Nor Wikiipedia, neither Google says anything about the "Mysterious Duo", therefore some of the historians claim that it didn't exist. Others say that they're tibethan intelligence's product. Why tibethan government would be interested in such an action, no one knows. David Irving, british historian, insists that both of them (Gen. "X" and Gen. "Y") was sent to assasinate Jodl while he was bothering Hitler. If yes, they failed, because Jodl did died in completely diffrent circumstances. Gathered information about "Mysterious Duo" from various sources:

General "X"
His national identity is unknown, but one is certain - dark hair and a bit exposed ears do not make him Aryan. "Forehead suggests that this man has mesopotamian descent" - it's dr Buckley's' from University of Yale opinion. Oppose to that, mr John Coleman from "British Royal Antics" organisation claims - " After many studies we know with every assurance that this man is just a wall painitng, considered as an another Fegelein's antic".

General "Y"
He keeps pokerface all the time, so that it makes very difficult to identify him. He has petrified mimics, but sometimes looks at the Jodl, no one knows why. Supposingly he's in constant coordination with Gen. "X". It seems suspiciously that some of the Untergangers hide his face. Always behind Jodl.

Note: If anyone knows something more about the "Mysterious Duo", it would be glad to share the info.
