The Bergmann Offensive (Turkish: Bergmann Atağı; Russian: Берхманнский прорыв; in Russian literature Russian: Кёприкейская операция, "Köprüköy operation") was the first engagement of the Caucasus Campaign during World War I. General Georgy Bergmann, commander of I Caucasian Army Corps, took the initiative against the Ottoman Empire.
Contact between the armies began on 6 November.
On 15 November, Bergmann's troops crossed the border in the general direction of Köprüköy. On the right flank, a brigade under Istomin moved from Oltu in the direction of İd. On the left flank a Cossack division under Baratov moved into the Eleşkirt valley towards Yuzveran, after it crossed the Aras River.
In response the Ottoman 3rd Army went on a general counter-offensive. As a result Russian forces were threatened by an enveloping movement on both sides. Only quick arrival of Russian reinforcements saved the situation. The fighting finally died away on 29 November.
Russian losses were up to 40% and their morale was shaken. Meanwhile, Turkish morale was high. The success during this first engagement encouraged Enver Pasha in his plan to attack at Sarıkamış.
