Bongodong Independence War was not a one-day battle on June 7, the day of victory, but a war that included all three-day battles from June 4 to June 7, 1920.

After the establishment of the Provisional Government in Shanghai in1919, the first Korean military army, ‘Daehan Gunmudodokbu’ established in Bongodong by General Choi Woonsan. The Daehan Gunmudodokbu soldiers were armed and elite soldiers who had been trained for nearly 10 years and had gained a lot of experience in battles between the warlords of Northeast China.
The Provisional Government of the Republic of Korea declared the Year of the War of Independence in 1920.
General Choi Woon-san and his brothers had been preparing for the independence of Korea by building a military base for the Bongodong Independence Army and training soldiers, in anticipation of the war of independence against Japan

General Choi Woonsan's The Daehan Gunmudodokbu frequently carried out the Domestic Invasions of the Independence Army destroying Japanese military border posts and military police offices army as part of the strategy of the war of independence from March 1920 to the Battle of Bongodong.
The Japanese government recorded that The Daehan Gunmudodokbu, which reported "the most frequent armed invasion" among independent military groups in North Gando, attacked the border's Army 36 times between March and June 1920.

The purpose of the Domestic Invasions of the Independence Army was to disrupt Japan's ruling order, increase instability in the border area, and raise the hostility and patriotism of Korean people. The invasions also aimed to supplement and strengthen the armed forces of the Independence Army by capturing weapons and the spoils of battle. Additionally, the invasions were carried out to prepare for war and gather intelligence on the Japanese army's operations.

General Choi Woonsan rushed to integrate armed independence forces in North Gando ahead of the impending war of independence and raised military funds for the integration by selling his own land
The armed independence forces in North Gando engaged in intensive discussions on unification. Finally, on May 19th, the united independence army, 'Daehan Bukrodokgunbu' was established in Bongodong under the condition that General Choi Woonsan would provide weapons and military funds. His older brother, General Choi Jin-dong, became the supreme commander of the Daehan Bukrodokgunbu.

General Choi Woon-san obtained intelligence on the Japanese army's plan to attack across China's borders to subdue the Independence Army, despite the diplomatic risks.
It was an inevitable war that must be won. General Choi Woon-san evacuated all the residents of Bongodong to another place 15 days before the Bongodong Independence War and prepared for the Japanese invasion.
For victory, The supreme commander of the Daehan Bukrodokgunbu, General Choi Jin-dong and General Choi Woonsan devised an ambush strategy in Bongodong, and the beginning of this operation was the domestic invasion of Gangyang-dong.

The Independence Army unit of Daehan Bukrodokgunbu, known as 'Sinmindan', carried out an attack on the border guards at Gangyang-dong, crossing the Tumen River on June 4th and then withdrew to Samdunja across the Tuman River to monitor the movements of Japanese troops.
The Japanese army, which was attacked by the Independence Army, did not respond immediately but instead prepared to attack Bongodong on a large scale gathering troops including the 19th Division in Hatan-dong. After two days of preparation, the Japanese army began fighting at Samdunja on June 6th. The Japanese troops crossed the Chinese border to subjugate the Independence Army by dividing into two using the excuse of pursuing the Independence Army which had launched the initial attack.

The Daehan Bukrodokgunbu lured the Japanese army by pretending to retreat to Bongodong. After fighting with the independence forces in Ansan, located on the way to Bongodong, the Japanese army crossed Goryeoryeong Pass and invaded the village of Jungchon of Bongodong on June 7. General Choi Woon-san and General Choi Jin-dong, the supreme commander of the Daehan Bukrodokgunbu, was already aware of the Japanese military tactics. After clearing out Jungchon village, the Independence Army lay in wait for the Japanese troops in an ambush around the mountains on the three sides surrounding Sangchon, the location of the military headquarters of the Daehan Bukrodokgunbu.

The Japanese army, having found that Jungchon, where they believed the Independence Army headquarters was situated, was empty, wrongly assumed that the Independence Army had abandoned the military base and fled elsewhere. They then advanced towards Sangchon to retreat via Bipa-dong, only to be completely caught in the operation of the Daehan Bukrodokgunbu.

General Choi Jin-dong was quietly watching the Japanese army pass through the ambush point of the Independence Army at Bongchobong, the highest point of command. General Choi Jin-dong rang a gunshot to signal the start of the attack, and a concentrated attack of the Daehan Bukrodokgunbu began with gunfire shaking the mountain

In the battle that began at 12:20 pm on June 7 in Bongodong Sangchon, the Daehan Bukrodokgunbu overwhelmingly dominated. However, when the ambush unit on the western mountain retreated, the independence army temporarily fell into a disadvantageous situation. But at around 4:30 pm, suddenly heavy rain and large hailstones fell from the sky, causing confusion among the Japanese troops. The weather was also in favor of the independence army. The Japanese army, which had already been hit enough to lose its fighting spirit, decided to retreat.
The Japanese army wrote in their report after the Battle of Bongodong that they fought fiercely through heavy rain and hail, enduring the "skin-ripping and flesh-cutting" cold and pain, in order to reach the high ground where the Independence Army was located. This shows of how intense the battle was between the Independence Army and the Japanese army.

General Choi Woon-san and Supreme Commander General Choi Jin-dong detected that another Japanese support unit was advancing from Bipadong, where the Japanese were retreating. They ordered General Kang Sang-mo, who led the second company, to attack the Japanese troops from both sides. This tactic, which caused the Japanese troops to shoot each other in the rain without seeing the front, dealt a fatal blow to the Japanese military.
In this three-day battle, the Independence Army of the Daehan Bukrodokgunbu won a landslide victory.

In 1920, the Provisional Government's military affairs department published in the Independent Newspaper recorded 157 Japanese soldiers killed, 200 seriously injured, and 100 lightly injured. However, the independence fighters who participated in the battle, including General Choi Woon-san's wife, Lady Kim Seong-nyeo, recorded that there were hundreds of Japanese soldiers killed, and this is the same as Hong Beom-do's diary, which says about 500 Japanese soldiers died.

So far, the general perception of the Bongodong War of Independence has been limited to a heroic narrative about Hong Beom-do as an individual.
Furthermore, there are problems and limitations in the research and description of the Battle of Bongodong. It is necessary to look into how the subject of the victory in the Battle of Bongodong, the Daehan Bukrodokgunbu, was replaced by the 'Daehan Dokripgun' and how Hong Beom-do, who was the regiment commander, was changed to the overall commander in the description of the battle, Any inaccuracies should be corrected.

The Bongodong War of Independence should be properly evaluated as a history of victory that the Daehan Bukrodokgunbu overwhelmingly defeated the Japanese army by preparing perfectly with armament and tactics.

We hope that the role of General Choi Woon-san, who laid the foundation for the independence war by devoting all his fortune and led the victory, and the sacrifice and dedication of numerous ancestors of the independence army who accompanied him will be properly recognized and remembered.
