHE – just a place you might want to park – especially if you are in the running for FTF! This cache will probably require substantial time in preparation and some work ‘in the field’.

 

February 12th, 1942

"Ah, there you are. I have good news and bad news – mostly bad news and that means some work for you. As you know, Bukit Timah has been overrun along with most of our vehicles, ammunition and water. Our boys fought bravely but the odds were overwhelming. Latest estimate is that we have less than a week’s worth of water left and Percy has put a ring defence around the city.

“One of the last units left at Bukit Timah were our mates in SIGINT, Jones and SamsonThe runner sent with the retreat order never returned and we assumed they’d been captured. Then 2 hours ago we heard Lieutenant Jones almost made it back from behind enemy lines. He was shot by sniper fire only yards from our forward gunner. The gunners pulled him out of the line of fire along with a large sealed duffel bag of equipment which he made them promise to pass on to us. Jones must have given him a scare, grabbed him by the collar, gave him the bag, and pushed a few sheets of paper into his trouser pocket, while he gave the gunner his dying words.

“Machine 29, come back to me Charlie.
Rotor's edge rails papa. Ring 2-25-8.
Four plugs 21 match 39.
Started first time with key 37.”

You’d be tempted to pass them off as half-conscious ramblings and that is obviously the story Jones and Samson had agreed just in case, but he was deathly serious – if you’ll excuse the pun. He made the gunner repeat the phrase until he was word perfect - every word. And he made him promise to burn or eat the papers if he was caught. Then he collapsed and never regained consciousness.

When the gunner’s officer saw the seal on the duffel bag, he sent the gunner to us post haste. Poor chap was almost neurotic by the time we could give him a cup of tea but he is certain he’ll never forget that phrase. He handed over the bag and the few sheets of paper – a coded message, a burnt scrap of newspaper, and … a crossword puzzle.

Here’s the message:

======================================

... and here’s the crossword puzzle, 3 sheets on lined paper …

The gunner’s sorry about the tea stains too. I mean no disrespect, but there wasn’t a chance he was going to crack the crossword in his state and the bag still had the seal so no security breach. On the other hand, I’ve heard the initials BP whispered of you, so hoping you can still solve the odd cryptic – and you’d have to admit this one looks pretty odd. Samson always was a bit of a cryptic nut – a very ‘punny’ person … ah yes … poor chap. At this point I guess we have to presume he’s kicked the old bucket. Seriously though, I’d guess he’d been working on this one for a while – maybe it was his way of remembering operational code-words or something. Anyway, he’s used it in the 20 hours or so they must have been stuck in the back of that tunnel – so just maybe there was some kind of plan in his crazy head. No doubt they destroyed all their own coding machines but it looks like they found this box afterwards and it was obviously too important to leave behind. We don’t know how he got it, but it looks pretty dirty, as if it was buried. There seem to be some other papers in the bag, more coded messages but I’m pretty sure they aren’t as important as what you now have.

By the way, I wish I had more time to help you but let me give you my thoughts on this.

I think there is some kind of plan in Samson’s mind. The phrase from Jones seems to fit with the crossword and it seems to be the initial settings for the machine. The box is German, marked “Wehrmacht” - Army. And I think ‘29’ means 29 Down. I think that one should be easy enough. There are also 2 wheels marked B & C and 5 wheels marked I to V, and there are rings on each which can be set up. There are also some patch cords, but only 4 on this one are in usable condition. I think you need to work out what wheels go in the machine and in what positions.

What else now. Oh yes! That newspaper … just a burnt scrap. Didn’t make much sense of it myself. A page from the Straits Times of 8th of December, 1941 – the afternoon edition I guess. I remember it has some really interesting information like how the Japanese embassy in London was discovered burning documents … before the attacks on Pearl Harbour and Malaya. But there’s an arrow drawn on it pointing off the scrap and some references: 21D, 22A, 1D, 7D, 1A, 11D. You’d better see if you can work out what it was pointing to, so try to find a back issue somewhere – … December seems such a long time ago … they might still have one in a museum!

On another matter … No doubt you realize that if Percy has to surrender then we’ll have to destroy everything before hostilities cease. In that case, we’ll revert to the Pencil and Paper Code. I thought you’d like to be reminded of how it runs – we may need to send some urgent messages before final deactivation of our forces – and then around whatever camps too I guess. I’ve brought along page 23 from the training manual just in case you need to brush up.

Look, I have to go now. But when I get a chance I’ll try to work on this as well. If I come up with anything I’ll let you know somehow, maybe I’ll have to just leave a message somewhere for you to pick up.

 

Additional notes:

This cache is intended to help you learn a little about the Fall of Singapore, an event that Churchill described as the worst disaster and largest capitulation in British history (try Wikipedia: http://en.wikipedia.org).

You will get to visit a fascinating museum where an important event took place. (The sign now has charges for admission but in fact admission is free up until the 65th anniversary of the Fall of Singapore, 15 Feb 2007).

Did you know that cryptic crosswords were used to find and test potential cryptologists? Rest easy, for this one you can take longer than the 12 minutes the potential recruits were usually given.

In order to solve this puzzle fully, you will need to find a way to decode the German cipher machine signals. There are several web-based simulators around, but I found one to download at http://users.telenet.be/d.rijmenants/index.htm.(You might have to solve the crossword to work out which one to use!)

Once you have the crossword solved and the first message decoded you should be able to use your solutions to decode the remaining messages ‘in the field’ using pencil and paper. Further note ... the Decoy micro disappeared and it is not worth replacing. If you get to that point then 'Bang!' consider yourself booby-trapped!

Further note June-2011. I have uploaded the artwork for the micro (and the decoy) as it seems like the micro location might be demolished in the near future. Enjoy!
