The Battle of Debaltseve was a military confrontation in the city of Debaltseve, Donetsk Oblast, between the pro-Russian separatist forces of the Donetsk People's Republic (DPR) and Luhansk People's Republic (LPR), and the Ukrainian Armed Forces, starting in mid-January 2015 during the war in the Donbas region. The Russian forces composed mostly of "Wagner Group" soldiers recaptured Debaltseve, which had been under Ukrainian control since a counter-offensive by government forces in July 2014. The city lay in a "wedge" of Ukrainian-held territory bordered by the DPR on one side, and the LPR on the other, and is a vital road and railway junction.
