I know it was the Metaxas line, named after the dictator General Metaxas. Or a famous brand of Ouzo, take your pick.

Metaxas was pretty much airbrushed out of Greek History for a while, after all he was a military dictator appointed by the Monarch so post-war it wasn't the sort of thing to shout about. It was pierced by the German XVIII Corps, but was pretty much outflanked anyway. By this time the key allied defense had moved south to the Aliakamon position. The 3 Greek Divisions manning the front refused to withdraw south, and paid for it.
