During the Battle of Moscow, Eberbach spearheaded Panzer Group 2's offensive towards Moscow as the commander of a combined-arms kampfgruppe within the 4th Panzer Division.[4] The attack began on September 30 and in only two days of fighting Kampfgruppe Eberbach had achieved a clean breakthrough, advanced over 120 kilometers, and put the entire Soviet Bryansk Front in a disastrous position while suffering negligible losses of its own.[5] Eberbach demonstrated his flexibility as a troop leader by detaching two battalions to assist the 3rd Panzer Division's efforts in the same area of operations near Bryansk, despite serving under a different division.[6] Soviet air attacks and a fuel shortage early on 2 October failed to prevent the kampfgruppe's aggressive combat leaders from advancing on the city of Orel, ending the Soviet industrial relocation efforts there and capturing a key communications hub of the Bryansk Front, on 3 October.[7] Kampfgruppe Eberbach's losses had been light: 6 tanks knocked out, 34 men killed and 121 wounded.
