Albeit, that this latter name was a false one

According information from the file Part II, it likely was via his mother's second marriage Henri Dubois


The first three were Dutch citizen; third one was according a letter a Belgian, who in the later 1930s lived with an Uncle and Aunt in a suburb of Paris


All were, in someway, involved in espionage attempts against England

during the preparation


The invasion

of Great Britain


late summer or early autumn




German code-name : Unternehmen Seelöwe (Seeloewe); concerning:

The German invasion of England. 

An endeavour wherefore the Germans were definitely not prepared at all!

As it never had been their intention


invade Britain really.

These file series are so extensive, that, for practical reasons, I am forced to divide them into a series of separate chapters.

I cannot yet estimate how many chapters it finally will engender.

I therefore, will extend the numbers after having completed a separate Chapter (Part)

The their transmitter gear, nowhere is a reference of their receiver set; if any

What really is wondering me, is, that nowhere is any reference of a receiver. This would imply that they only could transmit. We have to notice, as we will learn from a British report on this transmitter, that the filament current ( according KV 2/1700-3, page 11) 270 mA (>0.25 A!) a value not to be neglected, and therefore the two square batteries have to function. But, in my perception, in the most favourable circumstances they lasted maybe one or maybe two weeks. 

But, being without two-way communications, their engagements from the beginning must have been considered like a dead-squad; at least most unprofessional.  


For your convenience,

KV 2/1700-3, page 36

Quote:     (d)    The demeanour of the spies was such that they were convinced invasion would take place before the middle of September.  The spies work in pairs and were provided with food for ten(?) days and with £60 in British currency, for expenses to last fourteen days.

                (e)    There was no German contact in England. The spies gave the information that the contact was unnecessary as the German would be here within two weeks.  Each spy had been given instructions of how to signal to the advancing armies in order to cross over and give further instructions.
