The Russian Empire's response

The Russian Empire's response to the bombardment of its Black Sea naval ports was primarily a land campaign through the Caucasus. Early victories against the Ottoman Empire from the winter of 1914 to the spring of 1915 saw significant gains of territory, including relieving the Armenian bastion resisting in the city of Van in May 1915. The Russians also reported encountering the bodies of unarmed civilian Armenians as they advanced.
