The U.S. provoked a war against the Democratic People's Republic of Korea on June 25, Juche 39 (1950), declaring that it would conclude the Korean War in 72 hours.

But, soon after the outbreak of the war, the Korean People's Army went over to counteroffensive and seized nearly whole territory of south Korea in a month, pushing back the provokers to the area south of the River Rakdong and taking the initiative in the war.

Kim Il Sung directed the counteroffensive to the area where the enemy troops were amassed and Seoul City.

Thanks to his superb tactics, Seoul was liberated three days after the start of the war.

Upset by it, the U.S. built up a defence line along the River Han with the south Korean puppet troops and began massively introducing its forces into the war.

To cope with the situation, Kim Il Sung saw to it that the KPA units further enhanced the offensive speed to stamp out the remnants of the puppet forces, thus laying hurdles to deployment of U.S. forces.

The KPA units completely annihilated the "Smith commandos", an advance unit of the U.S. 24th Infantry Division in Osan area and broke through the U.S. defence lines one after another.

KPA seamen sank the U.S. heavy cruiser "Baltimore" with attack of torpedo boats in the waters off Jumunjin several days after the outbreak of the war, while airmen downed "B-29" bombers and other latest warplanes.

Under the command of Kim Il Sung, the KPA liberated over 90 percent territory of south Korea, inhabited by more than 92 percent of its population, only in a month and a half.
