It is well known that the history of Allied successes in breaking German codes during WWII has been exhaustively researched, documented and published by numerous WWII historians, as well as by the Western media in general. Consequently, these historians and commentators have not only acknowledged these Allied successes, but at least in some cases, they’ve exaggerated their importance in terms of the actual effect on the outcome of several military campaigns. Part of this shortcoming, is that the work of the Axis code breakers, working at the same time, has received very little attention or .acknowledgement. 

In a well researched series of essays,  Christos Triantafyllopoulos has started to redress this striking omission from WWII history, and in the process reversed the perception (or even myth) that Soviet and Western Allied codes were somehow ‘unbreakable’, or that Axis intelligence simply failed to break them.
