From what i read, part are 'sleepers' and they will forge the next gen of nazi so to form their version of RAF, but another is akin to the 'werewolf' and they will begin insurgency almost immediately.
The insurgency may start, but they will be crushed by the Allies. And the "redoubt" will be discovered. Even if you kill everyone who worked on it, there will be people in the area who know of some sort of construction. Given sufficient incentive, someone will tell the Allies about it.
The occupation of Germany, at least by the Western Allies, OTL was fairly mild. This occupation will be a lot harsher. The occupation forces won't put up with any shit from the local population.
