A nazi invasion of Ireland?

I strongly suspect this is bullshit. If such a plan really did exist, it was probably nothing more than a ruse to try and fool British intelligence and pull resources away from the defense of Southern England. There is absolutley no way Germany had the air or seapower to attempt such a landing. No Way. In the end, the nazis knew they didn't even have the resources to cross over from the Pas de Calais. And the idea that a small army would be "living off the land" like the armies of two centuries earlier is preposterous. The Germans never would have considered such an invasion until after the occupation of Britain itself. Somebody's being conned...
