 Soviet offensive operations for the summer of 1943 were planned to begin after the strength of the German forces had been dissipated by their Kursk offensive. As the German momentum in the north slowed, the Soviets launched Operation Kutusov on 12 July against Army Group Centre in the Orel salient, directly north of the Kursk salient. The Bryansk Front, under the command of Markian Popov, attacked the eastern face of the Orel salient while the Western Front, commanded by Vasily Sokolovsky, attacked from the north. The Western Front's assault was led by the 11th Guards Army, under Lieutenant General Hovhannes Bagramyan, and was supported by the 1st and 5th Tank Corps. The Soviet spearheads sustained heavy casualties, but pushed through and in some areas achieved significant penetrations. These thrusts endangered German supply routes and threatened the 9th Army with encirclement. With this threat, 9th Army was compelled to go over fully to the defensive.
