Operation Century Mystery Cache

This cache has been archived.

Woking Wonders: Even before yesterday's visit by d120874n we had been considering what to do with this one. It gets done so infrequently and I was afraid there might be problems with some of the stages.

I walked the route today finding that some stages were indeed missing (two hosts had been removed, and another had suffered where vegetation has been cut back).

Therefore we have decided to archive this (final has been removed, as have those intermediate stages where I could find them).

Geocache Description:

WW's wanted to do something a little different to celebrate 100 placed caches. So we came up with this idea.

Park in the car park at the specified co-ordinates

The nearby SOE training centre at Tyting House by St Martha's Hill near Guildford housed a highly sensitive Security Section. The house had been requisitioned by the Special Operations Executive and was designated as a Special Training School where agents assigned for covert operations in enemy territory were appraised. Later it was used for processing agents returning from operations and was where they were accommodated until they could be returned to normal life once it was deemed that they no longer presented a threat to those agents still in the field. Tyting House was converted into council flats after the war, but having later fallen into disrepair was demolished. Tyting Farm, originally part of the estate, remains today and is currently leased to the Surrey Wildlife Trust.

What was the number of the special training school (AB)

What year was the house requisitioned (19CD)

The first waypoint (don't leave home until you've solved it) is at :

N51 13.(C+1)(A-D)(B-(A/D)) W000 32.(A+1)(B+1)(A/D)

Whilst doing this cache you will visit several other waypoints. Do not be surprised to come across odd clues on route & you may have to return home or a mobile phone maybe useful. There is a theme which should become apparent early on with this cache.

We would like to acknowledge Brambler's excellent Pitch Series which was the inspiration for this cache.
