In August 1919, he was at the headquarters of the 8th Army, and as part of Vladimir Selivachyov's army, participated in the Southern Front counteroffensive against Denikin's forces. The offensive was successful, and by 25 August the cities of Volchansk and Kupyansk were occupied, but by 26 August the situation had changed. Under the threat of encirclement, Kupyansk was abandoned, followed by Voronezh. During the time, the rear of the 8th Army of the Red Army came under attack from Konstantin Mamontov's cavalry units from 10 August to 19 September 1919.

On 7 September 1919, Selivachyov decided to transfer control of the military group to military specialists A. I. Rataysky and Gorchakov, appointing the latter as its chief of staff. Selivachyov himself went to the 8th Army, which found itself in the most difficult situation, where he assumed temporary command. Communication with the headquarters of the Southern Front was lost, and under threat of encirclement, parts of the military group began to retreat to the Novy Oskol area. During these events (September 16), the headquarters of the Southern Front received a telegram from Lenin, in which he shared his fears of possible betrayal on the part of Selivachyov and his division commanders. On 17 September, Selivachyov suddenly died of typhus, and the very next night, Nashtarm A. S. Nechvolodov and his wife defected from the 8th Army headquarters to the Whites. On 20 September, units of the 8th Army abandoned Kostomarovka and Kursk. By 30 September, the Whites had reoccupied Voronezh and Liski. At the same time, Mamontov's corps made its second raid on the Red rear. The 8th Army was under threat of complete defeat, and many high-ranking military specialists left their service. Only from 2 October to 6 October 1919 did the following defect to the Whites: the head of the army intelligence department, V. A. Zheltyshev, the acting chief of staff of the army, V. F. Tarasov, the head of the army operations department, B. P. Lapshin, and the chief of the army rear staff, V. V. Vdovyev-Kabardintsev.

On 24 October 1919, units of the 8th Army with the support of Budyonny's Cavalry Corps, finally occupied Voronezh. Gorchakov was finally granted leave to improve his health, but by the of end December 1919 returned to staff work, taking up the post of chief of the operational department of the 8th Army. The military specialist's further combat path was associated with the Rostov-Novocherkassk, Don-Manych, and North Caucasian operations, ending with the complete defeat of the Whites in Novorossiysk.

Turkestan Front In the autumn of 1920, Gorchakov was transferred to Central Asia to the Turkestan Front. From 18 September 1920 to 3 October 1921, he held the position of 1st assistant to the chief of staff of the Turkestan Front under the chief of staff of F. P. Shafalovich. The commander of the Turkestan Front at that time was his former colleague from the 8th Army, Grigory Sokolnikov, followed by V. S. Lazarevich. Gorchakov took an active part in the development and implementation of military operations of the Red Army units against the Basmachi.

Polish–Soviet War

At the end of May 1920, Gorchakov took up the post of Chief of the Operations Directorate of the 4th Army of the Western Front of the RSFSR. He was part of the lead army group during the July offensive operation. On 10 July and 13 July 1920, he signed operational orders for the 4th Army. On 14 July 1920, the Army's troops occupied Vilnius. On 19 July 1920, during a deep outflanking maneuver, Gai's 3rd Cavalry Corps, also part of the 4th Army, occupied the fortress city of Grodno. This event was a big surprise for both the enemy and the Red Army leadership. The next day, the 9th and 17th Infantry Divisions and 3 Uhlan Regiments of the enemy were sent from Bialystok to help the besieged garrison. Despite this, the 4th Army headquarters needed to be made aware of the events due to the lack of communication with G. D. Gaia. The 4th Army Commander, E. N. Sergeev, was in Vilnius and was conducting diplomatic negotiations with the Lithuanian authorities at the time to determine the latter's further actions. By 22 July, there was still no communication with G. D. Gaia,Н. Какурин, В. Меликов «Гражданская война в России: Война с белополяками 1920 год» АСТ Москва 2002, Стр. 306 and the soldiers of the cavalry corps left without support, were engaged in the heaviest street battles in dismounted formation. Then, units of the corps began to lose the positions they had occupied, gradually retreating to the Neman River.

At the same time, the main forces of the 4th Army stopped at the distant approaches to Grodno, fulfilling the directive of the 4th Army Commander No. 1058. Concerned about the prolonged lack of communication with the cavalry corps, the 4th Army Commander sent his trusted and authoritative person to Grodno. The head of the Operations Directorate, Gorchakov, became the head of the Operations Directorate and immediately left for Grodno by car. He arrived at the headquarters of the 3rd Cavalry Corps on horseback. In the area of Grendychi, his car got stuck in the sand and was then fired upon by enemy artillery. Directive to the troops No. 1058/20.06.1920 was no longer relevant to the situation that had developed at that time. After a meeting at the headquarters of the Cavalry Corps, Gorchakov took responsibility for the regrouping of the divisions of the 4th Army. As a result of the regrouping of the units, strategic success was achieved. On 23 July 1920, after heavy fighting, Grodno was recaptured from the Polish forces. For the successful conduct of the Grodno operation, the Chief of the Operational Directorate of the 4th Army, Gorchakov was awarded the Order of the Red Banner of the RSFSR No. 97 (Order of the Revolutionary Military Council No. 458/1920) and Certificate No. 1564.
