The Battle of Erzincan was a Russian victory over the Ottoman Empire during the First World War. In February 1916, Nikolai Yudenich had taken the cities of Erzurum and Trabzon. Trabzon had provided the Russians with a port to receive reinforcements in the Caucasus. Enver Pasha ordered the Third Army, now under Vehip Pasha, to retake Trabzon. Vehip's attack failed and General Yudenich counterattacked on July 2. The Russian attack hit the Turkish communications center of Erzincan forcing Vehip's troops to retreat as well as losing 34,000 men, half taken as POWs. As a result, the Third Army was rendered ineffective for the rest of the year and Erzincan was captured by the Russians.
