there are 3 acts against pontic Greeks,
and one minor
1rst is 1870-80's
2nd is 1908-1916
3rd is 1922-24
and the minor is at 1950's
Pontic greeks who devastet to Con/polis at 1923 were not exchanged due to treaty
but were hunted at 1950's pogrom at Con/polis
the numbers are strange enough,
at 1870's pontic Greeks are mentioned as 3-3.5 000 000, and majority of area, and much bigger than population of Greece of 1860's (Makedonia Thrace Epirus not included)
but we have islamization after Russo-Turkish war and mass exile
leaving to 1 500 000 around end of WW1
and only about 500-600 000 left area at 1923
via the Neutral forces ships
some Historians say that analogy at Oinoe Ortu and Fatsa before 1860 was 5 Greeks 3 Turks 1 Armenian 1 other (Laz Iranian Russian etc)
and at Kars was 5 Armenians to 2 Greeks to 2 Turks
the less Analogy for Greeks was at Kastamone and Sevasteia/Ceasareia (Kastamonu Sivas Kayseri)
at Sevasteia and kaisareia there were 2 Greeks per 6 Turks
The Sultan's firman of 1855 of religious freedoms etc etc if remember correct gave number at 1860-70 that strangely were not expected.
from the Pontic Greeks that live here in my area
major loses were not by Topal Osman,
but mainly due to working camps the
Amele taburu (Taburlari)
around 250 000 Greeks Lost their lives at these camps,
2 cases that must mentioned are the case of Tamama-Eleni,
that become a movie,

and the other is Konstantinos or Murat,
who Become Turkish military officer to a high degree
both were found kids abandoned and adopted by Turks
and learn their origin at 1970's -80's.
The adapted kids that Andreadis found are many,
and only he knows the number.
He spend a lot part of his life cooparating with Internaional organisations, and Turkish Authorities to find lost Kids
the 2 most interesting become books and movie
