November 8th On November 8, when the peasant army launched a fierce attack on Yiyin and Mune against the suppressing forces divided into three divisions, the government forces were driven back and retreated to Gongju Kamnyeong. Jeon placed his army so that the rebels stretched sixteen kilometers, from Panchi to Mount Bonghwang. Jeon was at the center of this line, surrounded by flags and riding on his white horse. The government forces defended the sides (Hyopyo, Ungchi, Mount Bonghwang), while the Japanese were stationed in Ugeumchi proper. At 10:00 am, the rebels charged at Ugeumchi. He sent two battalions of the Donghak Peasant Army advanced from Gyeongcheon to the southeast of Gongju Castle, and another detachment began pressuring the government forces, stationed in Iin, from the southwest to lure them away so that the major rebel forces would not meet a large governmental army in Ugeumchi. Finally, around 3 p.m., the first division crossed Panji and attacked Yiyin and Hyopo, diverting the attention of the government forces in that direction. At the same time, the second division, consisting of about 10,000 soldiers, advanced towards the government forces stationed in Iin. The other 30,000 rebels were crossing Ugeumchi. However, they encountered a
Japanese battalion of 280 soldiers. The Japanese gathered the Korean forces into Ugeumchi. Japanese Lieutenant Moriya, who was in overall command, repelled the attack with about 280 Kyungricheong soldiers and defended Ugeumchi with a Japanese battalion. Throughout the night, both sides fiercely confronted each other, lighting fires and firing guns and cannons. As the day broke, they entered into a decisive battle.
November 9th On the morning of November 9, the deployment of both sides revealed that the Donghak Peasant Army had advanced from Panji in the east to Bonghwangsan in the west, spanning about 40 to 50 li (about 16 to 20 kilometers). Especially, the main forces had advanced to a mountain located 500 meters ahead of Ugeumchi. The Pyeongwiyeong and Gamyeongbyeong were responsible for the frontal and right defenses, including Geumhakdong, Woongchi, Hyopo, and Bonghwangsan. The Japanese troops, centered around some Kyungricheong soldiers and the disbanded 19th Regiment, were scattered and deployed at Ugeumchi and Gyunjunsan. The peasant army surrounded Gongju from three sides (Hyopo, Ungchi, and Ugeumchi) and launched an offensive toward Ugeumchi, the key point of entry into Gongju. At that time, the government forces led by Yi Gyu-tae and Yi Du-hwang were stationed on the east and west sides of Ugeumchi, and the Japanese forces were stationed at the highest peak of Ugeumchi. In addition, troops trained by the Japanese, including Yi Jin-ho (1867–1943) leading the Military Training Division and Seong Ha-yeong leading the Military Administration Bureau, were deployed along the defense line. Riding the momentum of victory, the peasant army launched a full-scale attack towards the suppressing forces' positions in Ugeumchi. The suppressing forces occupied advantageous high points in terrain, including Gyunjunbong (犬蹲峰), and waited for the peasant army. The peasant army was in a disadvantageous position, as they had to attack from lower ground towards the mountaintop. The suppressing forces, positioned between Ugeumchi and Gyunjunbong, used the small ridges as shields to observe the peasant army from above. They opened fire when the peasant army approached and concealed themselves, and repeated this pattern when the peasant army advanced through the narrow ridges in the valley of Ugeumchi. However, despite the constant one-sided shooting and witnessing the peasant army continuously "waving flags, beating drums, and bravely climbing up, facing death," the officials' recording of the unyielding spirit of the peasant army expressed their bone-chilling and cool-hearted thoughts on their actions. At 10 a.m., the Donghak Peasant Army began its attack towards Ugeumchi, and at the same time, the other division of about 10,000 soldiers, who had faced Samhwasan, advanced towards the rear mountain of Osil. In the battle, which took on the characteristics of a highland battle, the Donghak Peasant Army, charging with spears and various firearms, attacked the government forces and Japanese troops, who defended from advantageous positions. However, the Donghak Peasant Army, despite suffering heavy casualties, continued the attack without yielding. This defense battle continued until the afternoon, but the Donghak Peasant Army, unable to break through the aggressive defense of the government forces, could not avoid retreating. According to the records of the government forces, the peasant army attempted to break through Ugeumchi over 40 to 50 times but could not overcome the unfavorable terrain and the superior firepower of the government and Japanese forces, resulting in numerous casualties and a retreat. Because of their weak weapons, they were unable to cross Ugeumchi. The Japanese used cannons and rifles, and had proper military training. Although small groups of rebels crossed the 'death line' more than forty times, they were all shot down. Meanwhile, a portion of the peasant army attempted to bypass the Ugeumchi Valley and occupy Duri Peak to advance toward Gongju, but as the main force was defeated at Ugeumchi and the government and Japanese forces blocked their retreat route, this operation also failed. In the end, the peasant army had to retreat towards Nonsan, suffering a defeat in the Battle of Ugeumchi. Jeon Bong-jun sent a letter to the government forces during the retreat, appealing for Koreans to fight together against the Japanese, but it had no effect. As a result, the peasant army's advance towards Seoul was thwarted, and the Donghak Peasant Revolution ended in failure.
Battle of Hyopyo Meanwhile, in Hyopyo, the 10,000 rebels took advantage of the government army's negligence in defense and attacked the mountain peak all day long. They captured various peaks, but whenever the governmental forces seemed to break, they were instantly reinforced by the Japanese. The battle was expressed by a spectator of the battle: The Donghak Peasant Army, which was unable to break through the strong defenses of the government and Japanese troops despite making great sacrifices, ended up completely retreating toward Noseong and Nonsan on the afternoon of the 11th, and Jeon Bong-jun advised the Koreans not to fight among themselves and keep up the fight. In addition, thousands of Donghak peasant troops stationed in Hyopo also lost morale and were ambushed by about 10 disguised government soldiers and retreated toward Gyeryongsan Mountain. The Donghak Peasant Army, which attempted to occupy Gongju and then move north to Seoul, was thwarted in Ugeumchi. == Aftermath ==
