The Korean Independence Army, commanded by General Kim Chwa-chin, formed the military of Shinmin Prefecture.

The Korean Independence Party established 26 military districts centered on the Middle East Railway in North Manchuria and fought against the Japanese.

At this time, numerous Chinese military units advocating anti-Manchurian and anti-Japanese activities were organized in the Manchurian area and fought against the Japanese and Manchukuo armies.

In these units, a part of the Zhang Haek-ryang army, a security guard group, or even some magic soldiers participated.

[6][1] Prior to this, on November 2, 1931, the Korean Independence Party set new activity goals in response to the Japanese occupation of Manchuria.

They discussed joint Korean-Chinese operations with 3rd Army Commander Yang Mun-hwi (楊文揮) and Go Bong-rim.

The Korean-Chinese combined forces killed 10,000 people in places such as Wishaha, Ilmyeonpi, Ogilmil, Milocham, Dongbinbangjeong, and Uiran.

There was a fierce battle with the army, but due to lack of food and ammunition, they suffered a crushing defeat and were dispersed.

Ji Cheong-cheon, commander-in-chief of the Korean Independence Army, personally led Chief of Staff Shin Suk and Iljidaegun (一支隊軍) and fought a fierce battle in Uiran, but retreated to Tongha County (通河縣) in Heilongjiang Province and recovered the unit.

Ahn Jong-seon, the commander of the separate unit, achieved a successful victory by temporarily recapturing the fortress on March 3 through a joint operation with the Gobongrim unit of the Chinese 3rd Tiger Army, but he was not able to hold the fortress for long, and Cha Cheol The 3rd, 4th, and 5th battalions led by (車澈), Ya Sang-gi (也相奇), and Jeon Buk-bin (全北賓) are led by the 3rd and 4th female commanders Yu Ji-gwang (劉志光) and Gung Yeong-mu (劉志光) of the Chinese Tiger Army .

Within a month, the independence army was assembled, Kim Chang-hwan (金昌焕) was appointed as acting commander-in-chief, the troops were reorganized, and they began training.

Ssangseongbo was a place of great strategic value as it was a key point of the Japjang Line railway and a distribution center for important products in Northern Manchuria.

On September 3, when General Lee Cheong-cheon, commander-in-chief, led the troops from the Heilongjiang region, the independence army was reorganized and Kim Chang-hwan became deputy commander and marched toward Ssangseongbo on the 19th.

The Allied forces, who recaptured Ssangseongbo for the second time, immediately organized their loot and prepared for an enemy counterattack.

[6] In the early morning of the 15th, the enemy advanced with a force of about one division from Huangga Dun (黃家屯) to Sadohaja via the direction of Idoha.

Our troops' losses were minimal, and the enemy abandoned a large number of weapons and ammunition throughout the year.

The victorious Korean-Chinese allied forces entered the fortress, reassured the residents, and captured more loot than during the Battle of Sadohaja.

It was not feasible to immediately attack Yeonganseong Fortress, where a large army was stationed, so the main force was moved to the mountainous area between Wangqing and Dongnyeong.

The topography of Daejeonjaryeong is a two-character rugged hill with a valley about 20 li in length, and on either side of it is a deep mountainous jungle area with cliffs hundreds of meters high.
