Totally reverse? The Germans had a lot of success early on, especially in British convoy codes.

Vichy code breakers were not working for the Germans and neither were any Poles undercover working for them:sorry cannot find the reference just now, but didn't the Vichy regime have at least some of the Polish code breakers working under their control? (or more accurately continue working under their control)
so there was at least a chance of reveal to Germans? and their Enigma machine could be easily enhanced to foil Allied efforts?

Until November 1942. When Op ANTON was executed the Poles and French cryptologists were evacuated to Spain and filtered out to the UK & Free French.
cannot find the reference, but had the impression that the French were aware of what was ongoing? hence my suggestion that it was something they might exploit, of course Germans never seriously pursued collaboration.
AND wonder if they had received some vague indication that Enigma was less than perfect if they would have even acted?
Supposedly they understood there were issues, but simply didn't think anyone would put in the enormous effort it would take to reliably break it. As it was it took the Allies half the war to do so and pretty major investment of resources to tackle all the different systems.AND wonder if they had received some vague indication that Enigma was less than perfect if they would have even acted?
Part of the problem there is that the intel had been repeatedly wrong. They were continually predicting invasion and had claimed the invasion would be on May 15th (which was the original invasion date but the weather and Balkan campaign changed it) and then repeatedly in May and early June, each time being wrong until of course the 22nd of June. The Germans were also launching their own deception operations suggesting the build up in the East/Norway was preparation for an invasion of Britain, while Stalin saw the Balkan invasion as something aimed at the British due to the push into Greece and fight over Crete. Plus supposedly Hitler personally sent Stalin letters explaining the build up in the East and warning against a potential plot by his anti-communist officers to start a war by a border incident, which when coupled with all of the above would lead Stalin to think the intel coming in was at least in part a British plot to get him to fight Hitler to save them. It also would explain why he demanded border units stand down and not respond to any provocation.Stalin thought British warnings about Barbarrosa were a trap to get him into the war on the British side. Without his paranoia about British dirty tricks would he have taken more notice of intelligence he was recieving from his agents in Tokyo and Berlin.

http://chris-intel-corner.blogspot.com/search/label/TypexAnyone have a take on how vulnerable the British TYPEX or US SIGABA encryption machines were?
Nonsense, the Soviets had their own sources which were incorrect. Even without code breaking the British were also passed info about the Barbarossa plan by German traitors. Saying Stalin had all the info he needed is at very least a glib comment, as he had a ton of false positives and though we can look back with hindsight and criticize him ultimately he was provided with info which was less than he needed to make the correct decision. I'll refer you back to the link I cited from the CIA earlier which explores the reason why what Stalin knew wasn't enough to actually act.If Britain isn't breaking German codes there will be no false warnings. Stalin had all the information about Barbarossa he needed he ignored the best spy network in the world.
