". . . the Russians had destroyed or captured fully a third of the Turkish Third Army — the units linked up against Lyyakhov alone lost 12,000 — and that defeat broke it as a fighting force. Now Yudenich need have no fear of it intervening on the left when he had to face Izzet's Second Army, as he knew he must in the weeks to come. His line was consolidated across the Pontic Alps from the Black Sea coast west of Trebizond to the Eastern Euphrates . . ."
From his victory over the Turks in the Battle of Sarikamish in December, 1914 to January, 1915, through his methodical advance into eastern Turkey through July, 1916, Russian General Nicholai Yudenich has repeatedly defeated Turkish forces in the mountains between the Black Sea, Persia, and the Russian frontier. The largely Christian population had suffered through governmental attacks, particularly the Armenian genocide. On July 13, 1916, Yudenich and Vladimir Lyakhov defeated the Turks on the Kara-Su River at Kotur. With this victory, Yudenich threatened the Turkish heartland.
