The Metaxis Line O. Was a Hundred, 30 Mile Long Series of Concrete Bunkers

The british knew the germans were not going to be able to simply be brushed aside like the italians aa had been. They warned the greeks that maybe falling back and not holding thisa worked against the italians oakin. The problem was with yugoslavia of the war, they could now be invaded from ther direction, which exposed the flank of the mtaxis line. Because it was concrete bunkers and shit, you can't move to meet that threat. And that's exactly what happened.
