World War II: In the early phases of the Third Battle of Kharkov, Red Army troops re-enter the city.
Third Battle of Kharkov
The Third Battle of Kharkov was a series of battles on the Eastern Front of World War II, undertaken by Nazi Germany's Army Group South against the Soviet Red Army, around the city of Kharkov between 19 February and 15 March 1943. Known to the German side as the Donets Campaign, and in the Soviet Union as the Donbass and Kharkov operations, the German counterstrike led to the recapture of the cities of Kharkov and Belgorod.
Red Army
The Workers' and Peasants' Red Army, often shortened to the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army was renamed the "Soviet Army". Following the dissolution of the Soviet Union it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army.
