In September 1950, the U.S. forces began a "general offensive" in order to turn the war situation in favor of them.

As part of the offensive, they launched an operation to land on Inchon past Wolmi Island with several hundred warships boarded with 50,000 troops, supported by more than 1,000 planes.

There was only a KPA coastal artillery company with four guns on the island.

The artillerymen sank many warships in the first- and second-day battles, delaying the enemy landing.

Ahead of a life-and-death battle, the company commander, Ri Tae Hun read a letter of oath to Supreme Commander Kim Il Sung, which was signed by the remainders.

The letter represented their death-defying resolution to fight the aggressors to the last man.

It also reflected their absolute trust in the supreme commander.

For them, the supreme commander was precisely their motherland and vice versa.

Thereby, they shouted "Long Live General Kim Il Sung!" and "Long Live the Workers' Party of Korea!" in the last battle.

The U.S. forces' landing was delayed for three days by their heroic fighting.
