One of them says, "General Kim Il Sung ferried guerrillas across the River Amnok with a sheet of paper."

The legend, spread after the Pochonbo Battle on June 4, Juche 26 (1937), is based on the crossing of the Amnok River by a unit of the Korean People's Revolutionary Army (KPRA).

At that time, the Japanese imperialists, in a bid to prevent the KPRA from advancing into the homeland, installed over 300 police stations and sub-stations and deployed huge armed forces in the northern border area.

They boasted of having turned the area into an "impregnable fortress".

The President mapped out a plan to lead the KPRA main unit to enter the homeland stealthily, attack the enemy and get away from the area quickly.

After acquainting himself with the enemy's movements and the geographical conditions, the President, guiding the main unit, crossed the River Amnok through Kouyushui Barrage on the night of June 3.

A raft bridge was ready at the barrage. It was laid across the river by some members of the unit beforehand, as directed by the President.

After entering the homeland, the KPRA unit fought a victorious battle in Pochonbo on June 4 under the command of the President.

It was hard for the Japanese imperialists to understand how the KPRA unit could cross the river stealthily and vanished like phantom after the battle.
