1884 When the Sino-French War started, the French Far East Fleet, under the command of Amédée Courbet, came to attack the northern part of Taiwan Province Province, in order to obtain the coal mine in Keelung (now Keelung City) as the fuel for warships to attack the coast of China, and at the same time, used Taiwan Province Province as a favorable bargaining chip with the Qing Dynasty. 1884, 18 In September, the French army reached the sea outside the chicken coop and launched a gun battle with the Qing army. 654381October 3, the French army captured the city of Geelong. On October 7th and 8th, 65438165438 10, the French army attacked Huwei (now Danshui Town, Taipei County), but was defeated by Chang Sun of Zhangzhou Town, so the Qing and French armies launched a long-term confrontation in the northern part of Taiwan Province Province.

1 1 month, Liu Yingfeng, the garrison commander of Taiwan Province Province in Taichung, was ordered by Liu Mingchuan to enlist Lin Chaodong, a doctor of the Ministry of War, to go north to help, so Lin Chaodong led 500 rural soldiers and two months' rations to Keelung to defend the Great Ulun Fort, and then the Qing army gave up its defense and went to the Great Reservoir (now Anle District of Keelung City) to assist in front-line operations. 1885 65438+1October 9, the French army explored the terrain in Daniupu (now Taoyuan Valley, Jilin Village, Gongliao Township, Taipei County), which clashed with Lin Chaodong's army and was finally repelled by Lin Chaodong. On June 25th, 65438 10, the French army attacked the warm defense line of the Qing army with 1900 troops. The first monthly Meishan campaign broke out between the two sides, and Lin Chaodong led the public to support it. On October 30th, 65438/KLOC-0, he led a night attack on Cao Zhizhong, the overseer of Funing Town, Fujian Province. The two sides fought bloody battles until the early morning of the next day, and then the French army repeatedly attacked with small troops, but they were all repelled by Lin Chaodong. On March 4th, the French army sent 1280 troops to attack the Wenzhou defense line again, and the second monthly Meishan war broke out between the two sides. This time, the French army cut off the front of the Qing army, captured the top of Yuemei Mountain in one fell swoop, and bombarded Lin Chaodong and other battalions with artillery. Finally, the Qing army was defeated. Only Lin Chaodong led Xiang Yong to stabilize his position and successfully assisted the main force of the Qing army to retreat to the south bank of Keelung River. The winning French army ran out of ammunition, and the heavy rain on March 7 caused the river to skyrocket, so it did not cross the river to keep warm.

After that, the two armies continued to confront each other until June 1885 when the French army retreated. 12 in may, Lin chaodong was awarded as a preacher for his meritorious service in helping the war. Although the meritorious service is not high, but won the favor of Liu Mingchuan. Therefore, after the war, more than 30 battalions of Taiwan Province Xiangyong were abolished, while the East Battalion and the Two Battalions were retained and incorporated into the Qing Army. Lin himself was highly valued after the establishment of Taiwan Province Province.
