The General Staff Headquarters, which received formal approval from the Provisional Government on June 26, 1924, included each prefecture in Jian, Fusong, Changbai, Ando, Tonghwa, and Yuhwa.

After 1928, there was division over the direction of the independence movement, and its power weakened to the point of joining the National People's Prefecture.

[3] In the spring of 1922, several independence movement groups in the southern Manchuria region, including the Korean Independence Group, Seoro Gunjeongseo, Bohapdan, Gwanghandan, and the Liberation Army General Headquarters, held a meeting for the unification of the South Manchurian people and agreed to form the Unification Military Government.

[3] In May 1924, a month after the announcement of the 'Declaration,' the General Staff Headquarters in Manchuria (from now on referred to as the Army Advisory Office) was established and centered on the independence forces that participated in the 'Declaration.'

Still, the jurisdiction of the Civil Affairs Department was divided into 13 local administrative districts, and its primary function was to collect military funds.

A representative example of the anti-Japanese armed struggle waged by the General Staff Headquarters unit was the attack on Makoto Saito, the Governor-General of Korea, at Masitan on the banks of the Yalu River on May 19, 1924.

Accordingly, a special force was formed with eight members of the 1st Platoon of the 2nd Company, and an ambush was set up in Masitan Valley, Wiwon County, North Pyongan Province.

In March 1925, executives from five companies met at Gomaryeong (古馬嶺) in Gajaehyeon to establish an operational plan for the domestic invasion.

The army was able to resist this and preserve its basic capabilities, but Choi Seok-soon, 39 members, including company commander Jeon Chang-hee (田昌禧), were killed and tortured.

General Staff Headquarters members who suffered significant damage in Gomaryeong reorganized their organization and sought ways for a new career path.

However, to make up for the damage suffered in Gomaryeong and maintain the organization, they had to focus on civil affairs activities for the Korean community.

On August 8 of the same year, the executive team was announced with Yoon Seong-Hwa [尹聖佐, = Yun Se-yong (尹世茸)] as the Chairman of the Central Council.

In June 1925, the ‘Mitsuya Agreement (三矢協約)’ was signed between the Japanese Government-General of Korea and the warlord of the Fengtian clique.

In 1929, some members of the General Staff Headquarters moved to the National People's Prefecture, and those led by Kim Seung-hak created the Innovation Council.

On May 19, before the formal approval of the Provisional Government, Governor Saito boarded a patrol boat under the pretext of inspecting the security of the border region, ambushed him as he descended the Yalu River, and drove him into chaos, one of the most notable activities of the Army Advisory Office.

Chosan (楚山), Wiwon (渭原), Manpojin (滿浦鎭), and Gajeonhyeon in North Pyongan Province were the main military bases and stages of General Staff Headquarters's activities.

In the early days of the establishment of the Army Advisory Office, three of the five companies were deployed to Gajae-hyeon, and the remaining units were located in Hwanin-hyeon and Tonghwa-hyeon.

In particular, they went into the country to raise military funds, punish pro-Japanese factions, and carried out activities to attack Japan's ruling institutions.

The purpose was to understand the surrounding situation, report instructions from headquarters, sympathies of the Japanese military, etc., and communicate with them.

[3] The General Staff Headquarters also conducted civil affairs activities to protect and govern the Korean community within its jurisdiction.

Because the area under the jurisdiction of the Army Advisory Office was mainly mountainous, it was realistically impossible to build large-scale facilities.

[3] While armed activities slowed down following the Battle of Gomaryeong, the General Staff Headquarters worked for the stability of Korean society.

Baek Si-gwan (白時觀) was the Chairman of the central meeting, and Kim So-ha (金筱廈) was the head of the civil affairs department.

In particular, when the Mitsuya Agreement was signed, and Japan and China checked and blocked the activities of the independent army, they reorganized their organization and strengthened their power.

In October 1924, an incident occurred in which Chae Chan (= Baek Gwang-un), the Chairman of the Cham Council and the commander of the 1st Company, died after being attacked by Tonguibu members.

The jurisdiction of Chamuibu is centered around Jianhyeon (輯安縣), including Gwanjeon (寬甸), Hwanin (桓仁), Tonghwa (通化), Fusong (撫松), Jangbaek (長白), Ando (安圖), and Yuhwa (柳).

[4] In 1928, an incident occurred in which Han Eui-je, Chairman of the Finance Committee, organized a pro-Japanese group and betrayed the General Staff Headquarters.

Due to these circumstances, the General Staff Headquarters focused on anti-Japanese armed struggle and eradicating pro-Japanese elements in Manchuria instead of entering the country through guerrilla warfare.

[3] When the Innovation Council, which gave birth to the three-part integration movement, was formed in 1928, Chairman Kim Seung-hak participated in it and declared its disbandment.

Meanwhile, Lee Yeong-hee (李永熙), Acting Chairman of the Central Council, worked with 15 of his subordinates in the Gajeonhyeon area and promoted the revival of the Army Advisory Office, but it was not realized.
