The Battle of Donbas was a military offensive that was part of the wider eastern front of the Russo-Ukrainian war. The offensive began on 18 April 2022 between the armed forces of Russia and Ukraine for control of the Donbas region. Military analysts consider the campaign to have been the second strategic phase of the invasion, after Russia's initial three-pronged attack into Ukraine.
Russia's strategy in the sector was to encircle Ukrainian troops in the Donbas and to annex the entire Donetsk and Luhansk oblasts to the Russian-backed separatist states of the Donetsk People's Republic (DPR) and Luhansk People's Republic (LPR). Russia claimed to have controlled 55% of Donetsk Oblast by 23 June 2022 and all of Luhansk Oblast by 3 July 2022, with Russian and separatist forces controlling the cities of Mariupol, Sievierodonetsk, Lysychansk, Rubizhne, and many others.
