The Bergmann Offensive (; ; in Russian literature , "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 armias began on 6 November. 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.
