The General Camp of the Liberation Army (Korean: 광복군총영) was a regional command under the Military Affairs Department of the Provisional Government of the Republic of Korea which was organized in Sangando, Andong Province in 1920.

Then, in May of the same year, Kim Seung-hak, Ahn Byeong-chan, and Lee Tak went to Shanghai as representatives to report on the consolidation of the South and North Manchurian independence movements and the establishment of the unification agency.

Their itinerary was scheduled to depart from the United States in July 1920, pass through the Philippines and China, and arrive in Korea on August 24.

[3] The Provisional Government saw this as an excellent opportunity to raise awareness of the reality of colonial Korea and appeal for Korean independence.

Upon hearing the news of the US delegation's visit, An Chang-ho met with Yi Takh and asked if they could mobilize the youth in Andong (modern-day Dandong, China) for propaganda activities.

He immediately sent a letter to Oh Dong-jin, who was serving as the acting leader of Liberation Corps, to relay the orders of the provisional government.

The order was to organize a military force responsible for "actual combat actions" with the aim of Korean independence.

Subsequently, the actual regional command of the Provisional Government of the Republic of Korea that operated in Sangando was the General Camp of the Liberation Army.

In other words, the activities of each military camp of the Liberation Army, which was dispersed in various places, were reduced due to Japanese surveillance and oppression, and communication between units became difficult.

It operated as an independent organization under the direct jurisdiction of the Military Affairs Department of the Provisional Government of the Republic of Korea.

[2] They carried out domestic guerrilla operations targeting the administrative bodies of the Governor General of Korea and police stations in regions such as Anju, Shinuiju, and Seoncheon.

[5] Since the Korean Liberation Army Headquarters at the time was composed of leaders from various fields, it was inefficient as a fighting force.

As a result, in July of the same year, the General Camp of the Liberation Army was established as the vanguard unit responsible for the front line of the Independence War.

In addition, the General Camp was authorized to establish special operations agencies under its jurisdiction at important domestic and foreign locations.

Therefore, after July 1920, Oh Dong-jin also promoted the establishment of military camps within the country and distributed warning messages to urge vigilance among those working for enemy institutions and the general public.

Note: However, these plans by Oh Dong-jin for domestic activities were difficult to realize because of the strict surveillance and brutal suppression by the Japanese invaders at that time.

They aimed to demonstrate the will of the Korean people for independence by carrying out acts of resistance such as bombing government offices and assassinating officials in Seoul, Pyongyang, Seoncheon, Shinuiju, and other locations, coinciding with the visit of the US congressional delegation.

In this way, the members successfully passed through Uiju, Sakkju, and Guseong, and on the morning of July 30, they entered Anju, South Pyongan Province, without major incidents.

At that moment, Jang Deok-jin quickly pulled out a pistol from his pocket and aimed it at six different spots, including Kudo's face, firing bullets.

After reassuring the startled residents who witnessed the sudden gunfire, Moon Il-min and his group changed clothes at a nearby farmhouse to evade police pursuit and urged to continue their journey.

Upon entering Pyongyang, they encountered another person suspected to be an investigator, but the members' demeanor was so inconspicuous that they didn't attract any attention.

[3] Unfortunately, three days before the U.S. congressmen's arrival in Seoul, on the night of August 20, Kim Yeong-cheol and his group were arrested by enemy police, and they were not only captured, but their bombs, guns, and numerous documents, including urgent warning letters, were seized.

Moreover, the swift infiltration and bold activities of Kim Yeong-cheol, Ahn Gyeongshin, Jang Deokjin, and others were commendable achievements that amazed and inspired many people.

[5] The most intense battle conducted by the Oh Dongjin Battalion was the so-called "infiltration operation" where they entered the domestic territory and attacked and destroyed the Japanese colonial institutions.

Through this operation, mainly targeting Japanese police stations, the colonial rule in the border regions was effectively paralyzed.

Additionally, individuals like Moon Hak-bin, Kong Ju-hwan, and Lee Nung-hak were dispatched to Pyeongbuk, Yeokdong Province, to recruit military funds and support the cause.
