General Choi Woon-san was a little-known hero of the Korean armed independence movement.
He was a wealthy landowner who owned ten provinces, including Bongodong, Domun, Seokhyeon, Seodaepa, Sipripyeong, and Yangsucheonja.
In addition to his vast land holdings, he was an entrepreneur who operated several factories producing daily necessities such as bean oil, noodles, bottles, matches, and soap.
He also had close ties with independence fighters in Russia while exporting cattle and grain in large quantities

General Choi Woonsan built Shinhan Village in Bongoh-dong and called upon his compatriots to make his village a forward base for the anti-Japanese armed independence struggle.
He operated a military unit and independently organized the independent forces by gathering over 100 soldiers selected from the Chanese Army and patriotic young men who came to become independent fighters and training them at Bongodong Military Academy.

In 1915, General Choi Woon-san cleared the forest in Bongo-dong to create a large training ground and three barracks for the growing number of independence fighters. He personally financed all military expenses.

General Choi Woon-san and his brothers also led the 3.1 Declaration of Independence in northern Gando, organizing ceremonies on March 26, 1919 in Baekcho-gu, Wangcheong County and on May 18 in Yangshucheonja.

General Choi Woonsan established ‘the Daehan Gunmudodokbu’, a fully armed unit composed of over 600 elite soldiers who had been trained and nurtured since around 1910 with the establishment of the Provisional Government of the Republic of Korea in Shanghai in 1919.
The name "Daehan," meaning the Republic of Korea, was attached to the Dodokbu, which had started as a private unit, to signify the unit as the first military force of the Republic of Korea.(All of General Choi Woonsan's brothers became the main pillars of the Daehan Gunmudodokbu, with his older brother Choi Jin-dong taking over as the commander-in-chief after resigning from the Chinese army.)
Additionally, General Choi Woon-san co-founded ‘the Bukrogunjeongse’ in Seodaepa and the Yeonseong Military Officer Academy in Sipripyeong with Seo-il.
He provided food, weapons, and military funds to support these organizations.

In 1920, when the Provisional Government declared the year of the War of Independence, General Choi Woon-san began preparing for a full-scale independence war.
He sold a large plot of land he owned in Seok-hyeon and used the funds to purchase weapons from the Czech Legion to equip all the independence forces gathered in Bongodong.
Thanks to Choi Woon-san's financial power and extensive network, the independence army was fully equipped, which played a crucial role in its victory over the Japanese army in Bongo-dong and Cheongsan-ri.
Throughout the independence movement, there were few independence groups or patriots in the Gangdo who did not receive financial support from General Choi Woonsan.

Between March and June of 1920, General Choi Woonsan, who led the Daehan Gunmudodokbu, carried out frequent domestic invasions of the Japanese military border posts and military police offices as part of the strategy of the war of independence.

Furthermore, General Choi Woonsan integrated the armed independence forces in North Gando into the Daehan Bukrodokgunbu ahead of the impending war of independence

As General Choi Woon-san expected, the Japanese army invaded Bongo-dong with a large army to subdue the independence army on June 7th. However, the Independence Army of the Daehanbukrodokgunbu prepared for the war by purchasing new weapons that were superior to the Japanese army and preparing for an ambush by making a trench in Bongodong.
General Choi Woon-san and the Independence Army of the Daehanbukrodokgunbu achieved a great victory by employing an elaborate strategy to lure the Japanese army to Bongo-dong.

The long-standing efforts of General Choi Woonsan, who had established, nurtured, and continuously expanded the independent army since the loss of national sovereignty, yielded historical results.
In the Bongo-dong and Cheongsan-ri War of Independence in June and October 1920, the victories became a shining symbol of national self-determination, declaring Korea's will for independence to the world.

Even in the 1930s, General Choi Woon-san led several armed independence wars to victory, including the Battle of Ussuri River, Battle of Rajagu, Battle of Daehwanggu, Battle of Domundae, Battle of Ansanri, and Battle of Daejeon Jaryeong.

General Choi Woonsan devoted his life to the struggle for the independence of the Republic of Korea, depleting all his possessions in the armed struggle.
Despite facing six prison sentences and severe torture, he did not step back and became a model of noblesse oblige that transcends time.
