It is contemporarily relevant to look at the euphemistic 'exchange of populations' during and after the Greco-Turkish War. Today it would be called 'ethnic cleansing'. In Anatolia itself, it took the form of genocide. The Turks had recently executed the Armenian and Assyrian (Sayfo) genocides.

Most vividly, it was covered by journalist Ernest Hemingway for the Toronto Star:

   A Silent, Ghastly Procession Wends Its Way from Thrace (20 Oct 1922)
   Refugee Procession is Scene of Horror (14 Nov 1922)

But he also put his experiences into fiction, especially "On The Quai At Smyrna", describing the tragic murderous evacuation of Greeks from (what is now) Izmir, Turkey.

You can find these works in many collections of his journalism and short stories (e.g. "Byline"). I am very glad his early work is now coming out of copyright (and the journalism in Canada too? - if someone has links to his original articles, please post them).

Here is an out-of-copyright paragraph of "In Our Time", which recollects the refugee columns passing through Thrace, to and from Salonika, in 1922:

There are similar scenes in our world today. Not being played out today, but really happening.
