Where is this?

No..
In some places it's just a fathom wide gorge.

 

Maybe it's time for another clue..
After retreating throw this gorge the defeated army was shipped to Egypt..

 

Is it the Bouraikos* gorge in the prefecture of Achaea on the northern coast of the Peloponnese . . ?

* also called ‘‘Vouraikos’’ a matter of how to translate ‘‘Βουραϊκός’’

Was it the Ottoman Turks in 1828?

 

To Angel:

Not that either.. No railway here. Only by foot or a donkey ride.. And we are not on the mainland Greece..

 

No, much later..

 

I think this is the proper time frame. Not a wild guess.:

 

excactamente..

 

Ah... I tought it was the mainland because of this clue ‘‘was an important route of a defeated army ones’’. I tought a long route was meant here, so on mainland.

Crete was popping up all the time but I excluded that because it's an island.

So if an island, I go for Crete. Manny gorges there. I'll go for the Samariá Gorge.

Almost there but not quite...

 

Is Crete right..?

Oh yes!

 

Royal Hellenic Army in the Middle East

 

Many gorges there, in fact most of them here are on Crete. But I have no more time today, so it is for some one else to explore . .

Good Luck..!!

One of them..
