The army of the Daehan Empire was gradually reduced while the Japanese Empire exposed its intent of aggression without disguise.

In 1907 immediately before the disbandment of the military, the 4th battalion was set up in Jeolla-do with the headquarters in Gwangju.

Outstations of the 4th battalion were established in Gangjin and Jeonju and a force 50 strong was sent.

It is still uncertain whether an outstation in Gangjin was located in the site of the past Byeongyeong.

However, it can be guessed that although Jeolla Byeongyeong was removed, Gangjin still remained as a strategic point of the Jeolla area.

After the army was disbanded, they joined loyal troops under Shin Nam-il's command, providing outstanding military strength, contributing to being active in the war of Uibyeong(righteous armies). With the undisguised desire of Japan for invasion, the war of Uibyeong was developed from every corner of the country.

Since Gangjin shared the branch of Mt. Jirisan with Jangheung and Boseong, it had advantage of the activity of Uibyeong. This area was greatly influenced by Choi Ik-hyeon and Im Byeong-chan troops at one time. Famous commander of Uibyeong was Shin Nam-il and many of Gangjin people joined his army.

Shin Nam-il gathered soldiers in Hampyeong, Nampyeong, Boseong, and Jangheung in 1908. He played an active part in Nampyeong, but got arrested in August of the same year.

Jeolla Byeongyeong built its fortress after the removal to Gangjin and controlled 52 Ju and 6 Jin in the province of Jella-do. In 1895 during the Baekje Period, it was the seat of Dogang-gun, called Gogun-myeon, and controlled 24 Dong and Ri, including Sakdun and Baekyang. In 1914, it was reorganized to the present administrative district.

In 1931, it was changed its name to Byeongyeong-myeon because there was Byeongyeong Fortress.
