The Orel–Kursk operation halted Denikin's advance on Moscow and defeated the main White shock group, opening the way for the Red advance on Kharkov and the Donbas.
Along with the simultaneous Voronezh–Kastornoye operation, it marked a turning point in the fight against the Armed Forces of South Russia, creating favorable conditions for the advance of the Southern and Southeastern Fronts in 1919 and 1920.
The loss of Kursk and Kastornoye broke White morale, preventing them from resisting the Red advance in pitched battle, and precipitated a White retreat that lasted until they reached the North Caucasus.[6]
The strategic initiative on the front was gained by the Red Army, but it did not manage to destroy the Volunteer Army's main forces, due to weak communications between the armies, the inability to build up sufficient reserves during the offensive, and command shortcomings.
