 "When the Russian armies invaded Turkey after the Sarikamish disaster 
  of 1914, their columns were preceded by battalions of irregular 
  Armenian volunteers, both from the Caucasus and from Turkey. One of 
  these was commanded by a certain Andranik, a blood-thirsty adventurer.
  These Armenian volunteers committed all kinds of excesses, more
  than six hundred thousand Kurds being killed between 1915 and 1916 in 
  the eastern vilayets of Turkey."
