In the latter half of the 1930's, the Japanese imperialists pressed ahead with preparations for a war of aggression on mainland China while intensifying the colonial rule over Korea to turn it into a living hell.

With a deep insight into the prevailing situation, Kim Il Sung decided to advance with large forces into the homeland.

The main unit of the Korean People's Revolutionary Army (KPRA) led by him crossed the River Amnok bordering Korea on the night of June 3, Juche 26 (1937).

He finished combat preparations on the basis of detailed information on Pochonbo.

At 10 p.m. June 4, the battle started with his shooting as a signal.

The main attack was directed at the police substation and sub-county office, post office, fire hall and other enemy's administrative centers were engulfed in flames.

KPRA operatives pasted on trees and walls copies of the Ten-point Programme of the Association for the Restoration of the Fatherland and scattered written appeals and leaflets. The residents stormed into streets in a short time.

Addressing the enthusiastically cheering residents, Kim Il Sung called upon them to turn out in the vigorous struggle for national liberation.

The news of the victorious battle in Pochonbo swept throughout the country, dealing a heavy political and military blow at the enemies.

Upset by the battle, the enemies amassed forces in pursuit of the unit, only to suffer bitter defeats in battles in Mt. Kouyushui and Jiansan Hill.

With the victorious battle in Pochonbo as an occasion, the anti-Japanese armed struggle, which was staged in the areas around Manchuria, rapidly expanded into the whole of Korea and all the Korean people turned out as one in the anti-Japanese resistance.
