The President planned a new counterattack based on a scientific insight into the future development of the war during the strategic temporary retreat and advanced a policy of forming the second front behind the enemy line by regular armed forces.

On the instructions of the illustrious commander who clarified in detail the basic duty of the Korean People's Army units on the second front and their operation theater, the KPA soldiers formed another large-scale front behind the enemy line, along with the main front and successfully carried out the operational intention of the Supreme Headquarters.

KPA combined units launched their activities behind the enemy line on the order of the Supreme Commander on October 13, Juche 39 (1950). They dealt a deadly blow to the aggressors in the enemy-occupied areas through assault and ambush operations and made a great contribution to ensuring the definite superiority on the main front and creating a favorable environment for counterattack.

During the first operation in the third stage of the war, the KPA combined units launched a strong counterattack on the 8th corps of the U.S. imperialist aggressor forces, the main force of the enemy, in the line along the Chongchon River, while conducting a stubborn defensive operation to check the enemy's attack in the eastern part of the front.

In conformity with such situation of the front, those units on the second front waged a fierce surprise attack to prevent the reinforcement of enemy forces on the main front. They conducted vigorous activities to block the enemy's movement and transport to the front in the areas of Yangdok, Ahobi Pass and Majon-ri and intercept the ties between the eastern and western groups of the enemy in the period from early November to mid-November.

They also conducted a vigorous struggle to liberate vast enemy-held areas including Kangdong, Songchon, Cholwon, Chunchon and Kaphyong and expanded the sphere of their activities behind the enemy line to more than 20,000 square kilometers during the first operation.

They played a big role in frustrating the enemy's scheme for a "general offensive". In keeping with the counterattack of the main frontline units, they launched a powerful strike behind the enemy line to encircle and wipe out the aggressors and foil the enemy's scheme for defence in the mid-area, thus playing an important role in switching the war to a new stage.

Through a close combined operation, the KPA units on the main front and the second front completely frustrated the enemy's attempt at mid-area defence and passed 300-500 kilometers of in-depth area by a single attack and expelled the enemy to the south of the 38th Parallel all along the frontline.

Under the policy of struggle in the enemy lines set forth by the President, more than 40 people's guerrillas and over 60 children's guards and children's guerrillas were organized in different parts of the country, and they performed distinguished feats in the harassment operation behind the enemy lines.

As seen above, with the formation of the second front in the enemy lines by the regular forces, the DPRK people could definitely take the initiative in the war and hasten the victory with confidence. And they set a brilliant example of the unique military tactics, combined strike operation on the main front and behind the enemy lines unprecedented in the world history of wars.
