It was conducted by KPA large combined units from August 31 to September 1, 1950.

At that time the U.S. imperialist forces were driven to Pusan, giving up most areas of south Korea, by continued attacks of the KPA. They amassed huge military forces of Britain and south Korea as well as their troops and reinforced warplanes, tanks and artillery pieces in the area while escalating the shelling and bombing on the KPA positions.

Under the situation, President Kim Il Sung set forth the 5th operational policy for the first stage of war, which was to encircle the enemy's main forces, concentrated in the narrow area across the River Rakdong, in two directions, wipe them out and destroy the "Pusan base".

According his policy, the KPA soldiers made full preparations for crossing the river and launched the crossing operation on August 31, with dummy crossing and attack at left and right wings.

At the right wing a KPA combined unit went over to an attack on the enemy after its artillery fire and at the left wing another unit started a dummy crossing to lure the enemy.

The KPA soldiers forced their way through the enemy's defense line along the river under a shower of shells and bombs. A KPA unit crossed the river by use of two fording and landing places at 22:00. Another unit successfully finished its crossing by 23:30 after dispatching an advance party to occupy a crossing point.

Then followed the crossing by KPA combined units at the second echelon on September 1. After all, the river-crossing operation was completed overnight.

The successful operation was a victory of Kim Il Sung's prominent strategy, tactics and commanding art and a demonstration of the KPA soldiers' spirit of unconditionally implementing their supreme commander's order.
