The look of the Turkish Officer at the end of that scene, after re-watching it when I was already an adult, left me with no doubts what was going to happen next in the movie.
I've a copy of the "Seven Pillars" but I haven't read it yet. It's among a huge pile of WWI related books waiting to be read.
If I may, I'd like to left here a suggestion for WWI reading: "The Price of Glory" from Alistair Horne and last but not the least "The First Day on the Somme" by Martin Middlebrook. Two classical WWI books, that in my case, expect a full re-reading.

I order for Christmas "Falling Aces" from Peter Hart and am looking, maybe my next acquisition, to "The Somme" by the same author.
