German Intelligence was woeful right through the war.
Look at 'Operation Double Cross' for example.
Every agent sent to the UK was captured and most were 'turned' and used to feed fake information to the Germans.
Some were even decorated by Hitler for their services.
They contributed massively to the war effort. Germany took all their information at face value and believed everything.
Some real info was sent with the fake and on several occasion obviously outrageous information was sent just to 'test the waters' but it was all lapped uo eagerly.
Brilliant definitive book. Double Cross (subtitle The true story of the D-Day Spies) by Ben Macintyre
The star was Juan Pujol, code-named Garbo was a Spaniard living in the UK and claiming to the Germans he was operating a network of 24 spies. He fed massive amounts of fake info. He wrote his own book about his exploits in the 80s. Garbo: The Personal Story of the Most Successful Double Agent Ever.
To add insult to the above you can add in mincemeat. The Germans got hold of a dead British officer holding highly classified information about the coming invasion of Scilly or was that Greece? The Germans, as a result of this information diverted resources to Greece and to Northern Scilly. The invasion came in Southern Scilly. This saved many British lives.
The above is what most people know. Later, after D-day, the Germans got hold of REAL information obtained in a similar way. The had enough sense not to be fooled twice. If the Germans had accepted the information it would have cost many British lives.
