Izyum–Barvenkovo offensive
The Izyum–Barvenkovo offensive (17 July 1943 – 27 July 1943) was a Soviet offensive operation of the Southwestern Front against part of German Army Group South during the World War II. The aim of the operation was to tie down German reserves during the Battle of Kursk and overrun the German forces located in Donbass. Soviet troops managed to cross the Seversky Donets river and seize the bridgehead, but the German counterattacks stopped the further advance.
