It was one day in September Juche 40 (1951) that he made an on-site inspection of the Height 1237.3 neighboring the Height 1211 to indicate an operational line for defending the Height 1211.

At that time, he called for paying deep attention to the living of servicepersons, saying that the commanding officers were obliged to look after their living.

After the inspection, he sent a large amount of bean to soldiers at the front to improve their diet.

Encouraged by his loving care, the servicepersons reliably defended the height.
