Also known as the Svatove–Kreminna line or the Kupiansk–Svatove–Kreminna–Bilohorivka line after the major settlements along the front, the campaign began a day after the Ukrainian Army recaptured the nearby city of Lyman during the Kharkiv counteroffensive after of which the front line froze over the next few months.
